02Hosting

This website is hosted by Vercel Inc. (340 S Lemon Ave #4133, Walnut, CA 91789, USA). When you visit the site, Vercel processes technically necessary server logs — such as your IP address, browser type (user agent) and the date and time of access. This data is needed to deliver the website and protect it against attacks. It is not combined with any other data.

03Contact form

When you submit the form on the home page, the data you enter (website address and your message) is transmitted via the Web3Forms service to our e-mail address. We use it only to answer your request — never for marketing or newsletters. The data is deleted as soon as it is no longer needed to handle your enquiry.

04Camera demo "Steer with your eyes"

The demo starts only after you explicitly activate it — before that, the camera stays off. All processing happens locally in your browser: no video is recorded, stored or transmitted anywhere. When the demo starts, your browser merely downloads the AI model file from a CDN (jsdelivr / Google storage); as with any file request, your IP address is technically transmitted in the process. As soon as you close the demo ("End" or ESC), the camera is switched off immediately.

05Motion sensors

On mobile devices, the home page may use your device's tilt (gyroscope) for a subtle parallax effect — on iOS only after your consent. This tilt data is processed exclusively in your browser and is never transmitted or stored.

06Google Fonts

The fonts on this website are loaded from Google servers (Google Fonts). When the font files are requested, your IP address is technically transmitted to Google. You can find more information in Google's privacy policy.

07Your rights

Under the Swiss Data Protection Act you have, in particular, the right to access your data as well as to have it corrected or deleted. Just write to hallo@billion.ch — we will get back to you promptly.
