Yes we use data. Most of this data is automatically collected data from our voltage optimization devices. But there are exceptions. That’s why data privacy is of a particularly high priority at Energy Labs. Read about what we do and what you can do about it.

Privacy Statement

The use of the Internet pages of the Energy Labs GmbH is possible without any indication of personal data; however, if a data subject wants to use special enterprise services via our website, processing of personal data could become necessary. If the processing of personal data is necessary and there is no statutory basis for such processing, we generally obtain consent from the data subject.

The processing of personal data, such as the name, address, e-mail address, or telephone number of a data subject shall always be in line with the General Data Protection Regulation (GDPR), and in accordance with the country-specific data protection regulations applicable to the Energy Labs GmbH. By means of this data protection declaration, our enterprise would like to inform the general public of the nature, scope, and purpose of the personal data we collect, use and process. Furthermore, data subjects are informed, by means of this data protection declaration, of the rights to which they are entitled.

As the controller, the Energy Labs GmbH has implemented numerous technical and organizational measures to ensure the most complete protection of personal data processed through this website. However, Internet-based data transmissions may in principle have security gaps, so absolute protection may not be guaranteed. For this reason, every data subject is free to transfer personal data to us via alternative means, e.g. by telephone.
The controller within the meaning of data protection laws, with particular reference to the EU General Data Protection Regulation (GDPR), is:


Energy Labs GmbH
Mehringdamm 34
