Privacy Policy
Transparency, minimalism, and cookieless privacy on rfc10023.de
1. Responsible Entity / Data Controller
The data controller within the meaning of the General Data Protection Regulation (GDPR) and other data protection regulations is the operator of this website. For full contact information, please refer to the Imprint.
2. Zero External CDNs (Zero-CDN Architecture)
This website does not load external web fonts (e.g. Google Fonts) or remote CDN JavaScript/CSS libraries. Only native system fonts installed locally on your operating system are rendered. This strictly eliminates the unauthorized transmission of visitor IP addresses to third-party servers in non-EU countries during page loads.
3. Vercel Web Analytics (Cookieless Metrics)
This website utilizes Vercel Web Analytics, provided by Vercel Inc., 340 S Lemon Ave #4133, Walnut, CA 91789, USA.
Vercel Web Analytics is designed to operate without cookies, aims not to create individual user profiles, and is intended not to store personal data permanently. To measure anonymous page views and optimize loading times, an ephemeral, irreversible hash is generated that prevents identification of your individual person or device. IP addresses are not stored persistently.
The legal basis is our legitimate interest in the technically stable, secure, and needs-oriented provision of our informational service in accordance with Art. 6 (1) lit. f GDPR.
4. Live DNS-over-HTTPS (DoH) Validator, Bulk Scanner & API
When verifying a domain via our live validator or bulk scanner, DNS lookups run over HTTPS (DoH) directly from your client browser to public anycast resolvers provided by Cloudflare Inc. or Google LLC. Only publicly queried DNS records (_for-sale.[domain]) are retrieved. We do not store your inspected domains or submitted portfolio lists on our servers, nor do we create user profiles.
5. Server Log Files
When accessing this website, our hosting provider (Vercel) automatically logs standard technical connection data (server logs), including browser user-agent, operating system, referrer URL, and timestamp. This data is not assignable to specific individuals and serves solely to ensure technical operation and denial-of-service defense.
6. Your Rights as a Data Subject
Under applicable data protection laws, you have the right at any time to free information regarding your stored personal data, its origin and recipients, and the right to rectification or erasure. For any inquiries regarding personal data and privacy, you may contact us at any time via the address specified in the Imprint.
