YOU call us

When you call us or one of our employees, we collect caller identification information (caller identification 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 together 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 do make remarks and notes depending on the call so that we can discuss projects or a member of our staff 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 e-mails sent to us, including file attachments, for viruses or malicious software. In doing so we process and store your data.

Disclosure of your personal data

Within our company, only those entities that need to have access to your data in order to fulfil our obligations will have access to your data.

Additional service providers or vicarious agents may 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 transfer of data is necessary for the execution of the contract with you according to Art. 6 para. 1b DSGVO, the personal data may be passed on to third parties involved. This includes, for example, business partners, subcontractors, suppliers in a joint project. 21-arch GmbH processes your data for the purpose of implementing the contract, for the fulfillment of pre-contractual, contractual and post-contractual obligations, as well as for your direct contact for the implementation of the construction project. Appropriate agreements always exist with the companies involved.

These can be companies of 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 for our type of work, data may be passed on at a very early stage. This is a necessary process in order to be able to provide the service, sometimes also to be able to submit a plausible offer, in which we naturally observe all data protection aspects.

companies involved in the delivery process or contract processors, to whom we can deliver
execution of our business relationship (e.g. suppliers at

third-party deliveries, IT administration, facility management, payment card processing & payment transactions, marketing, personnel acquisition). Here we base our processing on the legal basis of Article 6 Paragraph 1 Letter c DS-GVO or Article 6 Paragraph 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 to the transfer of data.

Data will only be transferred to countries outside the EU/EEA if local service providers or contract processors comply with the provisions of the DSGVO in addition to written instructions (EU Privacy Shield, EU standard contractual clauses)

Applicant data

We process your application documents to be able to assess whether you are a possible candidate for our company. (Art. 6 I b.) DSGVO).

As it is possible that the application documents may contain special categories of personal data, e.g. information on health, religious conviction 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, also in accordance with Art. 9 II b DSGVO. Furthermore, it may also occur that we use your data in accordance with Art. 9 II h DSGVO to assess the employability of potential employees. We may be obliged to do this, as we may also be working on construction sites where special occupational health and safety measures must be observed.

The application process means that a small number of employees will be involved and will also have access to your documents.

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

We will only use contact data to contact you and inform you about the progress of the application process.

Your personal data will be deleted at the end of the entire application procedure as soon as they are no longer required for the purpose for which they were collected. If an employment is created after the application process, these documents are transferred to the personnel file.

In the event of a rejection, your personal data is deleted six months after receipt of the rejection. Longer storage is only considered 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 contact you again at a later date. Otherwise, what is stated under the deletion aspects applies accordingly. You may revoke any consent granted 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 your application at any time and have it deleted.
