Privacy Policy

Last updated: 30 August 2026

What we collect

If you create an account, we collect your email address and, if you choose to set them, a display name and country — used to identify you in Match History and Grid Rivals. Your match history, sticker collection, and achievements are stored against your account so they carry across devices.

If you play without an account, your match history, sticker collection, and achievements are stored only in your browser (local storage) and never leave your device.

How we use it

Solely to run the game: authenticating you, saving your progress, and showing your stats back to you. We don't sell your data or share it with third parties for marketing.

Cookies

We use a session cookie to keep you signed in. If we enable advertising on this site, our ad provider may set its own cookies to serve and measure ads — we'll update this page when that happens.

Third parties

Account data and game data are stored with Supabase, our database and authentication provider. The site is hosted on Cloudflare. Neither uses your data beyond providing that infrastructure to us.

Your choices

You can update your display name and country any time from your profile page. You can also permanently delete your account — profile, Match History, Sticker Album, and achievements — yourself from your profile page's "Danger zone", or by contacting us at the address below.
