Privacy Policy

Kolor is a photo editor and collage maker for iPhone and iPad. This policy explains what the app does with your photos and your data. The short version is simple: Kolor has no server, and twofox collects nothing.

1. Who we are

Kolor is made and published by Nischal Khadka, an independent developer, under the name twofox. For anything about this policy, write to support@twofox.app.

2. What we collect

Nothing. The app does not ask you to create an account, does not collect your name, email address or contact details, does not record how you use it, and contains no analytics, crash-reporting or advertising software from anyone. Kolor makes no network requests at all; it works exactly the same in airplane mode.

3. What stays on your device

• Projects, saved as .pxsproj bundles: a small JSON manifest describing your layers and edits, plus your untouched source images. An edit never overwrites an original.
• Imported photos, copied into the project when you pick them, so the project keeps working even if you later delete the photo from your library.
• Brushes, presets and settings, including export format and quality, appearance, and haptics.

Deleting a project removes its bundle. Deleting the app removes all of it.

4. Photos and camera

• Picking photos: Kolor uses the system photo picker, which hands over only the photos you choose. The app never sees, scans or indexes the rest of your library, and needs no library permission to pick.
• Saving exports: the first time you save an image to Photos, iOS asks for add-only permission. Kolor can then add images to your library but cannot read it.
• Camera: if you tap the camera button to capture a photo straight into a project, iOS asks for camera permission. Kolor shows the live preview and keeps the frame you take; nothing is recorded or stored otherwise.

5. Photo metadata

Photos can carry metadata such as the capture date, camera model and, if you had location on when you took them, where you were. By default Kolor strips this metadata from exported images. The Keep photo metadata switch on the export sheet copies the source photo's metadata into the export instead; use it only when you want that information to travel with the image.

6. On-device analysis

Some tools look at the picture to help you: the retouch tools use Apple's Vision framework to find facial landmarks, such as pupils, so that eye and skin adjustments land in the right place, and cutout tools compare colours to build a selection. All of this runs on your device with Apple's classical, non-generative detectors. Nothing is generated, nothing is sent anywhere, and no result of this analysis is stored beyond the edit you make.

7. What Kolor never does

• No account, sign-in or email list.
• No analytics, crash reporting or advertising identifiers.
• No generative AI and no cloud inference. Every edit is computed on your device.
• No selling or sharing of anything, because nothing is collected.

8. Deleting your data

• One project: delete it from the Studio grid; its bundle and the copies of your source photos go with it.
• Everything: delete the app. iOS removes its private storage. Images you exported to Photos are yours and stay in Photos.

9. Children

Kolor collects nothing from anyone, contains no in-app purchases, no ads and no social features, and is rated for all ages on the App Store.

10. Your rights

Privacy laws such as the GDPR, the CCPA and the Maryland Online Data Privacy Act give you rights to access, correct, delete or export personal data a company holds about you. twofox holds no personal data about Kolor users, so every one of those rights is satisfied by the controls on your own device described above. If you believe we have got any of this wrong, write to us and we will answer.

11. Changes to this policy

If this policy changes, the new version appears here with a new date, and material changes are noted in the app's release notes. We will never quietly start collecting data under an old policy.
