What your camera roll knows about you
We take photos to remember things, and most of them stay forever. Among the sunsets and the screenshots of recipes, nearly everyone has a few pictures that would mean something to the wrong person. Here is what they usually are, why they matter more than they used to, and what to do about them.

The photos you forgot you took
The front and back of a bank card, photographed to type the number in once. A passport or ID page, taken for an application. A screenshot of a bank transfer, with your account details on it. A boarding pass, whose barcode carries your name and booking reference. The Wi-Fi card from a rental.
And sometimes a crypto wallet’s recovery phrase, saved "just for a minute". Anyone who has those words can move the funds, and nobody can reverse it.
Why it matters more than it used to
A photo used to live on one phone. With iCloud Photos turned on, it is on every device signed in to your account — the old iPad in the drawer included.
Phones also leave our hands more than we think: handed to a child, sent for repair, lost in a taxi. And a photo shared in a hurry, or added to a shared album, can carry more than you meant to send.
What to do with them
Delete what you no longer need. Deleted photos stay in Recently Deleted for 30 days, so empty it there too if you want them gone sooner.
For what you need to keep, Photos has a Hidden album, which recent versions of iOS lock behind Face ID or your passcode. Wi-Fi details and passwords belong in the Passwords app, cards in Wallet. A recovery phrase belongs on paper, somewhere safe and offline — never in a photo.
Finding them in the first place
The hard part is knowing where they are. The search in Photos reads the text in your pictures, so searching for "passport" or your bank’s name finds some of them. It cannot find what you do not know to search for, and it does not recognise a card number with no words around it. That is where a scanning app helps: it reads every photo and checks what it finds.
A photo scanner we make
Scour reads every photo on your iPhone and finds the ones holding card numbers, for free — and with Scour Pro, a one-time purchase, passports, ID cards, bank details and recovery phrases. Nothing is uploaded.
