HideX APK — Calculator Photo Vault, App Lock & App Hider

The description of HideX APK — Calculator Photo Vault, App Lock & App Hider

HideX APK looks like a plain calculator sitting on your home screen, but type your PIN into it and a hidden vault opens up for your private photos, videos and apps. Nobody who picks up your phone sees anything but a calculator. That is the whole idea, and it works well for keeping casual snoopers out. The file on this page is scanned for malware and installed on a real Android device by our editors before publishing, we have done this since 2018.

It is a privacy tool, not a game, so there are no coins or levels here. What you get is a simple way to lock things away and hide them in plain sight.

What is HideX?

HideX is a privacy vault app from Flatfish Studio. On the surface it behaves like a working calculator, so it blends in with the rest of your utilities. Enter the right code and it switches into a private area where you can stash photos, videos and whole apps you would rather keep off the main screen.

The app crossed 100 million installs while it was on the store, and it stays light on resources, so even an older phone runs it fine. Setup takes a minute: you pick a PIN, and that PIN becomes the key to everything you hide.

Key features

There is also a video downloader tucked into the app. It may pull clips from some sites, but results depend on the source, so treat it as a bonus rather than a promise. The core of HideX is the vault and the disguise, and those are what it does best.

How the disguise works (and its limits)

The calculator front is clever, but be honest with yourself about what it protects against. The icon says calculator, and access sits behind your code, so a friend, a kid or a nosy coworker who grabs your phone sees nothing. For everyday privacy, that is usually enough.

What it is not is bank-grade encryption. If a phone is rooted, seized, or handed to someone technical, your hidden files can potentially be reached through the file system. And keep your PIN safe, because there is no cloud recovery by default, so a forgotten code can mean losing what you locked away. Use HideX for peace of mind, not as your only line of defense for anything truly sensitive.

Availability & where to get it

Here is the part most listings get wrong. HideX was pulled from Google Play back in 2021, so you won't find it in the official store anymore, no matter how carefully you search. The app itself still works fine on current Android, it just isn't distributed through Play.

That means the only way to install it now is through a sideloaded APK, which is exactly why the source matters. The build on this page is checked before it goes live, so you are not gambling on a random mirror. Grab it here and skip the sketchy download sites.

How to download and install

The download is a small APK, around 32 MB, and it runs on Android 4.4 and up. The whole thing takes a couple of minutes.

1. Tap the Download APK button on this page, the file comes down directly, no sign-up or SMS.
2. Allow installs from unknown sources for your browser or file manager (Settings → Security).
3. Open the file and tap Install, then let it finish.
4. Launch HideX, set a PIN you'll remember, and start moving your private photos, videos and apps into the vault.

Tips & privacy notes

• Set a PIN that isn't your phone unlock code or a birthday, a repeated or obvious number defeats the point.
• Turn on Intruder Snapshot so you get a face shot if someone tries the wrong code.
• Don't lean on the vault as your only protection for truly sensitive files, pair it with your phone's own screen lock.
• Back up anything important somewhere separate, since there is no default cloud recovery if you forget the PIN.
• Browse more privacy and utility apps in the catalog, or check the MOD section if you want modified builds of other tools.
