Privacy policy
Blindfold Master is designed to work without an account or a server connection. This policy explains what the app does with information on your device.
Information processed on your device
When you use camera scanning, the app processes the camera image on the device to recognize cube colors. Cube states, memo sessions, settings, and exported images are kept on your device unless you choose to share or back them up using an iOS feature.
Information we collect
Blindfold Master does not require registration and does not intentionally collect your cube scans, memo history, or practice data on a remote server. The App Store, Apple, and your device may process information under their own policies.
Camera permission
The camera is used only when you choose the scanning workflow. You can disable camera access at any time in iOS Settings; manual entry remains available.
Children
The app is not directed to collecting information from children. We do not knowingly request personal information from children.
