Wie sieht es mit DSGVO + TTDSG + GoBD Compliance für meinen Magento Shop aus?

Berlin sits under the strictest GDPR enforcement regime in Europe. The Berlin DPA (BlnBDI) has a long track-record of high-value fines, the €746k Notebooksbilliger fine, the €14.5m Deutsche Wohnen fine, the H&M Hamburg DPA fine that originated as a Berlin complaint. So Magento DSGVO compliance in Berlin is not optional. We deploy: DSGVO, the German implementation of GDPR, with explicit consent for every non-essential cookie, DSAR automation, right-to-erasure flows, data-processing agreements (AVV) with all sub-processors. TTDSG (Telekommunikation-Telemedien-Datenschutzgesetz, 2021+), stricter than EU ePrivacy, governs cookies + tracking + fingerprinting; we deploy Cookiebot, Borlabs Cookie, or a custom Tarteaucitron banner with explicit opt-in. BDSG, the Federal Data Protection Act layered on top. GoBD, the Grundsätze zur ordnungsmäßigen Führung digitaler Bücher, which mandates 10-year tamper-proof retention of every invoice, order confirmation, and finance-related record on Magento. We implement GoBD by writing immutable invoice PDFs to an audit-log-protected S3 bucket plus a checksum table in MySQL.
