2. General information on data processing

Protecting your personal data is important to me. I process your data exclusively on the basis of the statutory provisions (GDPR, DDG). In this privacy policy I inform you about the most important aspects of data processing on my website.

3. Access data and hosting

This website is delivered via Cloudflare Pages. The provider is Cloudflare Inc., 101 Townsend St, San Francisco, CA 94107, USA. Cloudflare acts as a content delivery network (CDN) and, for technical reasons, processes your IP address and further access data. Cloudflare is used on the basis of Art. 6 (1) (f) GDPR (legitimate interest in delivering the website securely and efficiently). Cloudflare is certified under the EU-US Data Privacy Framework. You can find further information in Cloudflare's privacy policy.

When you visit my website, the web server automatically records so-called server log files. These contain:

• the page or file requested
• date and time of the request
• amount of data transferred
• notification of successful retrieval
• browser type and version
• the user's operating system
• referrer URL (the page visited before)
• the anonymised IP address of the requesting computer

This data is collected solely to ensure trouble-free operation of the website and to improve my offering. I cannot draw any conclusions about you as a person. The legal basis is Art. 6 (1) (f) GDPR (legitimate interest).

4. Fonts (hosted locally)

This website uses the typeface “Lexend”, which is hosted locally on its own server. When you open the website, no connections are made to external servers (e.g. Google) to load fonts. No data is therefore transferred to third parties.

5. Vimeo

Videos from the provider Vimeo are embedded on this website. The operator is Vimeo Inc., 555 West 18th Street, New York, New York 10011, USA.

When you visit one of my pages on which a Vimeo video is embedded, a connection to Vimeo's servers is established. The Vimeo server is told which of my pages you have visited. Vimeo also obtains your IP address. If you are logged in to your Vimeo account, you enable Vimeo to assign your browsing behaviour directly to your personal profile.

The use is based on Art. 6 (1) (f) GDPR (legitimate interest in presenting my projects attractively). You can find further information in Vimeo's privacy policy.

6. Calendly

The Calendly service is integrated on this website for booking appointments. The provider is Calendly LLC, 3423 Piedmont Road NE, Atlanta, GA 30305, USA. When you click the link to book an appointment, a connection to Calendly's servers is established. Personal data (e.g. IP address, name, email address) may be transmitted to Calendly in the process.

The use is based on Art. 6 (1) (f) GDPR (legitimate interest in straightforward appointment scheduling). You can find further information in Calendly's privacy policy.

7. Feedback form

A feedback form is available on this website through which recruiters can give anonymous feedback on my application documents. The following data is recorded: ratings (stars) for individual aspects of the application, reasons for a rejection (multiple choice) and optional free-text fields.

The data is transmitted via Google Apps Script to Google Sheets and stored there. The provider is Google Ireland Limited, Gordon House, Barrow Street, Dublin 4, Ireland (parent company: Google LLC, 1600 Amphitheatre Parkway, Mountain View, CA 94043, USA). A connection to Google's servers is established and your IP address is transmitted. Google is certified under the EU-US Data Privacy Framework.

The form does not collect personal data such as name or email address. The use is based on Art. 6 (1) (f) GDPR (legitimate interest in improving my application documents). You can find further information in Google's privacy policy.

8. Contacting me

If you contact me by email or telephone, your details, including the contact data you provide, are stored by me in order to process your enquiry and in case of follow-up questions. I do not pass this data on without your consent.

The legal basis is Art. 6 (1) (b) GDPR (pre-contractual measures) or Art. 6 (1) (f) GDPR (legitimate interest in answering enquiries).

9. Your rights

You have the following rights:

• Right of access to your stored data (Art. 15 GDPR)
