App: Colla Current version: 1.0.0 Contact: diagniq.app@gmail.com
Colla is a photo collage editor for Android and iOS. Choose photos from your device, arrange them into a collage, and save or share the result. There is no account and no sign-up.
Tap Create Collage and your device’s photo picker opens. Choose the photos you want. Colla only receives the photos you pick — it does not get access to your whole photo library.
On the export screen, tap Save to Photos to write the finished collage to your device photo library, or tap Share to open your device share sheet and send it to another app.
Colla Pro unlocks premium layouts, extra backgrounds and frames, and high-resolution export. Open Pro (from the home screen or Settings) to see it. Colla Pro is a single one-time “lifetime” purchase: you pay once and it does not renew. The price is shown in your local currency before you confirm. All billing is handled by the App Store or Google Play.
The store has your request but has not charged for it yet — most often because the account uses Ask to Buy and a parent or guardian still has to approve it. Nothing went wrong. Colla Pro unlocks by itself once the purchase is approved; if it is declined, nothing is charged.
Use Restore purchase in Settings (or on the Pro screen). Make sure you are signed in to the same Apple or Google account you used for the original purchase. Restoring relies on that account’s records.
No. Colla Pro is a one-time purchase. It is not a subscription, it never renews, and you are not charged again — so there is nothing to cancel.
Refunds are handled by Apple or Google:
On your device. Colla has no account and no server. Your settings and the “Recent Creations” list stay on the device. Exported collages go into your device photo library. Uninstalling the app removes its local data; on Android you can also use Settings → Apps → Colla → Storage → Clear data. On Android, this local data is excluded from cloud backup.
The one exception is purchase data. It is processed by RevenueCat, Colla’s purchase provider, and stored in the United States. See the Privacy Policy, section 7.1.
Colla does not upload your photos. It contains no analytics or product-measurement SDK and no advertising SDK, shows no ads, and does not track you across apps or websites owned by other companies, so it never asks for tracking permission or an advertising identifier. Purchase data is the one thing the developer does receive: RevenueCat makes the purchase history recorded against each anonymous App User ID, and statistics built from it such as the number of purchases and revenue, available to the developer through its dashboard. The only network activity caused by the app is its communication with RevenueCat and the app stores. See the Privacy Policy, section 8.
