Delete your data

Vaddi Book has no account and no server. Everything is on your phone, so you can delete it yourself. There is nothing for us to delete.

Delete the book from your phone

Deleting cannot be undone. If you may want your records later, save a backup file first.

1. Open your phone’s Settings.
2. Tap Apps, then tap Vaddi Book.
3. Tap Storage, then tap Clear storage. Or uninstall the app.

Menu names can differ a little from phone to phone.

Delete backup files you saved

Open your phone’s Files app and find files with names like vaddi-book-2026-10-13.json. Delete them. If you sent a backup file to someone or to cloud storage, delete it there too.

Delete Android’s backup from your Google account

1. Open the Google Drive app.
2. Tap Menu, then tap Backups.
3. Choose your phone’s backup, then tap Delete backup.

This deletes the whole backup of that phone, not only Vaddi Book. To stop future backups, open Settings, then Google, then Backup, and turn backup off.

Reset or delete your advertising ID

1. Open Settings, then Privacy, then Ads. On some phones, open Settings, then Google, then Ads.
2. Tap Delete advertising ID, or tap Reset advertising ID.

Clearing the app’s storage also clears your ad consent choice. The app asks again before it shows an ad.
