Questions
Can this merge public calendar URLs?
This tool merges pasted or imported .ics calendar files locally. Public URL fetching is inactive while CORS, abuse, and privacy handling stay under review.
How are duplicate events handled?
Events with the same UID are treated as duplicates. Events without a UID use start time, end time, and summary as a fallback key.
Does this support recurring events?
Recurring event rules are preserved in the exported .ics file, but this tool does not expand recurring series into individual occurrences.
Does Utilumo upload my input?
No. This tool is designed for local browser processing and does not send your input to a server.
Do I need an account?
No. Utilumo tools are built to work without accounts or sign-in.
