4. Third-Party Cookies
Section titled “4. Third-Party Cookies”ConstruChain Vision does not embed third-party analytics (such as Google Analytics) or marketing cookies. Hosting and authentication providers (Vercel, Supabase) keep technical access records on their infrastructure.
Optional providers may set their own cookies or storage when you use them: Google, if you sign in with Google, and Autodesk, when you open a model linked to Autodesk products in the Autodesk viewer. Dashboards published in Vision are rendered in a sandboxed frame without network access. Those providers’ cookies are governed by their own policies.
If we introduce analytics or marketing technologies in the future, we will update this policy and, where required by applicable law, request your consent before activating them.
