Data and backups

Your WULU archive is stored only on the current device by default and is not synced automatically. Before changing devices, deleting the app, or clearing system data, create a full backup under Settings → Data & Backup and make sure the file is saved somewhere safe. On iOS, WULU Pro can also save a full backup to your own iCloud Drive manually.

Subscriptions and restoring purchases

Subscriptions and the lifetime purchase are managed by the App Store or Google Play. After switching devices, tap “Restore Purchases” in WULU under Settings → Membership. To cancel a subscription or request a refund, go to your account settings in the relevant store. See the Terms of Service.

Analytics and crash reports

If you would like to help us diagnose problems, turn on “Help Improve WULU” under Settings → Privacy & Analytics. It is off by default and never uploads photos, item names, notes, or valuations.

Privacy questions

For the scope of data handling, third-party services, and how to turn them off, see the WULU Privacy Policy.
