1. The most important points
- Your diary (daily lines, mood skies, photos), to-dos and routines are saved on your iPhone.
- The Operator does not run a server. The contents of your diary are never sent to the Operator, to ad companies, or to anyone else outside the App. The Operator cannot see your diary.
- The App does not include any analytics tools (analytics SDKs) that track how you use it.
- The App communicates with outside services only for ads (Google AdMob) and for purchases made through Apple.
2. Information saved in the App
| Diary | Daily lines, sky (mood), and the one photo you choose |
|---|---|
| To-dos and routines | Content, date, notification time, and whether it is done |
| AI weekly summary | The text of summaries that were made |
| Other | Coins and decorations, screen settings, whether the lock is on or off, etc. |
This information is saved only on your iPhone and used only for the App’s features.
Photos
The App imports only the one photo you select in the iPhone photo picker. It does not ask for access to your whole photo library.
Face ID / passcode lock
When the lock is on, the App checks Face ID or your passcode when it opens. The check is done by your iPhone (iOS), and the App only receives whether it succeeded. Biometric information such as face data never reaches the App or the Operator.
Notifications
Notifications for to-dos and routines are scheduled and shown on your iPhone (local notifications). No information is sent to a server for notifications. You can change notification permission anytime in the iPhone Settings app.
3. AI weekly summary
The Premium “weekly summary” is made on your iPhone using the language model Apple provides on iPhone (Apple Intelligence Foundation Models). The contents of your diary are not sent to the Operator or any third party to make the summary.
The weekly summary is not available on devices that do not support Apple Intelligence, or when it is turned off.
4. Ads (Google AdMob)
If you do not use Premium, ads (banners) are shown at the bottom of some screens. Ads are provided by “Google AdMob,” an ad service of Google LLC.
Google states that, to show ads, its program (SDK) may collect information such as:
- IP address (may be used to estimate approximate location)
- Crash logs
- App performance data (such as launch time)
- Device identifiers (such as the advertising identifier)
- Advertising data (such as ads shown)
- Interaction data (such as whether you tapped an ad)
In addition, to ask for ad consent where local rules require it, Google’s consent tool (User Messaging Platform) may use approximate location, app performance data and interaction data.
The App does not give Google the contents of your diary, to-dos or routines.
For how Google handles information, see the following pages:
- Google Privacy Policy
- How Google uses information from sites or apps that use its services
- Google ad settings (My Ad Center)
Ads are not shown while you use Premium.
5. Tracking permission and how to change ad consent
When you first use the App, your iPhone asks whether you allow it to track your activity across other companies’ apps and websites (App Tracking Transparency).
- If you allow it: the advertising identifier is passed to Google, and you may see ads tailored to you.
- If you do not allow it: the advertising identifier is not passed. Ads are still shown, but they may not be tailored to you. The App’s features work the same either way.
To change this later:
- In the iPhone Settings app, go to Privacy & Security > Tracking, and turn the switch for the App on or off. (Apple’s explanation)
- If you were asked for ad consent because of local rules, you can change your choice from “Ad privacy settings” on the App’s Settings screen.
6. Purchases (Premium and coins)
Purchases, renewals, cancellations and refunds of Premium and coins are handled by Apple’s App Store. Payment information such as credit card details does not reach the Operator. Through Apple’s system (StoreKit), the App only checks whether Premium is active and the transaction IDs of coin purchases and refunds.
Coin balances (coins earned, bought and used) and the transaction IDs used to avoid adding coins twice are recorded only on your iPhone and are not sent to the Operator’s server.
7. Where information is stored, and how to delete it
- The App’s information is stored on your iPhone. The Operator does not hold it. For this reason, the Operator cannot see it, delete it for you, or restore it.
- Deleting the App from your iPhone deletes all of the App’s information. Deleted information cannot be recovered.
- If iCloud Backup or backup to a computer is on, the App’s information may be included in that backup. Restoring your iPhone from a backup may also restore the App’s information. Backups are handled according to your Apple settings.
- For information Google collects for ads, see the Google pages above.
8. Use by children
The App is not made for children. Minors should get permission from a parent or guardian before purchasing Premium or Coins.
9. Changes to this policy
This policy may be revised, for example when the App’s features or laws change. For major changes, the Operator will give notice on this page or in the App. Revisions take effect when they are posted on this page.
