Privacy Policy
This English version is a reference translation. The Japanese version is authoritative.
VRC Power Translation (the "App") transcribes and translates, on your smartphone (iPhone or Android), audio received from a PC you have paired. There is no user account.
1. On-device processing
Speech recognition and translation run on models on your device. The App does not send conversation audio or text to cloud speech-recognition or translation services. Transcripts and translations are shown on the device and sent to the PC you connected over Wi-Fi/LAN, USB or Bluetooth LE. How the PC displays, stores or forwards them follows the PC's settings. Please respect the consent of the people you talk with and the rules of the place where you use the App.
2. Data stored on the device
- To connect, the App stores the PC identifier, PC name, a random identifier generated by the App, the PC addresses and the pairing information. The pairing secret is kept in the iOS Keychain (this device only, available while unlocked) on iPhone, and encrypted with the device Keystore on Android.
- Language and display settings, tutorial progress and downloaded models are stored in the App's storage. On iPhone, downloaded models are excluded from iCloud backup. On Android, OS backup and device transfer may apply to some settings.
- Audio buffers and the on-screen conversation history are kept in memory and are not saved.
3. Model downloads
Additional models are downloaded over HTTPS from GitHub and its content delivery services, which receive your IP address, the requested file and connection details. Model downloads never include conversation audio or text.
4. Camera and device permissions
iPhone: Local Network permission is used to communicate with the PC, Camera permission to read the QR code shown on the PC, and Bluetooth permission only when you choose the Bluetooth LE connection. QR images and results are processed on the device only and are not sent anywhere. The App does not request microphone, location, contacts or photo access.
Android: Bluetooth permission is used for the Bluetooth LE connection and notification permission to keep the connection and show download status. The App itself does not request microphone, camera, location or contacts access. QR codes are read with Google Code Scanner (Google Play services); images are processed on the device and, according to Google, images and results are not stored by Google. Google's SDK may send model updates and diagnostic information (device model, OS and app information, installation identifiers, usage events, performance and errors) to Google. See Google's SDK data disclosure and the Google Privacy Policy.
5. Advertising and analytics
The App contains no advertising, analytics or tracking SDKs (for the Google SDK used for QR scanning on Android, see section 4). We do not sell personal information or use it for advertising. The operator does not receive your usage data or conversation content.
6. Network security
Not all conversation traffic on the local network is encrypted. Use a PC and network you trust.
7. Deletion
You can remove pairing information from the connection screen and unused models from the model screen. Deleting the App removes its local data (on iPhone a pairing secret may remain in the Keychain; on Android you can also clear the app storage in Settings). Delete records on the PC separately. Data held by GitHub and other providers follows their own policies.
8. Changes
We may change this policy as features or laws change. When we do, we update the effective date on this page and announce it on our official X account.
9. Operator and contact
The operator is Yumi Hironaka, an individual and the developer's guardian (the address is disclosed without delay upon request).
