Review privacy when another person uses your iPhone

Check the visible surfaces

• Whether someone else knows the phone’s passcode.
• Whether an unlocked DailyCheck screen shows private records.
• What notification previews show before unlocking.
• Whether exports sit in a shared Files folder.
• Whether screenshots or photos contain an update you meant to keep private.

Agree on a practical boundary

“Please ask before opening my check-ins or exports. I will show you the update I want to share.” Use a boundary you can actually maintain on that phone.

Review recipients independently

A phone-use agreement does not change private-share access. Keep the app’s chosen people and the device’s users as separate lists. Use the device owner’s own Apple Account, rather than sharing credentials to support a check-in routine.
