Website owners are legally obliged to let visitors revoke (take back) a previously given consent and must also be able to document any consent choice made by any visitor. Both of these are possible with Cookie Consent.
Consent logging
Every time someone accepts cookies on a website, proof of that consent must be stored so that it can be retrieved in the unlikely event that the visitor requests documentation that he or she did in fact consent. The visitor has the right to request this according to certain legal frameworks such as the GDPR's right to transparency.
Consent information is stored on Cookiebot's servers and we'll be able to retrieve it on request. In order to match a consent with a specific visitor, Cookiebot adds a unique identifier called consent ID to each consent provided.
If a visitor requests proof that they consented or withdrew a consent to cookies, you can ask them to locate this ID and send it to you. You can then pass it on to us in a Service Desk ticket so we can look it up in the consent database and provide proof of consent.
Where do visitors find the consent ID?
The visitor's most recent consent choice and their consent ID can be located in the cookie declaration.
Consent ID traceability
The consent ID is stored in a cookie in the visitor's local storage. Be aware that if the visitor clears cookies on their browser, the consent ID will also be cleared and we will no longer be able to trace that visitor's unique consent.
Consent revocation
Enabling the consent widget
The easiest way for visitors to change their consent, is through the consent widget. The consent widget is deactivated by default, but you can activate it under Website settings > Cookie notification.
Once activated, the website visitors will see a cookie widget icon on the website. They can open it by clicking on it, then change their preferences.
Changing consent on the cookie declaration
Visitors can revoke their consent or change consent preferences at any time on the cookie declaration.
Manually adding a "withdraw/renew consent" button
If you do not wish to make use of the cookie declaration, then you must provide alternative ways for the user to easily withdraw their consent.
This can be achieved by inserting the JavaScript functions "Cookiebot.renew()" or “Cookiebot.withdraw()” which will renew or withdraw a consent by showing the cookie consent banner to the visitior:
<a href="javascript: Cookiebot.renew()">Change your consent</a>
<a href="javascript: Cookiebot.withdraw()">Revoke your consent</a>
For example, if you wish to insert a "renew consent" link in the website footer, you can add the following snippet into an HTML module:
<a style="color:white; text-align:center;"href="javascript: Cookiebot.renew()">Change your cookie preferences</a>
This creates a link which, when clicked, displays the cookie banner to the visitor:
