Crisp Widget for Weather
Terms of Use

Effective October 12, 2026

This English version is provided for convenience. The Japanese version is the original.

1. Scope

1.1 These Terms set out the conditions for using the Android app "Crisp Widget for Weather" (the "App") provided by d mark ("we", "us").
1.2 By using the App, you agree to these Terms.
1.3 Google Play's terms of service also apply to downloading the App.

2. The App

2.1 The App is a free tool that shows the chance of precipitation, temperature and air quality (AQI) forecast for a chosen location as a home-screen widget. There are no in-app purchases, no ads and no account.
2.2 Forecast data comes from Open-Meteo (https://open-meteo.com/) and is provided under the CC BY 4.0 license (Weather and air quality data by Open-Meteo.com). Air quality data contains modified Copernicus Atmosphere Monitoring Service (CAMS) information.
2.3 The App connects to the internet to get forecasts. You are responsible for any data charges.
2.4 Widget updates depend on your connection, Android's battery-saving features, your device settings and manufacturer-specific features, and may be delayed or stop.

3. Nature of forecasts

3.1 Forecasts are predictions provided by a third party and may differ from actual weather. We do not warrant that they are accurate, complete or up to date.
3.2 Do not rely on the App's forecasts for decisions that affect the safety of life, health or property (such as mountaineering, activities on the sea or rivers, or disaster preparation). Check official information from your national weather service.

4. External sites and services

External sites you can open from the App (such as meteoblue and Open-Meteo) and the external service that provides forecast data are run by their own operators under their own terms. We are not responsible for their content or for whether they continue to be available.

5. Prohibited conduct

You must not: break any law; modify, decompile or reverse-engineer the App (except as permitted by law); place an excessive load on external services through the App; redistribute or sell the App in whole or in part; or infringe our or anyone else's rights.

6. Intellectual property

Copyright and other rights in the App belong to us or the rightful owners. Third-party materials in the App, such as fonts, and forecast data are subject to their own licenses.

7. No warranty

We do not warrant that the App fits your particular purpose, that it is free of bugs, or that it works on every device. The App may become unable to show forecasts if an external service stops or changes.

8. Limitation of liability

8.1 If you suffer damage due to our breach of contract or tort, except in cases of our intent or gross negligence, we are liable only for direct and ordinary damage actually incurred.
8.2 If any part of these Terms is held invalid under applicable law, the rest remains in effect. Nothing in these Terms limits rights you have as a consumer under the mandatory laws of your country of residence.

9. Changes to and discontinuation of the App

We may change the App or stop distributing it. If the forecast data provider stops or changes its service, installed copies of the App may no longer be able to show forecasts.

10. Changes to these Terms

We may change these Terms when needed, for example due to changes in law or new features. We will announce the new Terms and their effective date on the support site before they take effect.

11. Governing law and jurisdiction

These Terms are governed by the laws of Japan. The district court with jurisdiction over our location has exclusive jurisdiction in the first instance, without prejudice to the mandatory consumer rights of your country of residence.
