Privacy Policy
SUUGAKU — Last updated: November 2, 2026
This translation is provided for convenience. If it differs from the Japanese version, the Japanese version prevails.
1. Personal information
The SUUGAKU app does not directly collect or store personal information such as your name, email address or location. There is no account or login.
2. Advertising
The app shows banner ads through Pangle, an advertising service provided by Bytedance Pte. Ltd. To deliver and measure ads, limit how often the same ad appears and prevent fraud, the Pangle SDK may send the information below directly to Pangle.
For how Pangle handles information, see the Pangle Privacy Policy. Pangle Privacy Policy
3. Information handled
The table below lists all the information involved. The developer (Fuji Bit Inc.) does not obtain or keep information that identifies you. Information handled
| Information | Handled by | Purpose | Kept by the developer |
|---|---|---|---|
| Advertising ID (IDFA / Android advertising ID) | Pangle (Bytedance Pte. Ltd.) | Serving ads, measuring impressions, preventing fraud | No |
| Approximate location (estimated from IP address) and device information such as the OS | Pangle (Bytedance Pte. Ltd.) | Optimizing ad delivery | No |
| Ad interaction, performance and crash data | Pangle (Bytedance Pte. Ltd.) | Measuring ads, keeping the SDK working | No |
| Numbers you enter and results | None | Showing results only | No (on your device only) |
| Settings (theme, language, ad choice) | None | Keeping your settings | No (on your device only) |
The app never collects your name, email address, phone number, address, precise location, contacts, photos, audio or health information.
4. Your choices
iOS: The app shows the system tracking permission dialog after launch, and Pangle does not start until you answer it. If you ask the app not to track, the advertising ID is not used and ads are not personalized. You can change this in Settings > Privacy & Security > Tracking, or in the app under the gear icon > Ad settings.
Android: On first launch the app asks whether ads may be personalized, and Pangle does not start until you answer. You will still see ads if you choose Don't allow, but they will not be personalized. You can change this under the gear icon > Ad settings. Your choice stays on your device and is excluded from backups and device transfers, so a new device asks again. You can also delete your advertising ID in the Android settings.
All features of the app work whichever you choose.
5. Retention and international transfer
Information stored on your device is deleted when you uninstall the app. The developer keeps no information, so there is no data for it to delete. Information collected for advertising is handled under Pangle's policies and may be processed on servers outside Japan.
6. Children
The app does not knowingly collect personal information from children under 13. If you are a parent or guardian and believe information about your child has been sent, please contact us.
8. Changes
This policy may change without notice. Changes take effect when published on this page.
