OV message

FULL DESCRIPTION :
OV Message is a messaging application designed to provide a high level of privacy. Your messages are encrypted before being sent and can only be read by you and your recipient.
The application works without an Internet connection and without any intermediary server. Your data stays on your device.

END-TO-END ENCRYPTION
Each conversation has its own unique encryption key to ensure the confidentiality of your messages. The encryption uses an advanced protocol with integrity verification. Even if your messages are intercepted, their content remains unreadable without the key.

UNIVERSAL ENCRYPTION
OV Message includes an encryption module that allows you to manually encrypt and decrypt messages. You can copy an encrypted message and send it via any platform: WhatsApp, Telegram, email, or any other means of communication. Encryption is not limited to a single channel.

NO DEPENDENCIES
No account to create. No number to verify online. No server to trust. OV Message works autonomously on your device, without relying on any company or external infrastructure.

PANIC MODE
Under duress, panic mode instantly erases all your data to protect your privacy. Complete destruction in less than 2 seconds.

EPHEMERAL MESSAGES
Set up automatic deletion of your messages: 5 minutes, 30 minutes, 1 hour, 6 hours, 1 day, 1 week, or 1 month. Messages are deleted from the application and the phone.

SECURE SHARING
Encrypted messages can be shared as QR codes, enabling secure exchange without going through a digital channel. Encryption keys can also be exported and stored on a physical medium such as a paper document.

KEY MANAGEMENT
Generate, exchange, and manage your encryption keys with ease. Each contact has their own unique key. Exchange your keys in person via QR code for maximum security.
