About this app

Bit Secure Offline is a 100% offline, Zero-Knowledge cryptocurrency asset storage vault engineered to keep your secret keys, seed phrases, and crypto credentials completely isolated from the internet.

KEY SECURITY & PRIVACY FEATURES:

• 100% Offline & Zero Network Permissions
The app explicitly removes all network permissions (INTERNET, ACCESS_NETWORK_STATE, ACCESS_WIFI_STATE). Your sensitive crypto data never touches a server, cloud network, or third-party service.

• Zero-Knowledge E2EE Encryption
All stored data is encrypted locally using military-grade AES-256-GCM encryption paired with PBKDF2 key derivation. Your private data is unsealed exclusively inside volatile device memory (RAM).

• Dual Authentication Protection
Secure your vault with a combination of a custom Numeric PIN (0-9) and Android OS pattern / biometric authentication for robust local access defense.

• 5-Minute Auto-Lock Defense
To prevent unauthorized physical access if your device is left unattended, the app automatically locks after 5 minutes of background inactivity.

• Total User Sovereignty & No Trackers
Contains zero analytics, zero ads, zero tracking SDKs, and zero third-party code. You retain 100% control over your offline cryptographic backups.

Protect your digital wealth with uncompromised, air-gapped security.
