Secure Folder is your personal vault to lock and hide private photos, videos, contacts, notes, passwords, and more behind Face ID, Touch ID, or a secure PIN. All in a clean, elegant, and easy-to-use interface. Whether it’s family memories, confidential documents, or sensitive contacts, Secure Folder keeps your personal content truly private. Everything stays on your device or in your private iCloud, never on our servers. Powerful Protection: - Lock the entire app with Face ID / Touch ID / PIN - Lock specific albums or folders with their own PINs - Fake Passcode (Optional): Set up a separate passcode to unlock a secondary vault.
