A normal YouTube embed loads scripts and sets cookies from youtube.com and doubleclick.net as soon as the page is opened.
Even in “enhanced privacy mode” (youtube-nocookie.com), data is transmitted to Google (USA) when Play is clicked; on a plain page view the mode is more data-minimising but not free of connections. For non-necessary access, § 25 (1) TDDDG applies.
The free scan checks the delivered HTML and shows which services are embedded, whether a cookie banner is detected and whether privacy-policy and legal-notice links are present — with context for each finding. It is not a substitute for legal advice.
