Use of the app
Cairn is licensed to you, not sold. You may use Cairn for personal journaling and productivity purposes. You may not reverse-engineer, distribute, or use Cairn commercially without written permission.
Subscriptions
Cairn offers auto-renewable subscriptions (Core at $3.99/month and Pro at $7.99/month, with annual options). Subscriptions are processed through the Apple App Store. Payment is charged to your Apple ID account at confirmation of purchase. Subscriptions automatically renew unless cancelled at least 24 hours before the end of the current period. You can manage and cancel subscriptions in your Apple ID Account Settings.
The 7-day free trial is available once per Apple ID per subscription group. After trial expiry without subscription, access is limited to 3 journal entries per week.
Your content
Your journal entries, voice recordings, and all content you create in Cairn remain yours. We claim no ownership or licence over your content. We do not access your content stored on-device.
