Website Analytics with HeyCatch

With Your consent, Our website uses HeyCatch, a web analytics service of HeyCatch, Inc., 1111B S Governors Ave STE 59736, Dover, DE 19904, USA. HeyCatch processes the data on Our behalf and on Our instructions under its Data Processing Addendum.

HeyCatch starts only after You click "Accept" in the analytics banner. Until then nothing is stored in Your browser and nothing is sent to HeyCatch. If You decline, HeyCatch stays off.

When You have consented, HeyCatch processes:

• the pages You view, the page You came from and campaign parameters in the link (such as utm_source);
• clicks and form submissions, but not what You type into form fields;
• Your IP address and the approximate location derived from it;
• device and browser data, such as browser type, operating system and screen size;
• a pseudonymous visitor ID, stored in Your browser in a cookie and in local storage, so that several page views can be recognised as one visit. The cookie expires after 365 days.

We use this data to understand how visitors use the website and to improve it. The legal basis is Your consent (Art. 6(1)(a) GDPR and § 25(1) TDDDG).

Recipients are HeyCatch and its sub-processors, including PostHog, Inc. (USA), which stores the analytics events. The current list is on the HeyCatch sub-processors page. The data is processed in the United States. HeyCatch is not certified under the EU–US Data Privacy Framework; the transfer is based on the EU Standard Contractual Clauses (Commission Decision 2021/914, Module Two), which are part of HeyCatch's Data Processing Addendum.

HeyCatch keeps the data for as long as We use the service and deletes or irreversibly anonymises it no later than two months after We stop using it.

You can withdraw Your consent at any time with effect for the future: use the "Privacy settings" link in the footer or the button below. Your choice itself is stored in Your browser's local storage, so that We do not have to ask again on every page.

Change analytics consent

Website Analytics with Rybbit

With Your consent, Our website also uses Rybbit, an open-source web analytics software. Rybbit does not run on a third-party service: it runs on a server operated on Our behalf by Bitblade Solutions UG (haftungsbeschränkt), Siemensstraße 14, 79787 Lauchringen, Germany, as Our processor. The server is hosted by Hetzner Online GmbH in Germany.

Rybbit starts only after You click "Accept" in the analytics banner, the same banner as for HeyCatch. Until then the Rybbit script is not loaded and nothing is stored in Your browser. If You decline, Rybbit stays off.

When You have consented, Rybbit processes:

• the pages You view, the page You came from and parameters in the link (such as utm_source);
• clicks on buttons and on links to other websites, and interactions with forms;
• loading-time measurements (Web Vitals) and JavaScript errors that occur on the page;
• recordings of Your visit (session replay): what the page showed, mouse movements, clicks and scrolling. Form inputs are masked and are not recorded;
• Your IP address, which is transmitted with every request and used to determine Your approximate location;
• device and browser data, such as browser type, operating system and screen size;
• a pseudonymous visitor ID, stored in Your browser's local storage, so that several page views can be recognised as one visitor. It stays until You delete it or withdraw Your consent.

We use this data to understand how visitors use the website, to find errors and to improve it. The legal basis is Your consent (Art. 6(1)(a) GDPR and § 25(1) TDDDG). The data is processed only in Germany and is not passed on to other third parties.

We keep the Rybbit data for five years and then delete it.

You can withdraw Your consent at any time with effect for the future, in the same way as for HeyCatch: with the "Privacy settings" link in the footer or the button in the HeyCatch section above. Withdrawing removes the visitor ID from Your browser.
