Registration data is permanently stored exclusively in EU data centers (via Cloudflare R2). Processing may occur in Cloudflare's global network for performance optimization. Cloudflare has signed a GDPR-compliant Data Processing Agreement (DPA) with us and maintains appropriate technical and organizational measures to protect your data.
