Common questions

Where is my collection stored?

On your device. Longbox is local-first — there's no account and no cloud copy. Use the in-app export to back it up.

Will I lose my collection if I delete the app?

Deleting the app removes its local data, including your collection. Export a backup first if you want to keep it or move to a new device.

An item was identified incorrectly.

Identifications are best-effort. You can edit any field during the confirm step or later from the item screen. Re-taking the photo with the cover flat and well-lit usually improves results.

How do I cancel a subscription?

Manage or cancel subscriptions in your Apple App Store or Google Play account settings — that's where billing lives.

How do I request deletion of my data?

Because your collection lives on your device, deleting the app removes it. For anything else, email privacy@longbox.cool.
