Privacy Policy

Pentarab built the Calmnest app as a free app. This service is provided at no cost and is intended for use as is.

Privacy First Approach

Calmnest does not collect, transmit, or store any personal data on external servers. All your sleep data, settings, and usage information are stored only on your device and never leave it.

We believe your sleep data is deeply personal. That's why we designed Calmnest to work entirely on your device without requiring internet connectivity or external data storage.

Data Storage

The app stores the following information locally on your device:

• Sleep start and end times
• Sleep induction session progress
• App settings and preferences
• Sleep statistics and insights

All this data is stored using iOS secure storage and is automatically deleted when you uninstall the app.

Third-Party Services

Calmnest does not use any third-party analytics, tracking, or advertising services. We do not integrate with any external SDKs that collect user data.

Your Data Control

You have complete control over your data:

• All data stays on your device
• You can delete individual sleep records in the app
• Uninstalling the app removes all data permanently
• No data backup or cloud sync means no data recovery after deletion

Security

Since all data is stored locally on your device and never transmitted over the internet, your data security depends on your device's security. We recommend:

• Keeping your device password-protected
• Using iOS security features like Face ID or Touch ID
• Keeping your iOS updated with the latest security patches

Changes to This Privacy Policy

We may update this Privacy Policy from time to time. Any changes will be posted on this page with an updated revision date. We encourage you to review this Privacy Policy periodically for any changes.
