2. Collection and processing of personal data

When you visit this website, technical access data (IP address, browser type, operating system, date/time, page requested) is automatically stored by the hosting provider Cloudflare. This data is used solely to ensure operation and for error analysis.

3. Contact by e-mail or telephone

If you contact me by e-mail or telephone, your details are stored to process the enquiry and for any follow-up questions. The data is not passed on to third parties. Legal basis: Art. 6(1)(b) GDPR (steps prior to entering into a contract).

4. Hosting (Cloudflare Pages)

This website is hosted via Cloudflare Pages. Cloudflare, Inc., 101 Townsend St, San Francisco, CA 94107, USA, processes technical connection data in doing so. Details: cloudflare.com/privacypolicy

Cloudflare is certified under the EU-US Data Privacy Framework. A data processing agreement pursuant to Art. 28 GDPR is in place.

5. Fonts (self-hosted)

This website uses fonts that are delivered self-hosted on my own domain. No data is transferred to Google or other third parties. Legal basis: Art. 6(1)(f) GDPR (legitimate interest in a consistent presentation).

6. Cookies

This website does not use its own cookies for tracking or advertising purposes. Cloudflare sets technically necessary cookies for security (e.g. __cf_bm). These are required for operation and do not require consent. In addition, we store your cookie-notice acknowledgement locally in your browser (localStorage) so that you do not see the notice again on every visit — this information does not leave your device.

7. Calendly (appointment booking)

We use the Calendly service for online appointment booking. The provider is Calendly LLC, 271 17th St NW, Suite 1000, Atlanta, GA 30363, USA.

If you book an appointment via Calendly, personal data such as your name and e-mail address is collected and processed on Calendly’s servers in the USA. Legal basis: Art. 6(1)(b) GDPR (pre-contractual measures). A data processing addendum is in place with Calendly, which takes effect on acceptance of the terms of use. Calendly is certified under the EU-US Data Privacy Framework.

8. WhatsApp contact

On our website we offer the option of getting in touch via WhatsApp through a click-to-chat link. If you use this link, WhatsApp opens on your device with a pre-filled message. Your data is transmitted to WhatsApp directly via your own device — we do not store your number on our servers.

Legal basis: Art. 6(1)(b) GDPR (pre-contractual measures) and your voluntary consent pursuant to Art. 6(1)(a) GDPR. You can withdraw your consent at any time by telling us that you do not wish to receive any further messages.

Note: WhatsApp is operated by Meta Platforms Ireland Ltd. You can find information on data processing by WhatsApp in the WhatsApp privacy policy.

9. Customer reviews (ProvenExpert)

On this website, selected customer reviews originally submitted on the ProvenExpert platform (Expert Systems AG, Quedlinburger Str. 1, 10589 Berlin) are shown as static text quotations. No external widget is embedded — the review texts are placed directly in our page. As a result, no connection data is transmitted to ProvenExpert when our page is loaded.

10. Requesting the checklists (lead magnet)

If you request free documents on perini-financeandproperty.com (Checklist Property Financing Germany, Checklist Tax Non-Residents & Expats, Self-Disclosure DE/EN), we collect the following data: name, e-mail address, optionally telephone number, and the PDF documents you have selected. This data is processed exclusively for the following purposes:

• sending the requested documents by e-mail (fulfilment of your request pursuant to Art. 6(1)(b) GDPR)
• follow-up contact by Olga Nikushkina if you wish to receive further information or advice (legitimate interest pursuant to Art. 6(1)(f) GDPR)

The data is stored in our internal contact management and deleted after a maximum of 24 months without further contact. It is not passed on to third parties beyond the processors named. The e-mail is sent technically via Resend, Inc., 2261 Market Street #5039, San Francisco, CA 94114, USA (mail-server region eu-west-1, Ireland). Hosting of the website and processing of the form data is handled by Cloudflare, Inc. You can object to receiving further e-mails at any time — simply send a short message to [email protected] with the keyword “Unsubscribe”.

Note on third-country transfer: Resend, Inc. is a US provider. The transfer takes place on the basis of the EU Standard Contractual Clauses (Art. 46(2)(c) GDPR) and certification under the EU-US Data Privacy Framework. Technical mail delivery is handled via servers in the EU (Ireland).

Legal basis: your consent when submitting the form (Art. 6(1)(a) GDPR) and Art. 6(1)(b) and (f) GDPR for handling your request and any necessary follow-up contact.

11. Your rights

You have the right to access (Art. 15 GDPR), rectification (Art. 16), erasure (Art. 17), restriction of processing (Art. 18), data portability (Art. 20) and objection (Art. 21).
