Privacy policy

We take data protection seriously

The protection of your privacy when processing personal data is an important concern for us. When you visit our website, our web servers store the IP of your Internet service provider, the website from which you visit us, the web pages you visit on our site and the date and duration of the visit as standard. This information is absolutely necessary for the technical transmission of the web pages and secure server operation. A personalized evaluation of this data does not take place.

If you send us data via contact form, this data will be stored on our servers in the course of data backup. Your data will only be used by us to process your request. Your data will be treated strictly confidential. It will not be passed on to third parties.

Personal Data

Personal data is data about your person. This includes your name, address and email address. You do not have to disclose any personal data to visit our website. In some cases we need your name and address as well as other information to be able to offer you the requested service.

The same applies in the case that we supply you with information material on request or when we answer your inquiries. In these cases we will always point this out to you. In addition, we only store the data that you have transmitted to us automatically or voluntarily.

When you use one of our services, we usually only collect the data that is necessary to provide you with our service. We may ask you for additional information, but this is voluntary. Whenever we process personal data, we do so in order to provide you with our service or to pursue our commercial objectives.

Automatically stored Data

Server log files

The provider of the pages automatically collects and stores information in so-called server log files, which your browser automatically transmits to us. These are:

  • Date and time of the request
  • Name of the requested file
  • Page from which the file was requested
  • Access status (file transferred, file not found, etc.)
  • Web browser and operating system used
  • Complete IP address of the requesting computer
  • Amount of data transferred

This data is not merged with other data sources. The processing is carried out in accordance with Art. 6 (1) f GDPR on the basis of our legitimate interest in improving the stability and functionality of our website.

For reasons of technical security, in particular to defend against attempted attacks on our web server, we store this data for a short period of time. It is not possible for us to draw conclusions about individual persons on the basis of this data. After seven days at the latest, the data is anonymized by shortening the IP address at domain level, so that it is no longer possible to establish a link to the individual user. The data is also processed anonymously for statistical purposes; it is not compared with other data or passed on to third parties, even in part. Only in the context of our server statistics, which we publish every two years in our activity report, is a presentation of the number of page views made.


When you visit our website, we may store information on your computer in the form of cookies. Many cookies contain a so-called cookie ID. A cookie ID is a unique identifier of the cookie. It consists of a string of characters by which Internet pages and servers can be assigned to the specific Internet browser in which the cookie was stored. This enables the visited Internet pages and servers to distinguish the individual browser of the data subject from other Internet browsers that contain other cookies. A specific Internet browser can be recognized and identified via the unique cookie ID.

Through the use of session cookies, the responsible party can provide the users of this website with a user-friendly service that would not be possible without the cookie setting. Without consent, we only use technically necessary cookies on the legal basis of legitimate interest pursuant to Art. 6 (1) f GDPR.

We only use personal cookies to improve our website or for marketing/advertising purposes with your consent. On your first visit, you can voluntarily agree to tracking or analysis via the cookie banner that appears. If necessary, your data will be passed on to partners or third-party providers. Only if you explicitly agree to this will these cookies be stored, the legal basis is then your consent in accordance with Art. 6 para. 1 a GDPR.

You can change your settings for the use of cookies here at any time.

Web analytics Matomo

This website uses the open source web analytics service Matomo. Matomo uses technologies that enable cross-page recognition of the user to analyze user behavior (e.g. cookies or device fingerprinting). The information collected by Matomo about the use of this website is stored on our server. The IP address is anonymized before storage.

With the help of Matomo, we are able to collect and analyze data about the use of our website by website visitors. This allows us to find out, among other things, when which page views were made and from which region they come. We also collect various log files (e.g. IP address, referrer, browsers and operating systems used) and can measure whether our website visitors perform certain actions (e.g. clicks, purchases, etc.).

The use of this analysis tool is based on Art. 6 para. 1 lit. f DSGVO.

We host Matomo exclusively on our own servers, so that all analysis data remains with us and is not passed on.

If you do not agree to the storage and use of your data, you can deactivate the storage and use here. In this case, an opt-out cookie will be stored in your browser, which prevents Matomo from storing usage data. If you delete your cookies, this will have the effect that the Matomo opt-out cookie will also be deleted. The opt-out must be reactivated when you visit this website again.


We have integrated YouTube videos into our online offer, which are stored on and can be played directly from our website. These are all integrated in "extended data protection mode", which means that no data about you as a user is transmitted to YouTube if you do not play the videos. Only when you play the videos, the data mentioned in paragraph 2 are transmitted. We have no influence on this data transmission.

By visiting the website, YouTube receives the information that you have accessed the corresponding sub-page of our website. In addition, the data listed in the passage "Description of data processing on the website/app and legal basis for processing" is transmitted. This takes place regardless of whether YouTube provides a user account via which you are logged in or whether no user account exists. If you are logged in to Google, your data will be directly assigned to your account. If you do not want the assignment with your profile at YouTube, you must log out before activating the button. YouTube stores your data as usage profiles and uses them for the purposes of advertising, market research and/or demand-oriented design of its website. Such an evaluation is carried out in particular (even for users who are not logged in) to provide needs-based advertising and to inform other users of the social network about your activities on our website. You have the right to object to the creation of these user profiles, whereby you must contact YouTube to exercise this right.

Further information on the purpose and scope of data collection and its processing by YouTube can be found in the privacy policy. There you will also find further information on your rights and setting options to protect your privacy:

Google Doubleclick

Doubleclick by Google uses cookies to present you with ads that are relevant to you. In the process, a pseudonymous identification number (ID) is assigned to your browser in order to check which ads were displayed in your browser and which ads were called up. The legal basis is Art. 6 para. 1 p. 1  a) GDPR The cookies do not contain any personal information. The use of DoubleClick cookies only enables Google and its partner websites to serve ads based on previous visits to our website or other websites on the Internet. The information generated by the cookies is collected by Google and stored on a server in the USA.


We have implemented technical and administrative security measures to protect your personal data against loss, destruction, manipulation and unauthorized access. All our employees and service providers working for us are bound by the applicable data protection laws.

Whenever we collect and process personal data, it is encrypted before it is transmitted. This means that your data cannot be misused by third parties. Our security measures are subject to a continuous improvement process and our data protection statements are constantly being revised. Please make sure that you have the latest version.

Rights of the data subject

You have a right to information, correction, deletion or restriction of the processing of your stored data at any time, a right to object to the processing as well as a right to data portability and to lodge a complaint in accordance with the requirements of data protection law.

Right of access by the data subject:

You can request information from us as to whether and to what extent we process your data.

Right to retification:

If we process your data that is incomplete or incorrect, you can request that we correct or complete it at any time.

Right to erasure (right to be forgotten):

You can demand that we erase your data if we process it unlawfully or if the processing disproportionately interferes with your legitimate interests in protection. Please note that there may be reasons that prevent immediate erasure, e.g. in the case of legally regulated retention obligations.

Irrespective of the exercise of your right to erasure, we will immediately and completely erase your data, insofar as there is no legal or statutory obligation to retain data in this respect.

Right to restriction of processing:

You may request us to restrict the processing of your data if

  • you dispute the accuracy of the data, for a period of time that allows us to verify the accuracy of the data.
  • The processing of the data is unlawful, but you refuse erasure and instead request restriction of the use of the data,
  • we no longer need the data for the intended purpose, but you still need this data to assert or defend legal claims, or
  • you have objected to the processing of the data.
Right to data portability:

You may request that we provide you with the data you have provided to us in a structured, commonly used and machine-readable format and that you may transfer this data to another controller without hindrance from us, provided that

  • we process this data on the basis of a revocable consent given by you or for the performance of a contract between us, and
  • this processing is carried out with the aid of automated procedures.

If technically feasible, you may request us to transfer your data directly to another controller.

Right to oject:

If we process your data for legitimate interest, you can object to this data processing at any time; this would also apply to profiling based on these provisions. We will then no longer process your data unless we can demonstrate compelling legitimate grounds for the processing that override your interests, rights and freedoms, or the processing serves the assertion, exercise or defense of legal claims. You may object to the processing of your data for the purpose of direct marketing at any time without giving reasons.

Right of appeal:

If you are of the opinion that we are violating German or European data protection law in the processing of your data, please contact us so that we can clarify any questions. Of course, you also have the right to contact the supervisory authority responsible for you, the respective state office for data protection supervision.

If you wish to assert any of the aforementioned rights against us, please contact our data protection officer. In case of doubt, we may request additional information to confirm your identity.

3. For what purposes and on what legal basis are the data processed?

We process your data in accordance with the provisions of the General Data Protection Regulation (GDPR) and the Federal Data Protection Act 2018, in its current version:

    Processing of your data is for the purpose of meeting various legal obligations, e.g. required by trading or tax legislation
  • To safeguard legitimate interests (Art. 6 para. 1 lit.f GDPR):
    On the basis of a weighing of interests, data processing may take place beyond the actual fulfillment of the contract in order to safeguard legitimate interests of us or third parties. Data processing for the protection of legitimate interests is carried out in the following cases, for example:
    - advertising or marketing (see No. 4)
    - measures for business management and the further development of services and products
    - maintain a group-wide customer database to improve customer service

  • Within the scope of your consent (Art. 6 para. 1 lit.a GDPR):
    If you have given us your consent to process your data, e.g. to send you our newsletter, to publish photos, competitions, etc. We will not use your data for any other purpose.

4. Processing of personal data for advertising purposes

You may at any time object to the use of your personal data for advertising purposes in whole or for individual measures without incurring any costs other than the transmission costs according to basic tariffs.

In Germany we are entiteled under the legal requirements of Art. 7 (3) UWG (law against unfair competition), to use the e-mail address you provided when concluding the contract for direct advertising for our own similar goods or services. We will provide you with product recommendations regardless of whether you have subscribed to a newsletter. If you do not wish to receive such recommendations by e-mail from us, you may object to the use of your address for this purpose at any time without incurring any costs other than the transmission costs according to the basic tariffs. A text message is sufficient for this purpose. Of course, every e-mail we send to you always contains an unsubscribe link.

5. Who receives my data?

If we use a third party service provider for order processing, we will still be responsible for protecting your data. All third parties are contractually obliged to treat your data confidentially and to process it only as part of the provision of their services. The third parties appointed by us will only receive the data necessary to carry out their required services. These are e.g. IT service providers that we need for operation and security of our IT system as well as advertising and mailing list providers for our own advertising campaigns.

Your data will be processed in our customer database. The customer database improves the data quality of existing customer data (duplicate cleanup, address unknown / deceased, address changes), and allows enrichment with data from public sources.

This data is made available in the group companies insofar as this is neccessary for the processing of the contract. Customer data is stored separately for each company, whereby we as parent company act as a service provider for the individual participating companies of the HUBER group. Further recipients of the data may be the participating WTE Wassertechnik GmbH, which is part of the EVN group.

In the event of a legal obligation and in the context of legal prosecution, authorities and courts as well as external auditors may be recipients of your data. In addition, insurances, credit agencies and service providers maybe recipients of your data for the purpose of initiating and fulfilling contracts.

6. How long will my data be stored?

We process your data until the termination of the business relationship or until expiry of the applicable statutory retention periods (for example, in line with commercial law, the tax law, or the Working Hours Directive); in addition, until the termination of any legal disputes in which the data is required as evidence.

7. Is personal data transmitted to a third country?

In principle, we do not transmit any data to a third country. Transmission in individual cases will only take place on a case-by-case basis in accordance with the agreement by the European Commission, standard contractual clauses, appropriate safeguards or where you have given your express consent.

8. What privacy rights do I have?

You have the right to information, correction, deletion or restriction of the processing of your stored data, a right to object to the processing as well as a right to data portability and to a complaint in accordance with the requirements of data protection law.

If you wish to exercise one of the above mentioned rights, please contact our data protection officer. If in doubt, we may request additional information to confirm your identity.

9. Am I obliged to provide data?

The processing of your data is neccessary to conclude or fulfill your contract with us. If you do not provide us with this data, we will generally have to refuse to enter into the contract or will no longer be able to perform an existing contract and will therefore have to terminate it. However, you are not obliged to give your consent to data processing with regard to data that is not relevant or legally required for the fulfillment of the contract.
