Privacy
The short version: this website uses no cookies, no analytics and no tracking. The app has no accounts of its own, and its banner ads are personalized only if you agree.
The Chromatic Drift app
The app doesn't ask for your name, email address, photos or location, and we run no servers that receive data from it.
- Ads: the free version shows banner ads from Google AdMob. Personalized ads are shown only with your consent. The "Remove ads" purchase removes them.
- Progress: stored on your device and, if you're signed in, in your own iCloud account so it syncs between your devices. We can't see it.
- Game Center: optional. If you're signed in, Apple handles your leaderboard score and achievements.
The full details are in the app's privacy policy:

No cookies, no analytics, no tracking
This website sets no cookies and uses no analytics or tracking tools. Every page, picture, font and script comes from this website itself. We load nothing from other companies: no web-font services, no videos, no social media buttons. Links to the App Store are plain links, and nothing is loaded from them until you click.
The playable demo on the home page runs only in your browser and saves nothing.
Hosting
This website is hosted by GitHub Pages, a service of GitHub, Inc., USA. When you open a page, GitHub's servers necessarily process your IP address and technical details of the request, such as the time, the page requested and your browser type, to deliver the page and keep the service secure. GitHub may process this data in the USA. We cannot see these logs. Details: GitHub Privacy Statement.
The legal basis is Art. 6(1)(f) GDPR: our legitimate interest in showing this website reliably and securely.
If you email us, we use your address and message only to reply, and delete them when they're no longer needed.
Your rights
Under the GDPR you can ask for access to, correction or deletion of your personal data, ask us to restrict or stop processing it, and complain to a data protection authority. Email us to use these rights.
