Screeny has no user account, no sign-up, and no server of its own. We do not collect, receive, or store your personal data.
To show you your screen time, Screeny reads app usage information from your device using Android's Usage Access (PACKAGE_USAGE_STATS), a special permission you grant yourself in system settings and can revoke at any time. This includes which apps were used and for how long, how often the device was unlocked, and how many notifications each app sent. Screeny also reads the names and icons of your installed apps so those statistics can be labelled.
All of this stays on your phone. It is written to a local database on your device, it is never transmitted to us or to anyone else, and we have no way to see it. The same is true of everything you create in the app — your goals, per-app limits, focus sessions, streaks and settings.
