Frequently Asked Questions

Which apps import the .ics?

Google Calendar, Apple Calendar, and Outlook all import .ics natively — one file covers every guest regardless of their app.

What fields should I fill?

Summary, start/end with timezone, location, and description with the meeting link. Timezone-correct entries prevent the classic 3am-invite bug.

Recurring events supported?

Single events export cleanly; complex recurrence rules vary by importer — send one file per occurrence for critical meetings.

Is event data uploaded?

No — file building runs locally in your browser. Only the .ics download touches disk.

What does 10:00 on 2026-07-20 become in the file?

DTSTART:20260720T100000 — floating local time with no zone suffix. Only DTSTAMP is UTC (...Z, stamped at generation); VERSION:2.0 and PRODID:-//ToolHub//EN are fixed, and empty description/location lines are omitted.
