Nothing. There is no account, no server, no analytics and no advertising in this game.
The game writes two keys to your browser's local storage:
| Key | Contents |
|---|---|
brewbeat.scores.v1 |
Your top five scores per track: score, max combo, accuracy, rank, date. |
brewbeat.settings.v1 |
Latency offset, effect quality, note speed, music and hit-sound volume. |
Both stay on this device. Clearing your browser's site data, or the Clear all records button on the Records screen, removes them.
Audio files and beatmap JSON you open — in the game or in the editor — are read in the browser and never uploaded. They are gone as soon as you close the tab.
When this game is played on itch.io, itch.io's own privacy policy applies to their page around it. The game itself makes no network requests beyond loading its own files.
