How do I delete my data? Your cards and goals are stored on your device. If you use Auto-Backup, a copy is also saved to your personal Google Drive or iCloud, which only you can access. We do not have access to any of this data. To remove it, delete the app and clear any backups from your Google Drive or iCloud.

How do I move my data to a new phone? You can use the Manual Backup & Restore feature in Settings to export a .marks file and import it on your new device. Alternatively, you can use the new Auto-Backup feature and restore from your latest backup directly in Settings on your new device.

How do I cancel my subscription? On Apple: go to your iPhone's Settings → Apple ID → Subscriptions, find Marks, and cancel from there. On Android: open the Google Play Store, tap your profile icon → Payments & subscriptions → Subscriptions, find Marks, and cancel from there.
