Backup and restore

Export your reminders to a file you control — the safety net for Free and Lifetime users.

Last updated

If you don’t use cloud sync, your data lives only on your phone — so export a backup now and then. A lost or broken phone should never mean losing your streaks.

Exporting

Settings → Export backup creates a single nudje-backup.ndjb file containing your reminders, history, and settings, and hands it to the system file picker — save it to iCloud Drive, Google Drive, Files, or anywhere you like. The file goes wherever you choose; it never touches our servers.

An optional passphrase encrypts the backup (Argon2id + XChaCha20-Poly1305). Without a passphrase, the file’s safety is the safety of wherever you store it — for most people that’s their already-protected cloud drive, which is a reasonable default.

Restoring

Settings → Import backup on any phone — iPhone or Android, the format is identical — reads the file and merges it with what’s on the device: for any reminder that exists in both places, the newer version wins. Restoring on a fresh install simply brings everything back.
