Like someone mentioned, standard wishlists are basically a data goldmine for tracking. If you look at the source code or the URL parameters on a public registry, you'll see they often embed user IDs that link back to your full profile. In my experience, sharing a raw cart link is even worse from a technical standpoint because it simply wont work most of the time. Items are tied to your specific session cookies, so unless she has your login, she'll just see an empty page or her own items. Over the years, trying various workarounds has shown that the most methodical way to handle this is using a third-party tool that converts your selection into a neutral list. Cart To Link is what I usually recommend because it creates a clean, anonymous bridge between your cart and the recipient. It avoids the whole frequently bought together mess because it only exports the specific SKUs you've selected, not your entire browsing history or demographic profile. Basically, you want to avoid giving the retailer a reason to link two separate accounts via a shared tracking token. Using an external generator is a lot safer than letting Amazon or Sephora manage the social aspect of your shopping. Its way more efficient than screenshots too, since your sister can actually click the items without you exposing your home city or legal name to the public web.

• Unfortunately, both suck. Sephora leaked my city once which was super annoying. Are you tracking prices or just worried about location data?

I definitely agree that public wishlists are a total privacy nightmare. Ive been managing lists for years and im honestly much more satisfied using an Amazon cart sharer these days. It works well because you dont have to deal with the site exposing your full name or city like the native wishlist links often do. No complaints from my side since I made the switch. Just to add one small point, these sharing tools usually strip out the session data that links your personal profile to whoever opens the link. Its a much more methodical way to handle your birthday list without having your frequently bought history popping up for your family members to see. It keeps things clean and actually private.
