Hi @sujoy that’s a great question! Unique views are counted each time a person visits the form for the first time. It’s tracked by a cookie, so if they come back to the form again on the same browser/device, we’ll know that they’ve already visited the form. 

It’s important to note that if the respondent views the form for the first time on one device and then again on a different one, both of those times will be counted as unique since we can’t track across devices or different browsers (ex, if they first viewed on Chrome and then Safari). 

I hope this helps! Let me know if I can answer anything else.
