AES-256 encrypted vault for photos, videos, notes, and messages hidden inside a fully functional calculator app for iOS.
Calc+ Vault is a privacy-focused iOS application that provides an encrypted vault for storing photos, videos, notes, documents, and private messages. The app disguises itself as a fully functional calculator; users enter a PIN on the calculator keypad and tap '=' to access their vault. It uses AES-256-GCM encryption, stores keys in the iOS Keychain, and offers features such as end-to-end encrypted messaging, VoIP calls, a private browser, per-folder PIN locks, iCloud sync, and biometric unlock (Face ID/Touch ID). The free tier includes limited storage, while Pro and Ultimate subscriptions unlock unlimited storage, encrypted messaging, outbound calls/SMS, and more. No account is required, and data never leaves the device unencrypted.
