01

Purchases and restore

The optional upgrade is one non-consumable lifetime purchase—never a subscription. Open Library → Lifetime Collection Access to purchase or restore it with the same Apple Account.

02

Crashes, stalls, or image issues

Please include your device model, operating-system version, app version, the screen you were using, and exact reproduction steps. A screenshot or short recording is especially helpful.

03

Content or rights corrections

For corrections to an artist, date, institution, translation, or rights record, include the artwork title and a reliable source link.

04

Remove local data

Removing a favorite or Looking Record deletes that item. Deleting the app removes all local favorites, drafts, records, and preferences. There is no cloud account to delete.
