Handoff

Show someone one photo on your phone — a ticket, a card, a pic — without them swiping into everything else.

Before you rely on it: Handoff locks the view and asks for your PIN to exit. It cannot block the phone's own app-switcher — someone determined can still swipe away. For that, use your phone's built-in lock (Guided Access on iOS, Screen Pinning on Android). Handoff is for the everyday "here, look at this" moment.

Your photos never leave this phone. No account, no upload, no server.
