Datenschutzerklärung / Privacy Policy

TODO: Replace with a full GDPR-compliant privacy policy before launch — covering the Free Business Check form, the WhatsApp contact links, and any analytics/cookies you add.

At minimum this page should cover: what data is collected (form inputs, contact details), why, how long it's stored, whether it's shared with third parties (e.g. WhatsApp/Meta), and how users can request deletion.
