How do I edit my company details after I've added them?

Go to your avatar (top right) → Company and update any of the same fields you filled in originally — name, address, email, phone, or emergency contact.

Changes apply to any SDS you create or publish from that point on. SDS documents you've already published keep the company details that were correct when you published them, so if you need an existing document updated too, publish a new version of it after saving your changes.
