Privacy Policy

Last updated: 12 October 2026

StackCards does not collect, transmit or sell any personal information.

What stays on your device

Your collections, cards, tags, notes, images, study history, streak and settings are stored locally.

Two short lists, saved in your own iCloud key-value storage: the event packs you claimed and the missions you finished.

Sync is off by default and uses your private iCloud database.

Premium is handled entirely by Apple through the App Store.

Images you add to cards are copied into the app's own local database.

Study reminders are local notifications scheduled on your device.

Sharing a collection creates a picture or a file that you choose what to do with.

Two features go online, and neither sends anything about you or your cards.

StackCards is safe for all ages.

Updates will be published on this page.
