This Privacy Policy describes how 禮貌相機 - 我就問，你禮貌嗎？ ("the App", "we", "us") handles your information. We are committed to protecting your privacy.
The App uses your device camera solely to provide real-time visual effects (e.g., mosaic overlays). Camera frames are processed entirely on-device and are never stored, uploaded, or transmitted to any server or third party.
The App uses Google MediaPipe, an on-device machine learning framework, to detect faces and hand gestures. All detection runs locally on your device using ML model files bundled within the App. No facial images, face landmarks, biometric data, or any camera-derived data ever leaves your device.
Face and hand detection data exists only in memory for the duration of a single camera frame (milliseconds) and is immediately discarded after rendering the visual effect. We do not collect, store, or retain any face data.
The App displays advertisements provided by Google AdMob (Google LLC). Google AdMob may collect and use data such as advertising identifiers, device information, and usage data to serve personalized or non-personalized ads. This data collection is governed by Google's Privacy Policy: https://policies.google.com/privacy.
You may remove all advertisements by purchasing the "移除廣告 (Remove Ads)" in-app purchase. After purchase, Google AdMob will no longer be active in the App.
The App offers an optional one-time in-app purchase to remove advertisements. All purchases are processed by Apple through the App Store. We do not collect or store any payment information.
We do not collect analytics or usage data directly. Third-party SDKs (e.g., Google AdMob) may collect anonymized usage and diagnostic data as described in their respective privacy policies.
We do not retain any personal data. Camera and face detection data is processed in real-time and immediately discarded. We have no servers that store user data.
The App does not knowingly collect personal information from children under 13. If you believe a child has provided personal information, please contact us so we can take appropriate action.
We may update this Privacy Policy from time to time. Any changes will be reflected on this page with an updated date. Continued use of the App after changes constitutes acceptance of the new policy.
