Thank you for using MoodJournal. A diary is deeply personal, and protecting it is our first priority. This policy explains how we handle (and do not handle) your information. In short: your diary stays on your own device by default, and we serve no ads and use no third-party tracking.
Your diary is stored locally on your device by default. Cloud storage is explained in Section 4. Uninstalling the app deletes local data, so please back up first.
Version 1.9 and later of the iOS app offer free JSON backup export and restoration from JSON files. CSV export is a membership feature for viewing data in spreadsheets and cannot restore entries. You choose where to save or share exported files.
From version 1.9 of the iOS app, app lock is free and off by default. The system verifies your identity using Face ID, Touch ID or your device passcode; the app cannot read or store your facial or fingerprint authentication data or device passcode. The setting is stored only on this device and is not synced with diary backups. App lock does not create a separate diary password or add password protection to exported backup or CSV files.
You do not need an app account to purchase or restore App Store membership. Signing in to an existing account is for the original server backup service or retrieving past entries. Sign-in information is used only to identify the account, locate backups and support legacy membership records. You can delete the account in the app. The following sign-in methods are available:
iCloud backup is off by default and members choose whether to enable it. It requires signing in to iCloud in system settings and uses your iCloud storage. Apple provides this service. Entries are stored in the private space of your current iCloud account and are not uploaded to our diary backup servers.
When iCloud sync is on, edits and deletions also sync to participating devices. Turning backup off or membership expiring does not delete local or cloud entries. Expiry pauses automatic sync; existing iCloud backups can still be restored manually for free. When sync is enabled again, entries explicitly deleted while it was off are also deleted from the cloud.
Existing server backup users keep the original service. After iCloud has been enabled, signing in to an old account only retrieves and merges past entries; it does not change the backup service.
With Cloud Backup enabled, your diary is encrypted and uploaded to our servers, solely to back up and restore across your devices. We do not read or analyze your diary, do not use it for profiling or training, and never share it with third parties (except where legally compelled). You can turn backup off at any time; deleting your account also deletes your server-side backups. Diary text is encrypted on your device with AES-256 before it is uploaded.
The app has no third-party advertising or behavioral tracking SDKs and does not use IDFA. Communication with our servers, such as signing in to an old account or restoring past entries, generates basic technical logs including IP address, request time and device type. These are used only for service operation, security and troubleshooting, and kept only as long as necessary for those purposes. Apple handles communications relating to the iCloud service.
Membership subscriptions and one-time purchases are handled entirely through Apple App Store in-app purchase. Payment details are processed by Apple; we cannot see or store your payment method. To manage or cancel a subscription, go to Settings → Apple Account → Subscriptions.
If you use Cloud Backup, your encrypted backup data may be transferred to servers located outside your country or region. Where such transfers occur, we apply appropriate technical and contractual safeguards.
The app is not directed at children under 13 (or a higher age where required). We do not knowingly collect personal information from children; if you believe a child has provided us personal information, contact us and we will delete it.
We may update this policy from time to time. Material changes will be communicated in the app. The updated policy takes effect upon publication.
