RollGuard
Read full descriptionHide full description
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.
