Privacy policy

1. Controller

The controller responsible for processing personal data on this website is:

2. Hosting and delivery of the website

This website is delivered using Cloudflare services. The provider is:

Cloudflare, Inc.
101 Townsend Street
San Francisco, CA 94107
USA

When you visit this website, technical data necessary to transmit and securely deliver the website is processed. This may include your IP address, the date and time of access, the address requested, request information and technical information about your device and browser.

The purpose of this processing is to provide this website securely, reliably and efficiently and to protect it against misuse and attacks.

The legal basis is Article 6(1)(f) GDPR. My legitimate interest is the secure and reliable provision of my website.

Cloudflare processes data in a global network. Personal data may therefore also be processed outside the European Union or the European Economic Area, particularly in the United States. For such transfers, Cloudflare uses, among other mechanisms, the EU–U.S. Data Privacy Framework and the European Commission’s Standard Contractual Clauses.

I do not maintain my own permanent server logs about visitors to this website. Cloudflare may process technical logs and metadata for limited periods as part of providing its services.

3. Contact

Contact form

If you contact me using the contact form, the data you enter – in particular your contact details and the content of your message – is processed to handle your enquiry and respond to it.

Form entries are transmitted and technically processed through Cloudflare infrastructure (Cloudflare Workers).

Your enquiry is then forwarded to my Proton Mail inbox. I process and respond to it through my Proton email account. Details about the provider and data processing at Proton are provided in the following section on contact by email.

If your enquiry concerns entering into or performing a contract, processing is based on Article 6(1)(b) GDPR. Other enquiries are processed on the basis of Article 6(1)(f) GDPR. My legitimate interest is handling and responding to communications addressed to me.

The data is deleted when it is no longer needed to handle the enquiry and there are no statutory retention requirements or other legitimate reasons for retaining it.

Providing personal data through the contact form is neither a statutory nor a contractual requirement. However, without sufficient contact details, I may be unable to process or respond to your enquiry.

Contact by email

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

I use Proton Mail for email communication. The provider is:

Proton AG
Route de la Galaise 32
1228 Plan-les-Ouates
Geneva
Switzerland

Depending on the content of your enquiry, processing is based on Article 6(1)(b) GDPR for pre-contractual measures or performance of a contract, or on Article 6(1)(f) GDPR on the basis of my legitimate interest in handling business and other enquiries.

The European Commission recognises Switzerland as providing an adequate level of data protection.

Emails and the personal data they contain are deleted when they are no longer needed for the relevant communication or business purposes, unless statutory retention requirements or other legitimate reasons for retaining them apply.

4. Cookies, tracking and analytics

I do not use analytics, marketing or tracking services on this website, nor do I use cookies requiring consent or similar technologies to track user behaviour.

In particular, Cloudflare Web Analytics is not enabled.

5. Recipients of personal data

Where necessary for the purposes described above, personal data may be processed by the service providers I use:

• Cloudflare for providing the website and technically processing contact-form enquiries.
• Proton for email communication.

Personal data is otherwise disclosed only where there is a legal basis for doing so.

6. Your rights

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

• access your personal data under Article 15 GDPR;
• rectification of inaccurate data under Article 16 GDPR;
• erasure under Article 17 GDPR;
• restriction of processing under Article 18 GDPR;
• data portability under Article 20 GDPR; and
