CesiumEvents Privacy Policy

Last Updated: October 14, 2025

Introduction

Jucius Software ("we", "our", or "us") is committed to protecting your privacy. This Privacy Policy explains how CesiumEvents handles your data.

Data Collection

CesiumEvents accesses calendar event information from Apple Calendar on your Mac solely for the purpose of displaying events in the menu bar and showing timely notifications. The app reads:

  • Event titles
  • Event start and end times
  • Event locations (if available)
  • Calendar names and colors

Data Storage

Calendar event data:

  • Remains stored only in Apple Calendar on your local device
  • Is loaded into memory by CesiumEvents to display in the menu bar and schedule notifications
  • Is refreshed automatically every 10 minutes and when calendar changes are detected
  • Is never transmitted off your device or shared with third parties

User preferences are stored locally on your device using standard macOS storage (UserDefaults):

  • Selected calendars to monitor
  • Notification lead time preference (how many minutes before events to show notifications)
  • Launch at login preference

These preferences remain on your device and are never transmitted elsewhere.

Data Sharing and Transmission

CesiumEvents does not:

  • Transmit any calendar data to external servers
  • Share your calendar information with any third parties
  • Send any data over the internet
  • Collect analytics or usage data
  • Track your activities

Third-Party Access

CesiumEvents does not integrate with any third-party services or share data with any external entities. Your calendar data remains entirely on your device.

Permissions Required

CesiumEvents requires permission to:

  • Calendar Access: Read calendar events from Apple Calendar to display in the menu bar and show notifications

The app displays full-screen notification windows directly (not using macOS system notifications) and does not require separate notification permissions. You can revoke calendar access at any time through macOS System Settings, though this will prevent the app from functioning.

Data Security

CesiumEvents stores only user preferences locally on your device using standard macOS secure storage mechanisms. Calendar event data remains in memory only while the app is running and is never transmitted off your device. All data is protected by your Mac's operating system security and Apple Calendar's security measures.

Children's Privacy

CesiumEvents does not collect or transmit personal information. User preferences (calendar selections, notification timing) are stored locally on the device only. The app is safe for use by individuals of all ages, including children under 13.

Changes to This Policy

We may update this Privacy Policy from time to time. We will notify users of any material changes by updating the "Last Updated" date at the top of this policy.

Your Rights

Since we do not collect or transmit personal data, there is no personal data held by us for you to access or request deletion of. Your calendar data remains under your control within Apple Calendar. User preferences are stored locally on your device and can be reset by:

  • Changing settings within the app
  • Uninstalling the application (which removes all stored preferences)

Compliance

Our privacy practices are designed to comply with applicable privacy laws and regulations, including GDPR and CCPA, though the minimal data handling of our applications means most provisions do not apply.
