Definition

A GDPR-compliant website fulfills all requirements of the EU General Data Protection Regulation: transparent data processing, informed consent from users, technical and organizational protective measures and enforceable data subject rights at all times.

At a Glance

The 12 mandatory building blocks of a GDPR-compliant website

  1. SSL/TLS encryption — HTTPS for all pages, HSTS header set
  2. Privacy policy — complete, current, easy to understand, in German
  3. Imprint with GDPR-relevant information — including data protection officer
  4. Cookie consent — opt-in, granular, documented, revocable
  5. Data processing agreements (DPA) — for hosting, analytics, newsletter
  6. Data subject rights — access, rectification, erasure, data portability
  7. Data minimization — Only collect what is really necessary
  8. Privacy by Design / by Default — Default settings data protection friendly
  9. Server location in EU or adequate data protection level — no US hosting without SCC
  10. Deletion concept — automated deletion periods for all data categories
  11. Data protection impact assessment (DPIA) — for high-risk processing
  12. Data protection officer — appointed, accessible, independent

How mekyn.com automatically fulfills 10 of 12 building blocks

mekyn websites are static-first and cookieless — this eliminates the most complex GDPR building blocks:

  • No cookie banner needed: Plausible Analytics does not collect personal data — no opt-in required
  • No data processors except hosting: Hosting at Hetzner (DE), CDN at Cloudflare (with EU standard contractual clauses)
  • Automatic deletion concept: Form data is deleted after 30 days, server logs after 7 days
  • Privacy by Design: No tracking IDs, no fingerprinting, no third-party cookies

The remaining two building blocks — imprint and data protection officer — are the operator’s responsibility.

The biggest GDPR mistakes we see

  1. Google Fonts from CDN: Every page load sends the user’s IP to Google servers in the US. Self-host fonts as .woff2 files.
  2. YouTube embeds without privacy mode: YouTube sets tracking cookies. Use youtube-nocookie.com or lazy-load after consent.
  3. Google Analytics without consent: GA4 is still personal data processing. Use cookieless alternatives or get explicit consent.
  4. Missing data processing agreements: Every service that processes user data needs a DPA. Hosting, email, analytics — all of it.
  5. Privacy policy copied from competitors: Copyright violation plus potentially wrong information. Write your own or use a generator.

Server location: Why it matters

The server location determines which jurisdiction applies. For GDPR compliance:

  • EU servers: GDPR applies directly. No additional measures needed.
  • US servers: Schrems II ruling invalidated Privacy Shield. Standard Contractual Clauses (SCC) required, plus additional technical measures.
  • Other third countries: Adequacy decision by EU Commission required, or SCC + technical measures.

mekyn hosting is exclusively in Germany (Hetzner) with Cloudflare CDN (EU data centers for European customers). This eliminates the Schrems II problem entirely.

When you need a data protection officer

A data protection officer is mandatory under GDPR Art. 37 when:

  • Public authority: Government agencies always need one.
  • Systematic monitoring: Core business involves regular, systematic monitoring of individuals (e.g., tracking, profiling).
  • Special categories: Core business involves processing sensitive data (health, religion, political views) on a large scale.
  • 20+ employees: In Germany, companies with 20+ employees involved in automated data processing typically need one.

For most SMEs with a simple marketing website, a data protection officer is not mandatory — but having an external consultant on call is good practice.
