Mouna Privacy Policy

1. Our Core Philosophy: Zero Data Harvesting

Mouna was built to be a safe, private sanctuary for your mind. We believe your thoughts, worries, and anxiety patterns belong strictly to you. We do not collect, read, transmit, or sell your personal journal entries or audio recordings — they stay on your device unless you save a backup file yourself. The app does connect to Google Play for purchases, updates and ratings; section 4 sets out exactly what that involves.

2. How Your Data is Stored (On Your Device)

• Text & Voice Notes: Your journal entries, sealed worries, and audio recordings are saved locally to your device’s internal storage. They are never uploaded to a cloud server or database owned by us.
• Resolved Worries: When you resolve a sealed worry, Mouna erases what you wrote or recorded for it, including any name you gave it. Only its outcome, dates and jar are kept, so your statistics and Sky still count it.
• Analytics & Progress: Your Resilience XP, Constellation progress, and jar statistics are calculated and stored locally on your device.
• Android Backup: Mouna tells Android to leave its data out of Google’s automatic cloud backup and out of phone-to-phone transfer. A backup file you make yourself is the way to move your data to another phone.
• Backup Files: If you choose “Back up to a file”, Mouna writes your jars, worries, voice notes, diary notes, check-ins, settings and purchase identifier into one file encrypted with a password you set, and saves it wherever you choose — for example your phone’s storage, a USB drive, or a cloud drive such as Google Drive. We never receive the file or the password. If you save it to a cloud service, that service’s own privacy policy applies to the stored file. The password cannot be recovered; without it, the file cannot be opened.
• Biometric Security: If you enable Fingerprint, Face Unlock, or PIN lock within Mouna, the app relies purely on your device’s native Android security. We do not have access to your biometric data.

3. Permissions We Request

To provide Mouna’s core features, the app requires the following device permissions:

• Microphone: Required exclusively to record voice notes for your worries and tracking diaries. The audio files are saved locally on your device and are never transmitted over the internet by Mouna.
• Notifications: Used for a daily reflection reminder and, if you turn them on, hourly check-ins; to alert you when a sealed worry is ready to review; and to ask after a worry you’re tracking when its diary has been quiet for three days. All notifications are scheduled and generated locally on your device. No notification content is sent to any server.
• Alarms & Reminders: If you enable check-in reminders, we ask for permission to schedule exact alarms so your reminders arrive on time even when your device is in battery-saving mode. This permission is used only to schedule your local reminders.
• Battery Optimization: We may optionally ask you to exempt Mouna from battery optimization so reminders are delivered reliably. This is entirely optional and only affects how your device schedules Mouna’s local notifications.
• Other Permissions: Mouna also uses vibration for gentle haptics (you can turn these off in Settings), restores its scheduled reminders after your phone restarts, uses fingerprint or face unlock only if you turn on App Lock, and uses the internet only for the services in section 4. It requests no storage permission: backup files are saved and opened through Android’s own file picker, which gives Mouna only the one file you choose.

4. Third-Party Services

Your journal never leaves this device unless you save a backup file yourself (section 2). The app itself does talk to Google Play — for purchases, for update checks, for the rating prompt, and for the diagnostics those Google libraries send about themselves. None of it carries your journal content. Everything Google Play does here is listed below.

• RevenueCat: We use RevenueCat to manage our premium entitlements and verify if you have purchased Mouna Pro. RevenueCat collects an App User ID (a random identifier Mouna creates on your device, with no link to your name or email), device type, OS version, country, and purchase timestamps to validate your purchase receipt with Google Play. If you make a backup file, this identifier is stored inside it, so restoring the backup can bring your purchase back. They do not have access to your name, email, or any of your journal entries.

• Google Play Billing: Purchases are processed securely through Google Play. We do not collect or store your credit card information.
• Google Play Updates: When you open the app, it checks Google Play for a newer version so you can update in-app. This check is handled by Google Play services and does not include any of your journal data.
• Google Play In-App Review: After your second worry resolves well, Mouna may ask you, once, to rate it. The prompt is shown by Google Play, which handles your rating and review directly; we never see who left one, and no journal content is involved.
• Google Play services diagnostics: The Google Play libraries above send Google their own technical diagnostics — how those libraries themselves performed — shortly after the app starts. This is Google’s own reporting about its own software. It contains none of your worries, recordings, check-ins or statistics, and we neither request nor receive it.

5. Data Deletion

Because your data is not stored on our servers, you have total control over it. You can permanently delete your jars, worries, diaries, voice notes, check-ins and statistics at any time using "Delete All Data" in Mouna’s Settings, or everything by uninstalling the app from your device. Delete All Data keeps your settings and the random purchase identifier, so Mouna Pro keeps working.

Mouna does not back itself up to any cloud. Unless you have saved a backup file, deleting your data or uninstalling the app will result in the permanent, unrecoverable loss of your journal entries. “Delete All Data” does not affect backup files you have saved elsewhere; you can delete those yourself.

6. Data Retention

We do not operate any servers or databases that store your personal data, so we retain none of your journal content ourselves. Everything you create in Mouna is retained only in local storage on your own device, for exactly as long as you choose to keep it there.

• On-device content (journal entries, sealed worries, voice notes, mood check-ins, Resilience XP, and statistics): retained locally on your device until you delete it within the app or uninstall Mouna. It is never transmitted to us, and we retain no copy of it. Backup files you create are kept wherever you saved them, until you delete them.
• Purchase-validation data (Mouna Pro): the App User ID and purchase records used to verify your Mouna Pro entitlement are retained by RevenueCat and Google Play in accordance with their own retention policies. This data contains none of your journal content and nothing that personally identifies you to us.

Because none of your content ever reaches us, there is nothing for us to retain, back up, or delete on your behalf — you remain in complete control of how long your data lives, at all times.

7. Children's Privacy

Mouna does not knowingly collect personally identifiable information from children under the age of 13, as we do not collect any personal data to begin with.

8. Changes to This Policy

We may update this Privacy Policy from time to time to reflect changes in our app or legal requirements. Any updates will be posted on this page with a revised Effective Date.
