2. Legal bases of the processing

The processing of personal data requires a legal basis, which we would like to present to you below.

Article 6(1)(a) of the EU General Data Protection Regulation (GDPR) serves as the legal basis for the processing of personal data for which we obtain the consent of the data subject. Article 6(1)(b) GDPR serves as the legal basis for the processing of personal data required for the fulfilment of a contract to which the data subject is a party. This also includes processing operations that are necessary for the performance of pre-contractual measures.

Insofar as the processing of personal data is necessary to fulfil a legal obligation to which our company is subject, Article 6(1)(c) GDPR serves as the legal basis.

If the processing is necessary to safeguard a legitimate interest of our company or a third party and if the interests, fundamental rights and freedoms of the data subject do not outweigh the former interest, Article 6(1)(f) GDPR serves as the legal basis for the processing. The legitimate interest of our company lies in the performance of our business activities and in analysing, optimising and maintaining the security of our online offering.

3. Rights of the person concerned

You have a right to information about the personal data we have stored about you. In particular, you can request information about the processing purposes, the category of personal data, the categories of recipients to whom your data has been or will be disclosed, the planned storage period, the origin of your data if it has not been collected by us, as well as the existence of automated decision-making including profiling and, if applicable, meaningful information about its details.

In accordance with the statutory provisions, you also have the right to rectification of inaccurate data, restriction of processing, data portability and erasure of your personal data. To do this, send us an e-mail with the subject “Data protection”.

You also have the right to lodge a complaint with a data protection supervisory authority if you are of the opinion that the processing of your personal data is in breach of the statutory provisions.

For reasons arising from your particular situation, you can object at any time to the processing of personal data concerning you by us, which is carried out on the basis of Art. 6 para. 1 lit. e or f; this also applies to profiling based on these provisions (Art. 21 GDPR). If the legal requirements are met, we will then no longer process your personal data.

In the case of direct advertising, you have the right to object at any time to the processing of personal data concerning you for the purpose of such advertising; this also applies to profiling insofar as it is associated with such direct advertising.
If you object, your personal data will no longer be processed for these purposes.

If you have given your consent, you have the right to withdraw your consent at any time. This does not affect the legality of the processing carried out on the basis of the consent until the revocation.

If you exercise one of the aforementioned rights as a data subject, we will process your personal data collected in this context in order to respond to your enquiry. Your personal data is processed to fulfil a legal obligation.

In the event of an objection, we will no longer process your personal data unless we can demonstrate compelling legitimate grounds for the processing of this data which override your interests, rights and freedoms or your personal data serves the establishment, exercise or defence of legal claims.

4. Storage period of the personal data

Unless we have provided storage information on the specific points, the following applies: We store personal data for the duration of the respective statutory retention period or as long as the purpose of the collection exists. After the retention period has expired, the data is routinely deleted, unless it is necessary for the initiation or fulfilment of a contract. If the user’s data is not deleted because it is required for other and legally permissible purposes, its processing is restricted as far as possible. Accordingly, the data will be blocked where possible and not processed for other purposes. This applies, for example, to user data that must be retained for commercial or tax law reasons.

II. Contractual processing

When you enter into a contractual relationship with us, we generally collect the following data: Title, first and last name, email address, address, telephone/mobile phone number, information necessary for the performance of the contract.

We require this data so that we can identify you as a contractual partner, fulfil the contract, contact you and for invoicing purposes. The data processing takes place at your / our request or order and is necessary for the purposes mentioned for the mutual fulfilment and obligation arising from the contractual relationship.

We may also process data on the basis of a legitimate interest, e.g. in the assertion of or defence against claims arising from the contractual relationship. The personal data collected will be stored until the end of the contractual relationship and then deleted, unless we are obliged to store it for a longer period of time in accordance with legal obligations due to tax and commercial law retention and documentation obligations (from HGB, StGB or AO).

III. Data processing in the context of the website

1. Log files, hosting

The server statistics will automatically file such data which the browser will transmit to us within the scope of our legitimate interest of the analysis and for security reasons (so called „logfiles“).

In particular this contains the following data:

– Language and version of the browser software
– used operating system and its interface
– Referrer URL (prior visited site)
– Hostname of the accessing computer (IP-Address)
– Date and time of the server request
– Time zone difference to Greenwich Mean Time (GMT)
– Content of the request (concrete site)
– transmitted amount of data
– Status of access/ HTTP-Statuscode.

As a rule, we cannot assign this data to specific persons. This data is not merged with other data sources. The data is also deleted within 7 days after a statistical analysis. Data whose further retention is required for evidentiary purposes is excluded from deletion until the respective incident has been finally clarified.

We make use of hosting services. These are used to provide infrastructure and platform services, computing capacity, storage space and database services, security services and technical maintenance services in order to maintain the operation of this online offering.

In doing so, we or our hosting provider process inventory data, contact data, content data, contract data, usage data, meta and communication data of customers, interested parties and visitors to this online offering on the basis of our legitimate interests in the efficient and secure provision of this online offering.

2. Contacting

When you contact us by e-mail or via a contact form, your details will be stored by us in order to answer your questions.

Your data will not be passed on to third parties unless applicable data protection regulations justify a transfer or we are legally obliged to do so. You can revoke your consent at any time with effect for the future. In the event of cancellation, your data will be deleted immediately, unless there is a legal exception for further processing. Your data will otherwise be deleted once we have processed your enquiry or the purpose of storage no longer applies and there are no other legal exceptions to the contrary.

3. Cookies

Cookies are small text files that are stored on your computer and through which certain information flows to the location that sets the cookie. They are used to make the website more user-friendly and effective and/or to make it easier for you to navigate our website. We only set cookies that are not absolutely necessary with your consent. You can revoke this consent for future use at any time.

Consent is voluntary and you can also use our website without accepting cookies. You can also configure your browser settings according to your wishes and, for example, refuse to accept third party cookies or all cookies or delete cookies that have already been saved. If you do not accept cookies, please note that our website may not function properly in this case. Unless we provide other information on the individual topics mentioned in this privacy policy or in the cookie banner, the lifespan of cookies is 24 months.

You can find out which function on our website sets cookies in the individual function descriptions in our privacy policy and in the cookie banner.

IV. Information to contractual partners

If you, as our contractual partner, have concluded a contract for our services, we will offer you further information about our own similar services via the e-mail address sent to you when the contract was concluded (Section 7 III UWG). You can object to this mailing at any time.

These mailings are sent on the basis of our legitimate interest in advertising.

V. Forwarding of the data: General and contractual purpose

We pass on data to third parties if this is necessary for the fulfilment of the contract and / or if we are legally obliged and / or authorised to do so in individual cases. The data is typically passed on to contracted service providers, including hosting, operation, maintenance and support of IT systems, communication systems and disposal under certain circumstances. In addition, your data may also be transferred to postal or delivery services, your bank, tax advisors/auditors and lawyers.

VI. Forwarding of the data: Tools in the context of the operation of the website and online services

We do not use any external service providers for the analysis, optimisation and economic operation of the online offer.

If your data is to be used for other purposes, we will inform you in advance and only use the data if you have expressly given your prior consent.

VII. Our social media presence

You can find us under online presences within social networks and platforms. We would like to use these presences to communicate with our customers, interested parties and users active there and to inform them about our services and our company in this way.

The processing of the personal data of users active there is based on our legitimate interests in communicating and providing information to and with users. If users have given their consent to data processing within the framework of the respective social platform, the processing takes place on the basis of this consent.

If you visit one of our social media sites, we are jointly responsible with the operator of the social platform for the data processing operations triggered during this visit. In principle, you can assert your rights (information, rectification, erasure, restriction of processing, data portability and complaint, see the following point “Rights of the data subject”) both against us and against the operator of the respective social platform.

We would like to point out that, despite the joint responsibility, we do not have full influence on the data processing operations of the social platform and may forward the rights request to the respective operator in order to better process the rights of the data subject. Our options generally depend on the company policy of the respective provider.

Our information on storage can be found below. We have no influence on the storage period of your data that is stored by the operator of the social platform for its own purposes. For details, please contact the operators of the social networks directly (e.g. in their privacy policy, see below).

Depending on the social platform named below, user data processing may also take place outside the European Union. EU standard contractual clauses have been agreed with the US companies or they are certified under the Data Privacy Framework (DPF), so that we have taken possible measures to ensure compliance with European data protection law.

As a rule, user data is processed by the platforms for market research and advertising purposes. For example, user profiles can be created from user behaviour and the resulting interests of users. The user profiles can in turn be used, for example, to place adverts inside and outside the platforms that presumably correspond to the interests of the users. For this purpose, cookies are usually stored on the user’s computer, in which the user’s usage behaviour and interests are stored. Data can also be stored in the user profiles independently of the devices used by the users. This occurs in particular if the users are members of the respective platforms and are logged in to them.

For a detailed presentation of the respective processing and the objection options, we refer to the information of the providers linked below.
