Privacy policy

Last updated 8 October 2026.

The short version

Duopress needs no account and has no server. Your photos and collages stay on your iPhone and iPad: they are never uploaded, never sent to an AI service and never seen by us. We do not sell data.

Your photos

Duopress picks photos with the system photo picker, which runs outside the app, so the app never has access to your photo library: it receives only the photos you choose. It copies them into its own storage on your device so your collages keep working, and it processes them (cutouts, filters, face-aware framing) on the device. It asks for one permission, to add a finished collage to your photo library, the first time you tap Save to Photos. Saved and shared images carry no location or camera details.

Your collages

Collages are stored in the app's own storage on your device and are included in your device's iCloud or computer backups. They are deleted only when you delete them, or when you delete the app.

Analytics and crash reports

We use Google's Firebase Analytics to count how Duopress is used (for example which tools are opened, how many photos a collage has in broad bands, whether a save went to Photos or a share sheet) and Firebase Crashlytics to receive crash reports. These carry an app instance identifier, device type and system version. They never carry your photos, anything you type, file names or image sizes tied to you.

No advertising, no tracking

Since version 1.1, Duopress shows no ads and contains no advertising software. It does not use the device advertising identifier, does not track you across other companies' apps or websites, and never asks to. Analytics collects no advertising identifier.

Purchases

Duopress Pro is bought through the App Store. We never see your payment details; the App Store tells the app only that Pro is owned. A purchase event is counted in analytics, without your identity.

Children

Duopress is not directed at children under 13 and does not knowingly collect their personal information.
