Email us at support@tayueke.cn with your iOS version, device model, SIMMemo version, and a brief description of the issue.
Missing Reminders
Confirm that SIMMemo has notification permissions enabled, and verify the keep-alive interval and next reminder date for that number. You can also verify notifications in iOS Settings → Notifications → SIMMemo.
iCloud Not Syncing
Make sure your devices are signed in to the same Apple ID and iCloud sync is enabled in SIMMemo settings. Initial sync may take a moment.
Linked Numbers & Accounts
Open any phone number to see its linked accounts, or view an account to check which number it depends on.
Export & Import Backups
Go to Settings → Data Backup. Select Export Backup to save your data, or Import Backup to restore from a previously exported SIMMemo backup file.
Privacy
For details on local storage, iCloud, Keychain, and how data is handled, read the SIMMemo Privacy Policy.
