Good to know

The questions people ask most.

No. You only sign in when a prototype is private, and then only to the tool it lives in.

No. It keeps the link and a preview picture on your iPhone. That’s all.

A few: InVision (it shut down in 2024), Play and Origami Studio (those are apps, not links) and Paper. Proto tells you when you paste one of those.
