We process your personal data exclusively in accordance with the provisions of the European General Data Protection Regulation (DS-GVO) and the Federal Data Protection Act (BDSG). Furthermore, we do not process more data than absolutely necessary and, if possible, anonymously.

2. What personal data do we process during your visit to this website?

When you visit the doing hydrogen website, we collect personal data from you in the course of your use of the website:

(1) When you use the website, your access data (URL of the website from which the file was requested; name of the file accessed; date and time of the request; the amount of data transferred; the access status; the internet browser used and the IP address of the requesting computer) are stored.

(2) If you contact us via a contact form on our website or by e-mail, we receive the following information:

  • Personal details (e.g. surname, first name; address; telephone number; e-mail address),
  • other information which you transmit to us in your e-mail or via fields of a contact form,
  • Date and time of your contact.

3. To what extent do we process the above data and for what purposes?

(1) When you visit the doing hydrogen website, we use the IP address and the other data automatically transmitted by your browser to our server under point 2 (1):

  • to be able to provide you with the requested content.
  • to protect ourselves against attacks and to ensure the proper operation of our website. We will only try to find out which person is behind an IP address in cases of illegal attacks.

(2) We store the IP address of your computer after we have shortened it by the last octet – i.e. in anonymised form – in order to analyse the usage behaviour of visitors to our website and thus improve our website. The aforementioned shortening of the IP address for this purpose takes place immediately after collection. We therefore do not collect any personal information about your usage behaviour on our website.

(3) If you contact us via a contact form on our website or by e-mail, we use the personal data mentioned under point 2 (2) to answer your enquiry and to respond to it as far as possible.

4. Are you obliged to provide us with this data? Can you object to its use?

When you visit our website, the information mentioned in point 2 (1) is automatically transmitted from your browser to our server. The transmission of this information is voluntary. Without the provision of this personal data, we cannot show you the requested page.
If you wish to contact us and send us an e-mail or use our contact form for this purpose, the transmission of the information in accordance with point 2 (2) is voluntary. If a contact form contains mandatory fields, these are marked. Without the provision of the personal data required in the individual case, we may not be able to answer your enquiry in the best possible way.

5. What is the legal basis for processing your personal data?

There are several bases for processing your personal data for the purposes mentioned under point 3:

On the one hand, the processing of your personal data is based on your consent (Art. 6(1a) DS-GVO), which you have given us, for example, to receive information about doing hydrogen or about events. Your data will be processed exclusively within the framework of the consent given and only for the purposes to which you have consented.

On the other hand, we process your data in order to fulfil our contractual and non-contractual obligations towards you (Art. 6(1b) DS-GVO). For example:

  • for the purposes of executing the contract;
  • to carry out pre-contractual measures in response to your enquiry.

We process your data if this is necessary for the fulfilment of a legal obligation to which we are subject as the controller (Art. 6(1c) DS-GVO).

Where necessary, we process your personal data beyond the actual performance of contractual or legal obligations in order to protect the legitimate interests of us or third parties (Art. 6(1f) DS-GVO). For example:

  • To ensure the proper operation of our website;
  • to assert claims.

6. Who receives your data?

Your data remains with our company and our affiliated companies. Within the company, those departments will have access to your data that need it to fulfil our legal and contractual obligations. In addition, service providers (especially order processors) and vicarious agents who provide services for us (e.g. IT service providers) have access to your personal data.

Cookies are text files that are stored on your terminal device. The website uses a few technically necessary cookies. These are primarily “session cookies”. These are automatically deleted at the end of your visit. Other cookies remain stored on your terminal device until you delete them. These cookies enable us to recognise your browser on your next visit.

You can set your browser so that you are informed about the setting of cookies and only allow cookies in individual cases, exclude the acceptance of cookies for certain cases or in general and activate the automatic deletion of cookies when closing the browser. If you deactivate cookies, the functionality of this website may be limited. We do not use any other advertising or tracking cookies.

7. How do we secure your personal data?

We use technical and organizational security measures to protect your personal data from accidental or intentional manipulation, loss, destruction or access by unauthorized persons. Our security measures are revised in line with technological developments.

8. Are cookies used on our website?

No cookies are used on this site.

9. How long will your data be stored?

We process and store your personal data as long as it is necessary for our contractual and legal obligations. Once the purpose for which the data was collected has been fulfilled, the data is regularly deleted unless it is necessary to continue processing it for a limited period of time. This includes, for example, the fulfilment of retention periods under commercial and tax law (Commercial Code, Fiscal Code – retention for up to ten years) as well as the preservation of evidence within the framework of the statutory limitation provisions (up to 30 years – regular limitation period is three years).

10. What rights do you have as a data subject?

As a person concerned/affected party, you have various rights:

  • A right to information (Art. 15 DS-GVO).
  • A right to rectification (Art. 16 DS-GVO)
  • A right to erasure (Art. 17 DS-GVO)
  • A right to restriction of processing (Art. 18 DS-GVO)
  • A right to data portability (Art. 20 DS-GVO)
  • A right to object (Art. 21 DS-GVO)
  • A right to lodge a complaint with a supervisory authority (Art. 77 DS-GVO).

Your rights are subject to some legal exceptions. For example, your rights are restricted on the basis of research and statistical purposes (Article 27(2) BDSG) or because of archiving purposes in the public interest (Article 28(2) and (3) BDSG). Other exceptions include: § 34 and 35 BDSG and Art. 17 para. 3 DS-GVO.

You will find detailed information on your right of objection according to Art. 21 DS-GVO at the end in the section “Your rights of objection”.

Furthermore, in the event that the personal data was collected on the basis of your consent, you have the right to revoke this consent at any time. Please note, however, that such a revocation is only effective for the future and that the processing carried out up to that point remains lawful.

Regarding the right to complain to a supervisory authority, we are happy to provide the address of the competent supervisory authority for the company:

The Saxon Data Protection Commissioner
Devrientstraße 5,
01067 Dresden, Germany


PO Box 110132
01330 Dresden.

11. Is there automated decision-making?

In principle, no automated decision-making takes place. If, in some exceptional cases, we do use such a procedure, we will inform you separately in advance, provided this is provided for by law.

12. Information in the event of a change of purpose

If there is a change in the reason for processing your personal data, we will of course inform you immediately.

13. Data protection for minors

This website is intended for persons who are at least 18 years old. We do not wish to collect personal data from persons under the age of 18. Persons under the age of 18 should therefore not submit any personal data on or via this website. If such a person submits personal data via this website, we will delete that data and not process it further once we become aware that they are a minor.

Your rights to object

1. Individual right of objection

In concrete terms, the aforementioned right of objection under Article 21 DS-GVO means that you have the right to object to the processing of your personal data at any time on grounds relating to your particular situation. The prerequisite for this is that the data processing is based on Art. 6(1)(e) DS-GVO (performance of a public task) or on Art. 6(1)(f) DS-GVO (legitimate interests). This also applies to corresponding profiling.

If you object to the processing of your personal data, we will no longer process it. Unless we can demonstrate compelling legitimate grounds for the processing which override your interests, rights and freedoms, or the processing serves to assert, exercise or defend legal claims.

2. Right to object to processing for direct marketing purposes

Pursuant to Art. 21 (2) DS-GVO, you as the data subject have another separate right of objection in the event that your personal data is used for direct marketing. This also applies to profiling, insofar as it is connected with direct advertising. If you exercise this right of objection, we as the responsible party will no longer process your personal data for this purpose.

3. To whom do you address the objection?

The objection does not require a specific form and should preferably be addressed to:

ONTRAS Gastransport GmbH

Data Protection
Maximilianallee 4
04129 Leipzig
