Calendar privacy on Mac: local-first vs third-party accounts
Where your calendar data lives determines how private it is. A local-first app built on Apple EventKit keeps events in your own system apps and iCloud, without a third-party account or tracking.
Key takeaways
- Local-first means your events and tasks stay in Apple's apps and your iCloud.
- EventKit avoids creating a third-party account that holds a copy of your data.
- Kopit Cal has no account, no analytics, and no tracking.
The question is where your data lives
Calendar privacy comes down to a simple question: who holds your data. Many calendar apps ask you to sign in to their own service, which means a copy of your schedule sits on their servers. A local-first app keeps your data on your device and in your own iCloud instead.
- Third-party accounts store a copy of your schedule.
- Local-first keeps data on your device and iCloud.
- Fewer copies means a smaller privacy surface.
How EventKit changes the model
Apple EventKit lets an app read and write the system Calendar and Reminders directly, with your permission, and nothing else. Kopit Cal uses EventKit, so it never creates a Kopit Cal account and never becomes a middleman holding your events. Multi-device sync happens through your existing iCloud, not through the app.
- EventKit reads and writes your system apps with permission.
- No Kopit Cal account is created.
- Sync rides on iCloud, not a third-party server.
What Kopit Cal does and does not collect
Kopit Cal is local-first: your events and tasks live in the system apps and your iCloud, and there is no analytics or tracking. The only network calls are for holiday feeds, which are fetched over HTTPS with nothing about you attached. That keeps the holiday features useful without turning them into a data trail.
- No account, no analytics, no tracking.
- Holiday feeds fetched over HTTPS with no personal data attached.
- Events and tasks never leave your Apple apps and iCloud.
