Encryption & Security

When you send a message on Rackon, your device encrypts it using a key that only you and your recipient have. The encrypted message passes through Rackon's servers, but since the server never has the decryption key, it can't read anything. On the other end, your recipient's device uses their private key to decrypt and display the message.

The result is that your conversation stays between you and the person you're talking to. No one else in the chain can read it.

Rackon uses AES (Advanced Encryption Standard). It's the same encryption standard relied upon by financial institutions, government agencies, and defense organizations around the world. It's widely regarded as one of the most robust encryption methods available today.

AES is considered extremely strong by current cryptographic standards. The mathematics behind it make a brute-force attack computationally infeasible with today's technology — the time required would far exceed any practical capability. While no encryption can come with an absolute guarantee against future advances, AES is the closest thing to a gold standard in modern encryption.

Even in the event of a server breach, the damage would be extremely limited. Rackon's servers only ever hold encrypted data and public keys, neither of which is useful to an attacker without the corresponding private keys, which never leave your device. There are no plaintext messages, no decryption keys, and no readable data for an attacker to access.

This is one of the practical advantages of zero-knowledge architecture: a compromised server doesn't mean compromised conversations.

Group messages in Rackon are encrypted individually for each member of the group. This means every participant receives their own uniquely encrypted copy of the message, and no group member can decrypt another member's copy. The same AES standard that protects one-on-one messages applies to every group conversation.

No. Rackon does not share your data with any third parties, not advertisers, not data brokers, not partners. Your data stays with you.

No. Rackon doesn't log metadata about your conversations — meaning we don't record who you're messaging, how often, or when. This is a meaningful privacy distinction, since many apps that claim to protect message content still collect detailed metadata about communication patterns.

Zero-knowledge encryption refers to a system architecture in which the service provider stores or transmits data in a form they can never read or decrypt — even if compelled to. It ensures that privacy is guaranteed by design, not just by policy.

Rackon doesn't store unencrypted messages, and the encryption keys are never held on our servers. Because we don't have the keys, we have no ability to decrypt your messages — regardless of circumstances. Privacy isn't a setting you turn on; it's built into the system itself.
