Rubai Journal privacy policy
Last updated: 11 October 2026
1. Who we are
Rubai Journal is developed by KapricornX. Questions about privacy: support@kapricornx.com
2. What the app stores on your device
Rubai Journal has no account and no sign-in. The app stores the following in its private storage on your device:
- the memories you write: title, text, date, and the categories you choose;
- copies of the photos you attach to a memory;
- the custom categories you create;
- the books you make (PDF files) and their titles;
- settings: theme, whether the daily reminder is on and its time, whether App Lock is on, the names you give your shelves, the date of your last backup, which daily verses were shown recently, and whether Lifetime Unlock is active.
Further values are kept in the same settings file, each for a specific purpose:
- the date the app was first opened, and a count of memories written, which the app uses to work out which memories count as part of the free trial window (7 days or the first 30 memories);
- whether your free book has been made, and whether you have dismissed the notice that the free window has closed;
- a number from 0 to 26 that the app picks at random the first time it runs. It decides which share-card designs are free for you. It is not derived from your device or from you.
The app's own code does not read or store a device identifier such as the Android ID.
3. Photos and sharing
To attach photos, the app asks Android to open its photo picker. On some Android versions, Android may show a different system chooser instead. In either case you choose the photos, and only the photos you choose are handed to the app; the app does not request broad access to your photos or media. Selected photos are copied into the app's private storage. When you share a story card or a book, the app hands the file to the app you choose in the Android share sheet. Nothing is shared unless you do this.
4. Purchases
Lifetime Unlock is sold through Google Play. The app does not receive your card or other payment details. To check whether you own Lifetime Unlock, the app asks Google Play when it starts and when you return to it. Google Play returns a record of the purchase (such as an order number, the product, the purchase time and status, and a purchase token). The app checks this record on your device and stores only whether Lifetime Unlock is active. The app's own code does not send this record anywhere.
5. Backups
(a) Backup files you create yourself. In the Me tab you can create a backup file, with or without a password, and choose where it is saved. The app writes the file to the location you choose. If you choose a location managed by a cloud service, that service may store the file under its own terms. The app itself does not send the file anywhere.
(b) Android's own backup. If backup is turned on in your device settings, Android may copy the app's settings file to your Google account. The app's backup rules allow only this settings file in Android's cloud backup: it holds the settings and the further values listed in section 2, including the names you give your shelves and the date the free trial started, so that deleting and reinstalling the app does not start the free trial over. The backup rules do not include your memories, photos or books in this cloud backup. If you move to a new phone using Android's device-to-device transfer, Android 12 and later can transfer your memories, photos, books and settings under these backup rules. On Android 11 and earlier, the current rules transfer only the settings file, so use a backup file (see (a)) to move your memories, photos and books.
6. Network use
The app's own code does not send your memories, photos, books or settings over the network, and the app has no server of its own. The app includes Google's Play Billing Library to sell and check Lifetime Unlock. This library communicates with Google Play. It also contains a component that sends diagnostic event data about the library's operation to Google. We have not determined the full contents of these events; they may include technical information about your device, such as its model or system version.
7. Permissions and background work
- Notifications and an alarm at the time you choose: the optional daily reminder. It is created on your device; it is not a message from a server.
- Restarting that reminder after your phone restarts.
- Biometric / screen lock: used only if you turn on App Lock. Android shows its own prompt and tells the app only whether you unlocked; the app does not receive your fingerprint, face or PIN. While App Lock is on, the app's screen is blocked from screenshots.
- Google Play Billing: for Lifetime Unlock.
- Internet and network-state access: declared by libraries the app includes. Internet access comes with the Google Play Billing Library's components (see section 6); network-state access also comes with Android libraries such as WorkManager. The app's own code does not use the network.
- Foreground-service permissions: declared by Android's WorkManager library, which the app includes. The app's own code does not start a foreground service on Android.
8. Keeping and deleting your data
- A memory you delete goes to Trash and is removed for good after 30 days, together with its photo copies. "Empty Trash" removes it at once.
- Deleting a book removes its PDF file.
- Uninstalling the app removes the data stored in its private storage on your device. It does not remove backup files you saved yourself, copies held by a cloud service you chose, or Android's cloud backup in your Google account, which you manage in your Google account settings.
- Temporary files. While you share a card or create or restore a backup, the app writes temporary files to its private cache and deletes them when that action finishes. When you share, the sharing component the app uses may keep its own copy of the item in the app's cache, normally until you share again. If the app is stopped before it can clean up, for example by the system, the app deletes these leftover files the next time it starts, once they are more than a day old. Android may also clear the app's cache on its own.
9. Children
Rubai Journal is designed for adults (18 and over) and is not directed at children.
10. Changes
