Acquisition and storage of personal data as well as forms and purposes of data usage

When visiting the website:
When visiting our website, the browser used on your device automatically sends information to our website server. This information is stored temporarily in a so-called logfile. The following information is gathered without any action on your part and is stored until the next automatic deletion:

•  IP address of the inquiring computer;
•  date and time of access;
•  name and URL of the accessed file;
•  website from which the connection was made (referrer URL), and
•  browser used and potentially the operating system of your computer as well as the name of your access provider.

This information is used on our part for the following purposes:

•  guarantee of a seamless connection to our website;
•  guarantee of a comfortable use of our website;
•  assessment of system security and stability, and 
•  other administrative purposes.

The legal basis for our data processing is Art. 6 Abs. 1 S. 1 lit. f DSGVO. Our legitimate interest follows from the purposes for the acquisition of data outlined above. Under no circumstances do we use the acquired data to make inferences related to your person.  

Disclosure of data

No disclosure of your personal data to third parties will occur other than for the following purposes. We only disclose your personal data to third parties in cases where: 

•  you expressly agreed to the disclosure of your data according to Art. 6 Abs. 1 S. 1 lit. a DSGVO;
•  a disclosure according to Art. 6 Abs. 1 S. 1 lit. f DSGVO is necessary for the enforcement, exercise, or defense of legal claims and there is no reason to assume that you have a prevailing interest in the nondisclosure of your data that is worthy of protection;
•  in cases when a legal obligation of disclosure arises according to Art. 6 Abs. 1 S. 1 lit. c DSGVO;
•  a disclosure is legally permissible and necessary for the implementation of contractual agreements with you according to Art. 6 Abs. 1 S. 1 lit. b DSGVO.

Transmission to third-party countries

Insofar as we process data in a third-party country (meaning outside of the European Union [EU] or the European Economic Area [EEA]) or that this occurs in the framework of the use of the services of third parties or in the disclosure or transfer of data to third parties, this only occurs in cases that serve the fulfillment of our (pre-)contractual obligations, on the basis of your consent, due to a legal obligation, or on the basis of our legitimate interests. In accordance with legal or contractual stipulations, we only allow data to be processed in a third-party country when the special conditions of Art. 44 ff. DSGVO are fulfilled. This means that processing occurs for example on the basis of special guarantees such as the officially recognized ascertainment of a level of data protection meeting the standards of the EU (e.g. in the USA through the »Privacy Shield«) or through compliance with officially recognized special contractual obligations (so-called standard contractual clauses).

Performance of our services according to our statutes and business

We process the data of our members, supporters, interested parties, and other persons according to Art. 6 Abs. 1 lit. b. DSGVO, insofar as we are offering you contractual services or are active in the context of existing business relationships, for example in relation to members, or when we are ourselves the recipients of services and contributions. We moreover process data of persons according to Art. 6 Abs. 1 lit. f. DSGVO on the basis of our legitimate interests, for example in relation to our administrative tasks or public outreach. The data processed in these cases and the manner, scope, purpose, and necessity of their processing are determined by the underlying contractual relationship. This includes basic inventory and reference data of persons (e.g. name, address, etc.) as well as contact details (e.g. email address, phone number, etc.), contractual data (e.g. services used, content and information shared, or names of contacts), and payment details in cases where we offer fee-based services or products (e.g. bank details, payment history, etc.). We delete data that is no longer necessary for the fulfillment of our purposes according to our statutes and business. This is determined according to the respective tasks and contractual relationship. In the case of business processing, we keep data as long as necessary for the completion of the business and as long as any guarantees or liabilities remain relevant. Otherwise, the legal responsibilities concerning data storage apply. 

Administration, financial accounting, office management, and contact administration

We process data in the framework of the administrative duties and organization of our company, of financial accounting, and of the fulfillment of legal responsibilities, for example archiving. We here process the same data as we do in the rendering of our contractual services. The basis for this processing is Art. 6 Abs. 1 lit. c. DSGVO, Art. 6 Abs. 1 lit. f. DSGVO. The concerned parties include interested persons, partners, and website visitors. Our purpose and interest in processing concerns administration, financial accounting, office management, and the archiving of data, in other words tasks that serve the maintenance of our activities, the perception of our activities, and the rendering of our services. The deletion of data relating to contractual services and contractual communication corresponds to the tasks cited in relation to these processing activities. In this context, we disclose or transfer data to the financial administration, financial consultants such as tax consultants or auditors, as well as further financial offices and payment service providers. We moreover store data relating to suppliers, event organizers, and other business partners on the basis of our business interests, for example for the purpose of taking up contact at a later date. We generally store such predominantly company-related data permanently. 

Data deletion

The data processed by us is either deleted according to the provisions of Art. 17 und 18 DSGVO or its processing is limited. Unless explicitly stated otherwise in this data protections statement, the data stored by us is deleted as soon as it is no longer required for its original purpose and there are no legal storage requirements barring its deletion. Insofar as data is not deleted because it is necessary for other legally permissible purposes, its processing is limited. This means that this data is locked and not used for other purposes. This concerns for example data that needs to be stored for reasons relating to business or tax law. According to German legal provisions, data storage occurs for 6 years according to § 257 Abs. 1 HGB (account books, inventories, opening balance sheets, annual financial statements, business letters, booking receipts, etc.) and for 10 years according to § 147 Abs. 1 AO (books, records, management reports, booking receipts, business letters, documents relevant to taxation, etc.).

Online presence in social media

We maintain an online presence within social media and platforms in order to communicate with interested persons, and users active in these domains and to inform them within these domains about our activities. The viewing of the respective network or platform is subject to the terms and conditions and data processing guidelines of the respective provider. Where nothing further is stipulated in the framework of our data protection statements, we process user data insofar as these users communicate with us within these social networks and platforms, for example writing contributions to our online presence or sending us messages. 

Use of Facebook Social Plugins

On the basis of our legitimate interests (meaning our interest in the analysis, optimization, and economic operation of our online services according to Art. 6 Abs. 1 lit. f. DSGVO), we use social plugins (»plugins«) of the social network, operated by Facebook Ireland Ltd., 4 Grand Canal Square, Grand Canal Harbour, Dublin 2, Ireland (»Facebook«).

When a user makes use of a function of our online services containing such a plugin, the user’s device establishes a direct connection to the Facebook servers. The content of the plugin is relayed directly to the user’s device by Facebook and the user is connected to the online service by Facebook. From the data processed thereby, user profiles can be created for the users. We therefore have no influence on the scope of data that Facebook collects with the aid of this plugin and the user is therefore only informed according to our level of knowledge. Through connecting to the plugin, Facebook receives the information that a user has accessed a particular page of the online service. If the user is logged in to Facebook, Facebook can connect the visit to the respective Facebook account. When users interact with plugins, for example using the like button or writing a comment, this information is transmitted directly from their device to Facebook and is saved there. If the user is not a member of Facebook, it is still possible for Facebook to acquire and store their IP address. According to Facebook, only anonymized IP addresses are stored in Germany. The purpose and scope of data acquisition and the further processing and use of data by Facebook as well as the appertaining rights and settings options relating to the protection of the user’s privacy can be viewed under the data protection stipulations of Facebook under

If the user is a member of Facebook and does not wish Facebook to collect their data via this online service and to connect it with the user data stored by Facebook, the user needs to log out of Facebook before accessing our online services and to delete their cookies. Further settings and objections to the use of data for marketing purposes are available within the Facebook profile settings under

This allows Instagram to associate your visit to this website with your user account. We would like to point out that we, as the provider of the pages, have no knowledge of the content of the transmitted data or its use by Instagram.

Insofar as personal data is collected on our website with the help of the tool described here and forwarded to Facebook or Instagram, we and Meta Platforms Ireland Limited, 4 Grand Canal Square, Grand Canal Harbour, Dublin 2, Ireland are jointly responsible for this data processing (Art. 26 DSGVO). The joint responsibility is limited exclusively to the collection of the data and its forwarding to Facebook or Instagram. The processing by Facebook or Instagram that takes place after the forwarding is not part of the joint responsibility.

Our joint obligations have been set out in a joint processing agreement. The text of the agreement can be found at:

Matomo uses technologies that allow for the recognition of users across websites for the purposes of analyzing usage (e.g. cookies and device fingerprinting). The information collected by Matomo about the usage of this website is saved on our server. The IP addresses are anonymized before saving.

With the help of Matomo, we are able to collect and analyze data concerning the usage of our website by visitors. This allows us to ascertain among other things when the pages are accessed, which pages are accessed, and from which region. We moreover collect various log data (e.g. IP addresses, referrers, as well as browsers and operating systems used), which allows us to measure whether our website visitors are able to perform particular actions (e.g. clicks etc.).

The use of this analytical tool occurs on the basis of Art. 6 Abs. 1 lit. f DSGVO. The website provider has a legitimate interest in the anonymous analysis of user behaviors in order to optimize both the online offer and the advertising. In cases where consent is requested (e.g. consent to save cookies), the usage occurs exclusively on the basis of Art. 6 Abs. 1 lit. a DSGVO. Consent can be revoked at any time.

We anonymize IP addresses in our analyses using Matomo, which involves the given IP address being abbreviated before the analysis so that the user can no longer be clearly identified.
