Yeah, no. This about the ePrivacy directive, if you don't have proper consent, you can't read/write tracers regardless of wether this is personnal data or not, except for tracers needed to establish the communication or demanded by the user (carts, login, etc).

EDIT: Thought about it, and if you only record the button click and does not identify the user, it works, and I am wrong! In general ePrivacy is very restrictive, only about access to terminal and not about personnal data ( and btw PII is not a GDPR thing, we say personnal data), but here it's ok! So yeah, no to me!

There’s no tracer. Just a counter of how many said yes vs how many said no. There’s no personally identifiable information there

the downside of this method is that it is impossible to discard duplicated negative answers.

Functional cookies (e.g has displayed banner to this user) are fine, you don't need consent

GDPR defines what is PII and then regulates when companies may use PII. A page visit counter collects anonymous data. Anonymous data is not PII. You cannot tell I was their 345th visitor.

>> Yeah, no.

Exactly.
