A. Logs

Technical definitions first:

1. A “request” means the standard HTTP request your web browser or other client software transmits to a server for the purpose of retrieving a resource.

2. “Request information” refers to the standard HTTP request headers sent to the server by your web browser or other client software and can include the time of the request, the name of client software, your IP address, your preferred language, and other standard headers.

This website is delivered through Cloudflare and Digital Ocean with Serverpilot. These providers may collect and store your request information temporarily and use it exclusively for the purposes of delivering this website to you and to detect and block automated misuse and security issues (“malicious bot activity”).

All request information is logged and stored for up to five days, usually no more than four hours. Attempts at accessing password-protected resources or requests that are automatically identified as automated, aggressive/high-frequency, or malicious may be logged for up to five days. This information is used for aggregated statistical purposes such as identifying which web browsers or operating systems are the most popular, or which web pages are the most popular. The logs can also be used to identify and troubleshoot technical problems.
Automated software may identify and refuse service to IP addresses that are through to be unusual, disruptive, or hostile in order to protect the server and security.

The GDPR recognizes that one has a legitimate interest in maintaining security and allows data collection and processing for legitimate interests. Therefore, the reasonable retention of log files is allowed by the GDPR.

B. Cookies

The __cfduid cookie by Cloudflare is used to identify individual clients behind a shared IP address and apply security settings on a per-client basis. For example, if the visitor is in a coffee shop where there are a bunch of infected machines, but the specific visitor’s machine is trusted (e.g. because they’ve completed a challenge), the cookie allows Cloudflare to identify that client and not challenge them again. It does not correspond to any user ID, and does not store any personally identifiable information.

C. Secure communications

This site is only loaded over an encrypted connection with the server (HTTPS) providing added protection against surveillance and interference by third‐parties.

D. Analytics

This site uses Statify to measure activity. Statify doesn’t process and store personal data as e.g. IP addresses – Statify counts site views, not visitors. Due to this tracking approach, Statify is 100% compliant with GDPR.

E. How collected information is used

Personal information is only collected in the legitimate interests to protect the safety and security of visitors and to prevent illegal activities.

In some cases, there might be a legal obligation to collect personal information or there might be a need to collect personal information to protect the visitor’s vital interests or those of another person.

F. Additional notices

This site contains links to third-party websites. I have no influence whatsoever on the information on these websites and accept no guaranty for their safety. The content and safety of linked third-party sites is the responsibility of the respective owners/providers.
