BioRhythm Privacy Policy

Effective date: July 14, 2026
Last updated: July 14, 2026

1. Introduction

This Privacy Policy explains how information is handled in connection with the BioRhythm mobile application, its widgets, related webpages, advertisements, purchases, support communications, and associated services, collectively referred to as the “Service.”

The Service is operated by:

Marek Hovorka
Sole trader operating under the business name MH Softworks
Identification No. (IČO): 17399408
Stavařská 735
686 05 Uherské Hradiště
Czech Republic
Email: hello@mhsoftworks.com
Website: https://mhsoftworks.com

MH Softworks is a business name used by Marek Hovorka. It is not a separate company or legal entity.

In this Privacy Policy, “BioRhythm,” “MH Softworks,” “we,” “us,” and “our” refer to Marek Hovorka as the operator of the Service.

This Privacy Policy is intended to explain:

  • what information may be processed;
  • whether information remains on your device or is transmitted;
  • why information may be processed;
  • which third parties may process information;
  • how long information may be retained;
  • which rights and choices may be available to you.

By downloading, installing, accessing, or using the Service, you acknowledge that you have read and understood this Privacy Policy.

Where applicable law requires consent, processing based on consent will take place only after the required consent has been requested or obtained.

Nothing in this Privacy Policy waives or limits any right that cannot lawfully be waived or limited.

2. Scope

This Privacy Policy applies to:

  • the BioRhythm Android application;
  • BioRhythm home-screen widgets;
  • advertisements displayed through the application;
  • purchases made through Google Play;
  • the BioRhythm privacy, terms, support, and informational webpages;
  • support requests and other communications sent directly to us.

This Privacy Policy does not govern applications, websites, advertising networks, payment processors, operating systems, application stores, device manufacturers, or other services that we do not control.

Third parties may process information under their own privacy policies, terms, legal obligations, and technical systems.

3. General Privacy Design

BioRhythm is designed as a primarily local application.

The main biorhythm functionality does not require:

  • creation of a BioRhythm account;
  • registration with us;
  • submission of your real name;
  • submission of your email address;
  • transmission of your birth date to a server operated by us;
  • transmission of calculated biorhythm results to a server operated by us.

Information entered for the main calculation features is processed and stored locally on the device, subject to the limitations described in this Privacy Policy.

The application does, however, integrate third-party services for:

  • advertising;
  • consent and privacy-choice management;
  • Google Play purchase processing;
  • application distribution and platform functionality.

Those third-party services may independently collect or process technical, device, advertising, diagnostic, transaction, consent, security, and usage information.

4. Information Processed Locally on Your Device

Depending on the features you use, BioRhythm may process and store the following information locally:

  • your date of birth;
  • a date selected for a biorhythm calculation;
  • calculated physical, emotional, intellectual, intuitive, or other cycle values;
  • application settings and preferences;
  • language and appearance preferences;
  • onboarding completion status;
  • widget configuration and state;
  • consent-related application state;
  • information indicating whether the Remove Ads feature appears to be active;
  • temporary interface and process-restoration state;
  • other information reasonably necessary for local application functionality.

This information is used to:

  • perform biorhythm calculations;
  • display calculation results;
  • restore application state;
  • maintain user-selected settings;
  • provide widgets;
  • determine whether advertisements should be displayed;
  • operate the application as requested by you.

We do not intentionally receive the locally entered birth date or calculated biorhythm results on a server operated by us.

Because this information normally remains only on your device, we generally cannot:

  • see it;
  • access it remotely;
  • retrieve it;
  • correct it;
  • restore it;
  • export it;
  • delete it on your behalf.

You can generally remove locally stored information by:

  • changing or deleting it within the application, where that option is available;
  • clearing BioRhythm application data through Android settings;
  • uninstalling the application.

Clearing application data or uninstalling the application may permanently remove locally stored information and settings.

We do not guarantee that deleted local data can be restored.

5. Device Backups and Device Transfers

BioRhythm is configured to disable standard Android application backup.

However, operating systems, device manufacturers, device-transfer tools, rooted or modified devices, backup software, enterprise systems, or other third-party mechanisms may behave differently or may copy information independently of the application’s intended configuration.

We do not control:

  • device-level backup systems;
  • manufacturer-specific migration tools;
  • Google account backup settings;
  • local computer backups;
  • third-party backup applications;
  • forensic tools;
  • rooted or modified operating systems;
  • data copied by the user.

Accordingly, we cannot guarantee that information stored locally will never be copied, cached, recovered, transferred, or retained by a device, operating system, backup provider, or other third party.

You are responsible for securing your device and any backup or migration system that you choose to use.

6. Information We May Receive Directly

6.1 Support communications

If you contact us, we may receive:

  • your name or chosen identifier;
  • your email address;
  • the content of your message;
  • screenshots or screen recordings;
  • files or attachments;
  • application version information;
  • device model and operating-system information;
  • diagnostic or troubleshooting information;
  • any other information that you voluntarily provide.

We use this information to:

  • respond to your request;
  • investigate technical problems;
  • provide support;
  • protect the Service and our legal rights;
  • detect abuse or fraudulent requests;
  • maintain appropriate business records;
  • comply with legal obligations;
  • improve the Service.

Do not send sensitive or confidential information unless it is genuinely necessary for your request.

In particular, you should avoid sending:

  • medical records;
  • government-issued identification documents;
  • complete payment-card details;
  • account passwords;
  • authentication codes;
  • information concerning another person without authority;
  • any information unrelated to the support request.

6.2 Voluntary submissions

We may receive other information that you voluntarily submit through email, a web form, an application-store review, a survey, or another communication channel.

We may use such information for the purpose for which it was submitted and for reasonably related support, administrative, security, legal, and service-improvement purposes.

7. Advertising

The free version of BioRhythm may display advertisements provided through Google AdMob and the Google Mobile Ads SDK.

Google, advertising providers, mediation partners, technology providers, and other participants in the advertising ecosystem may collect, receive, store, use, infer, combine, or disclose information such as:

  • Internet Protocol address;
  • Android advertising identifier, where available;
  • application-set identifiers;
  • device identifiers;
  • account-related identifiers made available by the platform;
  • advertisement impressions;
  • advertisement clicks;
  • advertisement views and interactions;
  • application interactions;
  • session and usage information;
  • diagnostic information;
  • crash and performance data;
  • device model;
  • operating-system version;
  • language;
  • screen characteristics;
  • network information;
  • approximate geographic location inferred from an IP address;
  • consent status and privacy choices;
  • fraud-prevention signals;
  • information used for attribution, advertising measurement, reporting, frequency capping, security, and abuse prevention.

The exact information processed may depend on:

  • the installed version of BioRhythm;
  • the version of the Google Mobile Ads SDK;
  • your device and operating system;
  • your country or region;
  • your privacy and consent choices;
  • your Google account settings;
  • whether an advertising identifier is available;
  • whether personalized or non-personalized advertisements are permitted;
  • the advertising provider serving a particular advertisement;
  • changes made by Google or another advertising participant;
  • applicable legal requirements.

Advertising providers may use automated systems to:

  • select advertisements;
  • personalize advertisements where permitted;
  • serve contextual or non-personalized advertisements;
  • measure advertisement performance;
  • prevent repeated advertisement exposure;
  • detect invalid traffic;
  • prevent fraud and abuse;
  • enforce legal and contractual requirements.

We do not determine all information collected by Google or all purposes for which Google independently processes information.

Google may act as an independent controller, processor, service provider, contractor, or another legally defined role depending on the processing activity and jurisdiction.

Google’s privacy practices are governed by Google’s own documentation, including:

We are not responsible for Google’s independent systems, policies, retention periods, security practices, or subsequent processing, except to the extent that applicable law imposes responsibility on us.

8. Consent Management and Privacy Choices

BioRhythm uses or may use the Google User Messaging Platform, also known as Google UMP, to request, record, refresh, and communicate advertising privacy choices.

Depending on your location, legal requirements, application configuration, and Google’s systems, you may be shown:

  • a consent request;
  • an advertising privacy notice;
  • a privacy-options form;
  • controls for personalized advertising;
  • controls for advertising providers or purposes;
  • a message relating to data processing under regional privacy laws.

In the European Economic Area, the United Kingdom, Switzerland, and other applicable regions, advertising may be delayed until the required consent or privacy status has been determined.

Your available options may include:

  • accepting personalized advertising;
  • rejecting personalized advertising;
  • selecting specific purposes or providers;
  • requesting non-personalized or limited advertisements;
  • reopening privacy options;
  • withdrawing previously provided consent.

Even where personalized advertising is rejected, Google and other providers may still process limited information necessary to:

  • deliver contextual or non-personalized advertisements;
  • measure aggregate performance;
  • maintain security;
  • prevent fraud and invalid traffic;
  • comply with legal obligations;
  • enforce frequency limits;
  • perform essential technical operations.

Withdrawing consent does not affect the lawfulness of processing that occurred before withdrawal.

Consent settings may be stored locally or processed by Google or its consent-management systems.

The availability and appearance of consent controls may change because of:

  • your jurisdiction;
  • Google configuration;
  • regulatory changes;
  • application updates;
  • third-party service changes.

9. Remove Ads Purchase

BioRhythm may offer a one-time purchase identified as Remove Ads or a substantially similar name.

The purchase is intended to remove advertisements from the application for the Google Play account that owns the entitlement, subject to platform availability and successful verification.

The purchase is:

  • a one-time in-app product;
  • not intended to be a subscription;
  • not intended to be consumable;
  • processed through Google Play Billing.

Google Play may process:

  • your Google account information;
  • billing profile information;
  • payment method information;
  • payment authorization information;
  • order number;
  • transaction identifier;
  • purchase token;
  • product identifier;
  • price;
  • currency;
  • tax information;
  • country or region;
  • purchase status;
  • pending-payment status;
  • cancellation information;
  • refund information;
  • chargeback information;
  • fraud-prevention and security information;
  • device and account signals.

We do not receive or store your complete payment-card number or full payment credentials.

BioRhythm may receive limited purchase information necessary to:

  • initiate the purchase;
  • determine whether the product is owned;
  • acknowledge a completed purchase;
  • avoid granting entitlement for an incomplete or pending purchase;
  • restore the purchase;
  • respond to cancellation or refund status;
  • remove or restore advertisements;
  • prevent misuse.

Purchase verification is performed using client-side interaction with Google Play.

No server-side purchase-verification system operated by us is currently used.

Because entitlement verification is client-side, we cannot guarantee that modified, unofficial, rooted, compromised, or pirated versions of the application will correctly enforce purchase status.

Google Play remains responsible for payment processing under its own terms and privacy policies.

10. Purchase Restoration, Refunds, and Revocation

BioRhythm may ask Google Play to refresh or restore the ownership status of the Remove Ads purchase:

  • when the application starts;
  • when it returns to the foreground;
  • when Google Play reconnects;
  • when you manually request restoration;
  • after reinstallation;
  • after an application-data reset;
  • when otherwise reasonably necessary.

A local indicator that advertisements were removed is not necessarily conclusive proof of ongoing purchase ownership.

Purchase access may be refused, suspended, or removed where:

  • Google Play does not report ownership;
  • the transaction remains pending;
  • payment fails;
  • the purchase is cancelled;
  • the purchase is refunded;
  • a chargeback occurs;
  • fraud or unauthorized activity is suspected;
  • the Google account changes;
  • Google Play services are unavailable;
  • applicable law or platform rules require it.

Purchase, tax, accounting, dispute, and refund records may be retained by Google, payment providers, financial institutions, tax authorities, or us for periods required by law.

11. Website Information

When you visit a BioRhythm or MH Softworks webpage, information may be processed by us or by hosting, security, content-delivery, analytics, cookie-management, or infrastructure providers.

This information may include:

  • IP address;
  • date and time of access;
  • requested URL;
  • referring URL;
  • browser type and version;
  • operating system;
  • device type;
  • screen or display information;
  • language;
  • cookie or similar identifiers;
  • server response status;
  • error information;
  • approximate geographic region;
  • interactions with website content;
  • security and anti-abuse signals.

The website may use:

  • essential cookies;
  • local storage;
  • server logs;
  • security technologies;
  • traffic measurement;
  • privacy-friendly or conventional analytics;
  • cookie-consent tools;
  • content-delivery services;
  • spam-prevention services;
  • embedded third-party resources.

Where required by law, non-essential analytics or advertising technologies will be subject to the appropriate consent mechanism.

We may add, remove, or replace website analytics and infrastructure providers in the future.

If a material change substantially affects how personal information is processed, we will update this Privacy Policy as appropriate.

12. Application Analytics and Diagnostics

At the effective date of this Privacy Policy, BioRhythm does not intentionally integrate a proprietary analytics platform, Firebase Analytics, Firebase Crashlytics, Sentry, or a custom crash-reporting backend operated by us.

However:

  • Google Mobile Ads may process application interactions and diagnostics;
  • Google Play and Android may independently process installation, stability, security, purchase, and performance information;
  • application-store or operating-system reports may provide us with aggregated or limited diagnostic information;
  • future versions of BioRhythm may introduce analytics or crash-reporting services.

If future application analytics or crash-reporting services materially change the categories or purposes of information processing, this Privacy Policy and the relevant Google Play disclosures will be updated.

We do not promise that the Service will permanently remain free of every analytics, telemetry, security, or diagnostic technology.

13. Widgets

BioRhythm may provide Android home-screen widgets.

Widgets may display locally calculated or locally stored information, including biorhythm information derived from the date of birth stored on the device.

Depending on your device and launcher:

  • widget content may be visible while the device is unlocked;
  • widget previews may appear in launcher interfaces;
  • widget information may remain visible until refreshed;
  • screenshots or system previews may contain widget information;
  • another person with access to your device may see the displayed information.

You are responsible for deciding whether displaying BioRhythm information on your home screen is appropriate for your privacy needs.

We do not control how third-party launchers, device manufacturers, screenshot tools, accessibility services, or system interfaces display or retain widget content.

14. Notifications

BioRhythm does not currently require general notification access for its main functionality and is not designed to send routine push notifications through a server operated by us.

Future versions may add optional local notifications or reminders.

If notifications are introduced:

  • they may be generated locally on the device;
  • Android may request notification permission;
  • notification content may be visible on the lock screen according to your device settings;
  • you will be able to manage notification permissions through Android settings.

We will update this Privacy Policy if notification functionality materially changes information processing.

15. Information We Do Not Intentionally Collect Through Core Features

The core BioRhythm functionality is not designed to request or collect:

  • precise GPS location;
  • contact lists;
  • call history;
  • SMS or MMS messages;
  • microphone recordings;
  • camera images;
  • photo library contents;
  • files stored elsewhere on your device;
  • health records;
  • genetic information;
  • biometric templates;
  • government identification documents;
  • banking credentials;
  • complete payment-card details;
  • passwords for third-party services.

Third-party SDKs, the operating system, Google Play, Google services, or webpages may process technical information independently as described elsewhere in this Privacy Policy.

16. Purposes of Processing

Information may be processed for the following purposes:

  • providing the Service;
  • performing biorhythm calculations;
  • storing preferences locally;
  • providing widgets;
  • displaying advertisements;
  • managing advertising consent;
  • delivering personalized advertisements where permitted;
  • delivering contextual, limited, or non-personalized advertisements;
  • measuring advertising performance;
  • processing and restoring purchases;
  • maintaining security;
  • preventing fraud and abuse;
  • diagnosing technical problems;
  • responding to support requests;
  • improving reliability and usability;
  • maintaining business and legal records;
  • enforcing applicable terms;
  • protecting our rights, property, users, and the public;
  • complying with law;
  • responding to valid legal requests;
  • establishing, exercising, or defending legal claims;
  • carrying out a business transfer;
  • performing another purpose disclosed when information is collected.

We do not use your locally entered birth date or calculated biorhythm values to make decisions concerning:

  • employment;
  • credit;
  • insurance;
  • housing;
  • education;
  • healthcare;
  • legal eligibility;
  • access to essential services;
  • any other decision producing legal or similarly significant effects.

17. Legal Bases Under European Data-Protection Law

  • maintaining security;
  • preventing fraud;
  • detecting abuse;
  • diagnosing technical failures;
  • protecting legal rights;

19. Sale, Sharing, and Targeted Advertising

We do not sell personal information to third parties in exchange for money.

However, privacy laws in some jurisdictions define “sale,” “sharing,” “targeted advertising,” or “cross-context behavioral advertising” broadly.

Under those definitions, information processed or disclosed through Google AdMob or its advertising partners may be considered:

  • sharing;
  • targeted advertising;
  • cross-context behavioral advertising;
  • or, in some circumstances, a sale.

Where required by applicable law, consent, opt-out, restricted-processing, or privacy-choice mechanisms may be provided through:

  • Google UMP;
  • application privacy controls;
  • Google advertising settings;
  • Android privacy settings;
  • other legally required mechanisms.

We do not knowingly sell personal information belonging to children.

We do not offer a financial incentive in exchange for personal information.

20. Data Retention

Retention depends on the type of information and the entity controlling it.

20.1 Local application information

Locally stored information is generally retained until:

  • you change or delete it;
  • you clear application data;
  • the operating system removes it;
  • the storage becomes corrupted;
  • you uninstall the application;
  • your device is reset;
  • it is overwritten or otherwise lost.

20.2 Support communications

Support communications may be retained for as long as reasonably necessary to:

  • resolve the request;
  • document the response;
  • detect recurring technical problems;
  • prevent abuse;
  • maintain business records;
  • protect legal rights;
  • comply with law.

20.3 Transaction and legal records

Purchase-related, accounting, tax, complaint, refund, and legal records may be retained for the period required or permitted by applicable law.

20.4 Security information

Security, fraud-prevention, and abuse-related records may be retained as reasonably necessary to:

  • investigate incidents;
  • prevent recurrence;
  • protect users;
  • enforce rights;
  • comply with legal obligations.

20.5 Third-party retention

Google and other independent third parties determine their own retention periods.

We generally cannot delete information controlled exclusively by:

  • Google;
  • payment providers;
  • advertising providers;
  • device manufacturers;
  • operating-system providers;
  • hosting providers acting independently;
  • another third party.

Information may be retained longer where necessary for litigation, regulatory inquiries, fraud prevention, enforcement, or legal compliance.

21. Security

We use reasonable measures appropriate to the nature of the Service and the information reasonably available to us.

These measures may include:

  • local processing;
  • limiting requested permissions;
  • disabling cleartext network traffic;
  • disabling standard application backup;
  • separating test and production advertising identifiers;
  • relying on established platform billing;
  • requiring advertising consent status before appropriate advertising requests;
  • limiting direct collection of user information.

However, no application, device, network, transmission, storage method, or security system is completely secure.

We do not guarantee:

  • absolute security;
  • uninterrupted availability;
  • that data will never be lost;
  • that third parties will never gain unauthorized access;
  • that every operating-system or device vulnerability will be prevented;
  • that an unofficial or modified application will behave correctly.

To the maximum extent permitted by law, we are not responsible for incidents caused by circumstances outside our reasonable control, including:

  • a compromised device;
  • malware;
  • rooted or modified operating systems;
  • insecure passwords;
  • compromised Google accounts;
  • unofficial application copies;
  • third-party backup tools;
  • operating-system vulnerabilities;
  • manufacturer defects;
  • network interception;
  • user error;
  • force majeure events;
  • third-party service failures.

You are responsible for:

  • securing your device;
  • securing your Google account;
  • installing updates;
  • using an official application source;
  • reviewing device permissions;
  • controlling lock-screen and widget visibility;
  • protecting your backups.

22. International Transfers

We are established in the Czech Republic.

Google and other service providers may process information in countries other than your country of residence, including countries outside the European Economic Area.

Those countries may have different privacy laws and may not provide the same level of protection.

Where required, international transfers may rely on:

  • adequacy decisions;
  • standard contractual clauses;
  • approved data-protection frameworks;
  • binding corporate rules;
  • contractual safeguards;
  • statutory exceptions;
  • explicit consent;
  • another lawful transfer mechanism.

Third-party providers are responsible for applying the transfer mechanism relevant to their independent processing.

23. Your Rights

Depending on your jurisdiction, you may have the right to:

  • be informed about processing;
  • request access to personal information;
  • request correction;
  • request deletion;
  • request restriction of processing;
  • object to processing;
  • withdraw consent;
  • request data portability;
  • opt out of targeted advertising;
  • opt out of certain sales or sharing;
  • obtain information about categories of information collected;
  • obtain information about categories of recipients;
  • appeal certain privacy-request decisions;
  • complain to a supervisory authority;
  • receive equal service and not be unlawfully discriminated against.

These rights are subject to:

  • applicable-law thresholds;
  • exceptions;
  • identity-verification requirements;
  • our ability to locate the information;
  • whether we control the information;
  • legal retention duties;
  • the rights of other persons;
  • security and fraud-prevention considerations.

We may refuse, limit, or charge a legally permitted fee for a request where the request is:

  • manifestly unfounded;
  • excessive;
  • repetitive;
  • impossible to verify;
  • technically impossible;
  • disproportionate;
  • outside the scope of applicable law.

Because BioRhythm does not require an account and core information remains local, we may be unable to identify you or associate a request with information held by Google or another third party.

To exercise a right regarding information held exclusively by Google, you may need to:

  • use your Google account privacy settings;
  • use Android privacy settings;
  • use Google advertising controls;
  • contact Google directly.

To submit a request concerning information controlled by us, email:

hello@mhsoftworks.com

Use the subject:

BioRhythm Privacy Request

Your request should identify:

  • that it concerns BioRhythm;
  • the right you wish to exercise;
  • the relevant information or processing;
  • information reasonably necessary to locate any relevant record.

We may request additional information to verify identity, authority, and the validity of the request.

24. European Economic Area

If you are in the European Economic Area, the controller for personal information directly controlled by BioRhythm is:

Marek Hovorka
Sole trader operating under the business name MH Softworks
Identification No. (IČO): 17399408
Stavařská 735
686 05 Uherské Hradiště
Czech Republic
Email: hello@mhsoftworks.com

You may lodge a complaint with the data-protection authority in your country of residence, place of work, or place of the alleged infringement.

The competent Czech supervisory authority is:

Office for Personal Data Protection
Úřad pro ochranu osobních údajů

Google or another provider may act as a separate controller for information processed through its services.

25. United Kingdom

Individuals in the United Kingdom may have rights under the UK GDPR and Data Protection Act 2018.

Where UK law applies, you may complain to the UK Information Commissioner’s Office or exercise applicable rights by contacting us.

International processing by Google and other providers may be governed by their own UK transfer mechanisms and privacy documentation.

26. United States Privacy Notice

Depending on whether a particular state privacy law applies to us and the relevant processing, residents of certain US states may have additional rights.

Categories of personal information potentially processed in connection with the Service include:

  • identifiers;
  • IP addresses;
  • device and advertising identifiers;
  • Internet or electronic activity information;
  • application and advertising interactions;
  • approximate location inferred from IP address;
  • commercial and transaction information;
  • diagnostic and performance information;
  • support communications;
  • advertising inferences.

These categories may be processed for the purposes described in this Privacy Policy and disclosed to the recipient categories described above.

We do not knowingly use sensitive personal information to infer characteristics about users for purposes requiring a separate right to limit such use.

We do not knowingly sell personal information for monetary consideration.

Advertising-related processing may constitute sharing or targeted advertising under some state laws.

Available privacy, consent, device, and Google advertising controls may be used to limit such processing.

27. Children and Age Restrictions

BioRhythm is intended for adults and is listed for an adult audience.

The Service is not directed to children and is not intended for use by persons under 18 years of age.

We do not knowingly request that children provide personal information directly to us.

We do not knowingly design the Service to attract children.

The Service does not include an independent age-verification system and cannot guarantee that a younger person will never download or access it.

Parents and legal guardians are responsible for supervising:

  • application downloads;
  • device use;
  • Google Play settings;
  • family account settings;
  • advertising settings;
  • purchases made by minors.

If you are under 18, do not use the Service without the involvement and permission of a parent or legal guardian.

If you believe that a child has provided personal information directly to us, contact:

hello@mhsoftworks.com

We will review the request and take action where required by applicable law.

The availability of BioRhythm in a generally accessible application store does not mean that it is directed to children.

28. Health and Sensitive Information

BioRhythm is an entertainment and informational application.

It is not:

  • a medical device;
  • a medical service;
  • a healthcare provider;
  • a diagnostic tool;
  • a treatment tool;
  • a psychological assessment;
  • a scientific prediction service;
  • a substitute for professional advice.

Biorhythm theory is not scientifically validated.

Calculated results must not be used to make decisions concerning:

  • health;
  • medication;
  • treatment;
  • physical safety;
  • mental health;
  • pregnancy;
  • driving;
  • employment;
  • finance;
  • legal rights;
  • any other important matter.

A date of birth may constitute personal information, but BioRhythm processes it locally for the requested calculation.

Do not enter medical, financial, legal, or other sensitive information into profile labels, messages, or support communications.

29. Automated Processing

BioRhythm automatically calculates cycle values based on dates entered by the user.

This automatic calculation:

  • provides informational application content;
  • does not create a psychological or medical profile;
  • is not used by us to make decisions about you;
  • does not produce legal or similarly significant effects.

Advertising providers may use automated systems to select, personalize, deliver, measure, and protect advertisements.

Those providers are responsible for their independent automated processing and related disclosures.

30. Application Permissions

BioRhythm directly uses limited Android permissions necessary for functions such as:

  • Internet access;
  • checking network availability;
  • advertising;
  • consent management;
  • Google Play Billing;
  • opening online legal or support pages;
  • operating widgets.

Third-party libraries may contribute additional manifest declarations required for:

  • advertising identifiers;
  • Google Ad Services;
  • billing;
  • application components;
  • security or platform functionality.

BioRhythm does not directly request access to:

  • precise location;
  • contacts;
  • camera;
  • microphone;
  • call history;
  • SMS;
  • external storage;
  • Bluetooth;
  • accessibility services;
  • notification-listener access.

Permissions and declarations may change in future versions as Android and third-party SDK requirements evolve.

You may review application permissions through Android settings.

Disabling required system functionality may prevent some features from working.

31. Third-Party Links and Content

The Service may contain:

  • advertisements;
  • links to websites;
  • links to Google Play;
  • links to privacy documents;
  • links to third-party services;
  • content supplied by advertisers.

We do not control and are not responsible for:

  • third-party content;
  • advertiser claims;
  • third-party availability;
  • third-party security;
  • third-party purchases;
  • third-party privacy practices;
  • information submitted outside services controlled by us.

An advertisement, integration, or link does not constitute our endorsement or guarantee.

Review the privacy policy and terms of each third party before interacting with it.

32. Do Not Track and Similar Signals

The BioRhythm application is not a conventional web browser and does not independently respond to browser-based Do Not Track headers.

Where required and technically supported, consent status, restricted-data-processing settings, opt-out signals, or similar privacy choices may be communicated to participating advertising providers.

We cannot guarantee that every third party will recognize or honor every browser, device, or platform signal.

33. Service Changes

The Service may change over time.

We may:

  • add or remove features;
  • add or replace service providers;
  • change advertising formats;
  • change analytics tools;
  • change purchase systems;
  • add optional notifications;
  • alter storage methods;
  • update permissions;
  • discontinue the Service.

Third-party SDK behavior may also change independently through updates.

Privacy disclosures and Google Play Data safety declarations should be reviewed whenever relevant technologies or data practices change.

34. Changes to This Privacy Policy

We may update this Privacy Policy from time to time.

The updated policy will include a revised Last updated date.

Where required by law, we may:

  • provide additional notice;
  • display an in-application notice;
  • request renewed consent;
  • delay particular processing until consent is obtained.

Unless applicable law requires otherwise, an updated version becomes effective when published.

Continued use of the Service does not constitute consent where express consent is legally required.

You should review this Privacy Policy periodically.

35. Language

This Privacy Policy may be translated into other languages.

The English version is the primary version unless mandatory law requires otherwise.

Translations are provided for convenience.

Where legally permitted, the English version will govern in the event of an inconsistency caused by translation.

This provision does not limit mandatory consumer or privacy rights.

36. No Expansion of Obligations

This Privacy Policy describes applicable practices and legal obligations.

To the maximum extent permitted by law, nothing in this Privacy Policy:

  • creates a fiduciary duty;
  • creates a contractual guarantee of absolute security;
  • requires us to collect information that we do not otherwise collect;
  • requires us to retain information solely for a future access request;
  • makes us responsible for information controlled independently by a third party;
  • guarantees uninterrupted availability;
  • guarantees data recovery;
  • prevents us from changing providers or technologies;
  • creates rights beyond those provided by applicable law or an express agreement.

Nothing in this section excludes or limits a duty or right that cannot lawfully be excluded or limited.
