About VOID – Offline Encryption

With VOID, you can:

• Encrypt your texts securely and offline.
VOID uses AES-256 encryption to ensure your information is protected with military-grade security.
All encryption and decryption happen locally on your device — your data never leaves your phone.
No cloud storage, no internet connection, no third-party servers.
Your privacy is guaranteed because your information stay completely offline.

• Customize encryption parameters.
Take full control of how your data is secured.
With VOID, you can fine-tune encryption settings including salt length (0–256 bytes), number of iterations (up to 500), memory usage (up to 1024 MiB), parallelism (up to 6 threads), and key length (up to 224 bytes).
You can even apply up to 7 layers of encryption for maximum security.
This flexibility allows advanced users to optimize encryption strength according to their needs.

• Use a hidden key (VOID Secret).
VOID Secret is a unique hidden key variant generated per device.
Each device can generate up to 999 different hidden keys, providing an extra layer of protection.
Only you can decrypt messages with the correct VOID Secret, ensuring your communication remains fully confidential even if the main password is shared.
The hidden key is optional, but it offers an additional level of security for sensitive conversations.

• Encode your texts in emoji.
Transform your messages into emoji sequences for fun.
VOID converts your text to Base64 and then into emojis, allowing you to send encrypted messages that look like playful strings of symbols.
This feature not only adds a layer of secrecy but also makes the encryption process visually engaging.

Additional Features:
Offline-first design: VOID never connects to the internet, stores, or transmits your data.
No accounts or registration: No personal information is ever required.
Temporary decryption timer: Set a self-expiring timer so messages can only be decrypted within a limited time.
Multilingual support: Use VOID comfortably in your preferred language.
Intuitive UI/UX: Designed with Apple’s guidelines in mind, including animations, haptic feedback, and simple, elegant navigation.
With VOID, your information is not only encrypted — it is under your full control.
You decide how, when, and with whom to share them.

Secrets truly stay secret.
