Privacy
Leitner Learning is private by default. Your deck, progress, and settings stay on this device in this browser. The free core does not require an account.
What stays on your device
- Cards, Leitner boxes, and review history
- Stories reading progress
- Pack enables and a license unlock, if you redeem one here
- Voice preference and similar settings
What we do not do
We do not run a learner account database for the free product. We do not sell your study data. We do not use your answers to train third-party AI graders.
License purchases
If you buy a license, Stripe processes the card under Stripe’s privacy policy. Rún AS may receive your email from the receipt so we can help if a code needs to be re-sent. The code unlocks packs and advanced Stories on the browser where you redeem it.
