Data protection for private individuals in Switzerland
Statutory textStatus: 7 July 2025

1 A breach of personality rights is unlawful unless it is justified by the consent of the data subject, by an overriding private or public interest, or by the law.

2 The controller may have an overriding interest in the following cases in particular:

  • a.

    The controller processes personal data relating to a contracting party in direct connection with the conclusion or the performance of a contract.

  • b.

    The controller is or intends to be in commercial competition with another person and for this purpose processes personal data that are not disclosed to third parties; legal entities that belong to the same group of companies as the controller are not regarded as third parties for the purposes of this provision.

  • c.

    The controller processes personal data to verify the creditworthiness of the data subject, provided the following requirements are satisfied:

    • 1.

      The matter involves neither sensitive personal data nor high-risk profiling.

    • 2.

      The data are only disclosed to third parties if the third parties require the data for the conclusion or the performance of a contract with the data subject.

    • 3.

      The data are no more than ten years old.

    • 4.

      The data subject has attained the age of majority.

  • d.

    The controller processes the personal data professionally and exclusively for publication in the editorial section of a periodically published medium or the controller uses the data, if they are not published, as an aid to their own personal work.

  • e.

    The controller processes the personal data for purposes not related to specific persons, in particular for research, planning or statistics, provided the following requirements are satisfied:

    • 1.

      The controller anonymises the data as soon as the purpose of processing permits; if anonymity is impossible or if it requires disproportionate effort, the controller shall take appropriate measures to prevent the identification of the data subject.

    • 2.

      If the matter involves sensitive personal data, the controller shall disclose such data to third parties in such a manner that the data subject is not identifiable; if this is not possible, it must be guaranteed that the third parties only process the data for purposes unrelated to the data subject's person.

    • 3.

      The results are published in such a manner that data subjects are not identifiable.

  • f.

    The controller collects personal data relating to a public figure that relate to that person's public activities.

In brief

A breach of privacy is only unlawful if there is no justification – your consent, an overriding private or public interest, or the law. The article lists typical overriding interests, such as performing a contract or checking creditworthiness.

What does this mean for me?

There are limits to creditworthiness checks: the data may not be older than ten years and may only be disclosed for contracts with you.
