There are 2 main modes of CookieScript depending on how strict you want it to be and it's called Consent mode:

Implied: All cookies are set at the visitor’s computer as usual and the visitor is just informed about cookies. Cookies are deleted only if the user declines cookies. We call it “the soft way”

Explicit: This option is used by default because that's a requirement for GDPR. If this option is used, no cookies will be stored on the visitor’s computer until the visitor agrees with the Cookie Policy. We call it “the hard way”.

Things to note when using explicit mode:

1. Removing cookies can influence the workflow of your website. For example, the visitor will not be able to log in until he agrees with your Cookie Policy. If you have a webshop, it is not recommended to use explicit mode since visitors will not be able to make any purchases before they agree with the cookie policy.
2. If you are using some analytics software (like Google Analytics), explicit Cookie Consent mode might mess up your analytics data since each page view (even from the same visitor) will be tracked as a new and unique visitor.
3. In case you have a simple website without any analytics software installed, you should not have any problems using explicit Cookie Consent mode.
