CNIL’s Fnac Darty fine puts recommender telemetry under cookie rules
The French sanction is a practical warning for apps that use browsing history to personalize products and train recommendation algorithms.
- Treat recommendation telemetry as a consent issue when it uses browsing history for personalization or algorithm training.
- Separate analytics, recommendations, and model training in consent design instead of bundling them under one vague purpose.
- Verify that refusal stops the relevant tracker before behavioral data leaves the app.
