Embedded Content

Some pages may con­tain em­bed­ded con­tent (videos, im­ages, etc.) from other web­sites. Embedded con­tent from other web­sites be­haves in the ex­act same way as if you had vis­ited the other web­site. These web­sites may col­lect data about you, use cook­ies, em­bed ad­di­tional third-party track­ing, and mon­i­tor your in­ter­ac­tion with that em­bed­ded con­tent, in­clud­ing track­ing your in­ter­ac­tion with the em­bed­ded con­tent if you have an ac­count and are logged into that web­site.

Because this is the case, I only dis­play em­bed­ded con­tent with your spe­cific con­sent. I don’t re­mem­ber what choice you make.
