Google stores the collected information on its servers in the United States. Google also provides this information to advertisers to provide insight into the effectiveness of their campaigns. Google may also provide this information to third parties if Google is legally obliged to do so, or to third parties who process the information on behalf of Google. We have no influence on this. We have not allowed Google to use the obtained analytics information for other Google services. Read Google's privacy policy for more information, as well as the specific privacy policy of Google Analytics.


We use cookies to make our website function properly and to analyse our website traffic. We also share information about your use of our site with our analytics partner who may combine it with other information that you’ve provided to them or that they’ve collected from your use of their services.

Cookies and other similar techniques, such as scripts, are small files that can be placed from our domains on the user's devices. Based on cookies, you can be recognized on a subsequent visit and information can be collected about the use of the websites. There are different types of cookies. In some cases, cookies are automatically deleted when you close your browser. In other cases, these cookies are retained for a longer period of time and can also be read out for subsequent use of the services.

Metrological only uses functional cookies. These are cookies that are necessary for the proper functioning of our website. Without these cookies, certain parts of the website cannot be used or may not function properly. For example, Metrological uses cookies to log in and to remember settings and preferences.


We may disclose Personal Data to the following categories of recipients:

  • Third-party service providers. We use service providers, which are not part of the Metrological corporate family, to support us in providing our services and to operate our business. These service providers provide support services such as marketing services, companies providing tools for creating Metrological digital certificates, online surveys and hosting services. All service providers are contractually required to continue to adequately safeguard your Personal Data. For example, we use MailChimp to manage our e-mail communications. Their privacy policy is available at
  • Subsidiaries and affiliates. We may share Personal Data to our subsidiaries and affiliates (including those located outside the European Economic Area and Switzerland) as necessary to support provision of our services and to operate our business.
  • Competent authorities. We disclose Personal Data to law enforcement insofar as it is required by law or is strictly necessary for the prevention, detection or prosecution of criminal acts and fraud or if we are otherwise legally obliged to do so.


We may retain your Personal Data for a period of time consistent with the original purpose of collection. We determine the appropriate retention period for Personal Data on the basis of the amount, nature and sensitivity of your Personal Data processed, the potential risk of harm from unauthorized use or disclosure of your Personal Data and whether we can achieve the purposes of the processing through other means, as well as on the basis of applicable legal requirements (such as applicable statutes of limitation).

In some cases the storage of your Personal Data is linked to the term of the applicable concluded agreement. This is the case for the dashboard. After termination or expiration of this agreement, Metrological will use best efforts to make sure that the data will be deleted immediately.

We retain data in relation to customer satisfaction surveys conducted for five years, so we can compare the results of the survey with previous years. We aim to aggregate these data to a level that we cannot, or no longer, identify you. However, if there are a relatively low number of participants in the survey or based on the uniqueness of the answers given by you, it cannot be ruled out that we may be able to identify you up to five years after the survey has been conducted.

We retain data in the Metrological Certified Lightning Developers’ database for as long as your Metrological Lightning Developer certification is still valid.

After expiry of the applicable retention periods, your Personal Data will be deleted. If there is any data that we are unable, for technical reasons, to delete entirely from our systems, we will put in place appropriate measures to prevent any further use of such data.

For further information on applicable data retention periods, please contact us by using the information in the “Contact Us” section, below.


The processing of Personal Data as described in this Privacy Statement may include overseas transfers of Personal Data to countries whose data protection laws are not as comprehensive as those of the countries within the European Union. Where required by European law, we shall only transfer Personal Data to recipients offering an adequate level of data protection. In these situations, as may be required, we make contractual arrangements to ensure that your Personal Data is still protected in line with European standards.
