koalo.ccEnd-to-end encrypted · Zero-knowledge
Truly private email.
Every message is encrypted on your device before it leaves. koalo stores ciphertext it cannot open - no ads, no scanning, no phone number, no IP logs.
Free · Ready in under a minute · No personal data required
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.

Thinking of switching?
How koalo compares to the inbox you have today.
Standard for encrypted mail · three of four
End-to-end encrypted by default
No ads, no content scanning
Gmail has neither. Consumer accounts get no end-to-end encryption, and ads still run in the inbox tabs. Proton and Tuta match koalo on both.
Not universal · two of four
Sign-up without phone or personal data
Gmail's skip option is not guaranteed and is unavailable on desktop. Proton asks for no phone but usually runs another check. Tuta asks for nothing.
Every feature included, free
Proton and Tuta cap free accounts at 1 GB with no custom domain. Gmail's free tier is the one that fails the two claims above.
Only koalo · one of four
Zero-knowledge password vault inside the mail app
Proton ships one as a separate app, free tier included. Tuta has none. Google's lives in the browser, not the mailbox.
No imports, no migration wizard, no lock-in. Start fresh with an address that is actually yours.
