App lock and privacy
App lock protects your medication information from anyone who picks up your phone — even if it's unlocked.
What it does
When App lock is on, DoseAlert shows a lock screen when you open the app or bring it back from the background. You have to authenticate with Face ID, Touch ID, or your phone's passcode before you can see your medication list, dose history, or reminder settings.
Reminder notifications still come through normally even when the app is locked — the lock only applies to opening the app itself.
Turning it on
- Open Settings > Privacy > App lock.
- Turn the switch on.
- Confirm with Face ID, Touch ID, or your passcode.
What "returning from background" means
DoseAlert re-locks when you fully leave the app — switch to another app, go to the home screen, or lock your phone. A brief dip (for example, tapping a notification from the lock screen) doesn't trigger a re-lock.
If biometrics fail
If Face ID doesn't recognise you or your fingerprint is unclear, the lock screen falls back to your phone's passcode. You can't lock yourself out of DoseAlert — if your passcode works for your phone, it works here.
Turning it off
Open Settings > Privacy and turn off the App lock switch. You'll be asked to authenticate once more to confirm.
DoseAlert never sees your biometrics
Face ID and Touch ID verification happens entirely inside your phone's secure hardware. DoseAlert just asks your phone "is this the right person?" and gets back a yes or no — it never sees your face or fingerprint.
Things App lock does not do
- It doesn't encrypt your medication data beyond what your phone already does.
- It doesn't protect against someone with access to your iCloud or Google account backups.
- It doesn't hide the medication list from notification previews on the lock screen. To hide those, change your phone's notification preview settings.
When to turn it on
- You share a phone with family.
- You leave your phone unlocked on a desk sometimes.
- You want an extra layer of privacy on sensitive medication info.
