Switzerland: Federal Data Protection and Information Commissioner adopted guide on data processing through cookies

On 22 January 2025, the Federal Data Protection and Information Commissioner adopted the guide on data processing through cookies. The guide applies to website operators using cookies for non-essential purposes including personalisation and advertising. The guide highlights the principle of transparency, requiring operators to inform users about data collection and processing. It also requires operators to obtain explicit, voluntary, and revocable consent, particularly for high-risk data activities such as profiling. Operators must ensure that consent is clear and user-friendly, allowing users to opt in or out of specific cookie types, without any undue pressure.
