Privacy Policy
Effective date: August 22, 20261. Overview
Signer ("the app") is an American Sign Language fingerspelling app developed by Bilal Naeem. This Privacy Policy explains what information the app accesses, how it is used, and what we do not do with it.
2. Camera Access
Signer requests access to your device camera solely to detect hand signs in real time. Camera frames are:
- Processed entirely on your device using Apple Vision and Core ML
- Never saved to your photo library or any file
- Never transmitted over the internet or to any server
- Discarded immediately after each inference pass
Camera access is required for the app's core functionality. You can revoke it at any time in Settings → Privacy & Security → Camera.
3. No Data Collection
Signer does not collect:
- Personal information (name, email, phone number, etc.)
- Location data
- Usage analytics or telemetry
- Device identifiers or advertising IDs
- Crash reports sent to third-party services
4. No Third-Party SDKs
Signer does not include any third-party analytics, advertising, or tracking libraries. All machine learning models are bundled locally and run on-device using Apple's Core ML framework.
5. On-Device Processing
Sign detection, hand pose estimation, speech synthesis, and all other features operate entirely on your iPhone or iPad. No internet connection is required for any core feature of the app.
6. User Settings
Your in-app preferences (confidence threshold, speech settings, mask color, etc.) are saved locally to your device using iOS UserDefaults. This data never leaves your device.
7. Children's Privacy
Signer does not knowingly collect any information from children or any other users. Because no data is collected at all, the app is safe for users of any age.
8. Changes to This Policy
If this policy changes, the updated version will be posted at this URL with a revised effective date. Continued use of the app after any changes constitutes acceptance of the new policy.
