Privacy Policy

anhnn built Collage Maker & Photo Grid as a free application. This page explains what information the app uses, why, and who it is shared with. By using the app you agree to the practices described here.

Information we do not collect

The app does not ask for or collect your name, email address, phone number, contacts or precise location. There is no registration and no user profile. The app does not use your device's advertising ID: the AD_ID permission is removed from the app.

Your photos

To let you pick photos for a collage, the app asks for permission to read the images on your device. Photos are read and edited only on your device. The app never uploads your photos, your collages or the text you type into them to anhnn or to any third party.

When you tap Save, the finished collage is written to your device's picture gallery (Pictures/CollageMaker). When you tap Share, Android's standard share sheet opens and you choose which app receives the image.

Data stored on your device

The app keeps the following on your device so it can work and remember your choices:

• Your saved projects (drafts of collages and freestyle designs), so you can open and edit them later.
• Your settings: display language, light/dark theme, export quality and format.
• Whether you have finished the welcome screens.
• Templates, fonts, frames, borders and stickers downloaded from our content server (see below), cached so they load faster.

Uninstalling the app deletes all of this data. You can also clear it at any time from your device's app settings. Images you have already saved to your gallery stay there until you delete them.

Usage statistics and crash reports

The app uses two Google services to understand how the app is used and to fix problems:

• Firebase Analytics records anonymous events such as which screens you open, which features and tools you use (for example a layout, filter, frame or font), the settings you choose and whether an export succeeded. Events do not include the contents of your photos or the text you type.
• Firebase Crashlytics sends a report when the app crashes, including the technical details of the error, your device model and Android version.

These services identify the app installation with a random Firebase installation ID and may receive your device's IP address and approximate region, general device information and how the app was installed (from Google Play's install referrer). This information is not linked to your identity and is not used for advertising. It is processed by Google under the Firebase privacy and security terms and the Google Privacy Policy, and kept only as long as Google's retention settings for these services allow.

Internet access

The app uses the internet for these purposes only:

• Downloading content. Templates, fonts, frames, borders and stickers are downloaded from the public jsDelivr content delivery network (cdn.jsdelivr.net). These are ordinary file downloads with no information about you attached, but as with any request to any website, the server can see your device's IP address. See the jsDelivr privacy policy.
• Firebase Remote Config, which lets us adjust some app settings without releasing an update.
• The usage statistics and crash reports described above.
• Showing this Privacy Policy page inside the app.

Feedback and ratings

When you send feedback from Settings, the app opens your own email app with your message filled in. Nothing is sent until you send the email yourself, and we only use your email address and message to reply to you. Rating the app opens its page on Google Play.

Permissions

• Read images / photos (READ_MEDIA_IMAGES, or READ_EXTERNAL_STORAGE on Android 12 and older): to show your photos so you can add them to a collage.
• Internet and network state: to download content and send the statistics described above.

The app requests no other permissions.

Sharing of information

We do not sell your information and do not share it with anyone other than the service providers named on this page (Google Firebase and jsDelivr), which process it only to provide their services.

Children's privacy

The app is a general-audience photo editing tool and is not directed at children under 13. We do not knowingly collect personal information from children. If you are a parent or guardian and believe your child has provided us with personal information, please contact us and we will delete it.

Your choices

• You can deny or revoke the photo permission at any time in your device's settings; you will then not be able to pick photos from the in-app gallery.
• You can delete your saved projects inside the app, or clear all app data from your device's app settings.
• You can ask us to delete any information associated with your app installation: see How to delete your data.

How to delete your data

This section applies to Collage Maker & Photo Grid (com.nnastudio.collage.maker), published by anhnn. The app has no accounts, so there is no account to delete.

Data on your device (projects, settings, downloaded content):

• Delete individual projects in the app: open the Project tab, select projects and tap Delete.
• Delete everything at once: go to your device's Settings → Apps → Collage Maker & Photo Grid → Storage → Clear storage, or uninstall the app.
• This is deleted immediately and completely. Images you already saved to your gallery are not touched; delete them from your gallery app if you wish.

Usage statistics and crash reports (held by Google Firebase):

• Email newtrust.contact@gmail.com with the subject “Collage Maker & Photo Grid — data deletion request”. We will reply within 30 days and delete the analytics and crash data that we can associate with your request.
• Because this data is not linked to your name or email, the simplest way to stop it being linked to you is to uninstall the app or clear its storage: this resets the random Firebase installation ID, so new data cannot be connected to old data.
• Whether or not you ask, this data is deleted automatically: usage statistics after at most 14 months and crash reports after 90 days. We do not keep any other copy.

We do not hold your photos, collages or any other content, so there is nothing else to delete.

Security

Data stored by the app is protected by Android's standard per-app sandbox on your device. Information sent to Firebase and jsDelivr is transmitted over encrypted (HTTPS) connections.

Changes to this policy

We may update this Privacy Policy from time to time. Any change will be posted on this page with an updated effective date.
