Security & Transparency
End-to-End Encryption (E2EE)
At koalo.cc, your privacy is hard-coded. We use military-grade AES-256 encryption. Every message sent between Koalo users is encrypted on your device and can only be decrypted by the intended recipient. We never see the content of your emails.
Zero-Knowledge Architecture
We believe you shouldn't have to trust us—you should have proof. Our system is built on a zero-knowledge framework. This means we do not store your master password or your private keys. If we can't see it, we can't leak it.
No Personal Data
Your identity is your business. Registration at koalo.cc requires no phone number, no backup email, and no real name. We don't log IP addresses or track your location.
Important Transparency Note
Communication with external providers (like Gmail, Outlook, etc.) is limited by the technology they use. While your data is stored securely on our servers, once an email leaves our system to reach an external recipient, it is subject to the external provider's security standards.
