Grimoire is built with a zero-permissions architecture. The application does not request, hold, or utilize Android network permissions. All drawing detection, gesture mapping, and overlay operations are calculated completely offline, locally on your device CPU. Nothing can leave your device because the app cannot access the internet.
We do not collect, capture, store, or transmit your gestures, logs, system actions, or device characteristics. What you draw stays in your volatile memory and local database and leaves no external trace. Your configuration settings are stored in an encrypted SQLite database on-device.
Grimoire contains zero tracking scripts, analytic metrics, crashlytics reporting, or third-party telemetry systems. It is completely isolated.
