We take the protection of your personal data extremely seriously and strictly adhere to the provisions of the General Data Protection Regulation (GDPR), as well as the national data protection regulations applicable to us. The following Privacy Policy provides an overview of the nature, extent and purpose of data processing in plain language.

We employ technical and organisational measures to protect our website and the data administered against intentional or accidental manipulation, loss, destruction and alteration, as well as against unauthorised third-party access. Existing security measures are enhanced on an ongoing basis to keep pace with technological developments

This Privacy Policy applies to data processing carried out by Die Mehrwertbauer GmbH, Tucholskystrasse 26, 10117 Berlin, Germany, email:, tel. +49 (0)30 2789 0417.

2. Personal data
Pursuant to Article 4 (1) of the GDPR, personal data means any information relating to an identified or identifiable natural person. An identifiable natural person is one who can be identified, directly or indirectly, in particular by reference to an identifier such as a name, an identification number, location data, an online identifier or to one or more factors specific to the physical, physiological, genetic, mental, economic, cultural or social identity of that natural person. Personal data includes, for example, information such as names, addresses, telephone numbers and email addresses.

3. Collection and storage of data when you visit our website
When you visit our website, data transmitted by your browser will be collected by the Web server for the purpose of data transfer and, in some cases, will be stored in the form of log files. This includes information on the operating system used, the browser used, the browser version, the country from which the access request was made, the provider with which the access request was made (with pseudonymised IP address), the time of the access request, the ‘referrer’ (site visited immediately before the request), the time of the server request, the amount of data transferred and any files downloaded (only visible as a summary). We are unable to identify a specific person using this data, as the ID address is pseudonymised. This data will not be associated with data from any other source. Data is collected and stored to ensure a seamless connection and a user-friendly website experience, to analyse system security/stability and for other administrative reasons. The legal basis for data processing is Article 6 (1f) of the GDPR.

4. Data transfer abroad
Insofar as we store or process personal data, this will be done solely in Germany. In respect of the embedding of the third-party content outlined below (social media and Google Maps), data is regularly transferred to the third-party providers concerned. Data may be transferred abroad in the process. For more details, please refer to the relevant third-party content.

5. Social Media
Social media content is embedded in accordance with Article 6 (1f) of the GDPR and on the basis of the legitimate interests of the social media provider in the display of personalised advertising in order to inform other users of the social networks of your activities on our website and to configure the service in line with needs.

6. YouTube
Our website contains plug-ins of the video site YouTube, which is operated by Google LLC, represented by Google Inc., 600 Amphitheatre Parkway, Mountain View, CA 94043, USA. Google LLC is Privacy Shield-certified.

As soon as you visit a page fitted with a YouTube plug-in, a connection will be established with YouTube servers. In the process, the YouTube server will be notified of which specific page on our website you have visited. In the event that you are signed in to your YouTube account, YouTube is able to associate your surfing habits with your personal profile. You can prevent this information from being associated by signing out of your account before visiting the pages concerned. For more information on the collection and use of your data by YouTube, please refer to the privacy policy and other policies on YouTube.

When you use YouTube content, data may be transferred to Google. Google, which is headquartered in the USA, is certified in accordance with the ‘Privacy Shield’ data protection framework, which guarantees compliance with the data protection standards applicable in the EU.

7. Google Maps
We have incorporated map material from the Google Maps service from Google LLC, represented by Google Inc., 600 Amphitheatre Parkway, Mountain View, CA 94043, USA, in our website via an API.

The legal basis for this data processing is Article 6 (1b) of the GDPR, as the IP address is required to provide you with map content. In respect of the processing of this data, our partnership with Google is based on a ‘joint controller’ agreement on the basis of Article 26 of the GDPR, which can be accessed here. For more information on data processing by Google, please refer to the Google Privacy Policy under Google Terms and Policies.

When you use Google Maps content, data will be transferred to Google. Google, which is headquartered in the USA, is certified in accordance with the ‘Privacy Shield’ data protection framework, which guarantees compliance with the data protection standards applicable in the EU.

8. Sharing of data with third parties
We will only share your data with third parties if you have given your express consent for this in accordance with Article 6 (1a) of the GDPR, if it is necessary to do so for the purpose of establishing, exercising or defending legal claims pursuant to Article 6 (1f) of the GDPR and there is no reason to assume that you have an overriding interest in the data not being shared, in the event that the data needs to be shared to comply with a legal obligation pursuant to Article 6 (1c) of the GDPR or insofar as it is necessary to share the data for the performance of a contract with you pursuant to Article 6 (1b) of the GDPR. In the last of these instances, your personal data will only be shared with third parties who are service providers involved in the performance of the contract, e.g. the logistics company tasked with delivery and the financial institution tasked with payment-related matters. In all instances in which your personal data is shared with third parties, however, the extent of the data transferred will be kept to the necessary minimum.


As a data subject (person whose personal data is processed), the applicable legislation gives you extensive rights. These are as follows:

Right to object
Insofar as your personal data is processed on the basis of legitimate interests pursuant to Article 6 (1f) of the GDPR, you have the right, pursuant to Article 21 of the GDPR, to object to the processing of your personal data on grounds relating to your particular situation or if you object to direct marketing. In the latter instance, you have a general right to object, which we will respect without you having to state a particular situation. If you wish to exercise your right to withdraw consent or object, an email sent to the aforementioned email address will suffice.

Right of access (Article 15 of the GDPR)
You have the right to information about your personal data processed by us, the purposes for which it is being processed, the categories of data concerned, the recipients or categories of recipient to whom your data is disclosed, the envisaged storage period or, if not possible, the criteria used to determine this period, your rights as a data subject, the source of your data in the event that it has not been collected by us and your right to information about the safeguards in place pursuant to Article 46 of the GDPR if personal data is transferred to third countries.

Right to rectification (Article 16 of the GDPR)
You have the right to immediate rectification and/or completion of the personal data we hold about you.

Right to erasure (Article 17 of the GDPR)
You have the right to have your personal data erased in the event that the requirements stipulated in Article 17 (1) of the GDPR are met. This right may be restricted if processing is required for the purpose of exercising the right of freedom of expression and information, for compliance with a legal obligation, for reasons of public interest or for the establishment, exercise or defence of legal claims.

Right to restriction of processing (Article 18 of the GDPR)
You have the right to restrict processing of your personal data while the accuracy of your personal data is being verified in cases where you have contested its accuracy, where data processing is unlawful but you oppose the erasure of the data and request restriction of its processing instead, where you require the data for the establishment, exercise or defence of legal claims after we no longer require it for the purposes of the processing or where you have objected to processing for reasons of your particular situation pending verification of whether we have overriding legitimate interests.

Right to notification (Article 19 of the GDPR)
If you have exercised your right to rectification, erasure or restriction of processing to us, we are obliged to inform all recipients to whom we have disclosed your personal data of this rectification or erasure of the data, or the restriction of its processing, unless this proves to be impossible or involves disproportionate effort. You have the right to be informed of these recipients..

Right to data portability (Article 20 of the GDPR)
You have the right to receive – in a structured, commonly used and machine-readable format – the personal data that you have provided to us or to have this data transmitted to another controller insofar as technically feasible.

Right to withdraw consent granted (Article 7 [3] of the GDPR)
You have the right to withdraw your consent with future effect at any time. In the event of consent being withdrawn, we will erase the data concerned without undue delay insofar as there is no legal basis for continued processing without your consent. The withdrawal of consent shall not affect the lawfulness of the processing based on consent before its withdrawal.

Right to lodge a complaint (Article 77 of the GDPR)

We kindly ask you to notify us if you suspect a breach of applicable data protection legislation. We will review your notification as soon as possible and take any necessary action. You also have the option of lodging a complaint with the responsible supervisory authority.
