Do I need a Cookie Notice when I use CAOS Pro?

In most situations, the answer to this question is: yes.

TL;DR: using CAOS Pro doesn’t automatically mean that you don’t have to use a cookie notice.

In some EU countries (i.e. Italy, The Netherlands and France), using analytics is considered a legitimate interest and is therefore exempt from prior consent, as long as no personal data is collected. In these countries, a cookie notice isn’t required when using Google Analytics 4 combined with CAOS Pro’s
increase GDPR compliance feature. 

However, in other EU countries (Austria, Belgium, Ireland, but also the UK) prior consent is
always required when the user’s browser is used for storing any information.

If you don’t have the means to investigate your specific situation, I’d say you should use a Cookie Notice to be safe. Otherwise, to get meaningful analytics, it might be worth to investigate if you don’t need a cookie notice.

In the GDPR era when using Google Analytics in most situations prior consent (the Cookie Notice) is required before you’re allowed to
track visitors from the European Union.
