General data protection statement

This privacy policy is directed at the users of our website. It is intended to provide information about the nature, scope and purpose of the collection and use of personal data by us, the responsible controller of

CytoTools AG

(details and contact see imprint)

We take data protection seriously and treat your personal data confidentially and in accordance with the statutory regulations, in particular with the European General Data Protection Regulation (GDPR) and the German Federal Data Protection Act (BDSG).

Because changes may be made to this data protection declaration as a result of new technologies, the constant further development of this website and the updating of the legal basis, we recommend that you reread the data protection declaration at regular intervals. (You can check at the very end of this data protection statement to see when we last updated this text).

Definitions of the terms used here (e. g. "personal data" or "processing") can be found in article 4 GDPR.


Basic information on the handling of your data

The following principles apply to our handling of your personal data:

  • As a matter of principle, we do not pass on your data to third parties.

  • All personal data collected by us is subject to the rights of the data subject, which we would like to expressly point out to you at this point and which are explained in detail further down on this page. (See section Rights you have to your data.)

    You can find out what personal data we collect, how it is transferred, for what purposes we collect it and how long we store it in the following sections of this data protection statement.


Data transmission

The transmission of data to and from our site is carried out exclusively by means of a secure, encrypted connection via the so-called "HyperText Transfer Protocol Secure" (HTTPS). This prevents third parties from reading the data transfer, understanding the content, using it for their own purposes or falsifying it. You can recognise the use of such transport encryption by a lock symbol in the address line of your Internet browser.

However, we would like to point out that data transmission on the Internet can have security gaps. Therefore, a guaranteed protection of data against access by third parties is not possible.


Access data

The website provider collects data on all accesses to the website on our behalf and due to our legitimate interest as the website operator and stores this data as so- called "server log files" on the website's Internet server. The following data is logged in the process:

  • Visited website

  • Date and time at the time of access

  • Amount of data sent

  • Source/reference from which you reached the page

  • Browser used

  • Operating system used

  • IP address used

    We cannot assign this data to specific persons. A combination of this data with other data sources is not made in principle.

    Our website provider stores server log files for a maximum of 60 days and then deletes them automatically. The data is stored for security reasons, e. g. to be able to clarify cases of abuse. If we are obliged to retain data for legal reasons
    (e. g. for the purpose of preserving evidence), they are exempt from deletion until the incident has been finally clarified. There is a so-called "data processing agreement" between our website provider based in Germany and us in accordance with article 28 ff. GDPR, which legally secures the data protection compliant processing of your data.



This website does not use so-called "cookies" for advertising or tracking purposes. Such cookies are not transmitted to visitors' browsers by our server or by third- party servers.

When calling up individual web pages, however, a technically necessary cookie is set, which is automatically deleted after your visit to our pages when you close the browser. According to the current legal situation, no consent by visitors is required before any technically necessary cookies are set. (See ruling of the German Federal Court of Justice (BGH), May 2020).

However, you can set your browser so that you are always informed about the setting of cookies. You can thus allow cookies only in individual cases, exclude the acceptance of cookies for certain cases or generally, as well as activate the automatic deletion of all cookies when closing the browser. (In this case, technically necessary cookies will also be blocked, the function of our website will be limited.)

You can find out what you need to set in your browser in the instructions provided by your Internet browser provider (Chrome, Edge, Firefox, Opera, Safari, etc.).


Interested parties that contact us

If you contact us using the contact options offered (e-mail address, telephone number or contact form), we will store your details so that we can use them to process and respond to your enquiry.

Personal data in the sense of this data protection statement could be your telephone number or your e-mail address. In addition, you could provide us with further personal data such as first and last names, postal addresses, your own websites, etc. as part of the exchange of information (for example, as part of an e- mail signature used by you).

We store all these personal data for up to three years for the purpose of contact maintenance and subsequent contact and will delete them afterwards in any case without further action by you, unless you send us an informal request for deletion or correction of your personal data beforehand. (See also the section on the rights you have to your data.)


Rights you have to your data

As a data subject, you have the right to request information free of charge about what personal data has been stored about you (right of access). You also have the right to have inaccurate data corrected and to restrict the processing or deletion of your personal data. If applicable, you could also exercise your right to data portability. You also have the right to object to future processing of your data.

Should you assume that your data has been processed unlawfully in contradiction to this data protection statement or fundamentally in the sense of the GDPR, you can file a complaint with the supervisory authority in charge, Der Hessische Beauftragte für Datenschutz und Informationsfreiheit.


Erasure and rectification of data

Unless your request conflicts with a legal obligation to retain data (e. g. data retention or statutory retention obligations), you have a right to have your data deleted (right to be forgotten). We will delete data stored by us if it is no longer necessary for its intended purpose and if there are no legal requirements for its retention.

If we are not allowed to carry out the deletion because the data is required for permissible legal purposes, the data processing will be restricted; in this case, we will block the data and will not process it for purposes other than those required by law.

The same applies to the rectification of data that is not (no longer) correct. You can request a correction at any time.


Right of objection

Users of this website can exercise their right to object to the processing of their personal data for the future at any time.

If you wish to request rectification, blocking, erasure or access to the personal data stored about you or if you have any questions regarding the collection, processing or use of your personal data or if you wish to revoke any consent given, you can informally send us your request in writing, electronically or verbally. The fastest and the safest way for your request is to use the following e-mail address:
