What the app collects

Nothing about you. CT Atlas has no accounts, no sign-in, no analytics, no advertising and no tracking. It does not ask for your name, email, location, contacts, photos or any other personal information.

What stays on your device

The cases you open and whether you have bought CT Atlas Pro are stored on your device only, so that the app works without a network. Uninstalling the app removes them.

Downloads

Some cases are downloaded when you first open them, from this website, which is hosted by Cloudflare. As with any website, Cloudflare processes the technical data needed to deliver the files (such as your IP address) under its own privacy policy. We do not receive or keep these data.

Purchases

CT Atlas Pro is sold through Google Play or the App Store. Payment is handled entirely by them under their own privacy policies; we never see your payment details.

The CT images

The scans in the app come from a public, anonymised research dataset (TotalSegmentator CT dataset, licensed under CC BY 4.0). They contain no names or other identifying information, and the face and the skin of the head were removed from every case that shows the head. No images from users are collected or processed.

Children

The app collects no personal information from anyone, including children.
