Privacy

Voluntarily submitted data

The expert-brief form stores the work email, declared topic and free-text context submitted by the user.

Purpose: qualify the request and prepare a relevant response or introduction. Legal basis: your consent and the legitimate interest in handling a contact request (Art. 6 GDPR).

Retention: expert-brief requests are kept for at most 12 months after the last exchange, then deleted or anonymized.

Audience measurement

The site uses GoatCounter, a cookieless analytics tool with no personal identifier (page views, referrer host and three aggregated key events).

Legal basis: legitimate interest in privacy-friendly audience measurement. No personal data, no profiling and no cross-site correlation.

Advertising (Google AdSense)

Google AdSense advertising loads only after your explicit consent. Refusing is as easy as accepting and no ad is served until you accept.

Legal basis: your consent (Art. 6.1.a GDPR), revocable at any time via “Manage ad preferences” in the footer. Processor: Google Ireland Ltd.

Processors and transfers

Processors: Google Ireland Ltd (AdSense), the hosting infrastructure managed by the publisher and the transactional email service.

Any transfer outside the EU relies on the European Commission's Standard Contractual Clauses.
