HideLock

It looks like a calculator. It keeps your private files.

HideLock hides your photos, videos and files behind a working calculator. Type your PIN, press =, and your private vault opens. To everyone else, it's just a calculator.

Try it: type 1234 then = on the calculator.

Everything private, in one disguised app

HideLock is a private space inside your phone. What you put inside stays out of your gallery, file manager and recent apps.

Hide photos and videos

Move pictures and videos into the vault and they disappear from your gallery and every other album or file app.

Player and photo viewer

Watch hidden videos with brightness, volume and one-tap mute. View, crop, add filters and text to photos without leaving the vault.

Private browser

Browse without leaving history, cookies or downloads behind on your phone.

App Lock

Put a PIN or pattern on WhatsApp, Instagram or any other app so nobody can open it without you.

Cloud backup

Back up your vault so you can restore it on a new phone. Backup is optional and only runs when you turn it on.

Calculator disguise

The icon and the app look like a normal calculator, and it really calculates. Only your PIN followed by = opens the vault.

How it works

Setup takes under a minute.

  1. Set your PIN

    Open HideLock, choose a numeric PIN and a security question you'll remember.

  2. Add your files

    Pick photos, videos or files to move into the vault. They're removed from your gallery.

  3. Open with =

    Next time, type your PIN on the calculator and press = to get back in.

Back up before you uninstall

Your hidden files live inside HideLock on your phone. If you uninstall the app, clear its data, or delete the folders it creates without backing up first, those files are gone for good and we can't recover them.

Questions

The things people ask us most.

How do I open my vault?

Type your PIN on the calculator and press the = button.

I forgot my PIN. How do I reset it?

Type 11223344= on the calculator, answer your security question, and set a new PIN. If that doesn't work, tap “Trouble logging in” in the app to email us. Our team replies within 24 hours. If you don't see our reply, check your Spam or Trash folder.

Does HideLock copy or upload my photos?

No. Your files stay on your phone. They only leave your phone if you turn on cloud backup yourself.

Will my files show up in my gallery?

No. Files in the vault don't appear in your gallery, Google Photos, or file manager.

What happens if I change phones?

Turn on cloud backup on your old phone, install HideLock on the new one, and restore from backup.

Is HideLock free?

Yes. HideLock is free to download and use. If we ever offer optional paid features, the price will be shown clearly before you pay.
