General Information

Pursuant to our statutory obligations, we would like to inform you about the collection and use of your personal data.

When you use our website, personal data about you will be collected. This may happen by you entering the data yourself, for example your e-mail address. But our system also collects your data automatically, for example whenever you visit our website. This happens irrespective of the device or the software that you use to visit our website.

All data that you enter in our app is provided voluntarily; there are no disadvantages to you if you do not provide data. But without certain data, we are unable to provide services or to conclude contracts. Whenever such information is necessary, we will point it out to you.

On this website, the user’s personal data is only collected within the framework of the existing data-protection law, in particular the General Data Protection Regulation (GDPR). The legal terms used in the text are defined in Art. 4 of the GDPR.

The GDPR allows data processing in three cases in particular:

  • in accordance with Art. 6 para. 1 (a) and 7 GDPR, when you have consented to us processing your data; in this Privacy Policy and in the cases of consent pursuant to Art. 4 no. 11 GDPR, we will inform you in detail and each time for what purposes and under what circumstances your data will be processed by us;
  • in accordance with Art. 6 para. 1 (b) GDPR, when processing your personal data is necessary for negotiating, concluding or performing a contract;
  • in accordance with Art. 6 para. 1 (f) GDPR, if the balancing of interests leads to the conclusion that the processing is necessary to protect our legitimate interests; this means in particular our interests to analyse, optimise and secure the offers on our website – meaning primarily the analysis of user behaviour, setting up profiles for advertisement purposes and storage of access data as well as the use of third-party providers.

Inventory data

We collect inventory data insofar as it is necessary for the establishment, content or modification of a contractual relationship (also free of charge) between us and the user. This may include: Customer data (e.g. name, address), contact data (e.g. e-mail address, telephone number), performance data (e.g. ordered service, term, fee). When establishing the user relationship, we will request this data from you (e.g. name, address and e-mail address) and also inform you of the extent to which the information is required in each case in order to establish the user relationship.

Usage data

We further collect usage data to enable the user’s use of the services on our website. This may include: Usage data (e.g. web pages or areas accessed, duration of visit, interest in services), content data (e.g. data entered or uploaded by you, texts, images, sounds, videos), metadata (e.g. identity of your device, location, IP address).

We will only aggregate usage data if and to the extent necessary for billing purposes. Otherwise, we will only create usage data pseudonymously and only if you have not objected to this. You can send this objection at any time to the address given in the imprint or to the responsible person named in this privacy policy.

The legal basis for this data processing is, on the one hand, our legitimate interests pursuant to Art. 6 para. 1 lit. f DSGVO in the analysis of the website and its use, and, if applicable, also the legal permission to store data as part of the initiation of a contractual relationship pursuant to Art. 6 para. 1 lit. b DSGVO.



Our website is made available for retrieval on the Internet by a service provider (provider or hoster). For this purpose, we use the service of Raidboxes GmbH, Hafenstraße 32, 48153 Münster. We have concluded an order processing contract with our provider. Accordingly, our provider is obliged to process your data only on our behalf and according to our instructions. Further information on data processing by our provider can be found in its privacy policy at

https://raidboxes.io/datenschutzerklaerung/. The legal basis for this data processing is, on the one hand, our legitimate interests pursuant to Art. 6 Para. 1 lit. f DSGVO in the provision and use of our website on the Internet and, where relevant, also the legal permission to store data as part of the initiation of a contractual relationship pursuant to Art. 6 Para. 1 lit. b DSGVO.

Each time you use this website, our provider processes information, the so-called server log files, which are automatically transmitted by your browser each time you call up websites on the Internet. These are:

  • Your IP address
  • Type and version of your browser
  • Host name
  • time of visit
  • the website from which you visited our website
  • name of the website you visited
  • exact time of the call and
  • the amount of data transferred

This data is only used for statistical purposes and does not allow us to identify you as a user.

Initial contact through electronic inquiry

If you contact us electronically (e.g. e-mail, fax, telephone, messenger, etc.), we store and process the data you have provided us with (e.g. name, contact information, content of the inquiry). The legal basis for this is our legitimate interest in effective customer communication pursuant to Art. 6 Para. 1 lit. a DSGVO and, insofar as it concerns a request to enter into or fulfill a contract, also Art. 6 Para. 1 lit. b DSGVO.
We will only pass on this data to third parties insofar as it is necessary (according to Art. 6 Para. 1 lit. b DSGVO) for the fulfillment of the contract, this corresponds to the overriding interest in effective performance (according to Art. 6 Para. 1 lit. f DSGVO) or your consent (according to Art. 6 Para. 1 lit. a DSGVO) or another legal permission or obligation exists.
You can request information about the purpose of processing, origin and, if applicable, recipients of your personal data from us free of charge at any time. Furthermore, you can assert the correction, the deletion and the restriction of the processing of your personal data. You may object to the (further) processing of your data at any time and have a right to data portability as well as a right to lodge a complaint with the competent supervisory authority.
In principle, your data will only be stored for as long as required by the purpose of the respective data processing. Further storage is mainly considered if this is still necessary for legal prosecution or for legitimate interests or if there is a legal obligation to still store the data (e.g. tax retention periods, statute of limitations).


Where we ask for your consent to process your data, we will inform you in clear language and easily accessible about the cases for which you give your consent. Any consent we ask for is voluntary, any benefit you wish to obtain by giving consent can be obtained without the consent, just ask us.

For any consent, you have the right to revoke any consent given to us to process your personal data at any time. This can be done by an informal message, for example, via our contact form, an email to the email address provided in the imprint or an unsubscribe link (if offered by us). Your revocation does not affect the lawfulness of the data processing carried out until then.

Duration of storage

In principle, your data will only be stored for as long as the purpose of the respective data processing requires. Further storage is mainly considered if this is still necessary for legal prosecution by us or for our other legitimate interests.
For your inventory data that was required for the fulfillment of a contractual relationship (also free of charge), this means that we store it until the complete fulfillment or termination of the contractual relationship plus the limitation period (which is generally 2 or 3 years) plus an appropriate surcharge for any interruption of the limitation period.
For your usage data collected on the occasion of your use of the website, this means that we will only store it for as long as this is still necessary for the proper functioning of our website and our legitimate interest is sufficient. In the first instance, we will only store statistical data in pseudonymized form.
In addition, we still store your data insofar as we are legally obligated to do so. These are in particular the tax retention periods, which are generally 6 or even 10 years.


More then essential Cookies

Upon opening the website, we have asked you to consent to the storing of certain cookies which will be placed while you visit our website. Based on your consent pursuant to Art 6 para. 1 (a) GDPR, our website thus uses cookies, so that our offer can be used in a better, more effective and more secure way.
Cookies are text files that are stored on your computer and which store certain data about your user behavior on our page, so that certain features or offers can be made available to you based on your previous use. These can be “session cookies”, which are automatically deleted when you leave our website. Other cookies are stored on your computer permanently until you delete them. That allows us to recognize your browser when you visit our website again and to provide you with features or offers according to your previous usage.

Your browser allows you to prevent the use of cookies in general or in specific cases. Please check the instructions for your browser to find out more about this.


In order to obtain your consent to store certain cookies on your device and to document this in line with data protection law, and in line with our legal obligations under Art. 6 para. 1 sentence 1 (c) GDPR and our legitimate interest in accordance with Art. 6 para. 1 (f) GDPR, we use the Cookie Consent Manager “Borlabs Cookie“ provided by Borlabs – Benjamin A. Bornschein, Georg-Wilhelm-Str. 17, 21107 Hamburg, Germany.
Borlabs Cookie only places cookies that are technologically necessary. When you open our website, the following data will be sent to Borlabs Cookie: your consent or the withdrawal of your consent for placing cookies, a cookie placed on your browser by Borlabs Cookie, the duration and version of the cookie, domain and path of the WordPress website and the UID. The UID is a randomly generated ID and no personal information.
Borlabs Cookie processes no personal data. If you want to withdraw the consent to place certain cookies, simply delete the cookie in your browser. When you re-enter/reload the website, you will be asked for your consent to place cookies again.
You can find detailed information about the privacy policy of Borlabs Cookies at: https://de.borlabs.io/datenschutz/

User rights

You can request information from us at any time and free of charge about the personal data we have stored about you. In this case, identification of your person is required to prevent misuse.

Deletion, correction, restriction

You can request us to correct (also by supplementing) incorrect data at any time as well as to restrict its processing or also to delete your data. This applies in particular if the purpose of processing has expired, a required consent has been revoked and no other legal basis exists or our data processing is unlawful. We will then immediately correct, block or even delete your personal data within the legal framework.



Data transfer

You can request us to transfer the data stored about you in machine-readable form.


Insofar as you feel that your rights have been violated by our data processing, you can file a complaint with the competent supervisory authority (you can find a list of authorities here).

Change of the privacy policy

If a change to the privacy policy becomes necessary for legal or factual reasons, we will update this page accordingly. In doing so, no changes will be made to the consents given by the user.

Data inputs


When you enter data on our website, whether on a contact form, on the occasion of registration, logging in or for payment purposes, the website on which you enter the data is encrypted. This prevents third parties from reading what data you enter. You can recognize the encryption by the lock symbol in your browser and by the fact that the address line begins with “https” instead of just “http”.

General contact form

If you fill out a contact form or send us an e-mail or other electronic message, your information will be stored for processing the request, possible follow-up questions or related questions and used only in the context of the request.

The input of your data is encrypted, so that third parties cannot read your data during the input even if they have access to the network (e.g. in unprotected public W-LANs).

The basis for this storage is our legitimate interest in communicating with interested users according to Art. 6 para. 1 lit. f DSGVO and, in the case of contract inquiries, also the storage of contract data according to Art. 6 para. 1 lit. b DSGVO.

Your data will remain stored as long as it is required for the processing of the request, in particular the storage is still necessary for the fulfillment/processing of the contract, for legal prosecution by us or for our other legitimate interests or we are required by law to retain your data (e.g. within the framework of tax retention periods).

Callback request

On our service page you can order a callback by one of our service staff. We ask here
– Your first name, because we like to address you personally,
– your telephone number, so that we can call you back, and
– your e-mail address, because we will send you e-mail confirmations of your inquiries.

The input of your data is encrypted, so that third parties cannot read your data during the input.

The basis for this storage is our legitimate interest in communication with users who are themselves interested in it according to Art. 6 para. 1 lit. f DSGVO and, in the case of contract inquiries, also the storage of contract data according to Art. 6 para. 1 lit. b DSGVO.

Your data will be stored for 6 months after completion of the processing, so that in case of later service requests, the service results already compiled can be accessed.

Rating portals

Proven Expert

We use the evaluation portal Proven Expert of Expert Systems AG, Quedlinburger Str. 1, 10589 Berlin, Germany, as part of our legitimate interest in a technically flawless online offer and its economically efficient design and optimization pursuant to Art.6 para. 1 lit.f DSGVO.
