Built to serve you, not surveil you
Three jobs.
One tool.
A desktop client that connects to your existing email, calendar, and feeds. Everything runs on your machine.
1
Your data,
your computer.
Lose your laptop, lose nothing. One locked file. One password. No cloud, no tracking, no us in the middle.
2
End-to-end,
between Gratins.
Two Gratin users, any two providers, full end-to-end encryption. Your IMAP server stores ciphertext it can't read. No new address, no migration, no "secure messaging" silo — just regular email that happens to be unreadable to everyone except the recipient.
3
Three apps,
one window.
Stop tab-juggling. Email, calendar, news feeds, and contacts — one window, keyboard shortcuts, fast search.
