My passport isn't growing.
Check that Bluetooth and Motion are allowed for Atum in your phone's settings, and that Background App Refresh (iPhone) or battery optimization (Android) isn't stopping Atum. The passport grows only while the phone is with you.

I see "Encounters paused" or "Not verified".
The app shows why under the warning. If you think it's a mistake, write to us with your passport number from Settings → Passport number.

I changed my phone.
The passport lives in the phone's secure chip and can't be moved. Install Atum on the new phone: a new passport starts from day one. Delete the old one if you still have the phone.

I want to delete my data.
See atum.digital/delete.
