Privacy Policy
Bingbing (hereinafter referred to as the "Developer") values users' privacy and complies with applicable privacy laws and Google Play policies.
1. Personal Information Collected
The App does not provide account registration and does not directly collect personal information such as users' names, email addresses, phone numbers, contacts, or precise location.
2. Data Processed When Using App Features
- Diet lookup: The App communicates with the Developer's server to provide cafeteria menu data. The request may technically include network information such as IP address and user agent as part of normal server communication.
- Barcode storage: Meal ticket barcodes scanned or entered by the user are stored only in the device's local app storage.
- Notifications and widgets: User-selected settings, including notification options and widget display options, are stored on the device.
- Camera: The camera is used only for barcode scanning. Camera images are processed on the device for scanning and are not uploaded to the Developer's server.
3. Data Retention Period
- Locally stored barcode and settings: These remain on the user's device until the user deletes them, clears the App's data, or uninstalls the App.
- Notification schedules: Notification data remains on the device only while the relevant notification settings are enabled or until the notification is delivered, canceled, the App data is cleared, or the App is uninstalled.
- Server-side meal data: Cafeteria menu data stored on the Developer's server is not personal information and may be retained as needed to operate the meal lookup service.
- Server access logs: If generated by the hosting environment for security, troubleshooting, or abuse prevention, logs are retained only as long as reasonably necessary for those purposes and then deleted or rotated.
4. How Users Can Delete Data
- Delete a saved barcode in the App: Open the barcode screen and tap the delete button for the saved meal ticket barcode. The barcode is removed from local app storage.
- Delete notification or widget settings: Turn off the relevant notification options in the App, remove the widget, or reset the App's stored settings.
- Delete all locally stored App data: On Android, go to Settings > Apps > Chungnam National University Cafeteria Helper > Storage > Clear data, or uninstall the App. This deletes locally stored barcodes, preferences, and cached app data from the device.
- Account deletion: The App does not create user accounts, so there is no account data to delete.
5. Sharing With Third Parties
The Developer does not sell, rent, or share users' personal information with third parties. Barcode values and app settings stored locally on the device are not transmitted to the Developer's server.
6. External Services and Servers
- The App uses the Developer's meal API server to retrieve cafeteria menu data.
- The App may use platform or library features for barcode scanning and notifications. Barcode scanning is performed on the device, and camera images are not uploaded to the Developer's server.
7. Changes to This Policy
This Privacy Policy may be updated when App features, data processing practices, or legal requirements change. The effective date at the top of this page will be updated when changes are made.
