2. Accessing and hosting this website

This website is provided via ChatGPT Sites. When you access the website, the hosting provider processes connection data that is technically required. This may include your IP address, date and time of access, the page or file requested, the amount of data transferred, referrer URL, browser type, operating system and HTTP status code.

This processing is necessary to deliver the website, ensure its stability and security, and prevent misuse. The legal basis is Article 6(1)(f) GDPR. My legitimate interest is the secure and reliable operation of this website.

The hosting provider and its technical subcontractors may act as recipients or processors. Where personal data is processed outside the European Union or the European Economic Area, this is done in accordance with Articles 44 et seq. GDPR, in particular on the basis of an adequacy decision or appropriate safeguards such as the European Commission’s Standard Contractual Clauses.

Server log data is deleted or anonymised as soon as it is no longer required for the purposes stated, unless statutory retention obligations or security reasons require longer storage.

3. Cookies and analytics

Consent management with Cookiebot

This website uses the Cookiebot consent management platform provided by Usercentrics A/S, Havnegade 39, 1058 Copenhagen, Denmark. Cookiebot displays the consent dialog, stores your selection and allows you to change or withdraw your consent at a later date.

A technically necessary cookie is stored for this purpose. It may contain the consent status, the time of consent and a random identifier. Processing is necessary to implement your choice and demonstrate that consent was obtained. The legal basis is Article 6(1)(c) GDPR in conjunction with Article 7(1) GDPR and Section 25(2)(2) TDDDG.

Google Analytics 4

If you consent to the “Statistics” category, this website uses Google Analytics 4, a web analytics service provided by Google Ireland Limited, Gordon House, Barrow Street, Dublin 4, Ireland. Google Analytics helps me understand how the website is used, for example which pages are viewed, how visitors reach the website and how they interact with its content.

The data processed may include a truncated IP address, device and browser information, approximate location data, referrer URL, pages viewed, interactions, and the time and duration of use. Google Analytics uses cookies including _ga and _ga_<Container-ID>. IP anonymisation is enabled.

Google Analytics is loaded only after you have expressly consented. The legal basis is your consent pursuant to Article 6(1)(a) GDPR and Section 25(1) TDDDG. You can change or withdraw your consent at any time with effect for the future via the cookie settings.

Google may also process data in the United States. Google LLC is certified under the EU-US Data Privacy Framework. Standard Contractual Clauses approved by the European Commission may also be used. The retention period for data collected in Google Analytics is determined by the settings selected for the Analytics property; event-related data is deleted no later than the end of that retention period.

Further information is available in Google’s privacy policy and Cookiebot’s privacy policy.

4. Contact by email

If you contact me by email, I process your email address, the content of your message and any information you voluntarily provide in order to handle and respond to your enquiry.

If the enquiry relates to a potential or existing contract, the legal basis is Article 6(1)(b) GDPR. Other enquiries are processed on the basis of my legitimate interest in appropriate communication pursuant to Article 6(1)(f) GDPR.

The data is deleted once the enquiry has been fully dealt with, unless statutory retention obligations or legitimate interests require further storage. Business correspondence may be subject to statutory commercial or tax retention periods.

5. Booking appointments via meetergo

This website links to an external booking page operated by meetergo GmbH, Hauptstraße 44, 40789 Monheim am Rhein, Germany. The booking page is not embedded in this website. Your browser connects to meetergo only after you click the booking link.

When you book an appointment, the contact details you enter on the booking page, along with the information and scheduling data required for the appointment, are processed. This processing is used to handle your enquiry and organise the appointment. The legal basis is Article 6(1)(b) GDPR.

I am responsible for processing the booking data; meetergo acts as a processor in this respect. Further information about technical processing by meetergo is available in the meetergo privacy policy.

Booking data is deleted when it is no longer required to organise the appointment or for a possible subsequent business relationship, unless statutory retention obligations apply.

6. Recipients of personal data

Personal data is disclosed to service providers and other recipients only where necessary to operate the website, communicate, organise appointments or comply with legal obligations. Where required, service providers act on the basis of a data processing agreement pursuant to Article 28 GDPR.

7. Your rights

Subject to the applicable statutory requirements, you have the following rights in particular:

• Access to your personal data being processed,
• Rectification of inaccurate or incomplete data,
• Erasure of your data,
• Restriction of processing,
• Data portability,
• Withdrawal of consent with effect for the future, and
• Objection to processing based on legitimate interests.

To exercise your rights, simply email felix@nullaufeins.de.

8. Right to lodge a complaint

You have the right to lodge a complaint with a data protection supervisory authority. The authority responsible for my place of business is the State Commissioner for Data Protection and Freedom of Information of North Rhine-Westphalia. Further information is available at www.ldi.nrw.de.

9. Automated decision-making

No automated decision-making, including profiling within the meaning of Article 22 GDPR, takes place on this website.

10. Updates to this privacy policy

I will update this privacy policy if the services used, data processing activities or legal requirements change. The version published on this website at any given time applies.
