The productivity suite that can't read your data.
Mail, calendar, tasks, and notes in one account — encrypted on your device before it ever leaves. Self-host it or let us run it.

Don't take our word for it — read the code yourself.
Security
We literally can't
read your data.
Every note, task, event, and email is encrypted on your device with AGE before it leaves. The data key is sealed with your password and backup phrase — so the version that reaches our servers is gibberish, and only you can ever turn it back.
- No backdoor
- No recovery by us
- Your password is the only key*
*Your recovery keys can also decrypt your data — keep them somewhere safe.

Sealed with your key before it leaves. We can't open it.

Sign up free in under a minute — no credit card. You get 100 MB of encrypted storage to start, across mail, calendar, tasks and notes.
Start using it right away
Your apps work in the browser and on desktop and mobile. Everything is encrypted on your device automatically — there is nothing to configure.
Stay, scale, or self-host
Add storage as you grow, or take the open-source code and run the whole suite on your own infrastructure. You are never locked in.
No compromises
Privacy that doesn't
cost you features.
Every feature you'd expect from a modern productivity suite — encrypted from end to end, always.
End-to-end encrypted

Run the full suite on your own infrastructure. Your data never has to leave your servers.
Built on Go microservices
A lean backend with no bloat — fast to run, simple to operate, easy to scale.
Fully open source
Licensed under AGPLv3. Read the code, audit the encryption, fork it, or contribute. No black boxes — the entire stack is public.
Honest pricing
A flat service fee and metered storage. No per-seat pricing, no surprises.
