Legitimate Interest
Last updated: 14 March 2026
Publicit Global S.L.U (Passeig de Gràcia 19, Barcelona, Spain) relies on legitimate interest as a legal basis for certain limited data processing necessary for the proper operation of its Ad-Exchange and the protection of the platform and its users.
1. Scope of processing based on legitimate interest
We use limited, technically necessary data (e.g. IP addresses, session or transaction identifiers, strictly necessary device signals) for the purposes described below. This processing is based on our legitimate interest in operating a programmatic advertising service in a secure, transparent and efficient manner, balanced against your rights and privacy expectations.
2. Specific purposes
Security and integrity of the service
Limited data processing is necessary to ensure the security of our infrastructure, to detect and prevent unauthorised access, abuse and attacks that could affect the availability or integrity of the Ad-Exchange.
Fraud prevention
We use limited technical and usage data to identify and prevent fraudulent behaviour (e.g. invalid traffic, fake clicks or impressions, inventory or billing manipulation), thereby protecting advertisers, publishers and the platform itself.
Technical delivery of ads
For the Ad-Exchange to function correctly, it is necessary to process minimal technical data to enable delivery of the ad to the correct device, counting of impressions or events, and compliance with partner obligations (e.g. billing or attribution), always within the limits of legitimate interest and without broad profiling for personalisation where consent is not in place.
3. Safeguards
We limit the volume and retention period of data processed under legitimate interest to the minimum necessary. Where applicable, we respect IAB TCF v2.3 signals and consent preferences. You may object to certain processing based on legitimate interest through the options we offer on the platform or by contacting us.
4. Contact
To exercise your right to object or for any questions about processing based on legitimate interest, please contact us at info@publicit.com. For other rights (access, rectification, erasure, etc.) please see our Privacy Policy.
