About
SudoVault is a fully functional professional Sudoku game with a built-in private photo vault and file safe. Professional Sudoku Six difficulty levels: Easy, Medium, Hard, Expert, Master, and Hell. Each difficulty has independent level progression. Smart hints powered by a solver engine provide exact answers, not random guesses. Notes mode lets you mark candidate numbers to assist logical solving. Every completed game is automatically saved as a record, allowing you to review historical boards at any time. Timer and statistics track your best times and error rates independently across all six difficulties. Private Photo Vault and File Safe Import and securely store your photos and videos. Import files from other apps into your private space with built-in QuickLook preview, supporting direct viewing of PDFs, Office documents, images, videos, and more. Import contacts from your device address book, with all contact information stored locally. All data is kept solely on your device and is never uploaded to any server or cloud service. Multiple Layers of Security Password protection with Face ID or Touch ID biometric authentication. Set a destruct password to instantly wipe all private space data from the password screen in an emergency. Intrusion detection silently captures a photo using the front camera when the wrong password is entered a specified number of times, recording potential intruders. Privacy protection features: cover the Dynamic Island to instantly switch back to Sudoku, shake your phone to exit the vault, or use the movable floating button for quick exit. The app automatically leaves the private space when entering the background.
