Frequently asked questions


    

      What is an .ics file?
      
An .ics file is the standard calendar format (RFC 5545) used to
      move events between calendars. Import it into Google Calendar, Outlook, Apple
      Calendar, or Thunderbird and the event appears in your calendar.

    


    

      Does ICS Generator upload my event data?
      
No. The page itself uploads nothing and has no analytics beyond the
      cookie-free Cloudflare Web Analytics visit counter. Events are saved only
      in your browser's localStorage, so they survive a reload, and clearing
      the site's data removes them. The only way your data leaves your device
      is if you click an outbound link — for example the per-event Google
      Calendar link, which sends that event's details to Google to prefill its
      form — or download or share the .ics file yourself.

    


    

      Can I create recurring events or reminders?
      
Yes — daily, weekly, monthly, and yearly recurrence, with optional
      day-of-week patterns, occurrence counts, and end dates, plus reminders
      set per event — minutes, hours, or days before the start — and all-day,
      timed, and multi-day events with attendees. In one .ics file each event
      carries its own reminder.
