Law and obligations

What a trade website has to settle legally without turning it into a project: the legal notice under section 5 DDG, a privacy policy, consent in the contact form, price information. Alongside them topics many notice late — what the German Accessibility Strengthening Act requires of whom and what it expressly does not, and how to show past work without naming the clients. Written factually and without offering legal advice; a specific case remains a matter for a lawyer.
