Privacy statement

Privacy statement
On May 25, 2018, the new European legislation GDPR came into effect. GDPR stands for General Data Protection Regulation, but in the Netherlands, the term AVG (Algemene Verordening Gegevensbescherming) is also used.

This European law was introduced to further protect the privacy of EU citizens. Privacy legislation is not new, of course. In the Netherlands, for example, we already had the Personal Data Protection Act. What is new, however, is that the same law will apply to all EU member states. Additionally, the GDPR is stricter in certain aspects than previous legislation.

At Thermen Maarssen, we stand for quality. Operating within legal frameworks is essential. Especially in the complex and sensitive area of our guests' privacy, we implement a transparent and correct policy. Thermen Maarssen has made transparent how personal data is handled and updated its privacy statement in preparation for this law.
