The challenge

- Little centralized visibility on when and how the users gave their consent.
The solution
To ensure global consistency and transparency, proactive, Carrefour implemented:
- OneTrust Consent & Preferences in more than 160 sites and 30 mobile apps, including modules, designed for web and mobile devices.
- A banner uniform consent present in all points of the digital input, adapted by country, even in markets with regulations softer as Argentina and Taiwan.
- A platform centralized to consolidate consents and preferences, to improve the analysis and compliance cross-border.
Top results

- Uniform experience and confidence: users experienced the same interface and transparency in all countries, reinforcing the perception of seriousness.
- Increases in the rates of opt‑in: the clarity and ease of the banner significantly improved the willingness of users to authorize their data.
