Purposes and foundations in law

Protocol data

Each time you access a website, your Internet browser sends our web server information automatically for technical reasons ('protocol data'). We save some of this information in log files, such as

  • Date accessed
  • Time accessed
  • URL of referring website
  • File fetched
  • Volume of data transferred
  • Browser type and version
  • Operating system
  • IP address

We only analyse protocol data in principle to rectify problems when operating our website or sorting out security incidents.

As well as protocol data, we may also need to gather personal data to rectify problems or as evidence in the event of security incidents. We then process protocol data as allowed in law.

We process it under Art. 6 para. 1(f) GDPR; our interest is in providing, safeguarding and optimising the website.

Contact form

You can contact us using the contact form. Some of the data entered there is required to enable us to communicate with you and deal with what is concerning you. These are marked as mandatory fields. Other data you send us helps us talk to you personally or deal with things more promptly.

We process this under Art. 6 para. 1 (b) GDPR.

Applicant management

You can use the application form both to apply of your own accord and apply for one of the situations vacant posted at our company. We need the data you input here to start establishing an employment relationship, communicate about it and process your case.

We process this data under Art. 6 para. 1 (b) GDPR in conjunction with § 26 para. 1 BDSG [Federal Data Protection Law].

Suppliers and customers

We use contact and communications data and other relevant personal data of our suppliers and customers insofar as they or their staff are natural persons. We process this data to handle business dealings, communications and keep contacts updated.

We process it under Art. 6 para. 1 (f) GDPR, we have a legitimate interest in handling commercial collaboration and updating contacts.

  • Tel.
  • Company
  • Subject
  • Country
Voluntary details:

Processing this is allowed under Art. 6 para. 1 (b) GDPR.

Orders, downloads, bookings on our website

Once you've registered on our website, you can also use chargeable services like booking events or sending event documents. To order these services, as well as the data we gathered when you registered, we also gather and process the order data below.

Mandatory details
  • Billing data (depends on what payment methods we allow and what users select)
  • Time and scope of all chargeable services ordered (shows history of orders made on user account)

To ensure your data is sent securely, we use state of the art encryption procedures, e.g. SSL, via HTTPS.

This processing is allowed under Art. 6 para. 1 (b) GDPR.


We have a newsletter you can subscribe to on our website. We've flagged the data we need to send you it; there is also other data you can send us voluntarily, so we can write to you personally or coordinate content better. We request your consent to processing this data in the course of the subscription procedure citing this data protection statement.

We use the double opt-in method to check that the subscription to the newsletter has actually been made by someone who has an e-mail address. The e-mail address owner cannot subscribe to the newsletter until they have activated it expressly by clicking on the link from the confirmation e-mail. We record conducting the individual phases of the double opt in procedure as evidence.

If you register to subscribe to our newsletter and so agree to us sending it to you, we will only use your data to send you it. You can revoke your consent at any time. You'll find a link you can use to do this in each newsletter. We will note that you have unsubscribed to our newsletter in our database.

Data will be deleted as soon as it is no longer required for the purpose it was gathered for. We save users' e-mail addresses for as long as they subscribe actively to our newsletter.

Processing this is allowed under Art. 6 para. 1 (a) GDPR.

If you register on our portal and provide your e-mail address in connection with this contractual relationship, your e-mail address can subsequently be used by us for direct marketing purposes. In such a case, e.g. a newsletter will be used to send advertising for our own similar goods or services. You can object to this processing at any time without incurring any costs other than the transmission costs according to the basic tariffs. The legal basis is § 7(3) UWG, Art. 6(1)(f) GDPR.

Use of the visitor registration

In context with the visitor registration personal data is gathered. This data will be exclusively used by E-world energy & water for the purpose of statistics, optimisation of business processes, the further development of E-world and for information on this event. If this data is gathered in connection with an invitation code and hence entitles the visitor to free admission, it is passed on to the inviting exhibitor. 

Leadtracking service

In addition, exhibitors will be offered a leadtracking service at the trade fair/congress with which the individual exhibitor will scan the barcode on their badges and thus receive their contact details - similar to a business card. These are: Company name, title, title, first and last name, function, postal address, country, telephone number (s), e-mail address and any other information you have provided about interests and / or your company.

In individual cases, you can decide on the transfer of your data by offering the respective exhibitor your badge for scanning. An unnoticed data collection without your participation does not take place. - In accordance with the international character of the fair (or the congress), exhibitors who are located outside the European Union and thus outside the scope of European data protection laws are also represented. Again, by withdrawing or offering your ticket to scan the disclosure of your data, you may object or agree in individual cases.

In accordance with the applicable data protection laws, you have the right to obtain information from us about your personal data stored by us. You also have the right to correct your personal data, delete or restrict their processing or object to the processing. Likewise, the legislator grants you the right to data portability. In addition, you have the right of appeal to the supervisory authorities.

To process your data, we use various processors who are contractually obliged to process your data only to the extent mentioned above.

Google Analytics

This website uses Google Analytics, a web analysis service of Google Inc, (1600 Amphitheatre Parkway Mountain View, CA 94043, USA; 'Google'). We use it in 'Universal Analytics' mode.

The information this cookie generates about your using this website is usually sent to one of Google's servers in the USA and saved there. If IP anonymisation is activated on this website, however, Google will abbreviate your IP address within Member States of the European Union or in other signatory states to the European Economic Area. Only in exceptional cases will your full IP address be sent to a Google server in the USA and abbreviated there. The IP address your browser sends under Google Analytics will not be combined with other Google data. Under this website operator's instructions, Google will use this information to analyse how you use the website, compile website activity reports and provide other services connected to the website use and Internet use to the website operator.

Sharing content on social networks (Twitter, XING, LinkedIn, Google +1)

You can share the content of our website on social networks via built-in social media interfaces.

That's how we ensure your data is not sent to social network servers automatically as soon as you access our website. When sharing contents of our website, we only send data to the social network which is required to share the content concerned. We do not send any personal data in the process.

There are also other simple links to our Internet presence on each social network. If you follow the link from our website to a social network or log into your social network to share contents from our website, the social network provider concerned will process your data. To find out why a social network provider gathers data and how much data it gathers, how it processes it and uses it and your rights and setting options available to protect your privacy, please see that provider's data protection information.

  • Sales and marketing services providers
  • Hotline services providers
  • Carriers collecting/delivering products

These recipients include service providers and other companies in our group.

Forwarding data to recipients outside the EEA

We also send personal data to recipients who are based outside the EEA in what are known as third states. Before passing it on, we then ensure either that the recipient uses a reasonable level of data protection (e.g. because the European Commission has decided that country is reasonable or has agreed EU standard terms and conditions of contract with the recipient) or that you have consented to its being sent.

To find out more, particularly on the measures we take, you can consult our data protection officer.

Obligation to provide

Insofar as we need your personal data to establish and conduct business dealings and the contractual or statutory obligations this involves, you must provide this data, so we can meet our obligations to perform or legal obligations. Unless you provide your data, we may not be able to provide our services any more or not duly or completely.

Retention times

If we save your personal data, we only do so for a limited period and only for as long as is necessary. In principle, we delete your data when we no longer need it for the purpose for which we gathered it or when the law requires us to delete it for other reasons.

Insofar as the law requires us to retain data for a longer period, particularly to meet commercial and tax law retention periods, we save data for from two to 10 years.

We may also be required to save data for other reasons in law, such as for evidential purposes for as long as the limitation rules applicable last. These periods are generally between two and 30 years.

Your rights in respect of your personal data

The rights you have in respect of your personal data by law are as follows: You can apply to our data protection officer, even if you'd like to know more about what these rights mean individually. As the legal details are highly complex, we will give you the main details of your rights below. Please let us know in what form you would like the information. If you don't say in what form you'd like it, we will usually answer your queries in the same form as that in which you made them. You will hear back from us within a month. If enquiries are obviously unfounded or excessive, we may demand reasonable payment or refuse to answer them.

Accessing your data, Art. 15 GDPR

You have the right to ask whether we process your personal data or not. If we process your personal data, we will tell you what specific data it is and give you further information.

Correcting your data, Art. 16 GDPR

You have the right to demand that we correct your data insofar as it is incorrect, inaccurate and/or incomplete; the right to correct it also includes the right to complete it by making additional statements or communications.

Deleting your data, Art. 17 GDPR

You have the right to demand that we delete your personal data if we have no further reason to keep it.

Restricting our processing your data. Art. 18 GDPR

You have the right to have processing your personal data restricted to a given extent in given cases.

Data portability, Art. 20 GDPR

You have the right in some cases to demand that we surrender the data concerning you in a commonly used electronic machine-readable form.

The right to data portability includes the right to have data transmitted to another controller; we will therefore transfer data directly to a controller you nominate or will nominate on demand, insofar as technically possible. The right to transmit data applies only to data you provided and assumes that it is processed based on consent or to perform a contract and is carried out using automated procedures.

Objecting to our processing your data, Art. 21 GDPR

Where personal data is processed to perform tasks in the public interest (Art. 6 para. 1 (e) GDPR) or exercise legitimate interests (Art. 6 para 1 (f) GDPR), you can object to personal data concerning you being processed with effect for the future at any time if there is no reason to continue processing it.

(Please note, you do not have the right to object in law if data is processed based on consent. But as you have a right to revoke your consent with effect for the future at any time if data is processed with your consent, you can achieve an effect comparable with objecting by revoking it.)

Revoking consent

If you consented to us processing your personal data, you can revoke that consent at any time with effect for the future without giving any reasons. Please contact the contact to whom you gave your consent or directly to our data protection officer.


You have the right to complain to the competent supervisory authority about your personal data being processed, Art. 77 GDPR.
