"Pseudonymisation" means the processing of personal data in such a way that the personal data can no longer be attributed to a specific data subject without additional information, provided that this additional information is kept separately and is subject to technical and organisational measures ensuring that the personal data are not attributed to an identified or an identifiable natural person.

"Profiling" means any form of automated processing of personal data consisting of the use of personal data to evaluate certain personal aspects relating to a natural person, in particular to analyse or predict aspects concerning that natural person’s performance at work, economic situation, health, personal preferences, interests, reliability, behaviour, location, or movements.

"Data controller" refers to the natural or legal person, public authority, agency, or any other body that alone or jointly with others determines the purposes and means of the processing of personal data.

Security measures

In accordance with legal requirements, we take appropriate technical and organisational measures to ensure a level of protection appropriate to the risk, taking into account current technology, implementation costs, the nature, scope, context and purposes of processing, and the varying likelihood and severity of the risk to the rights and freedoms of natural persons.

The measures include, in particular, ensuring the confidentiality, integrity and availability of data by controlling physical access to the data, as well as the access, input, transmission, security of availability and its separation. Furthermore, we have established procedures that guarantee the exercise of data subjects' rights, deletion of data, and reaction to data risks. In addition, we take the protection of personal data into account as early as the development or selection of hardware, software and procedures, in accordance with the principle of data protection through technology design and data protection-friendly defaults.

Collaboration with processors, mutually responsible persons and third parties

If, in the context of our processing, we disclose data to other persons and companies (processors, mutually responsible persons or third parties), transmit it to them or otherwise grant access to the data, this will only be done on the basis of a legal permission (e.g. if the data has been transmitted to third parties, such as payment service providers, to fulfil the contract), users have consented to a legal obligation to do so or on the basis of our legitimate interests (e.g. the use of agents, web hosters, etc.).

Insofar as we disclose data to other companies in our group, convey it or otherwise grant access to it, this is done in particular for administrative purposes as a legitimate interest and, moreover, on a basis that complies with the legal requirements.

Transfer of data, login administration and transfers to third countries

The processing of the data generated in the app is carried out in Germany (Server: Server4You), as well as German and Dutch partners.

If we process data in a third country (i.e. outside the European Union (EU), the European Economic Area (EEA) or the Swiss Confederation) or in the context of the use of third party services or disclosure, or transmission of data to other persons or companies, this will only happen if it is to fulfil our (pre)contractual obligations, on the basis of your consent, on the basis of a legal obligation or on the basis of our legitimate interests. Except as expressly provided or required by law, we process or disclose the data only in third countries with a recognised level of privacy, including those certified under the Privacy Shield, or on the basis of specific warranties, such as contractual obligations under so-called standard safeguards of the EU Commission, the existence of certifications or binding internal data protection regulations (articles 44 to 49 GDPR, information page of the European Commission).).

Registration function

Users can create a user account. Users will be informed of the mandatory information required during registration and this information will be processed on the basis of Art. 6 para. 1 (b) GDPR for the purpose of providing the user account. The processed data includes, in particular, the login information (e-mail address). The data entered during registration will be used to reset the password.

We use the social login feature of the providers Facebook, Twitter and Google. Accounts created in this way fall under local data protection rules.

Backup of content data of the user-created data does not take place outside of the user account. If an account is deleted, all contents will be irretrievably deleted.

We store the IP address and the time of the respective user's activity as part of the use of our registration and login functions, as well as the use of the user account. This data is stored on the basis of our legitimate interests, and to protect the user against misuse and other unauthorised use. A passing on of this data to third parties does not take place in principle, unless it is necessary for the pursuit of our claims or there is a legal obligation in accordance with Art. 6 para. 1 (c) of the GDPR. IP addresses are anonymised or deleted after 7 days at the latest.

Comments and posts

If users leave comments or other posts, their IP addresses can be stored for 7 days on the basis of our legitimate interests within the meaning of Art. 6 para. 1 lit. f. GDPR. This takes place for our security, in case someone leaves illegal contents in comments and posts (abuse, forbidden political propaganda, etc.). In this case, we ourselves could be prosecuted for the comment or post and are therefore interested in the identity of the author. 

Furthermore, we reserve the right, on the basis of our legitimate interests pursuant to art. 6 para. 1 lit. f. GDPR, to process user information for the purpose of spam detection.

On the same legal basis, we reserve the right, in the case of surveys, to store the IP addresses of users for the duration of the survey and to use cookies to avoid multiple votes.

Any information provided in the comments and contributions of the person, any contact and website information as well as the content, are stored by us indefinitely unless the user requests the information to be deleted.

Hosting and email delivery

The hosting services we use serve from the provider Time4VPS to provide the following services: infrastructure and platform services, computing capacity, storage space and database services, email delivery, security services and technical maintenance services that we use for the purpose of operating this online offering.

Hereby, we or our hosting provider process inventory data, contact data, content data, contract data, usage data, meta data and communication data of customers, potential customers and visitors to this online offer on the basis of our legitimate interests in an efficient and secure provision of this online offer according to art. 6 para. 1 lit. f GDPR in conjunction with art. 28 GDPR (fulfilment of order processing agreement).

Collection of access data and log files

We, or our hosting provider, collect data on the basis of our legitimate interests within the meaning of art. 6 para. 1 lit. f. GDPR regarding each access to the server on which this service is located (known as server log files). Access data includes the name of the requested website, file, date and time of access, amount of data transferred, report whether the site was successfully retrieved, browser type and version, the user's operating system, the referrer URL (the site visited before coming to our site), the user's IP address, and the requesting internet service provider.

Log file information is stored for a maximum of seven days for security reasons (e.g. to investigate misuse or fraud) and then deleted. Data which must be retained as potential evidence is not deleted until the relevant incident has been ultimately clarified.
