Actually, the SP Cookie Consent doesn't save any cookie details at back end.
The Cookie Consent plugin lets you display a cookie (or other legal) notice on your Joomla website and inform the visitors that your site uses cookies. Inside Textarea field you can use HTML tags. This plugin presents your cookie and privacy notice when someone visits your site for the first time. You can easily set a text and links (via HTML tags) to documents as the notice along with a custom color for the notification area. Then you can choose a position used in the template.
So, it's just simple text notice to inform the visitors that your site uses cookies.
Best Regards
