I think lucablue is asking about recording proof that the user ticked the box to accept, which we are required to keep as proof of consent. We achieve this through the use of CB Profile Update Logger - not only does it store it in the database, but it shows it on the User profile and it sends an email to us
(example: L123min has updated their profile. Changed: 2. Pending Changes: 0.
cb_dataprivacy: "0" to "1"
cb_consent: "0" to "1")
This is perfect for record of proof.
