What we store

When you play without an account, nothing leaves your device:

When you sign in

Signing in is optional and powers the ranked leaderboards. If you sign in, the following is stored on our Supabase backend:

Your password is never stored. Authentication is handled by Supabase Auth, which stores a secure hash of your password. The app itself never receives or stores your password in plain text.

Data processor

Supabase provides the infrastructure (authentication, database, and server-side score verification) and acts as a data processor for the data you submit when signed in. We keep the stored data to what the game needs — there is no separate analytics pipeline and no data is sold or shared for advertising.
