Features of this website

There are currently no payments or newsletter subscriptions. The website code does not include analytics or advertising trackers. Images and font files are served with the website.

Website delivery, recipients and legal bases

The website is delivered and secured through OpenAI's ChatGPT Sites using Cloudflare infrastructure. Requests involve processing your IP address, time, requested page or file, and connection information sent by your browser. This enables delivery, security and troubleshooting. The legal basis is Article 6(1)(f) GDPR and the legitimate interest in a secure, functioning website. Recipients include the platform and infrastructure providers involved in delivery and security.

Platform information and international processing

Operation of the platform may involve processing outside the European Economic Area. The platform providers explain their processing, retention rules and any transfer safeguards in their privacy notices. You can also request information about processing concerning you and the relevant safeguards using the contact details above.

Topic guide and preparation lists

Selections in the topic guide and checkmarks in the preparation lists are processed only on the page currently open. They are not sent to Gernot or stored permanently. If you wish, you can download your preparation as a text file to your device.

Your motion preference

Motion starts automatically on each new page load. You can pause the animations at any time. This preference applies to the page currently open and is not stored permanently or sent to the operator. If your device requests reduced motion, the pendulum swings more gently.

Contact and retention

An email link opens your own email application; the website does not send a message. If you contact me by email or phone, I process the contact details and content you provide to handle your enquiry. Article 6(1)(b) GDPR applies to contractual enquiries. Other enquiries rely on Article 6(1)(f) GDPR and the legitimate interest in answering them. Providing data is voluntary. Without suitable contact details and information, I may be unable to respond.

Enquiries are kept for as long as needed to handle them and, where applicable, prepare or perform a contract. Further retention depends on applicable legal obligations or the necessary protection of legal claims. Technical connection data is processed for delivery and security. Where security or error logs are created, retention follows the security or troubleshooting purpose and any legal obligations. The linked provider information additionally applies to processing for which the platform is independently responsible.

Your data protection rights

Subject to the legal conditions, you have rights of access, rectification, erasure, restriction of processing and data portability. You may withdraw consent with effect for the future. For processing based on legitimate interests, you may object on grounds relating to your particular situation. Please use the contact details above to exercise these rights.

You may complain to a data protection supervisory authority, particularly where you usually live or work or where an alleged infringement occurred. This website does not make solely automated decisions producing legal or similarly significant effects.
