Frequently Asked Questions
What is Legitimate Interest (LI) in GDPR?▾
Legitimate Interest (Art. 6(1)(f) GDPR) is a legal basis for processing personal data without explicit consent when the controller has a genuine business need, provided it does not override the individual's rights and freedoms. A Legitimate Interest Assessment (LIA) must be documented.
Why is LI abuse a problem?▾
Some advertising vendors claim "legitimate interest" as their legal basis for tracking and profiling users, bypassing consent requirements. EU Data Protection Authorities have repeatedly ruled that personalised advertising cannot rely on LI because it overrides users' fundamental rights to privacy.
What is the TCF framework?▾
The Transparency & Consent Framework (TCF) by IAB Europe allows publishers and vendors to manage consent and LI claims in a standardized way. In 2024, IAB Europe was fined and required to remove LI as a legal basis for personalised advertising purposes (purposes 3-6) in the TCF.
What fines have been issued for LI abuse?▾
Major fines include: Meta EUR 390M (2023) for using LI/contract for behavioral ads, Criteo EUR 40M (2023) for LI-based advertising without consent, Amazon EUR 746M (2021) for advertising without adequate consent. These fines signal a clear regulatory trend against LI for advertising.
How does this tool detect LI abuse?▾
We scan your page for 10 advertising vendors with known LI enforcement history, detect your CMP/TCF framework, and analyze your privacy policy for phrases claiming legitimate interest for advertising purposes. The combination reveals potential LI abuse risks.
What should I do if LI abuse is detected?▾
Switch all advertising and profiling trackers to a consent-based legal basis. Ensure your CMP properly gates these trackers behind explicit opt-in consent. Review your privacy policy to remove any LI claims for advertising. Consider privacy-first alternatives like Zenovay Analytics.
