@pgcd @leymoo @codinghorror Nope, a session cookie is tracking. It enables processing data on you like "the same person who looked at products A, B, and C yesterday bought products C and D today". Likewise choosing what to show you based on that profiling. It might also reveal things about you to other ppl you share a computer with like "somebody using this computer was looking for information on contraceptives or HRT" etc.
Session cookies are unlawful tracking unless you consented to it by logging in to the site with the understanding and intent that you have a persistent profile and what that profile will be used for was made clear.
