1. Hair Diagnosis — zero data transmitted
Our "Personalised Hair Diagnosis" tool runs entirely in your browser using native JavaScript (Vanilla JS). Your answers to the questionnaire (hair loss type, duration, aggravating factors…) are processed locally on your device and are never transmitted, stored, or shared with our servers or any third party.
No health data is collected. As soon as you leave or reload the page, all answers are automatically erased. You retain full control over your information.
2. Anonymous statistics — Google Analytics 4
We use Google Analytics 4 to measure our site's audience and improve the quality of our content. Collected data includes:

- Country and device type (desktop, mobile, tablet)
- Traffic source (search engine, direct link, social media)
This data is anonymised (IP address truncated before any processing) and aggregated. It cannot be used to personally identify you and is never sold to third parties.
