HideU: Calculator Lock

HideU: Calculator Lock is a security app designed to help you conceal photos, videos, and other private files inside a calculator-style interface. Instead of opening a typical lock screen, you create a secret space using a four-digit code. When you open it again, you’ll only see a working calculator—type four digits and tap the "=" button to enter your hidden vault.

Highlights

Strong protection

There are plenty of reasons to use a dedicated protection tool—and HideU focuses on keeping your private content out of view.

• Hard to spot: Protected items are concealed behind a camouflage layer, helping ensure strangers can’t easily find what’s inside.

Watch in the app

You can enjoy videos directly without leaving the app.

Smart viewing adjustments

The app includes player-style features so you can browse different types of content more easily.

Edit your media

You can crop images or apply filters to the content you want to update.

Key Features

• Hide photos & videos

  Secret media stored in HideU won’t appear in other photo albums, galleries, or file managers. Keep your private pictures and movies safely inside the built-in vault.

• Video player & built-in photo viewer

  Play hidden videos within the calculator lock. The video player includes handy controls to quickly adjust brightness, sound, and use one-tap mute when needed.

  

  With the built-in Photo Viewer, you can browse hidden photos inside HideU. The app also supports editing, including filters, cropping, text, and basic adjustments—similar to standard system photo editing.

• Private browser

  If you want to protect your browsing history, the private browser offers a more secret and anonymous way to browse.

• App lock

  For apps you lock, others must enter a password or draw the unlock pattern to access them. This helps prevent your privacy from being exposed to other people.

• Cloud service

  Back up your personal files and data to the cloud in a safe and private way, helping maximize your data protection.

• Icon disguise

  The app icon resembles a regular system calculator, and you can even use it for calculations. Unlocking the calculator’s private space also requires a secret input method—so only you know it exists.

Why It’s Useful

Modern smartphones come with capable cameras, so people capture photos and videos more than ever. Since media can build up quickly, it’s easy to lose track—especially of the files you’d rather keep private. HideU: Calculator Lock acts like a media vault disguised as a calculator, letting you store photos, videos, and even other items like documents or text files.

A key benefit is that anything you store inside won’t show up in other places on your device, helping keep your content secure.

It also offers the option to lock apps inside the vault, which can be especially helpful for messengers, dialers, or file managers. Note: the app is free and may include ads, which can feel disruptive when you switch between apps or open your storage.

The purpose of the private space is known only to you, helping keep your personal vault effectively protected.
