NimbleCal week view - your private calendar
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

Google, Apple, and Microsoft calendars are free because you're the product. NimbleCal flips the model.

  • Your data is never used to train AI

  • On-device natural language input
  • Keyboard-first for power users
  • Local-first = instant, not sluggish
  • Works fully offline
  • Actively developed, not abandonware

Frequently Asked Questions

Is there a free plan?

Can you read my calendar?
No. Your calendar content is encrypted on your device before syncing. We store encrypted data but can't read your events.
Can I import my existing calendar?
Yes. NimbleCal uses the iCalendar standard (.ics files) - the same format used by Google Calendar, Apple Calendar, and Outlook. Import your events in seconds.
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.
Does it work offline?
Yes. Offline access and editing are included. Your changes sync automatically when you're back online.
What platforms are supported?
The web app works best on desktop browsers. Mobile browsers work for basic viewing, but features like reminders aren't reliable due to platform limitations. iOS and Android apps are in development to deliver a proper mobile experience.
What's your refund policy?
30-day money-back guarantee on your first payment, no questions asked.
