Projection Mapping for Android · Last updated: 10 November 2026

Short version: Projection Mapping has no accounts and contains no advertising, analytics or tracking libraries. The app does not ask for internet access, so it cannot send anything from your device. Your projects, photos, videos and recordings stay on your device. The developer does not receive any of your data.

Microphone

The microphone is optional. The app asks for it only when you turn on motion that follows sound (bass, mid, treble or volume). While such a setting is active, the app listens through the microphone and measures how loud the sound is, in memory and in real time, so the visuals can move with the music. The sound is not recorded, not saved and not sent anywhere. You can refuse the permission and use everything else, and you can take the permission back at any time in Android Settings.

Photos and videos you choose

When you add a photo or a video, you pick it in Android's own file picker. The app can read only the files you picked. It reads them on the device to show them inside your shapes. They are not copied to any server. The project remembers a link to each file so it can open it again later.

Projects

Your projects (shapes, scenes, settings and a small preview picture) are saved in the app's private storage on your device. They are removed when you delete the project, clear the app's storage or uninstall the app.

Recordings

When you record your show, the app saves a video of the visuals to the Movies folder of your device, in a folder named Projection Mapping. The recording contains no sound. It is an ordinary file on your device that you can share or delete yourself.

Projector and second screen

The picture is shown on the display you connect, by cable or as a wireless display, through Android's own display features. The app does not send the picture anywhere else.

Device backup

If backup is turned on in your Android settings, Android may include the app's project files in the backup of your own Google account. That backup is made by Android and is controlled in your device settings. The developer has no access to it.

Reporting a problem

"Report a problem" opens your email app with a draft that contains the app version, the Android version and the device model, so a problem can be found faster. You can edit or delete these lines. Nothing is sent unless you send the email yourself. Emails you send are used only to answer you and to fix the problem.

Other services

The app contains no advertising, no analytics and no crash reporting service, and it shares no data with anyone. If you install it from Google Play, Google handles the download and updates under its own privacy policy.

Children

The app is a tool for people who use a projector. It is not directed at children under 13, and it does not collect personal information from anyone.

Changes

If this policy changes, the new version will be published on this page with a new date.
