Frequently Asked Questions

Why is the app named "CesiumEvents"?

Cesium is the element used in atomic clocks, the most accurate timekeeping devices in the world. The name reflects our commitment to helping you stay precisely synchronized with your schedule.

Is CesiumEvents a simple application?

Yes, by design. CesiumEvents focuses on doing one thing exceptionally well: ensuring you never miss a calendar event. It displays full-screen notifications when your events are approaching, preventing you from overlooking small corner notifications when you're in a flow state or focused on other tasks. The intentional simplicity means you never accidentally miss an important meeting.

Does CesiumEvents work with Outlook, Google Calendar, and other calendar services?

Yes, through Apple Calendar's native integrations. CesiumEvents works with Apple Calendar, which supports a wide range of calendar services including Outlook, Google Calendar, Exchange, iCloud, and others. Simply add your calendar accounts to Apple Calendar, and CesiumEvents will notify you of all your events across all connected calendars.

How does CesiumEvents protect my privacy?

Your calendar data remains completely private and secure. CesiumEvents only reads calendar data from Apple Calendar for the sole purpose of displaying notifications on your screen. The app never saves your calendar information to disk and never transmits any data over the network. All processing happens locally on your Mac, ensuring your schedule stays yours alone.

Does CesiumEvents require an internet connection?

No, CesiumEvents works entirely offline. Since the app only reads from Apple Calendar locally on your Mac, no internet connection is required for notifications to function properly.

What macOS versions does CesiumEvents support?

CesiumEvents requires macOS 14 (Sonoma) or later. The app is designed to work seamlessly with modern macOS systems and takes advantage of the latest Apple Calendar integrations.

Can I choose which calendars to monitor?

CesiumEvents monitors all calendars that are enabled in Apple Calendar. To control which calendars generate notifications, simply enable or disable specific calendars within Apple Calendar's preferences, and CesiumEvents will respect those settings.

What permissions does CesiumEvents need?

CesiumEvents requires Full Calendar access to read your events. Apple does not provide a read-only calendar permission option, so the app must request full access. However, rest assured that CesiumEvents never writes anything to your calendar—it only reads event data to display notifications. No other system permissions are needed.

How can I try out CesiumEvents?

CesiumEvents is free to use for 7 days. After the trial period ends, the product won't display any event notifications unless you purchase the full product.

Is there a subscription to get the full product?

No. When you purchase CesiumEvents, it's a one-time fee and you'll be able to use the product moving forward. There are no recurring charges or subscription fees.
