Privacy

ROS-Ready is a personal, non-commercial project. It sets no cookies, shows no ads and has no accounts. Nothing you type in the course or the playground is uploaded.

Your progress

Points, ranks, finished chapters and your ROS 1 / ROS 2 choice are saved in your own browser (local storage) so they are still there next time. They never leave your device. Clearing your browser data, or “Obliviate” in the playground journal, deletes them.

The playground

The Spell Terminal is a simulation that runs entirely in your browser; it does not execute anything on a server. The Potions Lab runs Python in your browser with Pyodide. Only when you start the lab, your browser downloads Pyodide from the jsDelivr CDN, which, like any server you connect to, sees your IP address. Your code stays in your browser.

Anonymous visitor statistics

To see how many people use the course and which chapters they read, this site uses Umami, an open-source analytics tool that runs on my own server. It counts page views together with the referring site, browser, operating system, device type, screen size, language and the approximate location (country, region, city) derived from the IP address. Your IP address itself is not stored, no cookies are set, and you are not tracked across other websites. The data is not shared with anyone.

Hosting

The site runs on a server rented from IONOS SE in Germany. To deliver pages, the server necessarily processes technical connection data such as your IP address; it does not keep request logs.
