Curivana is currently in private preview. An App Store download is not yet available.

Report a lesson correction

Include the course and lesson title, the passage or question, and a source if you have one. You can also use the content-report option in the app. Review anything you choose to send; there is no need to attach your full learning history.

Save or move your history

Open Settings → Export learning history to save a JSON backup. Import learning history merges a backup with existing records. Backups can include your written reflections, so keep them somewhere private.

Manage iCloud sync

Private iCloud progress sync is optional and needs a supported, provisioned device build and an available iCloud account. Changes to the sync preference apply after restarting the app. Turning sync off does not delete history already stored in iCloud.

Delete learning history

Use Settings → Delete learning history. This removes attempts, completed lessons, and reflections. If sync is enabled, deletion propagates when iCloud connects. Keep an export first if you want a backup, and delete exported files separately when you no longer need them.

Reminders and optional explanations

Manage reminder days and times in Settings. Notification permission is controlled in iPhone Settings. Optional generated explanations require compatible Apple Intelligence hardware and an available on-device model; authored explanations remain available.

Free course and planned Library plans

Purchases are disabled in the private preview, where all courses are included. In the planned public edition, How Evidence Works will remain free. A Curivana Library subscription will open additional published courses, with the same access on either plan.

Planned United States prices are US$5.99 per month and US$39.99 per year. The App Store will show your localized price and billing period before purchase. Monthly and yearly plans renew automatically until canceled. See the subscription terms for details.

Manage or cancel a subscription

When subscriptions become available, use Manage subscription in the app, or open iPhone Settings → your name → Subscriptions and select Curivana. Follow Apple’s instructions to cancel. Removing the app or deleting learning history does not cancel a subscription.

Keep completed lessons and restore access

After subscription access ends, completed premium lessons and their associated review remain available with your saved completion history. Keep that history on your device, in iCloud, or in an exported backup. Uncompleted premium lessons require active access.

Restore purchases restores eligible subscription access through your Apple Account. Learning history restores separately through iCloud or a backup; a purchase receipt does not contain your completions or reflections.

Help us understand the issue

Send the app version, your iPhone model and iOS version, and a short description of what happened. Screenshots are optional; remove anything private before sending.
