Do guests really only ever see their own photos? That's the selling point for me, but it sounds too good.

It's genuinely the core design, not a marketing afterthought. Each guest's access is scoped to the photos matched to their selfie — they don't get a browse-all view, and the albums themselves are private, unindexed and never exposed publicly. Snaptide's whole privacy pitch rests on this: "guests can only view photos matched to them." The one exception is the separate full-access link with a secret token, which you'd only hand to a host or organizer who genuinely needs to see everything. Everyone else stays in their own lane.
