CalendarDeduplicator for Mac

CalendarDeduplicator helps you find, review, and safely remove duplicate events from your Mac calendars. Analysis happens locally on your Mac, so calendar data is not uploaded to the developer.

Review exact and uncertain matches, compare event details, use Simple or Expert mode, and choose exactly which copies to remove. Before every deletion, the app creates a local backup, and immediate Undo lets you restore the events that were actually removed.

Features:

• On-device duplicate analysis.
• Confidence scores and detailed event comparison.
• Simple and Expert review modes.
• Flexible time and overlap rules.
• Automatic local backups and restore.
• Undo after deletion.
• Responsive progressive analysis for large calendars.
