A private calculator that hides photos, videos and files. Secure browsing.
Calculator Vault looks and works like a normal calculator. But behind the calculator keypad, there is a private space for your photos, videos, and files — plus a browser that leaves no history. What You Can Do Hide Photos and Videos Import photos and videos from your gallery into your private vault. After importing, the original copies are removed from your gallery, so they won’t show up in your normal photo apps or when someone browses your device. Hide Files Store personal documents, receipts, or any sensitive files in the vault. Open them anytime from inside the vault without exposing them in your file manager. Incognito Browser Browse websites without saving history, cookies, or cache. You can also download images from the web directly into your vault. When you close the browser, no browsing data is left on your device. How to Open the Vault The app icon and interface look like a standard calculator. To open your private space, type your secret number code on the calculator keypad and press the “=” button. If someone else opens the app, they will only see a working calculator. About the Secret Code There is no separate PIN screen or account login. The code is entered directly on the calculator keypad, which is what makes the disguise work. Choose a number combination that you and the people you trust can remember. Because the code is entered like a normal calculation, it does not look suspicious to anyone watching. Privacy Design Your hidden content stays on your device. The app does not upload your photos, videos, or files to any server. No account is required. Frequently Asked Questions How do I open the vault? Type your secret number code on the calculator screen and tap “=”. The vault will open. What if I forget the code? The code is not stored in a recoverable form. If you forget it, you may lose access to the hidden content. Please choose a code you will remember, or keep it somewhere safe outside the app. Are my files backed up online? No. Files are stored only on your device. Uninstalling the app will remove all hidden content permanently. Back up your files before uninstalling or switching phones. Can I recover files if I uninstall the app? No. Once the app is uninstalled, the vault and everything inside are deleted. There is no cloud backup or recovery option. Important Notes This app does not lock other apps on your phone. This app does not hide itself from Android settings or the app list. Hidden files are stored in the app’s private storage area and are not accessible from your regular gallery or file manager. The secret code is entered on the calculator keypad. There is no separate PIN screen.
