Chrome's Quiet Installation of Gemini Nano Sparks EU Privacy Controversy

Google has integrated Gemini Nano directly into the desktop version of Chrome, allowing generative AI features to run on-device and reducing the need to upload data to the cloud. However, the EU's ePrivacy Directive generally requires companies to obtain consent before accessing or storing information on users' devices. Deploying the model without clear notice has therefore raised compliance concerns.

Privacy researchers said Chrome appeared to have quietly downloaded about 4GB of Gemini Nano since late April 2026 without users' explicit permission. Google said the model would be uninstalled if the system determined that a computer lacked sufficient resources. The EU has not announced a formal case or any fine, and regulators have yet to decide whether to open an investigation.
