Privacy Policy

1. Introduction
In the following, we provide information about the collection of personal data when using:
our website www.buildersnetwork.co
our profiles in social media.
Personal data is any data that can be related to a specific natural person,such as their name or IP address.
1.1. Contact details
The controller within the meaning of Art. 4 (7) EU General Data Protection Regulation (GDPR) is
BuildersNetwork UG (haftungsbeschränkt), Lohmühlenstraße 65, 12435 Berlin, Germany,
We are legally represented by Jacopo Luperi.
Our data protection officer is
heyData GmbH, Gormannstr. 14, 10119 Berlin,
Web www.heydata.eu
E-mail info@heydata.de
1.2. Scope of data processing, processing purposes and legal bases
We detail the scope of data processing, processing purposes and legal bases below. In principle, the following come into consideration as the legal basis for data processing:
- Art. 6 para. 1 s. 1 it. a GDPR serves as our legal basis for processing operations for which we obtain consent.
- Art. 6 para. 1 s. 1 lit. b GDPR is the legal basis insofar as the processing of personal data is necessary for the performance of a contract, e.g. if a site visitor purchases a product from us or we perform a service for him. This legal basis also applies to processing that is necessary for pre-contractual measures, such as in the case of inquiries about our products or services.
- Art. 6 para. 1 s. 1 lit. c GDPR applies if we fulfill a legal obligation by processing personal data, as may be the case, for example, in tax law.
- Art. 6 para. 1 s. 1 lit. f GDPR serves as the legal basis when we can rely on legitimate interests to process personal data, e.g. for cookies that are necessary for the technical operation of our Website
1.3. Data processing outside the EEA
Insofar as we transfer data to service providers or other third parties outside the EEA, the security of the data during the transfer is guaranteed by adequacy decisions of the EU Commission, insofar as they exist (e.g. for Canada and Israel) (Art. 45 para. 3 GDPR).
If no adequacy decision exists (e.g. for the USA), the legal basis for the data transfer are usually, i.e. unless we indicate otherwise, standard contractual clauses. These are a set of rules adopted by the EU Commission and are part of the contract with the respective third party. According to Art. 46 (2) lit. b GDPR, they ensure the security of the data transfer. Many of the providers have given contractual guarantees that go beyond the standard contractual clauses to protect the data.These include, for example, guarantees regarding the encryption of data or regarding an obligation on the part of the third party to notify data subjects if law enforcement agencies wish to access the respective data.The transfer of data to third parties in the United Kingdom of Great Britain and Northern Ireland is currently based on the transitional arrangement in the trade and cooperation agreement between the European Union and the United Kingdom.1.4. Storage duration
Unless expressly stated in this privacy policy, the data stored by us will be deleted as soon as they are no longer required for their intended purpose and no legal obligations to retain data conflict with the deletion. If the data are not deleted because they are required for other and legally permissible purposes, their processing is restricted, i.e. the data are blocked and not processed for other purposes. This applies, for example, to data that must be retained for commercial or tax law reasons.
1.5. Rights of data subjects
Data subjects have the following rights against us with regard to their personal data:
- Right of access,
- Right to correction or deletion,
- Right to limit processing,
- Right to object to the processing,
- Right to data transferability,
- Right to revoke a given consent at any time.
Data subjects also have the right to complain to a data protection supervisory authority about the processing of their personal data.1.6. Obligation to provide data
Within the scope of the business or other relationship, customers, prospective customers or third parties need to provide us with personal data that is necessary for the establishment, execution and termination of a business or other relationship or that we are legally obliged to collect. Without this data, we will generally have to refuse to conclude the contract or to provide a service or will no longer be able to perform an existing contract or other relationship. Mandatory data are marked as such.
1.7. No automatic decision making in individual cases
As a matter of principle, we do not use a fully automated decision-making process in accordance with article 22 GDPR to establish and implement the business or other relationship. Should we use these procedures in individual cases, we will inform of this separately if this is required by law.
1.8. Making contact
When contacting us, e.g. by e-mail or telephone, the data provided to us (e.g. names and e-mail addresses) will be stored by us in order to answer questions. The legal basis for the processing is our legitimate interest (Art. 6 para. 1 s. 1 lit. f GDPR) to answer inquiries directed to us.
We delete the data accruing in this context after the storage is no longer necessary or restrict the processing if there are legal retention obligations.

Data processing on social media platforms
We are represented in social media networks in order to present our company and our services there. The operators of these networks regularly process their users’s data for advertising purposes.
Among other things, they create user profiles from their online behavior, which are used, for example, to show advertising on the pages of the networks and elsewhere on the Internet that corresponds to the interests of the users. To this end, the operators of the networks store information on user behavior in cookies on the users’ computers. Furthermore, it cannot be ruled out that the operators merge this information with other data.
Users can obtain further information and instructions on how to object to processing by the site operators in the data protection declarations of the respective operators listed below. It is also possible that the operators or their servers are located in non-EU countries, so that they process data there. This may result in risks for users, e.g. because it is more difficult to enforce their rights or because government agencies access the data. If users of the networks contact us via our company profiles, we process the data provided to us in order to respond to the inquiries. This is our legitimate interest, so that the legal basis is Art. 6 para. 1 s. 1 lit. f GDPR.
