Privacy Policy

Last updated: 8 March 2026

      The short version: Lunaire stores all your data locally on your device. We do not collect, transmit, or have access to any of your personal or health information. Ever.
    

1. Data Storage

All data you enter into Lunaire — including cycle dates, symptoms, food logs, supplements, and any other health information — is stored exclusively on your device in a local database. Your data never leaves your phone.

2. No Data Collection

Lunaire does not collect, transmit, or share any personal data. Specifically:

No data is sent to our servers (we don't have any)
No analytics or tracking tools are used
No third-party SDKs collect your data
No advertising networks are integrated
No cloud sync or backup services are used

3. No Account Required

Lunaire does not require you to create an account, provide an email address, or sign in with any service. The app works entirely offline and without any personal identifiers.

4. Permissions

Lunaire may request the following device permissions:

Notifications: To send you daily reminders and period prediction alerts that you configure. These are scheduled locally on your device.
Biometric/Screen Lock: If you enable App Lock, to verify your identity before opening the app.

No permissions are used to collect or transmit data.

5. Data Export

Premium users can export their data as a JSON file. This file is generated locally on your device and shared using your device's native sharing mechanism. We have no access to exported files.

6. Premium Features

Lunaire offers optional premium features via in-app purchase. Purchase transactions are handled entirely by Google Play and are subject to Google's Privacy Policy. We do not process or store any payment information.

7. Children's Privacy

Lunaire is not directed at children under 13. We do not knowingly collect any information from children.

8. Data Deletion

Since all data is stored locally on your device, you have complete control over it at all times. You can delete all app data by:

Using your device's Settings → Apps → Lunaire → Clear Data
Uninstalling the app

9. Changes to This Policy

If we ever update this privacy policy, the changes will be reflected on this page with an updated date. Since we do not collect any data, we have no way to notify you of changes other than through this page and app updates.
