Privacy Policy
Gongbufit stores your study records only on your device. The operator runs no servers and does not receive or store your study records.
The operator of Gongbufit (the "Operator") provides the Gongbufit app (the "App") and handles your personal information with care. The Operator runs no servers of its own and does not receive or store your study records.
1. What the App stores and where
1-1. Information stored on your device
The App stores the following only on your device and does not send it to the Operator.
- Subject names, study sessions (start and end times, notes), goal times, streak records, exam grades and grade goals, tasks you write (title, subject, due time, done), and exam countdowns you set (exam name and date)
- Daily notes: today's pledge and reflection (the text you write and the mood you pick) and your diary (text and handwriting strokes)
- App settings (student type, grading system, language, exam period mode, bedtime reminder time, Pomodoro times, etc.)
Deleting the App deletes this information too.
1-2. Backup files
Backup files you create with "Backup · Restore" contain the information above. They are saved where you choose (device storage, iCloud Drive, your Google Drive, etc.). The Operator does not access or collect these files. Backup files remain even if you delete the App.
1-3. Google Sign-In and Google Drive backup (optional)
If you want, you can sign in with Google and save backups to a hidden space in your own Google Drive that only this App can access. This is optional, and you can use every feature of the App without signing in.
- The App uses your Google account's email address and name only to show them on screen, and does not send them to or store them on any server of the Operator.
- The only permission requested is access to this hidden space; the App cannot see your other Drive files.
- You can sign out or delete saved backups in the App, and revoke the App's access in your Google account settings.
- The App's use and transfer of information received from Google APIs follows the Google API Services User Data Policy, including the Limited Use requirements.
1-4. Automatic backups by the operating system (Google backup · iCloud backup)
If "Google backup" is on on your Android device, the operating system may back up the App's data to your Google account and restore it on a new device. This is handled by the operating system under Google's policies, and the Operator does not access that data. You can turn off Google backup in your device settings.
If "iCloud Backup" (or a device backup to a computer) is on on your iPhone or iPad, the operating system may back up the App's data to your iCloud account (or computer) and restore it on a new device. This is handled by the operating system under Apple's policies, and the Operator does not access that data. You can turn off iCloud Backup in your device settings.
2. Payments and subscriptions
Subscription payments are processed by Google Play on Android and by the App Store (Apple) on iPhone and iPad. To check subscription status, the App uses RevenueCat, a payment and subscription management service. The following may be processed:
- Subscription and purchase history, and an anonymous app user identifier
- Technical information needed to provide the service, such as device and app version
The Operator does not collect information that directly identifies you, such as your name or contact details. Payment method information is handled by Google or Apple and is not shared with the Operator. RevenueCat's processing follows the RevenueCat Privacy Policy.
When a subscription ends, your saved records are not deleted. Only the features that need a subscription (monthly stats, grade trends and goals, exam period mode, backup · restore) become unavailable.
3. Notifications
The App may ask for notification permission (on Android, including the "Alarms & reminders" permission for on-time reminders) for the bedtime reminder. Notifications are scheduled on your device at the time you set, and you can change the permission anytime in your device settings.
4. Ads and analytics
The App shows no ads and does not use any advertising, behavioral analytics or crash reporting SDKs.
5. Internet connections
The App connects to the internet only for:
- Subscription payments and subscription status checks (Google Play or the App Store, and RevenueCat)
- Google Sign-In and Google Drive when you tap sign in, back up or restore
The App sends no other information about you outside your device.
6. Children and minors
The Operator does not collect information that directly identifies you (name, contact details, etc.). If a minor buys a subscription, the payment policies of Google Play or the App Store may require a parent's or guardian's payment method and consent.
7. Your rights
Because the App's information is on your device, you can view it in the App or delete it by deleting the App. Backup files you created must be deleted where you saved them; backups uploaded to Google Drive can be deleted in the App, or you can revoke the App's access in your Google account settings. You can cancel a subscription anytime in Google Play's subscription management, or on iPhone and iPad in Settings > your name (Apple Account) > Subscriptions. To request deletion of subscription or purchase information, contact us at the address below.
8. International transfer of personal information
To process subscription payments and check subscription status, the following information may be transferred outside your country. Your study records, grades and other in-app records are not transferred.
- Recipients (contact): RevenueCat, Inc. (compliance@revenuecat.com), Google LLC (Google Play payments), Apple Inc. (App Store payments)
- Destination: the United States and other countries where each company's servers are located
- Items: anonymous app user identifier, subscription and purchase history, and technical information such as device and app version
- When and how: sent over encrypted network connections when the App starts, when you buy or restore a subscription, and when subscription status is checked
- Purpose and retention: confirming subscription payments and managing subscriptions; kept for the period set by each company's privacy policy
- How to refuse and what happens: if you don't want this transfer, you can choose not to subscribe. You can still use the free features; only the features that need a subscription are unavailable.
Google Drive backup (1-3), which you choose to use, and the operating system's automatic backups (1-4) are stored in your own Google or iCloud account; the Operator does not receive or transfer that information.
