Privacy Policy

Witness for Android · Application ID com.mmsstudio.witness
Effective 9 September 2026 · Last updated 9 September 2026

The short version. Witness has no account, no server and no analytics. Your video, audio and location never leave your phone. We — the developer — cannot see any of it, because none of it is ever sent anywhere.

1. Who this covers

This policy applies to the Witness Android application published by MMS Studio (“we”, “us”). It explains what the app records, where that stays, and what it never does. It applies to the app only, not to any other software on your device.

2. Information we collect

We collect nothing. Witness does not have user accounts, does not contact any server operated by us, and contains no analytics, advertising or crash-reporting service. There is no mechanism in the app by which your recordings, location or usage could reach us.

3. What the app records, and where it stays

Witness necessarily records a great deal in order to function as a dashcam. All of it is written to your device and stays there.

WhatWhyWhere it is stored
Video from the rear camera, and the front camera if you enable itThe recording itselfThe app’s private storage on your device
Audio from the microphone, if you leave audio recording onRecorded into the video fileInside the video files, in the app’s private storage
Location and speed from GPSShown while driving, drawn into the footage, and used to decide whether you are over the limitDrawn into the video frames, and in a small metadata file beside each clip
Accelerometer readingsDetecting an impact so the clip can be locked against being overwrittenProcessed as it arrives; only the peak value is saved beside the clip
The identifier of the Bluetooth device you choose as a triggerSo recording can start when your car connectsApp settings on your device

Driver-assistance analysis — collision, following distance, lane departure and reading speed limit signs — runs entirely on your device using models bundled inside the app. Camera frames used for it are examined and discarded immediately; they are not saved separately and not transmitted.

4. What we never do

5. Permissions, and why each is needed

Android will ask for these. You can refuse or later withdraw any of them in your device settings; features that depend on a refused permission simply stop working.

PermissionWhat it is for
CameraRecording the road, and the cabin if you enable the front camera.
MicrophoneRecording audio into the clip. Optional — you can turn it off.
Location (including in the background)Speed and coordinates shown on screen and drawn into the footage. Background access is what keeps this working once the screen turns off, which is the normal state of a dashcam while you drive.
Nearby devices / BluetoothNoticing that the car you chose has connected, so recording can start on its own. Used only to recognise that one device.
NotificationsThe ongoing notification Android requires while recording.
Ignore battery optimisationsWithout it Android stops the recording shortly after the screen locks, which is precisely when a dashcam must keep going.
Display over other appsBringing the recorder to the front when your car connects. Android will not let a backgrounded app use the camera, so without this an automatic start can produce an empty file. Optional.
Start at bootResuming the loop after the phone restarts while docked.

6. Third-party components

Witness is built with Google libraries — ML Kit, MediaPipe and TensorFlow Lite — that perform the on-device vision work. Their models are bundled inside the app and run locally; the app does not download models and works with no connection at all.

Witness itself does not declare internet access. Some of these Google libraries do, and they may send their own diagnostic or usage information to Google independently of anything we control. That processing is governed by Google’s Privacy Policy, not by this one. We receive nothing from it.

7. Keeping and deleting your recordings

Recordings loop: once the storage you allocated is full, the oldest unlocked clip is overwritten by the newest. Clips locked by an impact, or locked by you, are never overwritten automatically — you delete those yourself.

Everything in the app’s private storage is deleted when you uninstall Witness or clear its data. Clips you explicitly save to your gallery are copied into your device’s shared Movies folder and are not removed by uninstalling — they belong to your device’s media library, and you delete them as you would any other video.

8. Children

Witness is a tool for drivers and is not directed at children. We do not knowingly collect information from anyone — of any age — because we do not collect information at all.

9. Your rights

Rights to access, correct, export or erase personal data apply to data a company holds about you. We hold none. Everything Witness records is in your possession on your own device, and you can view, export or delete it at any time from within the app or your device’s file and gallery apps.

10. Changes to this policy

If this policy changes, the updated version will be posted at this address with a new “last updated” date. Material changes will be noted in the app’s release notes on Google Play.
