Find the sensitive photos hiding in your camera roll before someone else does. RollGuard scans your photos for passports, driver's licenses, national ID cards, payment cards — including card backs — screenshots of passwords and credentials, photographed WiFi and router labels, and other private images — entirely on your iPhone. It even scans in Airplane Mode — proof that nothing is uploaded, nothing is analyzed in the cloud. There's no account to create. Review what's flagged, then keep, hide, or delete — you're always the one who decides. RollGuard finds identity documents wherever they're hiding in your camera roll — passports, national ID cards, driving licenses, health and tax documents, residence permits — built and tested against real specimen documents from 180 countries and territories, in more than 30 languages. It doesn't just spot things that look like documents: passports and modern ID cards from any country are read and checked against their own machine-readable rules, and anything it can't verify is still flagged for you to decide. Passports from 100 MRZ-verified states have checked out against their own check digits in testing. Deep coverage for Australia, New Zealand, the UK, Ireland, Canada and the US, broad coverage across Europe — and growing. Before you hand over your work phone. IT prepping a device for return, or handing one back yourself — a fast scan flags anything private that shouldn't travel with the hardware. Before you sell or trade it in. Old passwords, screenshotted 2FA codes, a photo of your license from years ago — RollGuard finds what a factory reset alone won't help you notice before it's gone for good. Before you hand your phone to family. Kids playing games, family scrolling through photos — a quick pass first means nothing private turns up by accident. Before you travel. A lighter camera roll for border crossings and unfamiliar hands. Or just a spring clean. "What's actually in my thousands of photos?" — most people genuinely don't know. Find out what's hidden in there. RollGuard's free tier does more than a typical free trial: it runs a genuinely complete scan of your last 30 days — every category, every action, no artificial limits inside that window, re-scannable anytime — with the full review queue included: real thumbnails, tap to zoom, and keep, hide, or delete, all free. It also keeps going: working through the rest of your library on its own, showing you a real running count of what's flagged out there. Pro unlocks the review queue for everything beyond your last 30 days — without it, finding a specific older flagged photo yourself would mean scrolling through thousands of images by hand; Pro does that for you. One-time purchase, forever: no subscription, no recurring charges, ever. RollGuard also flags possibly sensitive images using Apple's own on-device detection, following your iPhone's Sensitive Content Warning setting — nothing about those images ever leaves your phone either. RollGuard never tells you your library is "safe." It flags what it finds for your review — you make every call.
