    What is GDPR?

    The GDPR stands for the European Union's General Data Protection Regulation, which came into force in May 2018. It provides a comprehensive framework for the protection of personal data within the EU and sets out clear rules for the processing of this data.

    The main objectives of the GDPR are to protect privacy and strengthen the rights of individuals in relation to their personal data. The regulation gives people more control over their data and ensures that companies handle this information transparently and responsibly.

    The GDPR affects any company that processes the personal data of EU citizens, regardless of whether the company itself is based in the EU or not. Companies that violate the GDPR can be subject to substantial fines.

    What is nDSG?

    The nDSG stands for "new Data Protection Act" and refers to the revised Swiss Data Protection Act, which came into force on September 1, 2023. It is an update and amendment to the existing Data Protection Act (DPA) in Switzerland. The new DPA introduces important changes to data protection law and strengthens the protection of the privacy of individuals in Switzerland. It affects the way in which personal data is processed by organizations and website operators in Switzerland.

    The nDPA sets out how personal data should be processed on websites, particularly with regard to user consent and minimizing the use of data to what is necessary. It is important to note that the nDPA continues to require compliance with the European Union's (EU) General Data Protection Regulation (GDPR) for the data protection of EU citizens in Switzerland.
