What is collected
Contact form: name, email address, message, time of sending. A hidden honeypot field must stay empty; it exists only to reject bots. form.taxi may process technical data (for example IP address, browser identifier) for spam defence. If you write by email, ordinary email metadata applies. This website does not keep form submissions in its own database.
Contact form (form.taxi)
The form on the Contact page posts over HTTPS to form.taxi, operated by wrkt*biz Reinhard Söllradl, 4070 Eferding, Austria. Storage is in the EU. form.taxi notifies me by email; for that delivery form.taxi uses Mailjet. Submissions stay in the form.taxi archive for at most one year. There is no newsletter, no file attachments, and no Google reCAPTCHA. Details at the provider: form.taxi privacy policy.
Purpose
Answering the enquiry. No marketing, no profiling, no advertising networks.
Legal basis
GDPR Art. 6(1)(b) (pre-contractual request by email or form). GDPR Art. 6(1)(f) for abuse prevention (honeypot, spam filter).
Processors
The website is hosted in the EU. The host may process technical data (for example IP addresses in server logs) for operation and security. Contact form: form.taxi (Austria / Germany). Notification email of form messages is sent by form.taxi via Mailjet. Fonts are hosted on this site, not loaded from Google. A data processing agreement with form.taxi is in place.
Retention
Form submissions at form.taxi for at most one year; in my mailbox until the enquiry is closed, longer only if a contract follows (statutory retention). Light/dark appearance may be stored in the browser’s localStorage — a strictly necessary preference, not a tracker.
Your rights
Access, rectification, erasure, restriction, portability, objection. Complaint: Austrian Data Protection Authority, Barichgasse 40–42, 1030 Vienna, dsb.gv.at.
