Didomi Consent and Preference Management Platform

Didomi SAS is a privacy technology company registered in Paris, France, led by founder and CEO Romain Gauthier. It helps brands, publishers and apps collect valid consent and preferences across web, mobile and connected TV under GDPR, US state laws, Quebec Law 25 and other regimes while keeping marketing data usable. The company says more than 2,000 clients use its products.

The platform includes a multi-regulation consent management platform with IAB TCF, GPP and Google, Amazon and Microsoft consent signals, a preference management platform for communication choices, advanced compliance monitoring that scans trackers and scripts, a privacy request module for data subject requests, and Addingwell server-side tagging. Consent data can flow to tools such as Snowflake. Customers include Europcar and Chantelle.

• Multi-regulation CMP: Consent banners for web, mobile apps and connected TV.
• Consent signals: Supports IAB TCF, GPP, GPC, Google Consent Mode v2, Amazon and Microsoft UET.
• Preference management: Self-service center for communication and data choices.
• Compliance monitoring: Scans trackers and scripts to detect non-compliant behaviour.
• Privacy requests: Workflow for data subject access and deletion requests.
• Addingwell server-side tagging: Moves tracking server-side to improve data quality.

A Vietnamese online news publisher can manage consent for programmatic advertising under IAB TCF. A retail chain can unify customer marketing preferences from its app, website and loyalty program. A streaming or connected TV service can collect consent on smart TV apps.

Brands can run one consent setup across websites, apps and CTV for many regulations. Customers report higher consent rates, such as +12% at Europcar, and Chantelle recovered 12% of traffic data. Server-side tagging and consent signals reduce data loss in Google, Amazon and Microsoft ads. Compliance monitoring flags trackers firing without consent.

Consent is becoming a measurable growth lever as browsers cut third-party cookies and ad platforms require consent signals. In Vietnam, the 2026 Personal Data Protection Law and Decree 356 treat behavioural tracking data more strictly, so retailers, media and apps need consent and preference tools that also protect marketing performance.
