CO2 Neutrale Software – Data protection

Version 1.1 | dec. 2019

At CO2 Neutrale Software, accessible from, one of our main priorities is the privacy of our visitors. This Privacy Policy document contains types of information that is collected and recorded by CO2 Neutrale Software and how we use it.

Legal duty

The company CO2 Neutrale Software GMBH not only find the confidentiality of data important for moral considerations; processing personal data also happens in accordance with privacy laws. As a processor of personal data of customers and business relationships, we must comply with the rules laid down in the General Data Protection Regulation (GDPR). The GDPR has been valid for the whole European Union (EU) since 25 May 2018.

Foundations for the processing of your data

CO2 Neutrale Software process data because this is necessary for the performance of the agreement. For example, because the processing is necessary to deliver our products and services. It may also be that we process data because we ourselves have a legitimate interest in this. As is the case with marketing. Personal data can also be processed on the basis of consent. For example, we ask for permission before we place cookies or when processing the energy data via our CO2 Neutrale Software program.

Information about Digital Energy and Quarter Management – CO2 NeutraleSoftware

The CO2-free energy supply of residential districts will be standard in Europe in the foreseeable future. New digital technologies are to be implemented. However modern energy management systems require large amounts of personal data. We have developed our own data protection technology for this purpose. This energy management system only works if there is sufficient data to control it. If there is more data available, the software will be smarter and more efficient, meaning more energy can be stored and used. Ultimately, the software should not only control an effective use of energy, but also calculate the energy costs for each household with kilowatt-hourly accuracy.

The energy management system evaluates very precisely personal data, from which, for example, attendance times and usage habits can be derived. For example: when does the computer, TV, washing machine or other devices run, when is someone cooking, etc. Even deducting that would be possible.

The European General Data Protection Regulation (GDPR) requires data subjects to always give their consent to data processing. This also applies to the residents in urban districts. They must also agree to the use of personal data in advance. However, consent is not enough. The GDPR also requires that data be anonymized and used only for the specified purpose, while complying with the principle of data minimization. The purpose limitation can be established relatively easily: “If, for example, we only need the power consumption data to plan a quarter storage in a resolution of 15 minutes, then we store it only at these intervals and not at five-minute intervals because that would be much more critical to privacy,” says evohaus Managing Director Heinz Hanen.

The Karlsruhe Institute of Technology (KIT) has now developed a new encryption technology for the energy management system in a research project to comply with the legal requirements and to effectively protect data of the inhabitants. Differential Privacy is what the scientists call the technique used to prevent the return to the original data. With this method, the data is not only anonymized but changed before the statistical analysis. “It is an elaborate procedure and the costs are also relatively high, but the principle of differential privacy offers by far the best protection of personal data,” says KIT-expert Schäler.
