New!  Functionality added March 10, 2018

All of our paid plans (Bootstrap, Startup, and Enterprise) allow a user to create a timer URL that will deliver the timer via HTTPS.

To change this option, use the new Paid Plan Options in the "View Embed Code" popup or on the Details page for the timer. The URL will update on the fly to use HTTPS. (You can of course change the URL to HTTPS manually, but you will receive an error if you do this on the Free plan)
