Article 7(3) of the GDPR prescribes that the controller must ensure that consent can be withdrawn bythe data subject as easy as giving consent and at any given time. The GDPR does not say that givingand withdrawing consent must always be done through the same action.

consent is obtained through use of a service-specific user interface (for example, via a website, an app,a log-on account, the interface of an IoT device or by e-mail), there is no doubt a data subject must beable to withdraw consent via the same electronic interface, as switching to another interface for thesole reason of withdrawing consentwould require undue effort.

The controller informs customers that they havethe possibility to withdraw consent. To do this, they could contact a call centre on business daysbetween 8am and 5pm, free of charge. The controller in this example doesnotcomply with article 7(3)of the GDPR. Withdrawing consent in this case requires a telephone call during business hours, this ismore burdensome than the one mouse-click needed for giving consent through the online ticketvendor, which is open 24/7.

To be fully compliant with GDPR, you would also need to enable Show Reject All Button setting.
