Private by architecture, not by promise.
Privacy that depends on a policy can change. Privacy built into the math cannot.
Zero-knowledge keys
Your keys are derived on your device and never leave it. We hold ciphertext we cannot open — there is nothing to leak, sell, or surrender.
End-to-end encrypted
Mail between koalo users is sealed with AES-256-GCM before it leaves your device and opened only by the recipient. Never in between.
No tracking, no ads
No analytics, no content scanning, no tracking pixels, no ad profiles. Opening a message never pings a third party.
No identity required
No phone number, no backup email, no real name. Your IP address is never stored — you stay anonymous, even to us.
Encrypted password vault
A built-in, zero-knowledge password manager — encrypted with the same keys as your mail, included free with every inbox.
