Calculator Vault: Hide Photos

Looking like a perfectly normal calculator is the point. Secret Calculator is a private photo vault and secure file locker disguised as a fully functional calculator app. Type your secret code and unlock a hidden private space where your most personal content stays protected from anyone else.

Your privacy, hidden in plain sight

Secret Calculator looks and works exactly like a real calculator. Anyone who picks up your phone sees a standard calculator with no suspicious icon, no vault label, and no indication that anything private is stored inside. Only you know that entering your personal PIN reveals a hidden vault for your photos, videos, audio files, documents, and notes.

How it works

Open the app and use it as a real calculator whenever you want. When you need your private vault, type your secret PIN and press equals. The calculator disappears and your private gallery opens. Simple, seamless, and discreet.

What you can protect

Photos and albums: import images directly from your gallery into encrypted private photo albums, organized and accessible only to you. Create multiple albums and keep them completely hidden from your regular photo library.

Videos: store personal video files and sensitive recordings safely away from anyone who should not see them. Your private videos stay inside the vault, invisible to your device gallery.

Audio files: protect private voice recordings and personal audio content behind your secret code. No one else can access your audio.

Documents and PDFs: keep sensitive files, scanned documents, identification papers, and confidential paperwork private and accessible only to you. No one else can view your documents.

Encrypted notes: write and store personal notes, private thoughts, and sensitive information with complete privacy protection. Secured inside the vault alongside your other files.

Your data never leaves your device

Everything stays on your phone. Secret Calculator does not upload your files to any server, does not sync to the cloud, and does not share your content with any third party. Your private photos, videos, and files are physically stored on your device alone, protected by your secret code.

No remote access. No server storage. No data collection.

Built to stay hidden

The app icon looks exactly like a standard calculator. The interface functions as a real, working calculator. If someone picks up your phone and opens the app, they see only a calculator. Entering the wrong code produces only a calculator result. No suspicious app name. No lock icon. No indication of any private content stored inside.

Who uses Secret Calculator

Secret Calculator is used by anyone who wants a private space on their phone. Parents who share devices with children. Professionals carrying sensitive documents alongside personal files. Partners who want their own private space on a shared device. Anyone who prefers to keep certain photos, notes, or files to themselves. Privacy is a normal need, and Secret Calculator makes it effortless.

Secure trash bin with recovery window

Deleted files do not disappear immediately. The built-in trash bin holds removed content for 7 days before permanent deletion, giving you a safety window to recover anything deleted by accident.

Simple setup, immediate privacy

Setting up Secret Calculator takes under one minute. Choose your secret PIN code, import your files, and your private vault is ready. No account registration required. No email address needed. No personal information collected during setup.

Secret Calculator is built for anyone who values personal privacy. Whether you are protecting sensitive documents, private photos, personal notes, or confidential files, Secret Calculator keeps everything invisible inside a perfectly ordinary-looking calculator.

Your files. Your device. Your privacy.
