Terms of Use

summit.day · Last updated: 23 October 2026

These terms apply when you use summit.day (“the service”), operated by Jost Kobusch and Michal Frankowski (“we”). By using the service you agree to them. How we handle your data is described in our Privacy Policy.

1. The service

summit.day lets you view and plan routes on a map and, if you connect an account such as Garmin Connect, Strava or Zepp, view your own activities from it. The service is provided as is and may change or be unavailable at times.

2. Your account and data

3. Acceptable use

4. Safety

Mountain travel is dangerous. Routes, elevation, weather and other information shown in the service can be wrong, incomplete or out of date. Use your own judgement and proper equipment. The service is not a safety or emergency system and must not be relied on to protect life or to call for help.

5. Third-party services and data

Connected services (for example Garmin, Strava, Zepp, WHOOP) have their own terms, which you remain bound by. Their names and logos belong to their owners. We are not endorsed by, or affiliated with, them unless stated.

6. Liability

To the extent the law allows, the service is provided without warranties, and we are not liable for any loss or damage arising from your use of it, including loss of data and any consequences of relying on information shown. Nothing here limits liability that cannot be limited by law. These terms also protect the providers of connected services to the same extent as they protect us.

7. Changes and ending

We may update these terms or end or limit access to the service. If we make a material change we will update the date above. You may stop using the service at any time.
