Nocturne
Privacy policy
Effective 23 September 2026.
Nocturne works fully on your device. There is no account and no sign-in, and your data never leaves your device through us.
Who we are
Nocturne (“the app”) is published by Coralia Digital, an independent app studio. “We” refers to the developer who publishes the app on the Apple App Store. Questions? Email coraliadigital@icloud.com.
What data we handle and why
On-device data only
Nocturne stores your content, settings and progress locally on your device using the operating system's standard storage (and, if you use iCloud, your own private iCloud account). We do not have an account system and this data is never sent to us or to any server we control.
Apple Health
With your permission, Nocturne reads data such as your step count from Apple Health. It is read and used on your device only, to power features in the app. It is never sent to us, never shared with third parties, and never used for advertising. You can revoke access at any time in the Health app.
Subscription data
If you buy a subscription or in-app purchase, Apple and RevenueCat process the transaction and tell us whether your purchase is active. We never receive your card details.
Notifications
If you enable reminders, the notifications are scheduled locally on your device. We do not run a push server and do not collect a device push token for this.
What we do not collect
- Location data
- Contacts
- Microphone audio
- Browsing history
- Advertising identifiers (IDFA)
- Any data used for advertising or cross-app tracking
We do not sell your data to anyone, and we do not use it for advertising or cross-app tracking.
Third-party services

Children
Nocturne is not directed at children under 13 and we do not knowingly collect personal information from them.
Your choices
Because your data lives on your device, deleting the app removes it. You can also email coraliadigital@icloud.com with any privacy question.
Changes to this policy
If we change this policy we will update the effective date above and post the new version on this page.
