Data protection

Data protection

Data protection has always been very important to us.

As notaries, we attach particular importance to the security of your personal data.

We only process your personal data to the extent that this is necessary for the establishment of contact desired by you or provision of the notarial services mandated by you or is required by law. In addition, notaries are required to maintain privacy and confidentiality pursuant to Section 18 of the German Federal Regulation on Notaries (BNotO). All our employees are also obliged to do so. Violation of the notarial confidentiality obligation is usually punishable. We have concluded corresponding confidentiality agreements with external service providers or processors for your protection in the context of the legal obligations.

Our legitimate interest follows from the data collection purposes listed above. In no case do we use the collected data for the purpose of drawing conclusions about your person. These data are also not combined with other data and user profiles are not created.
