[email protected]Screen Time Access
Deefoc uses Apple's Screen Time controls to shield selected apps, app categories, and websites. If blocking does not work, open Deefoc and confirm that Screen Time permission has been granted.
Same-Key Unlock
The same NFC Key that starts a focus session is required to unlock it. If you use a different Key, Deefoc keeps the current session locked.
Privacy
Deefoc does not require an account and stores focus setup locally on the device. Read the full Privacy Policy.
