We use the web analytics tool Pirsch Analytics from Emvi Software GmbH (Germany) to evaluate user behavior on our website. Pirsch Analytics works entirely without cookies and collects data as sparingly as possible. No user profiles are created across multiple websites.

Functionality and type of data collected

For analysis purposes, Pirsch generates a pseudonymized visitor ID with each page view. This ID is formed from the following information:

• the IP address (used as part of the calculation, but not stored),
• the user agent (browser type and operating system),
• the respective date,
• a random string that only applies to our domain (“salt”).

The combination of these values is encrypted using a hash function so that no conclusions can be drawn about individuals. The visitor ID is valid for a maximum of 24 hours and is then automatically renewed. Pirsch Analytics only stores the following information, which is anonymized or pseudonymized in accordance with the state of the art:

• Path of the page visited (not the entire URL),
• Approximate location (country, city), language settings,
• Browser type, operating system, and screen resolution,
• Timestamp of the visit,
• Any defined events (e.g., clicks, downloads, form completions).

The IP address is never stored or logged in plain text.

Although no direct conclusions can be drawn about your identity and no data such as your name or email address are processed, according to current case law (ECJ, BGH), pseudonymous or hashed data such as temporary visitor IDs are also considered personal data, as a personal reference cannot be completely ruled out, at least in theory.

The data is processed exclusively for anonymous statistical analysis in order to improve our offering and the user-friendliness of the website. The legal basis for processing is our legitimate interest pursuant to Art. 6 (1) lit. f GDPR in conducting a data-minimized reach analysis.

All analysis data is stored exclusively in encrypted form on servers in Germany (at Hetzner Online GmbH). No data is transferred to third countries. A contract for order processing in accordance with Art. 28 GDPR has been concluded with Emvi Software GmbH.

Details on data protection at Pirsch Analytics can be found here in the provider's privacy policy.

When you use this website, various personal data is collected. Personal data is data that can be used to identify you personally. This privacy policy explains what data we collect and what we use it for. It also explains how and for what purpose this is done.

We would like to point out that data transmission over the Internet (e.g., when communicating by email) can have security gaps. Complete protection of data against access by third parties is not possible.

The responsible body for data processing on this website is:

The responsible body is the natural or legal person who, alone or jointly with others, decides on the purposes and means of processing personal data (e.g., names, email addresses, etc.).

Unless a more specific storage period is specified in this privacy policy, your personal data will remain with us until the purpose for data processing no longer applies. If you assert a legitimate request for deletion or revoke your consent to data processing, your data will be deleted unless we have other legally permissible reasons for storing your personal data (e.g., tax or commercial law retention periods); in the latter case, deletion will take place after these reasons no longer apply.

If you have consented to data processing, we will process your personal data on the basis of Art. 6 (1) lit. a GDPR or Art. 9 (2) lit. a GDPR, provided that special categories of data are processed in accordance with Art. 9 (1) GDPR. In the event of express consent to the transfer of personal data to third countries, data processing is also carried out on the basis of Art. 49 (1) lit. a GDPR. If you have consented to the storage of cookies or access to information on your end device (e.g., via device fingerprinting), data processing is also carried out on the basis of Section 25(1) TDDDG.

If your data is necessary for the performance of a contract or for the implementation of pre-contractual measures, we process your data on the basis of Art. 6 (1) lit. b GDPR. Furthermore, we process your data if it is necessary to fulfill a legal obligation on the basis of Art. 6 (1) lit. c GDPR. Data processing may also be carried out on the basis of our legitimate interest pursuant to Art. 6 (1) lit. f GDPR. The relevant legal bases in each individual case are explained in the following paragraphs of this privacy policy.

As part of our business activities, we work with various external parties. In some cases, this requires the transfer of personal data to these external parties. We only disclose personal data to external parties if this is necessary for the performance of a contract, if we are legally obliged to do so (e.g., disclosure of data to tax authorities), if we have a legitimate interest in the disclosure pursuant to Art. 6 (1) lit. f GDPR, or if another legal basis permits the disclosure of data. When using processors, we only disclose our customers' personal data on the basis of a valid contract for data processing. In the case of joint processing, a contract for joint processing is concluded.

IF DATA PROCESSING IS BASED ON ART. 6 PAR. 1 LIT. E OR F OF THE GDPR, YOU HAVE THE RIGHT TO OBJECT TO THE PROCESSING OF YOUR PERSONAL DATA AT ANY TIME FOR REASONS ARISING FROM YOUR PARTICULAR SITUATION; THIS ALSO APPLIES TO PROFILING BASED ON THESE PROVISIONS. THE RESPECTIVE LEGAL BASIS ON WHICH PROCESSING IS BASED CAN BE FOUND IN THIS DATA PROTECTION DECLARATION. IF YOU OBJECT, WE WILL NO LONGER PROCESS YOUR PERSONAL DATA, UNLESS WE CAN PROVE THAT THERE ARE COMPELLING LEGITIMATE GROUNDS FOR THE PROCESSING THAT OVERRIDE YOUR INTERESTS, RIGHTS, AND FREEDOMS, OR THE PROCESSING SERVES TO ASSERT, EXERCISE OR DEFEND LEGAL CLAIMS (OBJECTION PURSUANT TO ART. 21(1) GDPR).

IF YOUR PERSONAL DATA IS PROCESSED FOR DIRECT MARKETING PURPOSES, YOU HAVE THE RIGHT TO OBJECT AT ANY TIME TO THE PROCESSING OF PERSONAL DATA CONCERNING YOU FOR THE PURPOSE OF SUCH MARKETING; THIS ALSO APPLIES TO PROFILING, INSOFAR AS IT IS RELATED TO SUCH DIRECT MARKETING. IF YOU OBJECT, YOUR PERSONAL DATA WILL NO LONGER BE USED FOR DIRECT MARKETING PURPOSES (OBJECTION PURSUANT TO ART. 21(2) GDPR).

In the event of violations of the GDPR, data subjects have the right to lodge a complaint with a supervisory authority, in particular in the Member State of their habitual residence, place of work, or place of the alleged violation. The right to lodge a complaint exists without prejudice to any other administrative or judicial remedy.

You have the right to have data that we process automatically on the basis of your consent or in fulfillment of a contract handed over to you or to a third party in a common, machine-readable format. If you request the direct transfer of the data to another controller, this will only be done if it is technically feasible.

Within the framework of the applicable legal provisions, you have the right to receive information free of charge at any time about your stored personal data, its origin and recipients, and the purpose of data processing, and, if applicable, a right to correct or delete this data. You can contact us at any time with any questions you may have about this or other topics related to personal data.

You have the right to request the restriction of the processing of your personal data. You can contact us at any time to do so. The right to restrict processing applies in the following cases:

If you dispute the accuracy of your personal data stored by us, we usually need time to verify this. For the duration of the verification, you have the right to request the restriction of the processing of your personal data.

If the processing of your personal data was/is unlawful, you can request the restriction of data processing instead of deletion.

If we no longer need your personal data, but you need it to exercise, defend, or assert legal claims, you have the right to request the restriction of the processing of your personal data instead of deletion.

If you have lodged an objection pursuant to Art. 21 (1) GDPR, a balance must be struck between your interests and ours. As long as it is not yet clear whose interests prevail, you have the right to request the restriction of the processing of your personal data.

If you contact us by email, telephone, or fax, your inquiry, including all resulting personal data (name, inquiry), will be stored and processed by us for the purpose of processing your request. We will not disclose this data without your consent.

This data is processed on the basis of Art. 6 (1) lit. b GDPR, provided that your request is related to the performance of a contract or is necessary for the implementation of pre-contractual measures. In all other cases, processing is based on our legitimate interest in the effective processing of inquiries addressed to us (Art. 6 (1) lit. f GDPR) or on your consent (Art. 6 (1) lit. a GDPR) if this has been requested; consent can be revoked at any time.

The data you send us via contact requests will remain with us until you request us to delete it, revoke your consent to its storage, or the purpose for data storage no longer applies (e.g., after your request has been processed). Mandatory legal provisions—in particular statutory retention periods—remain unaffected.
