Description

Arcanum is an encrypted container manager for Android that creates and mounts VeraCrypt-compatible volumes. Your files are protected with military-grade encryption and remain accessible only to you.

<b>Key Features</b>

• VeraCrypt-compatible — containers work on desktop too (Windows, macOS, Linux)
• AES-256, Twofish, Serpent and cascade ciphers
• Multiple hash algorithms: SHA-512, SHA-256, Whirlpool, Streebog, BLAKE2s-256
• Hidden volumes for plausible deniability
• Keyfile support
• Biometric unlock (fingerprint / face)

<b>Privacy &amp; Security</b>

• Disguise mode — app appears as a plain calculator on the home screen
• Panic PIN — instantly wipes sensitive data and resets the app
• Auto-lock when the app goes to the background
• PIN protected with Argon2id key derivation
• No network access, no analytics, no telemetry
• All data stays on your device

<b>Open Source</b>

Arcanum is fully open source. The cryptographic implementation is based on the VeraCrypt codebase. You can review, audit, and build the app yourself.

This is the F-Droid build: all features are included, no payments required.
