Privacy by design

Your calendar knows your life. We can't.

Your calendar knows when you see your therapist, when you interview at other companies, who you meet for lunch, and where you'll be next Tuesday. It deserves real protection.

End-to-end encrypted
Your event titles, descriptions, and locations are encrypted with keys only you hold.
On-device processing
Natural language parsing happens locally. Nothing you type is sent to a server.
No tracking or profiling
No ads, no behavioral tracking, no selling your data. You pay with money, not privacy.
Never used to train AI

Local-first architecture

Instant by design

Your calendar lives on your device first. Navigating, viewing, and editing feels instant because you're not waiting on a server for every action.

Local-first
Data on your device, not in the cloud. You own it.
Offline viewing
See your calendar without internet. Always accessible.
Instant navigation
Switch views, scroll dates. Zero lag.

Privacy & Security

Can you read my calendar?
No. Your calendar content is encrypted on your device before syncing. We store encrypted data and basic account info, but can't read your events.
What if I forget my password?
Your password generates your encryption keys. If you forget it, we can't recover your encrypted data. This is the privacy tradeoff.

Can I export my data?
Always. Export your calendars anytime as standard .ics files. Your data is never locked in - you can leave whenever you want with everything you brought.
