Magnifier Privacy Policy

Effective 25 October 2026 · Published by Owlmakers · 한국어

Owlmakers ("the developer") operates Magnifier ("the app"). The app is a magnifier that uses the rear camera to enlarge small print and objects, and can recognise text and read it aloud.

The developer collects no personally identifying data. There is no account, no sign-up and no login, and no user data is stored on a server. The camera preview and your photos are processed on your device only. The only thing sent to a developer server is the anonymous usage statistics in section 2b.

1. Handled on your device only

DataPurposeStored where
Camera preview and photosMagnifying, taking photos, text recognitionOn your device (never sent to a server)
Photos you saveOnly photos on which you tap "Save" are keptApp-private storage (the library) and the device album (Pictures/Magnifier)
Recognised textShown on screen and used for reading aloudNot stored (screen only)
App settingsLanguage, theme and similar preferencesDevice storage
Backup file (optional)When you tap the backup button, your settings and the library list are written as a JSON file (photo files are not included)The device's Downloads folder

2. Third-party services

Google AdMob (advertising)

To show ads, Google may collect device identifiers such as the Advertising ID along with basic device and app information. Google is the party collecting and using that data; the developer does not receive it. Where required (for example in Europe), consent is collected through Google's consent tool (UMP). See the Google advertising policy. You can reset or opt out of ad personalisation in your device settings (Settings → Google → Ads).

Firebase Analytics (Google Analytics for Firebase)

To understand how the app is used, the names of actions such as screen views and button taps are sent to Google's Firebase Analytics. Photos, recognised text, and file paths are not sent. Google collects and processes that data; see the Google Privacy Policy.

Google ML Kit text recognition (on-device model)

Text recognition runs on an on-device Google ML Kit model and works offline. Recognised text is only shown on screen and is neither stored nor sent. Reading aloud is handled by the text-to-speech (TTS) engine installed on your device.

2b. Our own usage statistics (Owlmakers)

To check that the app is working in real use, the developer sends anonymous usage statistics (including country and region) to its own server (api.owlmakers.com, over HTTPS).

3. Permissions

PermissionWhen it is requestedIf you decline
CameraThe first time you open the camera screenThe camera screen cannot be used (everything else still works)
Storage writeOnly on Android 9 and below, when saving a photo to the device albumOnly the album copy is not saved
InternetShowing ads and sending usage statisticsAds do not appear; everything else works as usual

The app never asks for permissions on first launch. It asks at the moment a feature actually needs one.

Push notifications (Firebase Cloud Messaging)

This app uses Google's Firebase Cloud Messaging (FCM) to receive announcements and notices sent by the developer. When you open the app, Google assigns an FCM installation ID (registration token) to this installation; the app does not send or store this value on the developer's servers. The app subscribes to notification topics for the app name and your display language, and Google processes that subscription. A notification goes with the same content to every user of the same app and language and carries no personal data. On Android 13+ the notification permission is requested only when you tap the in-app notice line or the settings row, and you can use every other feature without allowing it. You can turn notifications off at any time in the device's Settings → Apps → Notifications, and you stop receiving them when you uninstall the app.

4. Children's privacy

The app is not directed at children under 14 and does not knowingly collect data from children.

5. Retention and deletion

Because the developer holds no personally identifying data, there is no deletion request procedure. Uninstalling the app removes the photos and settings kept in app-private storage. Copies saved to the device album and the Downloads folder remain after uninstalling, so delete them from your gallery or file app. (The only thing kept on the developer's server is the anonymous usage statistics in section 2b, deleted automatically after one year.)
