2. Purposes and Legal Basis of Processing

We process personal data only to the extent necessary and on the following legal bases:

• Art. 6(1)(b) GDPR — Contract performance / pre-contractual measures: When you contact us via email, we process the data you provide (name, email address, message content) to respond to your inquiry.
• Art. 6(1)(f) GDPR — Legitimate interest: We have a legitimate interest in the technically secure and efficient provision of our website. For this purpose, technically necessary data is processed when you visit our website (see "Server Log Files" below).

3. Data Retention

Personal data provided by email will be retained for as long as the respective conversation requires. After the purpose has been fulfilled, the data will be deleted unless statutory retention obligations require longer storage. Server log files are deleted automatically after about 90 days (see Section 8).

4. Recipients and Processors

Your personal data will not be shared with third parties except as described below. We use the following processor: Cloudflare, Inc. — for hosting and content delivery (see Section 5). No other processors or third-party recipients are used.

5. Third-Country Transfers — Cloudflare Disclosure

This website is hosted on Cloudflare Workers (Cloudflare, Inc., 101 Townsend Street, San Francisco, CA 94107, USA). When you access this website, technically necessary data (IP address, browser type and version, time of access, requested URL, amount of data transferred) is transmitted to Cloudflare and briefly processed there for the purpose of delivering content and protecting against attacks. This processing is based on our legitimate interest in a technically secure and fast provision of our website (Art. 6(1)(f) GDPR). A data processing agreement (DPA) pursuant to Art. 28 GDPR is in place with Cloudflare. Since Cloudflare may also process data in the USA, we have concluded the EU Commission's Standard Contractual Clauses (SCC) with Cloudflare pursuant to Art. 46(2)(c) GDPR. Further information on data protection at Cloudflare can be found at https://www.cloudflare.com/privacypolicy/.

8. Server Log Files

This website is served by an edge program we operate on Cloudflare Workers. For every request it writes one log entry to Cloudflare Analytics Engine: the time of the request, hostname and path, HTTP method and response status, user-agent, referrer, coarse network location (country/network operator), and the IP address. For ordinary visitors the IP address is truncated before storage (IPv4 to /24, IPv6 to /48) so that it no longer identifies an individual device; the full IP is retained only for requests from verifiable automated crawlers (identified by their user-agent), for the purpose of verifying crawler activity. Logs are deleted automatically after about 90 days and are used solely for operating and securing the site and for aggregate, non-identifying analysis of reader and crawler access; they are not combined with other data sources. The legal basis is Art. 6(1)(f) GDPR (legitimate interest in stable and secure website operation).

9. Fonts

Fonts are served locally from the server (including the Chinese typefaces). No connection to Google Fonts or other external font CDNs takes place.

10. Cookies

This website does not use cookies and does not employ tracking technologies.

11. Contact by Email

If you contact us by email at contact@ccg-halle.de or by phone, we will process the personal data you provide solely for the purpose of handling your inquiry. The legal basis is Art. 6(1)(b) GDPR (pre-contractual measures) or Art. 6(1)(f) GDPR (legitimate interest in responding to inquiries). Your data will be deleted once the inquiry has been fully resolved, unless statutory retention obligations apply.
