Real situations, step by step
Underlock is a private vault for your iPhone. Each page takes one situation: what to do, and what Underlock does.
Someone knows your passcode
Give private photos a lock your passcode doesn’t open.
Showing one photo
Show one photo without handing over your camera roll.
Asking someone to take your photo
Hand over a locked iPhone, with only the camera open.
Photos meant for one person
Keep these photos in a vault that opens with a pattern you draw.
A shared iPad or Mac
Keep private photos off the family iPad or Mac.
Medical and progress photos
Before-and-after shots and medical photos, in a vault of their own.
Your health records
Your records, Apple’s Health app, and what HIPAA doesn’t cover.
Photos you’re not ready to look at
Keep the photos, and stop your iPhone showing them.
Keeping a surprise
Gift ideas and plans, out of sight until the day.
IDs and documents
Photos of your ID and passport, out of your camera roll.
Immigration papers
What USCIS and IRCC say to carry, and where to keep copies.
Caring for a parent
A parent’s IDs and medical papers, in a folder of their own.
Work and personal photos
Keep work photos and personal photos apart, each with its own pattern.
When kids or family use your phone
Let them play or scroll without seeing what’s private.
Sending your iPhone for repair
Get your iPhone ready, with private photos in a vault your passcode doesn’t open.
A lost or stolen iPhone
What to do first, and why your passcode doesn’t open your vault.
Trouble with a landlord
Photos when you move in and out, your lease, and who to ask.
When debt collectors keep contacting you
Your rights, what to keep, and how to complain.
Harassment at work: your records
What to write down, and what the agencies say about deadlines.
Going through a divorce
Papers to gather and copies to keep, from the courts’ own pages.
When someone threatens to share your photos
Who to tell first, and what the FBI says to do.
When someone checks or controls your phone
Safety comes first: what to know, and where to get help.
When police ask to see your phone
What courts and governments say, and who to ask about your case.
At a border, or when an official asks
Underlock doesn’t change what an official can ask you to open.
Private photos stay private. And stay yours.
