Saju Note Privacy Policy
Effective date: October 19, 2026
Suki App Studio ("we") explains below what information the Saju Note app ("the app") handles.
1. Information the app handles
- Chart details: name or nickname, date and time of birth, solar or lunar calendar and leap month, sex, birthplace (city), relationship, memo, and which chart is yours.
- App settings: view, text size, theme, language, calculation options and similar.
- This information is stored only in the app's private storage on your phone and is never sent to us. We run no server and have no user accounts.
- Charts are calculated on your phone without a network connection.
2. Other people's information
When you enter another person's birth details, for compatibility or family charts, please get that person's consent. Charts viewed without saving stay in the recently viewed list (up to 10) and can be removed on the People screen.
3. Backup and export
- If Google backup is turned on for your phone, saved charts and app settings may be backed up to your Google account. Google handles that backup under its own policy, and we cannot see it. Charts viewed without saving are not backed up.
- A file made with "Export people" in Settings is saved where you choose, and you decide how it is kept and shared.
4. Ads
- The app is free and shows Google AdMob ads. Google may process device identifiers such as the advertising ID, your IP address and ad view and click data to show ads, measure them and prevent fraud. Chart details are not used for ads.
- Where the law requires consent, Google's consent form (UMP) asks you first, and ads are requested only after that. You can change your choice at any time under "Ad privacy settings" in Settings.
- You can reset your advertising ID or turn off personalized ads in your phone settings.
- How Google uses information: https://policies.google.com/technologies/partner-sites
5. Permissions
The app uses only the internet and network state permissions, for ads. It does not use location, contacts, camera or file storage permissions. Birthplaces are picked from a city list built into the app, and backup files are saved with the system file picker.
6. Retention and deletion
Charts stay on your phone until you delete them. Deleting them on the People screen, clearing the app's data in phone settings, or uninstalling the app removes them. We hold none of this information, so there is nothing for us to delete.
7. Children
The app is not directed at children under 13.
8. Changes
If this policy changes, we will post the new version with its effective date in the app and on this page:
