The DPA classifies personal data as "sensitive personal data" if it relates to:

• religious, philosophical, political or trade union-related views or activities;
• health, the intimate sphere of the person or racial origin;
• social assistance measures; or
• criminal or administrative proceedings and penalties.

Personal data within this definition will almost always relate to a natural person rather than a legal entity.

Financial data are not sensitive personal data under the DPA. Switzerland's banking secrecy law, however, protects the confidentiality of the existence of the banking relationship, the identity of the bank's customer and any other information related to the banking relationship.

Sensitive personal data are subject to enhanced legal protection under the DPA.
