2. General information on data processing
I process personal data only to the extent necessary to provide this website and my services, or where you have given consent.
Legal bases
- Art. 6(1)(a) GDPR – consent
- Art. 6(1)(b) GDPR – performance of a contract
- Art. 6(1)(f) GDPR – legitimate interest
3. Hosting
This website is hosted by:
united-domains AG
Gautinger Straße 10

A data processing agreement under Art. 28 GDPR is in place with this provider. Servers are located in Germany / the EU.
When you access the website, so-called server log files are automatically recorded (e.g. IP address, date and time, page accessed, browser type), used to ensure secure and reliable operation.
Legal basis: Art. 6(1)(f) GDPR (legitimate interest in a secure, functioning website)
4. Self-tests on the website
This website offers two short self-tests: a general one and one specifically for people on GLP-1 therapy (e.g. Ozempic, Wegovy, Mounjaro).
Your answers are not stored.
Answers to both self-tests — including details about GLP-1 therapy, side effects, or your hunger level — are processed exclusively locally in your browser to show you an immediate assessment. They are not stored, not transmitted to me, and not shared with third parties.
Only your first name, email address, and technical details of the language version and self-test used are transmitted — and only if you actively enter them and consent to being contacted.
Purpose
Getting in touch with you and sending information about my coaching services.
Withdrawal
You can withdraw your consent at any time — informally by email to info@abnehmen-zusammen.de or via the unsubscribe link in every email. Withdrawal does not affect the lawfulness of processing carried out before it.
