The protection of your personal data is important to us. We process personal data only insofar as this is necessary to provide a functional website and our content and services. The processing of personal data is carried out in accordance with the General Data Protection Regulation (GDPR) and the German Federal Data Protection Act (BDSG).
This website is hosted by All-Inkl (ALL-INKL.COM - Neue Medien Münnich, Hauptstraße 68, 02742 Friedersdorf, Germany). When you visit this website, the hosting provider automatically collects and stores information in server log files that your browser transmits. These include:
This data is not merged with other data sources. The collection of this data is based on Art. 6 (1) (f) GDPR. The website operator has a legitimate interest in the technically error-free presentation and optimization of the website.
This website uses SSL encryption for security reasons. You can recognize an encrypted connection by the browser address bar changing from "http://" to "https://" and by the lock icon in your browser bar.
This website uses a cookie consent banner. Your decision (Accept or Reject) is stored in your browser's LocalStorage. This is not a cookie in the technical sense, but a local storage of your preference.
If you select "Accept", external services (see below) may be loaded. If you select "Reject", no additional external services are loaded. You can change your decision at any time via the "Cookie Settings" link in the website footer.
This website uses TelemetryDeck to analyze usage patterns. TelemetryDeck is a privacy-friendly analytics service provided by TelemetryDeck GmbH, based in Germany. No cookies are set and no personal data such as IP addresses are stored. TelemetryDeck collects anonymized usage data such as page views and referrer sources.
Usage is based on your consent (Art. 6 (1) (a) GDPR). TelemetryDeck is only loaded if you have agreed via our cookie banner. For more information, see TelemetryDeck's privacy policy: https://telemetrydeck.com/privacy/.
This website embeds videos from the YouTube platform. The provider is Google Ireland Limited, Gordon House, Barrow Street, Dublin 4, Ireland.
We use YouTube's privacy-enhanced mode (youtube-nocookie.com). According to YouTube, this mode does not store information about visitors to this website before they watch a video. However, the privacy-enhanced mode does not necessarily prevent the sharing of data with YouTube partners. For example, YouTube establishes a connection to the Google DoubleClick network regardless of whether you watch a video.
When you start a YouTube video on this website, a connection to YouTube's servers is established. This tells the YouTube server which of our pages you have visited. If you are logged into your YouTube account, you enable YouTube to associate your browsing behavior directly with your personal profile. You can prevent this by logging out of your YouTube account.
YouTube is used in the interest of an appealing presentation of our online offerings. This constitutes a legitimate interest within the meaning of Art. 6 (1) (f) GDPR. For more information on the handling of user data, see YouTube's privacy policy: https://policies.google.com/privacy.
For the sale of digital products, we use the platform Gumroad (Gumroad, Inc., 548 Market St, Suite 36099, San Francisco, CA 94104, USA). When you make a purchase via the buy button on our website, you are connected to Gumroad through an overlay. Payment processing is handled directly by Gumroad.
Personal data (e.g., email address, payment information) is processed by Gumroad. This data processing is based on Art. 6 (1) (b) GDPR (performance of a contract). Gumroad's privacy policy can be found at: https://gumroad.com/privacy.
As Gumroad is based in the USA, data may be transferred to the USA. Gumroad has committed to compliance with the EU-U.S. Data Privacy Framework.
This website uses self-hosted fonts. The font files are served directly from our own server. No connection to external font services (such as Google Fonts) is established, and no data is transmitted to third parties for font rendering.
