Lock files on your iPhone, of any type
Locked keeps files of any type, such as PDFs, scanned documents, exports and archives, in an encrypted vault on your iPhone or iPad. Import them from the Files app. Each file is encrypted with its own random 256-bit key before it is saved, stored under a random name, and opens only inside Locked, after your pattern or password.
Which files can Locked keep?
Any type. Copies of ID cards and passports, contracts, medical letters, tax documents, exported chats, archives. Import them from the Files app, where they can come from iCloud Drive, another app or a USB drive.
What does encrypted mean for a file in Locked?
The file’s contents are encrypted with AES-256-GCM, in chunks, with a key made just for that file. On disk it has a random name and padded size, and no header that says it is a PDF or anything else. Its real name lives only in the vault’s encrypted index.
So someone who copies the app’s files sees neither what you keep nor what it is called.
Can I give someone a file safely?
With Locked Pro, Send a copy packs items into one encrypted file that you share any way you like. It opens only with its own 12 words, which you pass on separately. Locked never receives it.
How many files can I keep?
Without Locked Pro, 10 files, shared across every vault on the device. Locked Pro has no limit on items.
Questions
Can I open a PDF without taking it out of Locked?
Yes. Files open inside Locked, in the vault.
Is the file name hidden too?
Yes. On disk every file has a random name; the real one is kept only in the vault’s encrypted index.
