If you dispute the accuracy of your personal data stored by us, we usually need time to check this. For the duration of the review, you have the right to request that the processing of your personal data be restricted.
If the processing of your personal data was/is carried out unlawfully, you can request the restriction of data processing instead of erasure.

Google Analytics

This website uses functions of the web analysis service Google Analytics. The provider is Google Ireland Limited (“Google”), Gordon House, Barrow Street, Dublin 4, Ireland.

Google Analytics enables the website operator to analyze the behavior of website visitors. The website operator receives various usage data, such as page views, length of visit, operating systems used and origin of the user. This data is assigned to the user’s respective end device. There is no assignment to a user ID.

We can also use Google Analytics to record your mouse and scroll movements and clicks, among other things. Google Analytics also uses various modeling approaches to supplement the collected data records and uses machine learning technologies for data analysis.

Google Analytics uses technologies that enable the recognition of the user for the purpose of analyzing user behavior (e.g. cookies or device fingerprinting). The information collected by Google about the use of this website is generally transmitted to a Google server in the USA and stored there.

Meta Pixel (formerly Facebook Pixel)

This website uses the visitor action pixel from Facebook/Meta to measure conversions. The provider of this service is Meta Platforms Ireland Limited, 4 Grand Canal Square, Dublin 2, Ireland. However, according to Facebook, the data collected is also transferred to the USA and other third countries.

This allows the behavior of site visitors to be tracked after they have been redirected to the provider’s website by clicking on a Facebook ad. This allows the effectiveness of Facebook ads to be evaluated for statistical and market research purposes and future advertising measures to be optimized.

The data collected is anonymous for us as the operator of this website; we cannot draw any conclusions about the identity of the user. However, the data is stored and processed by Facebook so that a connection to the respective user profile is possible and Facebook can use the data for its own advertising purposes in accordance with the Facebook Data Usage Policy(https://de-de.facebook.com/about/privacy/). This enables Facebook to place advertisements on Facebook pages and outside of Facebook. This use of the data cannot be influenced by us as the website operator.

The use of this service is based on your consent in accordance with Art. 6 para. 1 lit. a GDPR and § 25 para. 1 TTDSG. Consent can be revoked at any time.

Insofar as personal data is collected on our website with the help of the tool described here and forwarded to Facebook, 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 GDPR). The joint responsibility is limited exclusively to the collection of data and its transfer to Facebook. The processing carried out by Facebook after forwarding is not part of the joint responsibility. The obligations incumbent on us jointly were set out in an agreement on joint processing. The text of the agreement can be found at: https://www.facebook.com/legal/controller_addendum. According to this agreement, we are responsible for providing data protection information when using the Facebook tool and for the secure implementation of the tool on our website in accordance with data protection law. Facebook is responsible for the data security of Facebook products. You can assert data subject rights (e.g. requests for information) regarding the data processed by Facebook directly with Facebook. If you assert your data subject rights with us, we are obliged to forward them to Facebook.

Data transfer to the USA is based on the standard contractual clauses of the EU Commission. Details can be found here: https://www.facebook.com/legal/EU_data_transfer_addendum and https://de-de.facebook.com/help/566994660333381.
