Amathlon Privacy Policy

Effective date: July 1, 2026

Amathlon ("the app", "we") is a sports venue booking and match tracking app. This policy explains what information the app collects, how it is used, and the choices you have. We do not sell your personal information.

Information we collect

Account details — your name, email address, username, and an optional phone number and bio. Passwords are stored only as salted hashes; we cannot read them. If you sign in with Google, we store your Google account identifier and the name/email Google provides.
Profile media — profile pictures, banners, and photos you attach to posts, matches, and awards.
Location — with your permission, your device location is used to show sports venues, courts, and players near you. Your most recent approximate location may be stored to power nearby suggestions. You can deny or revoke location permission at any time in your device settings; the app still works without it.
Activity you create — match results, scores, sports preferences, skill ratings, bookings, squads, posts, comments, chat messages, and your connections (friends and follows).
Device push token — a notification token so we can send you match invites, verification requests, and booking updates. Cleared when you log out or disable notifications.

How we use it

To operate the app: bookings, match logging and verification, ratings, leaderboards, chat, and social features.
To show venues and players near you (location).
To send notifications you triggered or opted into.
To send account emails (verification, password reset, invitations).
To keep the service safe (rate limiting, abuse prevention).

Who can see your information

Your profile (name, username, photo, bio, match record) is visible to other users according to your account visibility setting (public or private). Match results are shared with the other participants of that match. Chat messages are visible to the members of the conversation.

Service providers

We use a small number of processors to run the app:

Cloudinary — stores uploaded images.
Expo — delivers push notifications.
Google — optional sign-in.
DigitalOcean — hosts our servers and database.
Sentry — receives error and crash reports so we can fix problems (details below).
TheSportsDB — provides public professional sports scores; no personal data is sent to it.

Diagnostics and crash reports

When the app or our servers encounter an error, we send a crash report to Sentry, our error-monitoring provider, so we can diagnose and fix it. These reports contain the error, a stack trace and an anonymous request identifier. They are configured not to include request headers, cookies or request bodies, so they do not carry your password, authentication tokens or the content of your messages. Sentry processes this data only on our instructions.

Payments

Court bookings are paid directly at the venue. We do not collect or store payment card details, and no payment processor SDK runs in the app.

Data retention and deletion

Your data is kept while your account is active. You can permanently delete your account at any time in the app under Profile → Settings → Delete Account. Deletion removes your personal details (name, email, username, phone, photos, location, sign-in identifiers) and your social connections. Match results and messages you shared with other users are retained in anonymized form ("Deleted User") to preserve their records. You can also request deletion by emailing the address below. Encrypted database backups are kept for up to 14 days and then destroyed, so deleted data also ages out of our backups within that window.

Children

Amathlon is not directed at children under 13, and we do not knowingly collect personal information from them.

Changes

If this policy changes materially, we will update this page and the effective date above.
