Privacy Policy

Last updated: July 10, 2026

ShutterLab is an iPhone app for screening film camera shutter timing. This policy explains what the app accesses, stores, and does not collect.

Microphone access

ShutterLab uses the microphone only after you start a measurement. Audio is processed on device to detect shutter transients. Cognerva does not receive, upload, or store microphone recordings from the app.

Saved measurements

The app stores camera labels, nominal and measured timing, sensor mode, analysis values, and timestamps in local app storage. These records are not synced to Cognerva. If you export CSV data, iOS lets you choose where and how to share it.

No accounts, analytics, ads, or tracking

ShutterLab requires no account and includes no advertising, analytics, or third-party tracking SDKs. Cognerva does not collect personal data through the app.

Your control

Stop microphone access by ending the measurement.
Revoke microphone permission in iOS Settings.
Delete individual local measurements in the app.
Deleting ShutterLab removes its local app data from the device.
