Need help with Cairn?

Email cairnfocus@proton.me for support, purchase questions, privacy questions, bug reports, or feature requests.

Helpful details to include

• Your iPhone model and iOS version.
• Whether the issue happens during onboarding, app selection, a puzzle ritual, a release window, settings, or purchases.
• A screenshot or short screen recording if the issue is visual.
• Whether Screen Time and Family Controls permissions are enabled for Cairn.

Common checks

• Confirm Cairn has Screen Time authorization in iOS Settings.
• Confirm the apps you want protected are selected in Cairn.
• If protected apps do not unblock after a solved ritual, reopen Cairn and check the release timer.
• If purchases do not appear, use Restore Purchase in the app.

Privacy
