YOU call us

When you call us or one of our employees, we collect caller identification information (number display). If your telephone number is not suppressed or withheld, we will see the number on the display. This number is automatically stored in the call list along with the call date and time. We do not record the call itself. We use this information to call you back if necessary.

We do not record calls, but we make remarks and notes depending on the call so that we can discuss projects or an employee can contact you.

YOU send us an e-mail

If you write to us via the contact email address, we will answer your mail or forward it to the appropriate employee.

We also monitor all emails sent to us, including attachments, for viruses or malicious software. We process and store your data.

Disclosure of your personal data

Within our company, only those parties who need your data in order to fulfil our obligations will have access to it.

In addition, service providers or vicarious agents can receive data for the following purposes if they also comply with data protection regulations and we have concluded a corresponding contract with them.

If the data transfer according to Art. 6 para. 1b DSGVO is necessary for the execution of the contract with you, the personal data may be transferred to third parties involved. This includes e.g. business partners, subcontractors, suppliers in a joint project. 21-arch GmbH processes your data for the purpose of contract implementation, for the fulfilment of pre-contractual, contractual and post-contractual obligations, as well as for your direct contact for the implementation of the construction project. There are always corresponding agreements with the companies involved.

These can be companies in the following categories:

– public authorities (e.g. building law offices, tax authorities)

– companies involved in the planning and construction process. We expressly point out that data may be passed on at a very early stage for our type of work. This is a necessary process in order to be able to provide the service, partly also in order to be able to submit a plausible offer, in which we naturally observe all data protection aspects.

Companies or contract processors involved in the delivery process, to whom we send our
our business relationship (e.g. suppliers in the event of a dispute with a third party).

Third-party deliveries, IT administration, building management, payment card processing & payment transactions, marketing, personnel acquisition). Here we base our processing on the legal basis of Article 6 Para. 1 Letter c DS-GVO or Article 6 Para. 1 Letter f DS-GVO, since the processing is necessary to protect our legitimate interests.

Other data recipients may be bodies and companies for which you have given your consent for data transfer.

Data will only be transferred to countries outside the EU/EEA if locally deployed service providers or contract processors observe the requirements of the DSGVO in addition to written instructions (EU Privacy Shield, EU standard contract clauses).

Applicant data

We process your application documents in order to assess whether you are a potential candidate for our company. (Art. 6 I b.) DSGVO).

Since it may happen that we contain special categories of personal data, e.g. information about health, religious convictions or ethnic origin, we process your data on the basis of our legal obligations as an employer and the associated protection of your basic rights additionally to Art. 9 II b DSGVO. It may also happen that we assess your data in accordance with Art. 9 II h DSGVO in order to assess the employability of potential employees. We may be obliged to do so, as we may also be on construction sites where special occupational medicine and health care measures have to be observed.

The application process means that a few employees are involved and will have access to your documents.

We will not share the information you provide with any third party.

We use contact information solely to contact you and inform you of the progress of the application process.

Your personal data will be deleted at the end of the entire application process as soon as they are no longer required for the achievement of the purpose. If employment occurs after the application process, these documents are transferred to the personnel file.

In the event of rejection, your personal data will be deleted six months after receipt of the rejection. Longer storage is only possible if it is necessary to defend legal claims or if a short-term extension of this period is unavoidable for organisational reasons. An extension may also be considered if you allow us to do so on the basis of your consent in the event that we are allowed to approach you again at a later point in time. Otherwise, the same applies as stated under the deletion aspects. You can revoke any consent given to us at any time. You can object to the processing of your personal data at any time. Of course you have the possibility to withdraw and delete your application at any time.


If we advertise for other companies on our Internet pages, we will mark this advertising for you as advertising. You can clearly identify the location responsible for the use of the data.

– fair procedure
– proportionate to the purpose of the processing
– in a manner understandable to the data subject

If you come across any issues in this regard that you consider to be against these principles, please let us know. As we are always working on improvements, we take your suggestions on board and change the processes if necessary.

If you leave the 21-arch GmbH website via a link to an external website, we expressly point out that you are accessing another Internet provider. This means that the links marked in this way refer to content that is not stored on your own server. If this is not already clear from the text, we will, for example, provide the link to an external website with a note “external link”.

Obligation to store data

Unless there is a legitimate need for continued processing and storage, we will delete or anonymize your personal information.
