Description
Calculator Vault – Private Photo & File Locker Behind a Real Calculator
Calculator Vault is more than just a simple calculator — it's a secure and discreet vault for your private photos, videos, notes, and files. Hidden behind a fully functional calculator interface, this app allows you to protect your sensitive content with a secure PIN password while maintaining complete privacy and disguise.
Whether you're looking for a photo vault, video locker, notes hider, or document protector, Calculator Vault offers a seamless solution with military-grade encryption and real-time security features — all under the appearance of a regular calculator.
Vault Calculator – Disguised & Secure The app’s interface functions like a real calculator, making it the perfect disguise. Simply enter your secret PIN to access your hidden content. This intelligent design helps prevent unwanted access and keeps your private data secure at all times. Photo & Video Vault – Keep Moments Private Hide your personal photos and videos securely inside the vault. Calculator Vault encrypts and stores your media files away from the public gallery, ensuring privacy with zero compromise. Perfect for protecting sensitive media and keeping private memories away from prying eyes. Notes Locker – Protect Personal Information Secure your private notes in a personal digital locker. Whether it's sensitive information, passwords, or thoughts, your notes are stored safely and are accessible only through your secret PIN. Intruder Selfie – Stay Notified of Unauthorized Attempts If someone tries to access your vault with the wrong PIN, the app automatically captures their photo using the front camera. This adds an extra layer of protection and alerts you to any unauthorized access attempts. Document & File Locker – Total File Protection Hide important documents, PDFs, and other files securely inside the app. Ideal for users who want to protect work-related files or personal documents in a private, encrypted vault. Icon Camouflage – Stay Hidden in Plain Sight The app icon and interface perfectly mimic a standard calculator, allowing it to blend into your device without drawing attention. This stealth feature ensures that your privacy remains protected without suspicion. All-in-One Vault for Total Privacy From locking photos and videos to securing documents and notes, Calculator Vault combines multiple layers of security in one powerful app. Whether you're looking for a photo vault, secret calculator, or file locker, this app ensures privacy, simplicity, and peace of mind. Why We Require "All Files Access" (Android 11+) Calculator Vault requires "All Files Access" (MANAGE_EXTERNAL_STORAGE) permission on Android 11 and above to perform its essential functions — hiding and restoring photos, videos, documents, and files from any folder on your device. This permission enables the app to move files to a private location and later restore them to their original path as per your command.
Your data always stays on your device and is never uploaded or shared without your explicit consent. Important User Notes: 1. Calculator Vault does not collect or share any personal data. 2. The app functions entirely offline, keeping your files fully private. 3. Deleted files are unrecoverable — ensure you back up any important data. 4. Uninstalling the app without restoring your files will result in permanent loss.
Recent changes: ✔ Quickly hide photos and videos ✔ Multiple calculator icons added ✔ Enhanced user privacy settings ✔ Secure more files without any size limit ✔ Updated user interface ✔ Minor bug fixes

The first screen when you open the app is the advertisement to go pro, so all the secrecy of the app is blowed away. It should appear once you enter the pin code and enter the vault.
