Brainstreak is a quiz game made by ZappFlux. This policy explains what happens to your data when you use it.
Nothing. Brainstreak has no account or sign-up, and it does not connect to the internet. It does not collect, send or share any personal information, and it contains no advertising or analytics code.
To keep your progress, the app saves the following only on your device: your XP and level, your daily streak, your personal best scores, your achievements, your latest Daily Challenge result, and which questions you have answered right or wrong (so it can bring your mistakes back later).
This data never leaves your phone through the app. Deleting the app or clearing its storage in Android's settings removes all of it. If you use Android's own device backup, Android may include this app data in that backup, under Google's policies.
If you tap Share, the app hands a short text (for example "Brainstreak Daily #9 8/10" and a row of coloured squares) to the Android share menu. It goes only where you choose to send it.
Brainstreak does not collect personal information from anyone, including children.
If a future version starts collecting any data (for example to show ads), this policy will be updated before that version is released, and the "Last updated" date above will change.
