Privacy legislation (GDPR / AVG)

  • Personal data: data that directly or indirectly say something about you. For example, your name and address, but also your income.

  1. From whom does Diagonal Makelaardij process personal data?

We process personal data of people with whom we have, want to have, or have had a relationship, directly or indirectly. These are, for example, personal data of:

  • Customers and their representatives;

  • People who show an interest in our products and services,

  • People who are associated with a company or organization with which we have, want to get or have had a relationship.

  • Employees of Diagonal Makelaardij’s real estate agents.

Please note: if your company or organization passes on personal data of employees to us, you are obliged to inform your employees about this. You can give this privacy statement to them. Your employees can then see how we handle their personal data.

We may process personal data from third parties to protect your and our interests. We do this, for example, in the context of fraud prevention.


2. Who is responsible for the processing of my personal data?

All parts of Diagonal Makelaardij process personal data. Diagonal Makelaardij consists of Diagonal Makelaardij and its partners. Where we refer to Diagonal Makelaardij in this privacy statement, we mean Diagonal Makelaardij and its partners.

Do you want to know which part of Diagonal Makelaardij is responsible for the processing of your personal data? Please contact the division of Diagonal Makelaardij with which you do business.

3. For what purposes does Diagonal Makelaardij process personal data?

We process personal data for the following purposes:

a. To be able to enter into a relationship with you
If you want to become a customer with us or if you want to purchase a new product or service, we need personal data. For example, we must conduct an investigation to assess whether we can accept you as a tenant, or whether we can sell your home. For this, we can also use information from you that we receive from others. For example, credit check agencies such as EDR and Experian. We can also use the data we receive from you and have recorded about you to make analyzes to assess whether you are eligible for a particular product. We may also make a copy of your proof of identity when entering into a relationship.

b. To maintain the relationship with you and to carry out assignments
If you are a customer of ours, we want to serve you well. For this, we process personal data. We use your name and address details, for example, to maintain contact with you.

c. To protect your and our interests We may process personal data to protect your and our interests and those of our sector. For example, to prevent or investigate fraud. For this purpose, we may consult the incident registers and warning systems of the sector and record personal data in them. We can also consult public sources for this purpose such as public registers, newspapers, and the internet. In order to combat cybercrime such as botnets, we may pass on your data to third parties engaged in the fight against cybercrime. We only do this if we have made agreements with these parties about the careful use of your data.

d. For the development and improvement of our products and services
In order to continue to serve you well, we are constantly working on the development and improvement of our products and services. In some cases, we process personal data for this. For example, if you ask a question about a product.

e. For promotional and marketing purposes
We may process your personal data for promotional or marketing purposes. For example, to inform you about a new product that may be of interest to you or to better respond to your wishes. Do you not want to be contacted for commercial purposes? Then you can indicate this at the section of Diagonal Makelaardij that you do business with. We may link your use of our website to the information we know about you in order to improve our services and to show advertisements relevant to you. We can also use the data we have recorded about you to perform analyzes. With the help of these analyzes, we can improve the service to you. We can also use the analysis to provide insight to our customers for benchmarking purposes.

f. To enter into and execute agreements with suppliers and business customers.
If you have contact with Diagonal Makelaardij’s agents for your work, we can process your personal data. For example, to determine whether you may represent your company. Or to give you access to our offices.

g. To fulfill legal obligations
We must collect information about you on the basis of certain laws and regulations. Pursuant to the Money Laundering and Terrorist Financing (Prevention) Act (WWFT), for example, we must conduct a (further) investigation if there could be an unusual transaction. We must also determine, on the basis of the WWFT, who is the ultimate owner of a company with which we have a relationship. Legislation and regulations may also oblige us to pass on (analyzed) data about you to a government agency, a tax authority, or to a supervisory authority within or outside the Netherlands. For example, to the Netherlands Authority for the Financial Markets. Because we have to comply with legal obligations and treaties, we sometimes have to provide information about you to the Dutch tax authority.

h. For our business operations
As a service provider, we find it important and it is necessary that we have a good overview of our customer relationships. This also includes knowing whether you are collaborating with other parties that may pose a risk. We process personal data in order to obtain this overview and then take measures.

i. For archival purposes
We do not collect more personal data than is necessary for the aforementioned purposes. If we do not keep the data for those purposes, we can still keep the data for archival purposes. This means that the data is only used in legal proceedings or for historical, statistical, or scientific purposes.


4. Does Diagonal Makelaardij also process special personal data?
Special personal data are sensitive data. For example, about health, criminal record, ethnic data, or data concerning race. Diagonal Makelaardij does not process special personal data unless we have to do so on the basis of the law, with your permission or if you ask us to. Do you ask us to record special personal data about you or do you disclose this data yourself? Then we only process this data if this is necessary for our services.


5. How does Diagonal Makelaardij handle my personal data?
Your personal data will be carefully stored and no longer than is necessary for the purpose for which they were processed. Within Diagonal Makelaardij, your personal data can only be used by employees who need access to this in view of their position. Our employees have a duty of confidentiality. Do we want to use data for a purpose other than that for which it was originally processed? Then we can only do that when there is a close relationship between the two goals. Your personal data can also be exchanged between the parts of Diagonal Makelaardij. But only when this is compatible with the purpose for which the data was collected. Data with which your identity has been established can, for example, also be used by another part of Diagonal Makelaardij with which you want to do business. If we act as an intermediary, we must exchange personal data. Sometimes we engage third parties who process personal data on our behalf. For example, a printing company that provides a customer mailing for us and prints name and address details on envelopes. We can only engage third parties if this suits the purpose for which we have processed your personal data. For example for promotional and marketing purposes. In addition, this third party can only receive our assignment if it has demonstrably taken appropriate security measures and guarantees confidentiality.

Your personal data may be subject to investigation both during and after processing by competent national authorities of the countries where such data is located due to the processing process.

Your personal data can also be provided to third parties if we have a legal obligation to do so. For example, to the tax authorities or to a supervisor. Your personal data will not be sold or rented.

When processing personal data in the Netherlands, Diagonal Makelaardij is bound, among other things, to:

  • General data protection regulation (GDPR)

  • The Telecommunications Act

Where necessary, the processing of personal data by the various parts of Diagonal Makelaardij has been registered with the Dutch Data Protection Authority.


7. Can I see which of my personal data Diagonal Makelaardij processes?
