Privacy

What you agree to (version 2026-11-05)

  • This is an experiment. Atsusa is not a medical device and does not give medical advice.
  • The temperature on your watch is an estimate, not a measurement. Always listen to your body.
  • The watch app sends anonymous usage events (no location, no heart rate).
  • If you upload a run, we store heart rate, the Atsusa estimate and weather.
  • Your GPS route is removed unless you choose to share the full file.
  • You can delete your data any time at atsusa.app/garmin-tester/delete.

What we store

Watch usage events: anonymous (app opened, run started/stopped, alert levels reached). No location and no heart rate. The device ID is scrambled before we store it. Kept for 12 months.

Runs you upload: heart rate, the Atsusa estimate, weather, distance and speed. GPS position and altitude are removed in your browser before upload. Kept until you delete them.

Full run file: only if you untick "Remove my GPS route". Stored privately.

Name and email: optional, only for updates.

No tracking cookies and no analytics scripts on these pages. Files are stored privately and only opened through short-lived links.

Delete your data

Ask any time with your tester code or email: delete my data.
