Terms of Service – Weather Lab

Effective date: 10 October 2026

These Terms of Service (“Terms”) govern your use of the Weather Lab mobile app, its home-screen widgets, notifications, and related online services (together, the “Service”), provided by Hectopixel (“we”, “us”, “our”). By downloading, installing, or using the Service, you agree to these Terms. If you do not agree, please do not use the Service.

Our Privacy Policy explains how we collect and process personal data and forms part of these Terms.

1. The Service

Weather Lab shows weather forecasts, radar and satellite imagery, maps, weather warnings, station observations, and related information, and lets you customize how this information is displayed, including by creating your own sections, widgets, and templates. The Service is provided free of charge and is supported by advertising. An optional paid subscription removes advertising (see “Ad-Free Subscription”).

We may add, change, limit, or remove features of the Service, including weather models, data sources, and map layers, at any time and without prior notice.

2. Weather Information – Important Safety Notice

Weather forecasts are predictions, not facts. They are produced by numerical weather models and third-party data providers and are by their nature uncertain. Forecasts, radar and satellite imagery, nowcasts, warnings, observations, and any other information in the Service may be inaccurate, incomplete, delayed, out of date, or unavailable, and may differ significantly from the weather that actually occurs.

• The Service is provided for general information purposes only. It is not a substitute for official forecasts and warnings issued by your national meteorological service or civil protection authorities, and it is not intended for use in situations where an error or outage could lead to death, personal injury, or damage to property or the environment.
• Do not rely on the Service as your only or primary source of information for decisions that affect safety, health, or property – for example aviation, sailing, boating, mountaineering, outdoor events, agriculture, construction, or protection against severe weather, flooding, or other hazards.
• Weather warnings shown in the Service are relayed from third-party issuers. We do not create, review, or verify them, and we cannot guarantee that every warning in force is shown, that it is shown in time, or that its translation or display is correct. Absence of a warning in the app does not mean that no danger exists.
• Notifications and widgets are refreshed on a best-effort basis. Your device’s operating system decides when background updates run and may delay or prevent them (for example in battery-saving modes), so the information shown may be out of date.

Always follow instructions from official authorities and use your own judgment. You use the weather information in the Service at your own risk.

3. Availability

We aim to keep the Service running, but we do not guarantee that it will be available at all times or free of errors. The Service depends on our servers, on third-party data providers, and on network connections, any of which may fail. The Service may be interrupted, slowed down, or unavailable – in whole or in part – due to maintenance, updates, technical failures, outages of third-party providers, attacks, or events beyond our control. We are not obliged to provide any particular level of availability, support, or updates, and we may suspend or discontinue the Service, or any part of it, at any time.

4. Your Account

The app automatically creates an anonymous account for each installation. You may sign in with Apple, Google, or your email address to keep your content across devices. You are responsible for keeping access to your device and to your sign-in method secure, and for all activity under your account. You can delete your account at any time in the app under Account → Delete account.

We may suspend or delete an account, or remove content, if we reasonably believe it is used in breach of these Terms, in breach of the law, or in a way that harms the Service or other users.

5. Content You Create and Share

The Service lets you create custom sections, widget designs, and templates (“User Content”). You keep any rights you have in your User Content. To operate the Service, you grant us a worldwide, non-exclusive, royalty-free license to store, copy, process, and display your User Content for the purpose of providing the Service to you – for example to back it up and restore it on your other devices.

If you share User Content via a link or publish it to the in-app gallery, you additionally grant us and other users of the Service a worldwide, non-exclusive, royalty-free license to use, display, copy, and modify that content within the Service. Published content may remain available after you delete your account, as described in the Privacy Policy. We may review, decline, or remove submitted or published content at our discretion, and we do not guarantee that any content will be accepted or remain published.

You are responsible for your User Content and must have the necessary rights to it. User Content must not:

• be unlawful, offensive, defamatory, harassing, or infringe the rights of others, including intellectual property and privacy rights;
• be misleading in a way that could endanger others, for example by imitating official weather warnings;
• contain code that attempts to bypass the app’s sandbox, collect data about other users, overload or attack the Service, or otherwise interfere with its operation.

Content created by other users is not reviewed or endorsed by us, and we are not responsible for it. Templates published by other users may display weather data incorrectly or incompletely.

6. Acceptable Use

You agree not to:

• use the Service in breach of any applicable law;
• access our servers or data other than through the app, or use automated means (such as scrapers or bots) to retrieve data from the Service;
• resell, redistribute, or commercially exploit weather data, radar imagery, or other content obtained through the Service;
• reverse engineer, decompile, or tamper with the app or our servers, except to the extent such restriction is not permitted by law;
• interfere with or disrupt the Service, its security, or its advertising, or attempt to gain unauthorized access to any part of it.

7. Advertising

The free version of the Service displays advertisements provided by third parties, such as Google AdMob. We are not responsible for the content of advertisements or for products and services offered in them. Your choices regarding personalized advertising are described in the Privacy Policy.

8. Ad-Free Subscription

You may purchase an optional subscription that removes advertising from the Service on your devices. Purchases are processed by the Apple App Store or Google Play, subject to their terms. The subscription renews automatically for the same period at the then-current price until you cancel it. You can manage or cancel the subscription in your App Store or Google Play account settings; cancellation takes effect at the end of the current billing period. Deleting the app or your account does not cancel the subscription. Refunds are handled by Apple or Google under their policies, except where mandatory law provides otherwise.

The subscription only removes advertising. It does not change the nature of the Service or the disclaimers in these Terms, and it does not include any guarantee of accuracy or availability.

9. Third-Party Data and Services

The Service uses data and services provided by third parties, including weather models and observations from national meteorological services and Open-Meteo, radar and satellite data, weather warnings from official issuers, map data from OpenFreeMap and OpenStreetMap contributors, place-name lookup services, and sign-in services from Apple and Google. These third parties are not responsible for the Service, and we are not responsible for their data or services. Their data is provided under their own licenses and terms, and attributions are shown in the app where required.

10. Intellectual Property

The app, its design, built-in templates, and the Weather Lab name and logo belong to us or our licensors. Subject to these Terms, we grant you a personal, non-exclusive, non-transferable, revocable license to install and use the app on devices that you own or control, for your personal, non-commercial use.

11. Disclaimer of Warranties

To the maximum extent permitted by applicable law, the Service and all information in it are provided “as is” and “as available”, without warranties of any kind, whether express or implied, including any warranties of accuracy, reliability, timeliness, completeness, availability, merchantability, fitness for a particular purpose, and non-infringement. We do not warrant that the Service will meet your requirements, that it will be uninterrupted, secure, or error-free, or that any data, forecast, or warning will be correct.

12. Limitation of Liability

To the maximum extent permitted by applicable law, Hectopixel shall not be liable for any damages, losses, costs, or expenses of any kind arising out of or in connection with the Service, including in particular:

• any decision made or action taken or not taken in reliance on forecasts, warnings, radar, observations, or any other information provided by the Service;
• inaccurate, incomplete, delayed, or missing weather information or warnings;
• any unavailability, interruption, or malfunction of the Service, its servers, widgets, or notifications, or of third-party data providers;
• loss of data or User Content;
• indirect, incidental, special, or consequential damages, lost profits, or loss of business opportunity.

Where our liability cannot be excluded but may be limited, our total liability arising out of or in connection with the Service shall not exceed the amount you paid us for the Service in the twelve months before the event giving rise to the liability, or EUR 10 if you paid nothing.

Nothing in these Terms excludes or limits liability that cannot be excluded or limited under applicable law, such as liability for damage caused intentionally or through gross negligence, or for death or personal injury caused by our negligence, and nothing in these Terms affects your statutory rights as a consumer.

13. Indemnity

To the extent permitted by law, you agree to indemnify and hold harmless Hectopixel from any claims by third parties arising out of your User Content or your breach of these Terms.

14. Apple App Store Terms

If you downloaded the app from the Apple App Store, these Terms are concluded between you and Hectopixel only, not with Apple, and Apple is not responsible for the app or its content. Apple has no obligation to provide maintenance or support for the app. To the maximum extent permitted by law, Apple has no warranty obligation with respect to the app; if the app fails to conform to any applicable warranty, you may notify Apple, and Apple will refund the purchase price, if any. Apple is not responsible for addressing any claims by you or any third party relating to the app, including product liability claims, claims that the app fails to conform to legal or regulatory requirements, consumer protection claims, or intellectual property infringement claims. Apple and its subsidiaries are third-party beneficiaries of these Terms and may enforce them against you. Your use of the app must also comply with the App Store Terms of Service.

15. Termination

You may stop using the Service at any time by deleting the app and, if you wish, your account. We may suspend or end your access to the Service at any time if you breach these Terms or if we discontinue the Service. Sections 2, 5 (for published content), and 9 to 13 continue to apply after termination.

16. Changes to These Terms

We may update these Terms from time to time, for example when we add new features or when the law changes. We will post the updated Terms on this page and update the effective date above. If the changes are significant, we will make reasonable efforts to inform you, for example in the app. By continuing to use the Service after the changes take effect, you accept the updated Terms.

17. Governing Law

These Terms are governed by the laws of the Czech Republic, excluding its conflict-of-law rules. If you are a consumer, this choice of law does not deprive you of the protection of the mandatory provisions of the law of the country where you have your habitual residence, and you may bring proceedings in the courts of that country. If any provision of these Terms is found invalid or unenforceable, the remaining provisions remain in full force.
