Your connection to langrock.info and it's sub-sites is end-to-end encrypted using HTTPS.
As I utilize Cloudflare's HTTP proxy, all requests sent to langrock.info will be proxied through Cloudflare. Both the connection between you and Cloudflare as well as Cloudflare and langrock.info's host use strict HTTPS connections.
Additionally, the HSTS (HTTP Strict Transport Security) headers are sent to ensure your browser will always use said HTTPS connection.
When you browse this website and it's sub-sites, every request is logged. This does not mean that langrock.info knows who you are, what your name is or what you recently bought. All logging happens server-side and your browser does not send any more data than it needs to.
Cloudflare, a service I use to, among other things, boost the sites performance and block bad people or bots, plants a small cookie on your computer to enhance the site's security. What are cookies?
This means that, in case there is an attack on the website or if some other user on your network looks suspicious, Cloudflare knows that you are a legitimate user and will let you through while the attackers get blocked. Cloudflare does not track individual users across the web and collects as little data as possible. More details can be found in Cloudflare's article.
You might have noticed that there is no cookie popup or GDPR banner on here. This is because the above mentioned cookie is essential for providing the service and does not allow cross-site tracking. These kinds of essential cookies do not require an annoying banner.
Logging takes place through the third party Cloudflare App Logflare.
The collected data is stored in Logflare's BigQuery table for 7 days, after which it gets permanently deleted.
