Your study materials

Use materials you own or have permission to process. Do not submit another person's sensitive information or use the service to create abusive or unlawful content. Your content remains yours; processing it is necessary to deliver the features you request.

AI and learning

Generated cards can be incomplete or incorrect. Check source references, correct errors and use your own judgment. Recall Harbor does not guarantee exam results or provide professional advice. Report problematic AI content in the card editor.

Plans and payments

Google Play displays subscription prices, billing periods and applicable taxes before purchase. Plans renew automatically unless canceled in Google Play. Allowances reset monthly in UTC, do not roll over, and are subject to the disclosed input, daily and monthly limits. Temporary outages or safety checks can prevent generation. Saved local study and manual cards remain available without a subscription.

Your device and account

Keep your sign-in secure and export a backup before replacing or resetting a device. We do not synchronize your library automatically. Subscription restoration requires the original study account and Google Play purchase account.

Support

For billing problems, technical issues, access questions or applicable consumer remedies, contact davilamschool@gmail.com. Refund requests are handled under Google Play's applicable policies and your statutory rights. Nothing here limits rights that cannot lawfully be excluded.
