Marek Hovorka is registered in the Czech Trade Licensing Register and operates the App under the business designation MH Softworks.

MH Softworks is a commercial name and brand designation only. It is not a separate company, corporation, partnership, or other legal entity. Any reference in these Terms to “MH Softworks”, “we”, “us”, “our”, or the “Provider” means Marek Hovorka as the sole trader identified above.

Please read these Terms carefully before using the App.

By downloading, installing, accessing, purchasing through, or otherwise using the App, you confirm that you have read, understood, and agreed to these Terms. If you do not agree to these Terms, do not download, install, access, purchase through, or use the App, and uninstall it from your devices.

Nothing in these Terms excludes, limits, or replaces any right or remedy that cannot lawfully be excluded, limited, or replaced.

1. Definitions and scope

For the purposes of these Terms:

“App” means the Barometer Android application and the functionality, content, updates, and related services described above.

“Consumer” means a natural person acting outside that person’s trade, business, craft, or profession.

“Business User” means a person or entity using or attempting to use the App in connection with a trade, business, profession, organisation, institution, occupation, or commercial activity.

“Device” means the phone, tablet, operating system, pressure sensor, Google account, and other hardware or software environment through which the App is used.

“Output” means any value, calculation, estimate, chart, trend, statistic, label, warning, status, interpretation, conversion, or other information displayed by the App.

These Terms apply to the maximum extent permitted by the law applicable to you.

2. Eligibility

You may use the App only if you are legally capable of entering into a binding agreement under the laws applicable to you.

If you are below the age at which you may independently enter into a binding agreement or make an in-app purchase, you may use the App only with the permission and supervision of your parent or legal guardian.

A parent or legal guardian who permits a minor to use the App is responsible for supervising that use and any purchase made through the minor’s or guardian’s account, to the extent permitted by applicable law.

The App is not specifically directed at children.

You may not use the App where doing so would violate applicable law, sanctions, export restrictions, a court order, a contractual restriction, or another legally binding obligation.

3. Intended purpose of the App

The App is a general informational utility intended for casual, non-critical observation of atmospheric pressure and approximate pressure-derived altitude.

The App is not a certified, calibrated, approved, regulated, professional, scientific, medical, meteorological, aeronautical, navigational, surveying, geodetic, engineering, industrial, emergency, or safety instrument.

The App is not designed, tested, certified, or intended for any use in which an inaccurate, delayed, unavailable, incomplete, or misunderstood value could cause or contribute to:

death or personal injury;

illness or a medical emergency;

property damage;

environmental damage;

navigation error;

aviation or transport risk;

loss of orientation;

unsafe weather exposure;

business interruption;

financial loss;

regulatory non-compliance;

breach of a professional duty;

any other material harm.

The App must not be treated as a substitute for a suitable calibrated instrument, official source, qualified professional, manufacturer-approved system, or legally required equipment.

4. Critical safety warning

Do not use or rely on the App as the sole or primary source of information for:

aviation, flight planning, aircraft operation, altimeter setting, air-traffic procedures, parachuting, paragliding, hang-gliding, ballooning, or drone operation;

maritime navigation, boating, diving, or underwater activity;

road navigation, driving, cycling in traffic, railway operation, or operating machinery;

mountaineering, hiking, climbing, caving, skiing, expedition planning, wilderness travel, or determining whether conditions are safe;

weather forecasting, storm detection, severe-weather warnings, evacuation decisions, or emergency preparation;

surveying, construction, engineering, mapping, geodesy, property-boundary determination, or professional measurement;

medical assessment, diagnosis, treatment, medication, oxygen requirements, altitude sickness, blood pressure, respiratory conditions, or any health-related decision;

emergency response, rescue, dispatch, search-and-rescue operations, public safety, or occupational safety;

legal, insurance, financial, contractual, regulatory, or evidential purposes;

any activity where inaccurate information could cause injury, loss, damage, delay, or legal consequences.

Always verify important information using current official information and an appropriate calibrated and certified instrument.

Do not interact with the App while driving, operating machinery, crossing roads, or performing any activity requiring continuous attention.

In an emergency, contact the appropriate emergency services. The App is not an emergency service and cannot request, dispatch, or replace emergency assistance.

5. Pressure-sensor limitations

Pressure readings displayed by the App originate from the pressure sensor and related software provided by the Device, where such a sensor is available.

Some Devices do not contain a pressure sensor. Other Devices may contain sensors with different accuracy, resolution, calibration, sampling behaviour, temperature compensation, drift, noise, latency, or manufacturer-specific processing.

We do not manufacture, inspect, calibrate, control, or certify your Device or its sensor.

Pressure readings may be inaccurate, delayed, unstable, unavailable, or affected by factors including:

sensor quality and factory calibration;

age, wear, damage, contamination, moisture, or manufacturing variation;

Device temperature or rapid temperature changes;

Device cases, covers, membranes, ports, waterproofing, or blocked openings;

indoor ventilation, air conditioning, fans, heating, lifts, vehicles, tunnels, pressure-controlled spaces, or other local conditions;

Device movement, changes in altitude, weather changes, wind, or pressure gradients;

operating-system behaviour;

background-execution restrictions;

battery-saving settings;

sensor-driver errors;

smoothing and sampling settings;

rounding and unit conversion;

software errors or interruptions;

third-party modifications to the Device or operating system.

A sensor accuracy status displayed or supplied by a Device does not constitute certification of the measurement and does not guarantee that a value is correct.

The App may reject readings outside an expected technical range, but such validation cannot establish that an accepted reading is accurate.

6. Pressure values, statistics, charts, and trends

The App may display current pressure, session minimum, session average, session maximum, session range, charts, and a description of whether pressure appears to be rising, falling, or stable.

These outputs describe only the readings available to the App during the relevant local session. They are not official meteorological observations and must not be interpreted as a weather forecast.

A pressure change can result from weather, movement to a different altitude, indoor pressure conditions, Device handling, sensor drift, temperature, or other causes. The App generally cannot determine which cause produced a change.

A label such as “rising”, “falling”, or “stable” does not predict future weather, storm development, safety, visibility, precipitation, wind, temperature, or any other meteorological condition.

Session statistics and charts may be incomplete, reset, truncated, delayed, or lost. They are not intended to constitute a permanent record, official log, evidential record, or archival service.

Different settings, Devices, sensors, applications, measuring instruments, algorithms, time periods, and physical locations may produce different results.

7. Estimated altitude

Any altitude displayed by the App is a mathematical estimate derived from atmospheric pressure and a reference pressure.

Pressure-derived altitude is inherently sensitive to weather and the selected reference pressure. A change in weather may change the estimated altitude even when the Device has not physically moved. Physical movement and weather-related pressure change may be indistinguishable to the App.

The displayed altitude may differ materially from:

actual elevation;

surveyed elevation;

GNSS or GPS altitude;

map elevation;

aircraft altitude;

barometric altitude from a certified instrument;

another application or Device.

The App’s altitude output is not a geodetic, terrain, navigation, or aviation measurement.

The words “altitude”, “elevation”, “above sea level”, or similar labels describe the type of estimate being presented. They do not represent a guarantee that the displayed value is the true altitude above mean sea level.

8. QNH and calibration

The App may use a default, manually selected, or mathematically derived QNH reference value to estimate altitude.

A QNH value displayed, entered, stored, or derived by the App is not guaranteed to be current, local, meteorologically correct, or suitable for aviation.

The App does not independently verify the user’s physical location, official local pressure, actual altitude, weather conditions, or the accuracy of a value entered by the user.

Known-altitude calibration calculates a reference pressure from the sensor reading and the altitude entered by the user. Calibration may improve consistency under some conditions, but it does not:

certify the Device or App;

correct every sensor error;

guarantee future accuracy;

prevent weather-related drift;

create an official QNH value;

turn the Device into an approved altimeter.

A calibration may become inaccurate as atmospheric conditions change or when the Device moves to another location.

You are solely responsible for the accuracy, lawfulness, suitability, and source of any altitude or QNH value you enter.

Never use QNH or altitude displayed by the App for aircraft altimeter setting, flight operations, air navigation, or any safety-critical purpose.

9. Units and conversions

The App may display pressure in units including hPa, mmHg, and inHg and altitude in metres or feet.

Unit conversion changes the presentation of a value. It does not improve the accuracy of the underlying sensor reading.

Rounding may cause a converted value to differ slightly from another source.

A pressure value displayed in mmHg is atmospheric pressure. It is not a measurement of human blood pressure and must not be interpreted as one.

You are responsible for confirming that you understand the selected unit before using or communicating any displayed value.

10. No medical or professional advice

The App is not a medical device and does not provide medical, diagnostic, therapeutic, meteorological, aviation, navigation, engineering, surveying, legal, financial, insurance, or other professional advice.

The App cannot diagnose, monitor, treat, cure, mitigate, or prevent any disease, injury, disability, or health condition.

Do not use atmospheric pressure or altitude estimates from the App to make decisions concerning medication, respiratory conditions, cardiovascular conditions, headaches, pain, pregnancy, altitude sickness, oxygen requirements, physical exertion, or emergency care.

Always consult an appropriately qualified professional regarding medical, technical, safety-related, legal, financial, or other professional matters.

11. Your responsibilities

You are responsible for:

using the App only for its intended non-critical purpose;

maintaining a compatible and reasonably secure Device;

confirming that the Device has a suitable pressure sensor;

checking for obvious errors or implausible values;

selecting and understanding the correct units;

entering accurate calibration and reference values;

independently verifying all important information;

using appropriate official sources and calibrated equipment;

maintaining situational awareness;

following applicable laws, regulations, instructions, and professional standards;

keeping the App and operating system reasonably up to date;

protecting your Device and Google account from unauthorised access;

maintaining any backups you consider necessary;

paying any Device, data, internet, platform, or other third-party charges;

stopping use immediately if the App appears inaccurate, defective, distracting, or unsafe.

Your decision to use or rely on any App Output is made at your own discretion and risk, subject to liability and rights that cannot legally be excluded.

12. Licence to use the App

Subject to your compliance with these Terms, we grant you a limited, personal, non-exclusive, non-transferable, non-sublicensable, and revocable licence to install and use an authorised copy of the App on compatible Devices that you own or lawfully control.

The licence is granted solely for personal and non-commercial use unless we expressly agree otherwise in writing.

The App is licensed, not sold.

You do not acquire ownership of the App, source code, object code, algorithms, designs, calculations, databases, content, visual elements, trademarks, or underlying technology.

Your use of a copy obtained through Google Play is also subject to Google Play’s applicable terms, technical restrictions, and account requirements.

All rights not expressly granted are reserved.

13. Prohibited conduct

To the maximum extent permitted by applicable law, you must not directly or indirectly:

copy, reproduce, distribute, publish, sell, lease, sublicense, rent, or commercially exploit the App or a substantial part of it;

reverse engineer, decompile, disassemble, decode, translate, modify, or attempt to derive source code, algorithms, non-public interfaces, or technical structure, except to the limited extent expressly permitted by mandatory law;

assist, encourage, or enable another person to engage in prohibited conduct.

Restrictions on reverse engineering and interoperability apply only to the extent permitted by mandatory law.

14. Intellectual property

The App and associated materials are protected by copyright, trademark, database, trade-secret, and other intellectual-property laws.

Except for third-party material, all rights, title, and interest in the App belong to Marek Hovorka or the relevant licensors.

Protected materials may include:

source code and object code;

algorithms and calculation implementations;

designs and layouts;

user interfaces;

icons and graphics;

animations;

texts and translations;

charts and visualisations;

data structures;

product names;

brand elements;

documentation;

promotional materials.

No implied licence is granted.

The names Barometer and MH Softworks and associated brand identifiers may not be used in a way that falsely suggests sponsorship, endorsement, affiliation, partnership, or permission.

You may ordinarily create screenshots for lawful personal, informational, review, journalistic, or educational purposes, provided that the use is not misleading, infringing, defamatory, or presented as official.

15. Third-party and open-source components

The App may contain or depend on third-party or open-source software.

Third-party and open-source components may be governed by their own licences. Where an applicable third-party or open-source licence grants rights that conflict with a restriction in these Terms, that licence controls solely with respect to the relevant component.

Third-party names and trademarks belong to their respective owners.

The inclusion of third-party technology does not imply sponsorship or endorsement.

16. Advertisements

The free version of the App may display advertisements supplied by third-party advertising providers, including Google AdMob.

Advertisements may include banners, app-open advertisements, rewarded advertisements, or other formats permitted by the relevant platform and applicable law.

Subject to applicable consent requirements and privacy choices, third parties may select, deliver, limit, measure, secure, or personalise advertising in accordance with their own terms and privacy practices.

Unless expressly stated otherwise:

we do not endorse any advertiser;

we do not endorse an advertised product, service, statement, or claim;

we are not a party to a transaction between you and an advertiser;

we do not control third-party websites, products, prices, availability, security, delivery, or representations;

we are not responsible for an advertiser’s conduct.

Your interaction with an advertisement, external website, advertiser, product, or service is at your own discretion and risk.

You should independently assess advertisements before making a purchase, installing software, following advice, or providing personal information.

The number, location, timing, frequency, availability, and format of advertisements may change.

Temporary absence of advertisements does not create a right to permanently ad-free use.

A privacy choice concerning personalised advertising does not necessarily prevent all advertising. Non-personalised or limited advertising may still be displayed where permitted.

Advertising does not intentionally alter the pressure value supplied by the Device sensor or the App’s mathematical altitude formula.

17. Optional rewarded-advertising benefits

The App may offer an optional benefit in exchange for completing an eligible advertising interaction, such as a temporary period of 30 minutes without advertisements.

Availability of rewarded advertising is not guaranteed. It may depend on:

internet connectivity;

geographic location;

advertising inventory;

privacy and consent status;

third-party eligibility rules;

Device configuration;

account status;

technical availability;

the advertising provider’s decision.

A benefit is granted only after the App receives the required completion or reward confirmation.

Closing, skipping, interrupting, or failing to complete an advertisement may result in no benefit being granted.

Temporary ad-free time:

has no cash value;

is not a purchase;

is not transferable;

cannot be exchanged, sold, or refunded;

expires automatically;

may be affected by clearing App data, uninstalling the App, replacing the Device, changing system time, software errors, or other technical events.

We may modify or discontinue an optional rewarded-advertising benefit where reasonably necessary, subject to applicable law.

18. One-time advertising-removal purchase

The App may offer a one-time, non-consumable in-app product identified as “remove_ads”.

This product is not a subscription.

While a valid entitlement is recognised, the product removes advertisements requested or displayed by the App. It does not provide ownership of the App, professional functionality, certified measurements, a service-level guarantee, lifetime technical support, or rights to future products or separately offered premium features.

The entitlement ordinarily depends on:

a valid and completed purchase;

continued ownership of the purchase by the relevant Google account;

use of the same App package and a compatible version;

availability of Google Play Billing and purchase verification;

compliance with these Terms;

the App remaining available and technically supported.

The purchase is not transferable between Google accounts, unrelated applications, different platforms, or unauthorised copies. Availability through family-sharing mechanisms is not guaranteed.

Restoration may require the original purchasing account, an internet connection, Google Play services, and successful verification.

If a purchase is refunded, cancelled, charged back, reversed, revoked, found fraudulent, or otherwise no longer recognised as owned, the advertising-removal entitlement may be withdrawn.

A delay in verification may temporarily affect recognition of the entitlement.

The expression “permanent” or “permanently remove ads”, where used in a purchase description, means that the purchase is non-subscription and does not have a scheduled recurring expiry while the valid entitlement and the supported App continue to exist. It does not guarantee that the App or any service will be operated forever.

Nothing in this section limits any mandatory right or remedy relating to paid digital content.

19. Prices, billing, withdrawal, and refunds

The price, currency, taxes, payment method, and purchase conditions applicable to an in-app purchase are those displayed through the authorised purchase interface at the time of purchase.

Purchases made through Google Play are processed through Google Play or its designated payment provider. Google Play’s billing, authentication, payment, withdrawal, and refund conditions may apply in addition to these Terms.

You are responsible for:

reviewing the displayed price before confirming a purchase;

using a payment method you are authorised to use;

protecting your Google account;

configuring purchase authentication and parental controls;

checking that the correct account is active;

retaining the relevant order information.

Except where a refund or other remedy is required by applicable law or platform rules, completed digital purchases are final and non-refundable.

Where permitted by law, by requesting immediate activation of digital content, you request that supply begin immediately. Any statutory right of withdrawal is lost only where all legally required conditions, including prior express consent and acknowledgement, have been validly satisfied.

Consumers may retain statutory remedies where digital content is defective, unavailable, not supplied, or not in conformity with the contract.

Refund requests for Google Play purchases should ordinarily be submitted through Google Play’s refund process. You may also contact us where Google Play directs you to the developer or where applicable law requires assistance from us.

If a refund is granted, access to the refunded entitlement may end.

20. Updates and compatibility

We may release updates, upgrades, corrections, security patches, design changes, and new versions.

An update may:

add, modify, replace, or remove functionality;

change appearance or navigation;

modify calculations or their presentation;

change compatibility requirements;

change advertising implementation;

change third-party integrations;

correct defects or vulnerabilities;

be required for continued use.

Valid reasons for modifications may include security, legal compliance, platform requirements, changes to Android, Device compatibility, third-party service changes, technical feasibility, accessibility, performance, localisation, usability, fraud prevention, or important operational requirements.

We do not guarantee compatibility with every Device, operating-system version, custom ROM, accessibility service, screen configuration, sensor, Google Play version, or third-party application.

Older versions may become unsupported or cease to function.

Where mandatory law requires updates necessary to maintain the conformity of paid digital content, we will provide them for the legally required period and under the legally required conditions.

Failure to install an available update may affect functionality, security, compatibility, advertising removal, or purchase verification.

To the extent permitted by law, we are not responsible for a lack of conformity caused solely by failure to install an update, provided that the legally required information and instructions were supplied.

Where mandatory consumer law regulates modifications that negatively affect access to paid digital content, the relevant notice, continued-access, termination, or other statutory rights remain available.

21. Availability, support, and discontinuation

We aim to keep the App functional, but uninterrupted, error-free, or permanent availability is not guaranteed.

The App or any feature may be affected by:

maintenance;

defects;

security incidents;

Device or operating-system changes;

internet or infrastructure failures;

third-party outages;

Google Play decisions;

advertising-provider decisions;

legal or regulatory requirements;

events outside our reasonable control.

To the maximum extent permitted by law, we may modify, restrict, suspend, replace, or discontinue all or part of the App where reasonably necessary.

Possible reasons include security, legal requirements, technical infeasibility, incompatibility, low usage, excessive cost, third-party service discontinuation, platform removal, or business restructuring.

No purchase creates an obligation to operate, update, or distribute the App indefinitely.

Where discontinuation or modification affects paid digital content, we will respect any remedy required by mandatory consumer law.

Support is provided on a reasonable-efforts basis. No guaranteed response time, resolution time, service level, or continued support period is promised unless required by law or expressly agreed in writing.

22. Privacy

continued provision is no longer technically or commercially feasible.

Where reasonably possible and legally appropriate, we may provide notice or an opportunity to remedy a breach before termination.

Immediate action may be taken in cases involving fraud, security threats, unlawful conduct, serious abuse, or urgent legal requirements.

Termination does not affect rights or obligations that arose before termination.

If termination affects paid digital content, mandatory statutory remedies remain available.

Provisions that by their nature should survive termination continue to apply, including provisions concerning intellectual property, feedback, disclaimers, liability, responsibility for claims, disputes, and governing law.

31. Changes to these Terms

We may update these Terms where reasonably necessary, including to:

reflect changes to the App;

introduce, modify, or discontinue functionality;

comply with legal, regulatory, security, or platform requirements;

address misuse, fraud, vulnerabilities, or harmful conduct;

clarify existing provisions;

reflect changes in third-party services or our business.

The current version will be published with an updated “Last updated” date.

Changes generally apply prospectively.

Where required by applicable law, we will provide additional notice of a material change and obtain any required consent before the change becomes binding.

We will not use an update to retroactively remove mandatory rights already acquired.

If you do not agree to an updated version, you must stop using and uninstall the App, subject to any statutory rights concerning paid digital content.

32. Events outside our reasonable control

To the maximum extent permitted by law, we are not responsible for delay, interruption, or failure caused by an event outside our reasonable control.

Such events may include:

natural disasters;

fire or flood;

war, terrorism, or civil unrest;

epidemics;

labour disputes;

utility failures;

telecommunications or internet failures;

cyberattacks;

app-store actions;

government measures;

legal changes;

infrastructure failures;

Device-manufacturer changes;

third-party provider failures.

This section does not remove any right that cannot legally be excluded.

33. Governing law

These Terms and your relationship with us are governed by the laws of the Czech Republic, excluding conflict-of-law rules, unless mandatory law requires otherwise.

If you are a Consumer habitually resident in another country, this choice of law does not deprive you of protection granted by mandatory provisions of the law of your country of habitual residence.

The United Nations Convention on Contracts for the International Sale of Goods does not apply.

34. Disputes and jurisdiction

Before starting formal proceedings, you are encouraged to contact us at hello@mhsoftworks.com and provide a reasonable description of the dispute so that an informal resolution may be attempted.

If you are a Business User, the courts having territorial jurisdiction over our business address in the Czech Republic will have exclusive jurisdiction unless mandatory law provides otherwise.

If you are a Consumer, you may bring a claim before any court having jurisdiction under applicable consumer and procedural law.

Nothing in these Terms restricts a Consumer’s right to use the courts of the Consumer’s country of residence where that right is provided by mandatory law.

We do not require Consumers to resolve disputes through private arbitration.

35. Alternative dispute resolution for Consumers

If a consumer dispute arising from a purchase or provision of services cannot be resolved directly between us, the Consumer may be entitled to submit the dispute to the competent alternative dispute resolution body:

Czech Trade Inspection Authority
Central Inspectorate – ADR Department
Gorazdova 1969/24
120 00 Prague 2
Czech Republic

Email: adr@coi.gov.cz
Website: https://coi.gov.cz/informace-o-adr/

The applicable eligibility rules, time limits, competence, language requirements, and procedure are determined by law and by the rules of the Czech Trade Inspection Authority.

The European Online Dispute Resolution platform was discontinued and Regulation (EU) No 524/2013 was repealed with effect from July 20, 2025. It is therefore not presented as an available dispute-submission channel.

36. Google Play

Where the App is downloaded through Google Play:

these Terms are between you and Marek Hovorka, not between you and Google;

Google is not responsible for the App or its content except to the extent required by Google’s own terms or applicable law;

your use of Google Play remains subject to Google’s terms;

payments, purchase authentication, withdrawal acknowledgements, and refunds may be administered through Google Play;

Google may suspend, remove, or restrict the App independently of us;

Google may enforce provisions that expressly grant it rights where permitted by applicable law.

Nothing in this section creates obligations for Google beyond obligations arising under Google’s own terms or applicable law.

37. Electronic communications

Notices, disclosures, and communications relating to the App may be provided electronically, including through:

an in-app notice;

an app-store listing;

an update notice;

our website;

an email address supplied by you;

another reasonable electronic method.

Electronic communications satisfy a requirement that communication be in writing where permitted by law.

Where mandatory law requires communication on a durable medium or express consent, the legally required method will apply.

You are responsible for ensuring that contact information supplied by you is accurate and current.

38. Assignment and transfer

You may not assign, transfer, sublicense, or delegate your rights or obligations under these Terms without our prior written consent.

We may transfer or assign our rights and obligations in connection with:

a sale or transfer of the App;

a merger or acquisition;

a restructuring;

a transfer of business assets;

a succession of the business;

a similar transaction.

Any transfer remains subject to applicable law and will not unlawfully reduce mandatory consumer rights.

Where required by law, affected users will be informed.

39. No waiver

A failure or delay in enforcing a provision of these Terms does not constitute a waiver of that provision or any other right.

A waiver is effective only when made expressly and, where required, in writing.

A waiver relating to one breach does not constitute a waiver relating to another breach.

40. Severability

If a provision of these Terms is found to be invalid, unlawful, or unenforceable, it will be interpreted or limited to the minimum extent necessary to make it valid and enforceable where legally possible.

If it cannot be made enforceable, it will be severed.

The remaining provisions will continue in effect.

For consumer contracts, this section will not be interpreted as permitting an invalid or unfair provision to be replaced with a provision that disadvantages the Consumer contrary to mandatory law.

41. Entire agreement and order of precedence

These Terms, the Barometer Privacy Policy, applicable point-of-sale information, and any specific purchase conditions expressly accepted by you constitute the agreement concerning the App.

They replace previous agreements concerning the same subject matter, except for rights, public statements, representations, and obligations that cannot legally be excluded.

In the event of a conflict:

mandatory law prevails;

specific purchase terms expressly accepted at the point of sale prevail regarding that purchase;

app-store terms govern your separate relationship with the app-store provider;

these Terms govern your relationship with us concerning the App;

the Privacy Policy governs the description of personal-data processing.

Nothing in this section excludes liability for fraud or fraudulent misrepresentation where such liability cannot legally be excluded.

42. Interpretation

Headings are included for convenience and do not limit the meaning of a provision.

Words such as “including”, “includes”, and “for example” are illustrative and do not limit the words preceding them.

A reference to the singular includes the plural where appropriate, and vice versa.

A reference to a person may include a natural person or legal entity where appropriate.

A reference to written permission means permission provided by Marek Hovorka or a person expressly authorised to act on his behalf.

If a provision is qualified by “to the maximum extent permitted by law” or similar wording, the provision applies only within the legally enforceable limit.

43. Language

These Terms may be made available in languages other than English for convenience.

Unless mandatory law requires otherwise, the English version is the reference version used to interpret the Terms.

A translation does not reduce any right granted by applicable law.

Where a translated version conflicts with the English version, the English version prevails only to the extent permitted by law.

44. Contact information
