Brainprint Privacy Policy
Last updated: 14 October 2026
Brainprint ("the app") is made by 2C Studio. This policy explains how the app handles your information. It applies to both versions of the app: the Google Play version and the Solana dApp Store version (for Seeker phones).
Information we collect
The app does not collect, store on our servers, or share any personal information. There is no account or sign-up.
Data stored on your device
Your test results, daily challenge history, badges, practice records and settings are stored only on your own device. You can delete all of this at any time in the app under Me > Delete All My Data, or by uninstalling the app.
Device backup
If you have turned on Android's backup service, Android may back up the app's data to your own Google account so it can be restored on a new phone. This backup is controlled by Android and your Google account, not by us.
Sharing
When you choose to share a result card or a challenge code, the app opens your phone's share menu. What you share, and with whom, is your choice; the app does not send anything by itself.
Notifications
If you turn on the daily reminder, the app shows a local notification on your phone. No data is sent anywhere.
Solana wallet (Solana dApp Store version only)
If you choose to connect a Solana wallet, the app receives your public wallet address through the Mobile Wallet Adapter. The address is stored only on your device. To check whether you hold a Seeker Genesis Token, the app sends your public wallet address to a public Solana network endpoint (api.mainnet-beta.solana.com), which returns your public token holdings. The app never has access to your private keys or recovery phrase. Connecting a wallet is optional. Uninstalling the app removes the stored address. The Google Play version does not include any wallet features.
Children
The app is not directed at children under 13.
Changes
If this policy changes, the updated version will be posted on this page.
