Two references to 'youtube,com' should be 'youtube.com'.

Under the section "How do we store your data?", the line, "...we will delete your data by remove it from our servers...", would be better English if it read, "...by removing it..."

The section "How to manage your cookies?" has the line, "You can set your browser not to accept cookies, and the above website tells you how to remove cookies from your browser."
