The GDPR and IAB Europe framework require that publishers provide a persistent link on their site that allows users to edit their consent preferences at any time. Below is an example of how that can be done with a simple link.
<a class="change-consent"
onclick="window.__tcfapi('displayConsentUi', 2, function() {} );">change consent</a>
By default, Quantcast Choice places a persistent button in the corner of the page if the user has valid consents. The buttons color and shape can be customized by using CSS overrides if desired.
There are 3 configuration options relevant to this button and its customization:
1. "Display Persistent Consent Link" (Edit a Theme)
Turns the persistent consent link button on or off.
2. "Persistent Consent Link Label" (Edit a Theme)
Customer label for the persistent consent link button.
3. "Persistent Consent Link Location" (Edit a Theme)
Which corner of the screen the "Privacy Settings" button is shown in.
