When you access the pages, GitHub processes technically necessary data, in particular your IP address, date and time of access, the page requested and your browser's user agent, in order to deliver the pages and keep the service secure. This may involve a transfer to the USA. GitHub is certified under the EU-US Data Privacy Framework. The legal basis is our legitimate interest in reliably providing this website (Art. 6(1)(f) GDPR).

External scripts and libraries

For display and features (e.g. syntax highlighting, graph view, interface elements), this website loads program libraries from the content delivery networks jsDelivr (cdn.jsdelivr.net, fastly.jsdelivr.net) and cdnjs (cdnjs.cloudflare.com). Your IP address is transmitted to the respective provider, which is technically necessary to deliver the files. The providers may use servers outside the EU. The legal basis is our legitimate interest in a functional and fast-loading website (Art. 6(1)(f) GDPR).

Web analytics with Umami

This website uses Umami, an open-source tool for measuring reach, which runs on our own server in Germany (stats.polyformal.de). No cookies are set, no data is stored in your browser and no IP addresses are stored.

We record the page visited, the referring page, browser, operating system, device type, screen size, language and the approximate country or region. To distinguish visits, an anonymous identifier is derived from your IP address and user agent. It changes every month and cannot be traced back to you. No data is passed on to third parties.

The legal basis is our legitimate interest in analysing how our website is used (Art. 6(1)(f) GDPR).

Opt-out: If your browser sends the "Do Not Track" signal, no data is recorded. You can enable it in your browser's privacy settings.
