Calculator Vault - SecretSum

SecretSum works as both a Standard and Scientific Calculator. When the correct PIN is entered, a Hidden Space (Secret Vault) unlocks where you can safely hide your private photos and videos. In addition to hiding media, SecretSum also provides useful features such as secure notes, video player, camera, wallpapers, browser, and recycle bin. SecretSum keeps your private files stored securely and allows access only after entering the correct digital PIN. If the correct PIN is not entered, the app works like a normal calculator and performs calculations. 🆕 What's New in Version 2 • Added Password Recovery system (Security Question & Email Verification) • Improved security (Prevent reuse of old password) • Added Banner, Native & Interstitial Ads • Fixed calculator bugs (Plus/Minus button issue) • Added calculation history saving • Performance improvements and bug fixes Main features 🧮 Standard & Scientific Calculator •Supports Standard and Scientific calculator modes •Perform basic operations: addition, subtraction, multiplication & division •Advanced scientific functions like sin, cos, tan, log, square root, power •Fast and accurate calculations •Clean and easy-to-use calculator interface •Works smoothly like a real calculator •Calculator works normally while keeping vault hidden 🖼️ Hide Images & Videos •Securely hide your private images and videos •Hidden media files will not appear in gallery or file manager •Access hidden images and videos only after entering correct PIN •Keep personal media safe from unauthorized access •Easy to hide and unhide files anytime 🖼️ Built-in Photo Viewer & Editor • View hidden photos directly inside the calculator • Edit photos without restoring them to gallery • Basic editing tools available: ° Crop images ° Rotate photos ° Add text on images • Additional basic features similar to system gallery. 🎥 Built-in Video Player • Watch hidden videos directly inside the calculator • Control brightness and volume easily 📝 Notes Section • Save personal and secret notes securely • Add, edit, and delete notes easily • Perfect for storing private information safely 📷 In-App Camera • Click photos directly inside the calculator • Images are automatically saved in the hidden vault • No need to use the system camera 🌐 In-App Browser • Secure browsing experience • History saved locally (can be deleted anytime) • Download images and videos • Keeps browsing private 🔐 Password Recovery • Recover password using Security Question or Email Verification • Secure reset system to regain access ❓ FAQs 🔐 How to open the Secret Vault?
