This website is provided through ChatGPT Sites, a service of OpenAI Ireland Limited, 1st Floor, The Liffey Trust Centre, 117–126 Sheriff Street Upper, Dublin 1, D01 YC43, Ireland. Technical delivery uses the hosting and content-delivery infrastructure engaged by OpenAI.

When the website is accessed, OpenAI and its infrastructure providers may process technically necessary connection data, in particular the IP address, date and time of access, requested content, amount of data transferred, referrer URL, browser type and operating system. This processing is necessary to deliver the website securely, reliably and efficiently. Further information is available in OpenAI’s EU Privacy Policy.

The legal basis is Article 6(1)(f) GDPR. Our legitimate interest lies in the secure, stable and efficient operation of this website. The retention period is governed by the technical and contractual policies of the providers involved.

3. Cookies, analytics and third-party content

This website uses no analytics, tracking or marketing cookies. The hosting and security infrastructure may use technically necessary cookies, for example to detect and prevent automated or abusive access. The website does not use advertising or analytics services and does not embed social-media content.

4. Contact by email or telephone

If you contact us by email or telephone, we process the information you provide to respond to your enquiry and, where applicable, to take steps towards entering into a contract. This may include your name, contact details, company, the content of your enquiry and a purchase offer.

The legal basis is Article 6(1)(b) GDPR where the processing relates to pre-contractual measures, and otherwise Article 6(1)(f) GDPR based on our legitimate interest in responding to business enquiries.

5. Recipients and disclosure

Personal data is available only to the internal or commissioned parties that require it to process the enquiry. Where necessary for technical operation, hosting or email providers may receive data as processors. Further disclosure takes place only where necessary to perform a contract, required by law or based on your consent.

6. Retention

We retain personal data only for as long as necessary to handle the enquiry, take pre-contractual steps or comply with statutory retention duties. Data is deleted when the purpose no longer applies and no retention obligation remains.

7. Your rights

Subject to the statutory requirements, you have the right to access, rectification, erasure, restriction of processing, data portability and objection. You may withdraw consent at any time with effect for the future.

8. Right to lodge a complaint

You have the right to lodge a complaint with a data-protection supervisory authority, in particular the authority responsible for your place of residence, place of work or the place of the alleged infringement.
