What we store
Your email address (to sign you in), the name you choose, the groups you join, the daily numbers you log, and the screenshots you attach as proof. Screenshots can contain health data. We store them so the people in your group can see them; we do not read them for any other purpose.
Who can see it
Only members of the group a challenge belongs to. Your road position, standings, entries and screenshots are never public. Group owners and admins can void an entry after a flag; nothing is deleted.
We send sign-in links, a nightly bulletin at 8 pm in your group's timezone while a race is on, and a final email when it ends. Turn the bulletin off any time on your profile page.
Where it lives
Data is stored with Supabase (Postgres and object storage) and served from Vercel. Email goes through Resend. Maps are drawn with OpenFreeMap tiles; the tile server sees your IP address like any web request.
Deleting
Leave a group to stop sharing with it. Email agonisma@metronos.net to delete your account and everything attached to it.
No tracking
No advertising, no analytics cookies, no health-app access. The only cookie keeps you signed in.
