Privacy Policy

Protecting your personal data matters to us. This website is data-minimising by design: no cookies are set, no external fonts, CDNs, analytics or tracking services are loaded, and no data is shared with third parties. The German version of this policy is authoritative.

1. Controller

Kanzlei Prof. Dr. Frank Martin
Attorney at law and notary Prof. Dr. Frank Martin
Parkstraße 33, 65549 Limburg an der Lahn, Germany

2. Hosting & server log files

This website is hosted by IONOS SE, Elgendorfer Straße 57, 56410 Montabaur, Germany, on servers within the European Union, under a data-processing agreement pursuant to Art. 28 GDPR. When the pages are accessed, the server automatically collects information transmitted by your browser (server log files): browser type and version, operating system, referrer URL, time of the request and the IP address. This data is used for technical delivery, security and stability and is deleted after a short period. The legal basis is our legitimate interest in secure operation (Art. 6(1)(f) GDPR).

3. No cookies

This website does not use cookies or comparable storage techniques for marketing or analytics. A cookie banner is therefore not required.

4. Anonymous, cookieless reach measurement

To improve our offering, we record anonymously and without cookies which pages are viewed. No cookies are set and no IP addresses are stored. No attribution to an individual is possible; only aggregated, anonymous access counts are produced (using a daily-rotating, non-reversible counter). Measurement takes place solely on our own server (first-party) and transmits no data to third parties. If your browser sends the "Do Not Track" (DNT) signal, no measurement takes place at all. Legal basis: Art. 6(1)(f) GDPR.

5. Contacting us

If you contact us via the form, by email or by phone, we process the details you provide (e.g. name, email address, phone number, subject and message) solely to handle your enquiry and for any follow-up questions. Legal basis: Art. 6(1)(b) and (f) GDPR. The contact form is protected by a technical anti-spam mechanism that works without external captcha services. Your details are not shared with third parties and are deleted once they are no longer required, unless statutory retention obligations apply.

6. No external services

No third-party content is loaded automatically. In particular, no Google Fonts, no CDNs, no Google Maps, no social-media plugins and no external captcha services (hCaptcha, reCAPTCHA, Turnstile) are used. Links to external map or routing services open only after you actively click them, in a new window.

7. Your rights

  • Access to your stored data (Art. 15 GDPR),
  • Rectification of inaccurate data (Art. 16 GDPR),
  • Erasure (Art. 17 GDPR),
  • Restriction of processing (Art. 18 GDPR),
  • Data portability (Art. 20 GDPR),
  • Objection to processing (Art. 21 GDPR).

An informal message to the contact details above is sufficient to exercise your rights.

8. Right to lodge a complaint

You have the right to lodge a complaint with a data-protection supervisory authority. Responsible: the Hessian Commissioner for Data Protection and Freedom of Information (HBDI), P.O. Box 3163, 65021 Wiesbaden – datenschutz.hessen.de.

9. SSL/TLS encryption

For security reasons this site uses SSL/TLS encryption. You can recognise an encrypted connection by "https://" in your browser's address bar.
