Privacy policy
Status: April 2025
1. Introduction
With the following information, we would like to give you as a "data subject" an overview of the processing of your personal data by us and your rights under data protection laws. It is generally possible to use our website without entering personal data. However, if you wish to make use of special services of our company via our website, it may be necessary to process personal data. If the processing of personal data is necessary and there is no legal basis for such processing, we generally obtain your consent. The processing of personal data, such as your name, address or e-mail address, is always carried out in accordance with the General Data Protection Regulation (GDPR) and in accordance with the country-specific data protection regulations applicable to "VIER GmbH", in particular the Federal Data Protection Act (BDSG). By means of this data protection declaration, we would like to inform you about the scope and purpose of the personal data we collect, use and process. As the controller, we have implemented numerous technical and organizational measures to ensure that the personal data processed via this website is protected as completely as possible. Nevertheless, internet-based data transmissions can generally have security gaps, so that absolute protection cannot be guaranteed. For this reason, you are free to transmit personal data to us by alternative means, for example by telephone or post.
2. Responsible person
The controller within the meaning of the GDPR is
VIER GmbH
Hamburger Allee 23
30161 Hannover Germany
Representative of the controller: Rainer Holler

E-mail: datenschutz@vier.ai
You can contact our data protection officer directly at any time with any questions or suggestions regarding data protection.
4. Definitions
The data protection declaration is based on the terms used by the European legislator for the adoption of the General Data Protection Regulation (GDPR). Our privacy policy should be easy to read and understand for the public as well as for our customers and business partners. To ensure this, we would like to explain the terminology used in advance. We use the following terms, among others, in this privacy policy Art. 4 of the General Data Protection Regulation (GDPR):
1. Personal data
Personal data means any information relating to an identified or identifiable natural person. An identifiable natural person is one who can be identified, directly or indirectly, in particular by reference to an identifier such as a name, an identification number, location data, an online identifier or to one or more factors specific to the physical, physiological, genetic, mental, economic, cultural or social identity of that natural person.
2. Data subject
Data subject is any identified or identifiable natural person whose personal data is processed by the controller (our company).
3. Processing
Processing is any operation or set of operations which is performed on personal data or on sets of personal data, whether or not by automated means, such as collection, recording, organization, structuring, storage, adaptation or alteration, retrieval, consultation, use, disclosure by transmission, dissemination or otherwise making available, alignment or combination, restriction, erasure or destruction.
4. Restriction of processing
Restriction of processing is the marking of stored personal data with the aim of limiting its future processing.
5. Profiling
Profiling means any form of automated processing of personal data consisting of the use of personal data to evaluate certain personal aspects relating to a natural person, in particular to analyze or predict aspects concerning that natural person's performance at work, economic situation, health, personal preferences, interests, reliability, behavior, location or movements.
6. Pseudonymization
Pseudonymization is the processing of personal data in such a manner that the personal data can no longer be attributed to a specific data subject without the use of additional information, provided that such additional information is kept separately and is subject to technical and organizational measures to ensure that the personal data are not attributed to an identified or identifiable natural person.
7. Processor
Processor is a natural or legal person, public authority, agency or other body which processes personal data on behalf of the controller.
8. Recipient
Recipient is a natural or legal person, public authority, agency or another body, to which the personal data are disclosed, whether a third party or not. However, public authorities which may receive personal data in the framework of a particular inquiry in accordance with Union or Member State law shall not be regarded as recipients.
9. Third party
A third party is a natural or legal person, public authority, agency or body other than the data subject, controller, processor and persons who, under the direct authority of the controller or processor, are authorized to process personal data.
10. Consent
Consent is any freely given, specific, informed and unambiguous indication of the data subject's wishes by which he or she, by a statement or by a clear affirmative action, signifies agreement to the processing of personal data relating to him or her.
5. Legal basis of the processing
Art. 6 para. 1 lit. a GDPR (in conjunction with § 25 para. 1 TDDDG) serves our company as the legal basis for processing operations for which we obtain consent for a specific processing purpose.
If the processing of personal data is necessary for the performance of a contract to which you are a party, as is the case, for example, with processing operations that are necessary for the delivery of goods or the provision of another service or consideration, the processing is based on Art. 6 para. 1 lit. b GDPR. The same applies to such processing operations that are necessary to carry out pre-contractual measures, for example in cases of inquiries about our products or services.
If our company is subject to a legal obligation which requires the processing of personal data, such as for the fulfillment of tax obligations, the processing is based on Art. 6 para. 1 lit. c GDPR.
In rare cases, the processing of personal data may be necessary to protect the vital interests of the data subject or another natural person. This would be the case, for example, if a visitor were injured in our company and their name, age, health insurance details or other vital information would have to be passed on to a doctor, hospital or other third party. The processing would then be based on Art. 6 para. 1 lit. d GDPR.
Finally, processing operations could be based on Art. 6 para. 1 lit. f GDPR. This legal basis is used for processing operations which are not covered by any of the abovementioned legal grounds, if processing is necessary for the purposes of the legitimate interests pursued by our company or by a third party, except where such interests are overridden by the interests or fundamental rights and freedoms of the data subject which require protection of personal data. We are permitted to carry out such processing operations in particular because they have been specifically mentioned by the European legislator. In this respect, it took the view that a legitimate interest could be assumed if you are a customer of our company (Recital 47 Sentence 2 GDPR).
6 Data collection when visiting the website
If you only use our website for informational purposes, i.e. if you do not register or otherwise provide us with information, we only collect the data that your browser transmits to our server (in so-called "server log files"). Our website collects a range of general data and information each time you or an automated system accesses a page. This general data and information is stored in the server log files. The following can be recorded
Browser types and versions used,
the operating system used by the accessing system
the website from which an accessing system reaches our website (so-called referrer)
the sub-websites which are accessed via an accessing system on our website
the date and time of access to the website
a shortened Internet Protocol address (anonymized IP address),
the Internet service provider of the accessing system.
When using this general data and information, we do not draw any conclusions about your person. Rather, this information is required in order to
deliver the content of our website correctly
optimize the content of our website and the advertising for it
ensure the long-term functionality of our IT systems and the technology of our website, and
to provide law enforcement authorities with the information necessary for prosecution in the event of a cyber attack.
This collected data and information is therefore evaluated by us both statistically and with the aim of increasing data protection and data security in our company in order to ultimately ensure an optimal level of protection for the personal data processed by us. The anonymous data of the server log files are stored separately from all personal data provided by a data subject.
The data stored in the server log files is stored for a maximum of 14 days and then deleted. Any further storage will only take place in anonymized form, so that it is no longer possible to assign the data to a specific person. The legal basis for data processing is Art. 6 para. 1 sentence 1 lit. f GDPR. Our legitimate interest follows from the data collection purposes listed above.
Our website is hosted by Vercel Inc, 440 N Barranca Ave #4133, Covina, CA 91723, USA. When our website is accessed, Vercel processes various personal data, in particular the visitor's IP address, date and time of access, browser type and operating system, referrer URL.
The processing is carried out on the basis of Art. 6 para. 1 lit. f GDPR due to our legitimate interest in the secure and efficient provision of our website.
We have concluded an order processing contract with Vercel in accordance with Art. 28 GDPR. A transfer of personal data to the USA cannot be ruled out. Vercel ensures suitable guarantees for data protection by concluding the Standard Contractual Clauses (SCC). Nevertheless, we would like to point out that the level of data protection in the USA cannot be identical to that in the EU.
Further information can be found in Vercel's privacy policy: https://vercel.com/legal/privacy-policy
7 Disclosure of data to third parties
Your personal data will not be transferred to third parties for purposes other than those listed below. We only pass on your personal data to third parties if:
you have given your express consent to this in accordance with Art. 6 para. 1 sentence 1 lit. a GDPR,
the disclosure pursuant to Art. 6 para. 1 sentence 1 lit. f GDPR is permissible to safeguard our legitimate interests and there is no reason to assume that you have an overriding interest worthy of protection in not disclosing your data,
in the event that there is a legal obligation for the disclosure pursuant to Art. 6 para. 1 sentence 1 lit. c GDPR, and
this is legally permissible and necessary for the processing of contractual relationships or for the implementation of pre-contractual measures with you in accordance with Art. 6 para. 1 sentence 1 lit. b GDPR.

In addition, we also use temporary cookies to optimize user-friendliness, which are stored on your end device for a specified period of time. If you visit our site again to use our services, it is automatically recognized that you have already visited us and which entries and settings you have made so that you do not have to enter them again.
On the other hand, we use cookies to statistically record the use of our website and to evaluate it for the purpose of optimizing our offer for you.

8.2 Legal basis for the use of cookies
The data processed by cookies, which are required for the proper functioning of the website, are necessary to safeguard our legitimate interests and those of third parties in accordance with Art. 6 para. 1 sentence 1 lit. f GDPR.

9 Contents of our website
9.1 Making contact / contact form / telephone
When you contact us (e.g. via contact form, email or telephone), we process and store the personal data you provide (e.g. first name, surname, company, business email address, telephone number and the content of your message). Mandatory information in the contact form is marked accordingly. All other information is voluntary. This data is stored and used exclusively for the purpose of responding to your request or for contacting you and the associated technical administration. The legal basis for processing the data is our legitimate interest in responding to your request in accordance with Art. 6 para. 1 lit. f GDPR. If your contact is aimed at the conclusion of a contract, the additional legal basis for the processing is Art. 6 para. 1 lit. b GDPR. We only process voluntary information - in particular the salutation [AB1] - with your consent in accordance with Art. 6 para. 1 lit. a GDPR. You can revoke this consent at any time with effect for the future. Your data will be deleted after final processing of your request, but at the latest after six months, provided that there are no legal storage obligations to the contrary.
10 Newsletter mailing
10.1 Advertising newsletter
On our website, you are given the opportunity to subscribe to our company's newsletter. Your e-mail address will be collected to register for the newsletter.
We inform our customers and business partners about our offers at regular intervals by means of a newsletter. You can only receive our company's newsletter if
you have a valid e-mail address and
you have registered to receive the newsletter.
For legal reasons, a confirmation e-mail will be sent to the e-mail address you entered for the first time for the newsletter mailing using the double opt-in procedure. This confirmation e-mail is used to check whether you, as the owner of the e-mail address, have authorized the receipt of the newsletter.
When you register for the newsletter, we also store the IP address assigned by your Internet service provider (ISP) to the IT system you are using at the time of registration, as well as the date and time of registration. The collection of this data is necessary in order to be able to trace the (possible) misuse of your e-mail address at a later date and therefore serves our legal protection.
The personal data collected when registering for the newsletter is used exclusively to send our newsletter. Furthermore, subscribers to the newsletter may be informed by e-mail if this is necessary for the operation of the newsletter service or a registration in this regard, as could be the case in the event of changes to the newsletter offer or changes to the technical circumstances. The personal data collected as part of the newsletter service will not be passed on to third parties. You can cancel your subscription to our newsletter at any time. The consent to the storage of personal data that you have given us for the newsletter dispatch can be revoked at any time. There is a corresponding link in every newsletter for the purpose of revoking consent. It is also possible to unsubscribe from the newsletter at any time directly on our website or to inform us of this in another way. After revocation of consent, your personal data stored in connection with the newsletter dispatch will be deleted immediately, provided that there are no legal storage obligations to the contrary.
The newsletter is sent in accordance with Section 7 (2) No. 3 UWG.
The legal basis for data processing for the purpose of sending the newsletter is Art. 6 para. 1 lit. a GDPR.
11 Application procedure
We process the applicant data only for the purpose and within the scope of the application procedure in accordance with the legal requirements. Applicant data is processed to fulfill our (pre-)contractual obligations in the context of the application process within the meaning of Art. 6 para. 1 lit. b. GDPR in conjunction with § 26 BDSG.
The provision of certain personal data (e.g. name, contact information, CV) is required to carry out the application process. Without this information, the application cannot be considered. Further information (e.g. salary expectations, GitHub link, photo) is voluntary and has no influence on the selection process. By submitting their application to us, applicants consent to the processing of their data for the purposes of the application process in accordance with the type and scope set out in this privacy policy.
For applications, we use the online platform of the provider "Personio" (Personio SE, Rundfunkplatz 4, 80335 Munich, Germany). Applicants can enter their data on this platform and transmit it to us in encrypted form. We have concluded an order processing contract with Personio in accordance with Art. 28 GDPR and monitor the service provider and compliance with its measures. Processing takes place exclusively in data centers within the EU. Should a transfer to a third country occur in exceptional cases, this will only take place on the basis of suitable guarantees (e.g. EU standard contractual clauses).
In the event of a successful application, the data provided by the applicants will be processed and stored by us for the purposes of processing the employment relationship.
If the application is unsuccessful, the applicant's data will be deleted. Applicants' data will also be deleted if an application is withdrawn, which applicants are entitled to do at any time. Automated decision-making in accordance with Art. 22 GDPR does not take place. Subject to a justified revocation by the applicants, the deletion takes place after a period of six months so that we can answer any follow-up questions regarding the application and meet our obligations to provide evidence under the General Equal Treatment Act (AGG). In addition, you are entitled to the data subject rights in accordance with the provisions of the GDPR. Further information on this can be found below in this privacy policy.
12 Our activities in social networks
We have our own pages on social networks so that we can communicate with you and inform you about our services. If you visit one of our social media pages, we are jointly responsible with the provider of the respective social media platform within the meaning of Art. 26 GDPR with regard to the processing operations triggered thereby, which concern personal data.
We are not the original provider of these pages, but only use them within the scope of the possibilities offered to us by the respective providers. As a precaution, we would therefore like to point out that your data may also be processed outside the European Union or the European Economic Area. Use may therefore entail data protection risks for you, as it may be more difficult to safeguard your rights, e.g. to information, deletion, objection, etc., and processing in the social networks is often carried out directly for advertising purposes or for the analysis of user behavior by the providers, without us being able to influence this. If user profiles are created by the provider, cookies are often used or the user behavior is assigned directly to your own member profile of the social networks (if you are logged in here).
The described processing operations of personal data are carried out in accordance with Art. 6 para. 1 lit. f GDPR on the basis of our legitimate interest and the legitimate interest of the respective provider in order to communicate with you in a timely manner or to inform you about our services. If you have to give your consent to data processing as a user with the respective providers, the legal basis refers to Art. 6 para. 1 lit. a GDPR in conjunction with Art. 7 GDPR. Art. 7 GDPR.
Social plugins
We also integrate social plugins from the social networks we use (e.g. Facebook, Instagram, LinkedIn, XING) on our website. This allows you to easily interact with our profiles on the respective platforms and share content. When you visit our website, a direct connection to the servers of the respective provider is established. Personal data (such as your IP address) may also be transmitted to third countries, in particular to the USA.
The processing described takes place on the basis of your consent in accordance with Art. 6 para. 1 lit. a GDPR in conjunction with § 25 para. 1 TDDDG.
As we do not have access to the providers' databases, we would like to point out that it is best to assert your rights (e.g. to information, correction, deletion, etc.) directly with the respective provider. Further information on the processing of your data in the social networks and the possibility of exercising your right of objection or revocation (so-called opt-out) is listed below with the respective social network provider we use:
