Now let's start with Part 1:

What privacy laws govern data protection in Switzerland?

In this first part of our series, we explore what privacy laws govern data protection in Switzerland, to whom they apply and who is responsible for ensuring compliance.

Main privacy legislation in Switzerland

The cornerstone of Swiss data protection law is the Federal Act on Data Protection (FADP), which was fully revised and came into force on 1 September 2023. The FADP governs the processing of personal data by private-sector organisations and federal bodies. The FADP is complemented by the Ordinance on Data Protection and the Ordinance on Data Protection Certification. The authority overseeing compliance with the FADP is the Federal Data Protection and Information Commissioner (FDPIC).

The processing of personal data by cantonal and communal authorities is governed by cantonal data protection laws. The application of these laws is overseen by the cantonal data protection authorities.

Does the FADP apply to foreign companies?

The FADP has an extraterritorial scope, meaning that it applies to activities that have an effect in Switzerland, even if they are initiated abroad. Organisations established outside Switzerland may therefore also be subject to the FADP if they process the personal data of Swiss residents.

Private controllers established outside Switzerland that process the personal data of persons in Switzerland must appoint a representative in Switzerland if the processing:

  • is related to the offering of goods or services to or the monitoring of the behaviour of persons in Switzerland,
  • is on a large scale,
  • is carried out regularly, and
  • poses a high risk to the personality of the data subjects.

The representative serves as a contact point for data subjects and the FDPIC, and its name and address must be published by the controller.

Other laws that impact data protection

The Swiss Federal Act on Information Security applies to federal and cantonal authorities and to private-sector operators of critical infrastructure, such as energy & drink water supply, waste disposal, finance, healthcare, information & communication, food & drink, transport, traffic, safety and security.

Certain general laws also have an impact on data protection, such as the Federal Act on Unfair Competition, which contains regulations on direct marketing, and the Telecommunications Act, which regulates the use of cookies.

Furthermore, there are several sector-specific laws that contain dispositions on data protection, for example in the medical sector (Federal Act on Research Involving Human Beings, Federal Act on the Electronic Patient Record, etc.), or in the financial sector (Federal Banking Act, Federal Act on Financial Institutions, etc.).

In part 2 of our series, we will explore the definition of personal data under the FADP.
