Privacy Policy

Last updated: May 2026

mmagnifier is a magnification app for people with low vision. We take privacy seriously. We collect nothing and transmit nothing.

Camera

mmagnifier uses your device's rear camera to display a live magnified view on screen. No video or images are recorded, stored, or transmitted anywhere. The camera is active only while the app is open and in the foreground. On the web version, the camera stream is released as soon as you switch away from the tab.

Flashlight

The torch is available in the native Android app only. It activates only when you tap the Torch button and turns off when you tap it again or close the app. It is never activated automatically.

Local storage

mmagnifier saves your zoom level, color mode, and brightness preference to your device's local storage. This data stays on your device only and is never transmitted anywhere.

Read text aloud

The native app includes an optional "Read" feature that scans the frozen camera frame for text and reads it aloud. Text recognition is performed entirely on your device using Google's ML Kit (Android). No image or text is sent to any server. Speech is produced by the device's built-in text-to-speech engine; no audio is recorded or transmitted.

What we don't do

• Collect any personal information
• Use analytics, crash reporting, or tracking of any kind
• Show advertisements
• Send your camera feed, images, or recognized text anywhere
• Share any data with third parties
• Require an account or login

Permissions

The Android app declares four permissions:

• Camera: required for live magnification
• Flashlight: required for the torch button
• Internet and network state: declared by Google's on-device text recognition library, which uses them to fetch its language model from Google Play once, on first install. The app itself makes no network requests, and your camera images and recognized text are never transmitted.

Camera is the only permission you are ever asked to approve. Text recognition and text-to-speech run on device using built-in system capabilities.
