If you prefer the bar to be shown only once for a visitor, then you can use the cookie time setting to specify a time in hours that will prevent the bar from showing again to a particular visitor.
There is no limit on the number of hours. For example if you want to prevent the bar from showing for 30 days then you can specify 720 hours.
If you don't want to use the cookie function, then leave the number of hours as 0.
You can also control when the cookie timer starts:
Start cookie time when bar becomes visible (default) — the timer begins as soon as the bar is displayed to the visitor.
Start cookie time when bar is closed or button is clicked — the timer only starts after the visitor actively dismisses the bar or clicks the button. Use this option if you want the bar to keep reappearing until the visitor has explicitly interacted with it.
