Privacy and cookies
The Yantra website is a static site: no accounts, no forms and no server of its own. This page sets out what it keeps in your browser and what it sends elsewhere.

Your diagrams
The playground validates and renders in your browser. What you paste or build is not uploaded, and files made with yantra build make no network requests. The CLI, the MCP server and the Python SDK run on your own machine.
Analytics, only if you accept
The first time you visit, a banner asks whether we may use analytics cookies. If you click Accept, the site uses Google Analytics 4 to count visits and see which pages people use, and Microsoft Clarity to show clicks, scrolling and anonymised session recordings, so we can find what is confusing or broken. Both are loaded through Google Tag Manager.
If you click Reject, or do not answer, neither of them runs and no analytics cookies are set. Google Tag Manager itself still loads, so it can read your choice, but it sets no cookies of its own.
The playground is fully masked for Clarity: recordings never show a diagram you paste or build. You can change your mind at any time with , also in the footer of every page; rejecting removes the cookies below.
