Delete Data or Start Over
Use Settings → Delete or Reset only after choosing the narrowest action that fits. Export important records first when you may need them later.
Delete individual records first
For one trip, open it in Timeline and choose Delete Trip. For one tracker, open its settings and use the tracker delete action. This preserves the rest of the app.
Use Delete or Reset for larger changes
Open Settings → Delete or Reset to see the available trip, tracker, and full-reset actions. Read the confirmation carefully; each option lists what it removes.
Consider iCloud before confirming
With iCloud Sync enabled, deleting synced records can affect the shared record on your other devices. A full reset can also remove preferences and device setup that a normal trip deletion leaves alone.
Deletion may be irreversible after the confirmation completes. An exported file is separate from the app and is not removed by resetting AtlasDays.
If you are trying to fix sync
Do not reset first. Check iCloud status and contact support while a device still contains the expected data.
