Privacy

A session cookie, your username, a salted password hash, a hashed recovery code, your flights, friend links, group memberships and any feedback you send. We do not ask for email, phone or real name.

When you first play, we create an anonymous guest record tied to a cookie so your progress survives a refresh.

Your username and finished daily altitude appear on public boards and to friends and group members. Duel opponents see your username and round results.

We use one HttpOnly session cookie and local storage for your theme choice. There are no advertising or analytics trackers.

On the account page you can download all your data as JSON or delete your account. Deletion removes your flights, friend links and the groups you own.

The site runs on Cloudflare Workers with a Cloudflare D1 database. Cloudflare processes requests as our hosting provider.
