Muntin puts two to nine of your photos together into one picture: a layout made for that many, each photo framed in its cell, and the shape, spacing, border, corners and background you choose. We do not create accounts, do not ask for your email, and do not ship any analytics or tracking SDK. Your photos stay on your phone. Muntin keeps its own copies of the photos in your collage in progress, in its private storage, until you start a new collage, and never sends them anywhere. A picture leaves the phone only if you save it or share it.
Muntin has no photo-library, storage, camera or location permission. Photos come through Android’s own photo picker, which hands the app only the pictures you chose. Every collage is drawn on the phone, so making one never uses the internet. The app contains no code that can reach a server at all, apart from the advertising SDK described below, which receives nothing from your photos.
If that’s all you wanted to know, you’re done. The sections below spell it out in detail.
com.dashfusion.listcollage)The following is created and kept locally, in the app’s private storage:
How long they stay: your collage in progress and the copies of its photos stay until you start a new collage (Muntin asks first) or uninstall the app. A photo you take out of the collage, or replace with another, keeps its copy until the app next starts or you start a new collage, so that its Undo always has the photo to put back; at those moments the app removes every copy the collage no longer uses.
The app explicitly opts out of Android cloud backup and device-to-device transfer, so Android never copies your collage or its photos to Google Drive or to another phone. A new phone starts with no collage in progress; the pictures you saved are in your gallery, where your own backup finds them.
We have no servers and no cloud storage. We cannot see your photos or your collages, and we cannot recover them if you lose your device.
The app contains the Google Mobile Ads SDK. It shows an occasional full-screen interstitial ad — only after you have saved or shared a collage, once the app has said where it went, never while you are making a collage and never as the app opens — plus an optional rewarded ad you can choose to watch to remove ads for 24 hours. There are no banner ads. Google may collect and process:
AdMob receives nothing from your collages: no photo, no layout, no keyword and no content URL. Like any ad in any app, an ad request does name the app it comes from. The approximate location above is Google’s estimate from your internet address; it is never your phone’s location, which Muntin cannot read. Google’s handling of the data above is governed by Google’s own policies:
Consent (EEA, UK and Switzerland): on first launch the app shows Google’s certified consent form, and you choose whether personalised ads are allowed. You can change your answer at any time from Settings → Advert privacy options inside the app. You can also opt out of personalised advertising via your device’s system settings (Android: Settings → Privacy → Ads).
None. We don’t run any backend. We have no analytics SDK, no crash reporter that phones home, no Firebase, and no custom telemetry. There is no HTTP client anywhere in the app’s own code, and the build fails if one is ever added.
AD_ID) — required by Google Play for apps that serve ads; used by
AdMob as described above.That is all of them. Muntin asks for no permission at runtime: Android never stops to ask you about one. It has no access to your location — no GPS, no fine or approximate location, no background location — and none to your camera, photo library, media, files, contacts, messages, calendar or microphone, and it asks for none of them. It sends no notifications and asks for no notification permission.
A few more permissions are merged into the final app package by the libraries the app is built on, so the list Google Play shows you is slightly longer than the one above. They are the Android Ad Services permissions, from the Google Mobile Ads SDK; wake-lock and foreground-service, from the Android scheduling library the ads SDK brings in; and one permission that only lets the app’s own parts talk to each other. None is a permission Android stops to ask you about, and none is used by any code we wrote: Muntin holds no wake lock and runs no foreground service of its own. A test reads the built app’s own merged manifest on every run and fails the build if that list ever changes, or if any location, camera, storage or media permission appears in it.
Muntin is a tool for adults who put their own photos together into one picture, and is intended for adults. It is not directed to children under 13, and we do not knowingly collect data from children — and, as above, we collect no personal data from anyone.
If we change the data we collect or the third-party services we integrate, we will update this page and bump the “Last updated” date above. Material changes will be flagged in the app’s release notes as well.
