Who can see my messages?
Zangi has a very tight security system and architecture. Zangi uses end-to-end encryption, securing the entire journey of your content and metadata, from start to finish, and during transport
Only you and the recipient can see the messages and files you send to each other. Zangi does not store your messages on any servers, therefore Zangi nor other 3rd parties don’t have access to anything. That’s why when signing into another device, your messages are not transferred, because everything is serverless.

Strength of encryption:
— RSA-2048 and AES-GCM for client-server data transport encryption
— Advanced Encryption Standard (AES-256) for symmetric encryption
— Elliptic Curve (Curve25519) cryptography for authentication
— Elliptic Curve Diffie-Hellman (ECDH) for key agreement
— Secure Hash Algorithm (HMAC-SHA256) for message digest
— Customized TLS/Noise for encrypting the transport layer

And you cannot request information or messages about someone else. Zangi doesn’t not have access or any records about any user.
