This site has no accounts, no comments and no newsletter. It does not ask for your name or your e-mail.
When you follow a link to a video from one of my notes, the link passes through a short address that counts the click and remembers which note you came from. That is all it records: no name, no e-mail, nothing typed.
The pages use the ordinary server logs that every website keeps and a small counter that notes which parts of a page were read. Nothing here is sold or shared, and nothing is used for advertising.
If you want to ask something or have a note corrected, the address is on the About page.
