IAB purposes are automatically associated with the vendors you select. Vendors may choose to use legitimate interest as a legal basis for their purposes. It is up to you to remove it if you wish. **What is legitimate interest?**  Legitimate interest is a specific legal basis, different from consent. It allows the automated processing of personal data, subject to a certain number of conditions: this processing must be legitimate, necessary, and not prejudice the rights and interests of individuals. This is a legal basis that is rarely used in France, except in special cases. To know when legitimate interest can apply under GDPR, please consult your legal department/ DPO. If some of your vendors' purposes are automatically based on legitimate interest (as below) and you want to change this, you can follow the steps described below. ![Screenshot 2023-03-08 at 10.01.37](https://support.didomi.io/hs-fs/hubfs/Screenshot%202023-03-08%20at%2010.01.37.png?width=406&height=372&name=Screenshot%202023-03-08%20at%2010.01.37.png) The methods at your disposal will depend on the type of vendor involved Please keep in mind that : ⚠️ Removing legitimate interest can impact your monetization. 1\) For IAB and ATP (Google) vendors  - Create a publisher restriction to change the legal basis of a purpose The "IAB TCF PUBLISHERS Restrictions" section is available in the Vendors & Purposes tab of your notice above the list of purposes. 1.
