Our Commitment to Privacy
Koji a is designed with your privacy as a top priority. All video recording and emotion analysis happens directly on your device. We do not collect, store, or have access to your videos, photos, or facial data.
1. Information We Collect
We do not collect any personal information or user-generated content. The app requires access to your camera and microphone to function, but this data is processed in real-time on your device and is never sent to our servers or any third party.
2. Face and Biometric Data Policy
The application uses Apple's ARKit and Vision frameworks to detect facial features for the purpose of emotion analysis. This analysis is performed entirely on your device. The resulting facial data (such as blend shapes or landmarks) is ephemeral and is discarded immediately after analysis. We do not collect, use, share, or retain face data or any other biometric identifiers.
3. How We Use Information
Since we do not collect your information, we do not use it for any purpose. The emotion analysis data is used only to provide you with real-time feedback within the app and to create a visual timeline for your videos, which is also stored locally on your device.
4. Data Storage
All content you create with Koji, including videos, photos, and project files, is stored exclusively in the app's private storage on your device. You have full control over this data. If you delete the app, all associated data will also be deleted.
5. Your Rights
You have the right to access and delete your data at any time. Since all data is stored on your device, you can manage it directly through the app by deleting projects or individual assets.
