2. Scope
This privacy policy applies to this CELDON LOHN marketing website. External websites opened through a link are also governed by the privacy information of the respective provider.
3. Website delivery and server logs
When you access the website, the hosting provider processes technically necessary connection data so that the website can be delivered securely and reliably. This data may include:
- the IP address of the accessing device
- the date and time of access
- the requested page or file, referrer URL, and HTTP status
- browser type, operating system, and device information
Processing is based on Article 6(1)(f) GDPR. Our legitimate interest is the secure, stable, and abuse-free operation of the website.
Log data is deleted once it is no longer needed for operation and security. It is retained for longer only where a security incident must be investigated or the law requires it.
4. Cookies, analytics, and external media
This website does not set cookies and does not use analytics, marketing, or advertising trackers. Tracking pixels and social media plugins are not used.
External hosting and content-delivery providers may be used to deliver individual media content securely and efficiently. In this process, technically required connection data, particularly the IP address, time of access, and browser and device information, is processed.
Processing is based on Article 6(1)(f) GDPR. Our legitimate interest lies in the reliable and efficient delivery of our website. We do not use this integration for analytics or marketing purposes.
5. Contact by email
If you contact us by email, we process your contact details, the content of your message, and the related communication data in order to respond to your request.
The legal basis is Article 6(1)(b) GDPR where the request concerns pre-contractual steps or a contract. In other cases, processing is based on Article 6(1)(f) GDPR and our legitimate interest in handling business enquiries.
We delete the data once your request has been fully handled and there are no statutory retention duties or legitimate reasons for continued storage.
6. External appointment booking through HubSpot
The “Book a meeting” button opens an external HubSpot appointment-booking page in a new browser tab. HubSpot content and scripts are not embedded on this website. Merely visiting this website therefore does not establish a connection to HubSpot.
The booking service is provided by HubSpot Ireland Limited, 1 Sir John Rogerson’s Quay, Dublin 2, Ireland. After you open the external link, HubSpot processes technical connection data and, if you book an appointment, the contact and appointment details you enter.
Where we receive booking data, we use it to organise the appointment and handle your enquiry. The legal basis is Article 6(1)(b) GDPR where pre-contractual steps are involved, and otherwise Article 6(1)(f) GDPR. The data is deleted when it is no longer needed for these purposes and no retention duty applies.
Where HubSpot processes data outside the European Economic Area, this may take place only under the conditions of Articles 44 et seq. GDPR, in particular on the basis of an adequacy decision or appropriate safeguards such as the EU Standard Contractual Clauses.
7. Recipients
Personal data is disclosed only to parties that need it for the purposes described above. These may include:
- hosting, email, and technical IT service providers acting on our behalf
- HubSpot when you open or use the external appointment-booking service
- public authorities or other bodies where disclosure is required by law
We do not sell personal data.
8. Your rights
Subject to the applicable legal conditions, you have the following rights in particular:
- access to your processed data under Article 15 GDPR
- rectification of inaccurate data under Article 16 GDPR
- erasure or restriction of processing under Articles 17 and 18 GDPR
- data portability under Article 20 GDPR
- objection under Article 21 GDPR to processing based on Article 6(1)(f) GDPR
- withdrawal of consent with future effect under Article 7(3) GDPR
To exercise your rights, email info@celdon.ai. We may request additional information where this is necessary to verify your identity securely.
9. Right to lodge a complaint
Under Article 77 GDPR, you have the right to lodge a complaint with a data protection supervisory authority. The Berlin Commissioner for Data Protection and Freedom of Information is the authority responsible for our registered office.

10. Security
We use appropriate technical and organisational measures to protect personal data against loss, misuse, and unauthorised access. The website is transmitted in encrypted form using HTTPS.
11. Changes to this privacy policy
We update this privacy policy when the website, the services used, or the legal requirements change. The version published on this page is the current version.
