2B Studio makes small iOS apps. This policy explains how our apps and support channels handle information.
Our apps do not collect personal information unless a specific app clearly says otherwise.
We do not sell personal information. We do not use third-party advertising trackers.
If you contact us by email, we receive the email address you use, the contents of your message, and any information you choose to include. We use this only to reply to support requests, bug reports, or questions.
Where possible, app data is stored on your device. If a future app adds account features, cloud sync, social features, or AI services, this policy will be updated before release.
Applies only to Guang (光). If you use another 2B Studio app, you can skip this section.
Guang reads the date and location that your camera already wrote into your photos, and uses them to light up the cities you have been to. Your photos stay in your iPhone photo library. We do not upload, copy, or back them up, and all statistics are calculated on your device.
The map in Guang is provided by Mapbox. When the map is shown, the app requests map tiles from Mapbox. That request carries the area of the map you are currently looking at, along with basic device information such as device model, operating system version, and Mapbox SDK version.
Mapbox telemetry (anonymous usage and location reporting) is turned off by default in Guang. You can turn it on or off yourself at any time inside the app, under You → Privacy → Mapbox anonymous usage statistics (在 App 裡是「我 → 隱私 → Mapbox 匿名使用統計」).
We do not send your photos, the contents of your photo library, or the list of cities the app has found to Mapbox, or to anyone else.
Mapbox has its own privacy policy: mapbox.com/legal/privacy.
We may use information provided by Apple, such as crash reports, diagnostics, and App Store analytics, to understand and improve our apps. This information is handled according to Apple's privacy practices and your device settings.
Our apps are not designed to knowingly collect personal information from children. If you believe a child has provided personal information to us, contact us and we will delete it where applicable.
Support emails may be retained as long as needed to handle the request and maintain a record of app support. You may request deletion of support correspondence by contacting us.
For privacy questions or deletion requests, contact privacy@2bstudio.app.
