How do I reset my private URL?

If your private URL is exposed to unauthorized users, you can prevent their access by resetting the URL. To reset your private URL, go to Settings > Calendar > My calendar > Sharing and permissions > Private URL . Click the reset option next to the private URL to reset both your iCal URL and HTML URL of your private calendar. Once reset, the exposed URL will not be usable.

Refer here for more detailed information on sharing private calendars.

Note : Reset the iCal URL immediately if exposed publicly.
