Privacy Policy | Brain Brawl

Brain Brawl is a mobile game of quick brain-training challenges. This page explains what the app collects, why, who handles it, and how to delete it. Questions go to support@brainbrawl.gg.

The short version: we collect what the game needs to work and what helps us improve it. We don't sell your data, show ads, or track you across other apps and websites.

What we collect

Your account. The app starts you on a guest account, with no email needed. If you save your account, we store your email address, or the sign-in details Apple or Google share with us. We also store the display name you pick and a few app settings.

Your games. Scores, Daily results, training level progress, personal bests and badges. Daily results also record your platform and app version.

Your display name and scores are public to other players on the leaderboards.

Extra data during the beta

While Brain Brawl is in beta, the app also records:

How you play: which games you open, how your brawls end and how long they last.
What you send us: game reviews, "Something looks off" reports and notes. Reviews and reports include your phone model, app version and the screen or game you were on.
Screenshots: a report can include a picture of the app screen you were on. Screenshots show only the app, are never taken during a Daily, and are never saved to your photos.
Invites: your invite code, who entered it, and how many times an invite link was opened. Those link counts aren't tied to the person who opened the link.

A copy of each review and report goes to a private channel that only the developer can see.

Motion sensor

The app reads your phone's motion sensor while it's open so that shaking the phone can open a report. The motion readings stay on your phone and aren't stored or sent to us.

How we use it

To run the game: your account, progress, Dailies and leaderboards.
To fix problems and improve the game.
To answer you when you contact us.

Who handles it

We only share data with the services that run the game:

Supabase hosts the database, sign-in, stored screenshots and the game's server code.
Discord hosts the private channel for beta reviews and reports.
Apple and Google handle sign-in if you choose them. Apple also runs TestFlight and the App Store, under its own privacy policy.
Vercel hosts this website.

We may also disclose information if the law requires it.

How long we keep it

Account and game data stay until you delete your account. Game reviews are kept for up to six months after Brain Brawl's public launch. Other beta data is kept until the beta ends. Deleting your account removes all of it sooner. If you sign in to an existing account from a guest account, that guest account and its data are deleted.

Deleting your data

You can delete your account in the app: open Account, then Settings, then Delete account. That deletes your account, game data and beta data, including the screenshots and the copies in the private channel. You can also email support@brainbrawl.gg to ask for a copy of your data, a correction, or deletion.

Children

Brain Brawl isn't directed at children under 13, and we don't knowingly collect their data. If you believe a child has given us data, email us and we'll delete it.

Security

Data travels over encrypted connections, and each player's private data is restricted to their own account. No system is perfectly secure, but we work to protect what you trust us with.

Changes

If this policy changes, we'll update this page and the date at the top.
