2. Data We Collect and Why
a) Website Analytics (DataFast)
We use DataFast, a privacy-focused analytics service, to understand how visitors use our website. DataFast operates in cookieless mode on our site:
- No cookies are set on your device
- No personally identifiable information (PII) is collected
- Visitor identifiers rotate approximately every 24 hours, preventing cross-session identification
- No device fingerprinting or cross-site tracking is performed
- Data collected includes: page views, referrer URLs, approximate geographic location (country/region level), device type, browser type, and custom engagement events (e.g., button clicks, form submissions -- without personal content)
Analytics data is proxied through jelzia.com and cannot be used to identify individual visitors. Legal basis: legitimate interest in understanding website usage to improve our services (Art. 31 para. 1 nFADP).
b) Contact Form
When you submit our contact form, we collect:
- Name
