Privacy policy

Effective 7 October 2026. This policy covers the ngx-json-render MCP App: the MCP server at https://ngx-json-render.vercel.app/mcp and the interactive view it serves to AI clients such as Claude and ChatGPT.

What the server receives

When your AI assistant calls the render-ui tool, the server receives the UI spec the assistant wrote: component names, their props, and the data shown in them, which comes from your conversation. The server also receives standard request metadata (IP address, user agent, time).

How it is used and stored

The spec is validated and returned to your AI client in the same response so the view can render it. The server has no database, no accounts, and no cookies. It does not write specs or conversation content to disk or to logs, and it does not keep them after the response is sent. It does not use them for analytics, advertising or model training.

Third parties

• Hosting: the server runs on Vercel, which keeps standard request logs (such as IP address, URL and time) under the Vercel privacy policy.
• Fonts: the view loads the Roboto and Material Symbols fonts from Google Fonts, so Google receives your IP address and user agent under the Google privacy policy.
• Your AI client: the conversation itself, including the tool call, is handled by your AI provider under its own policy. When you press a button that sends a message, the view hands that message to your AI client as a chat message; it does not go to the server. Clients differ in how they post it: Claude puts it in the message box for you to review and send, while ChatGPT posts it to the chat at once.

We do not sell or share data with anyone else.

Retention

The server keeps nothing after a request completes. Hosting logs are kept by Vercel for its standard retention period.

Your choices

The server holds nothing about you, so there is nothing to access, correct or delete on our side. You decide when the tool is used: disconnect or disable the app in your AI client's settings to stop it entirely, and manage the conversation itself, including any tool calls in it, with your AI provider's controls. For Vercel's hosting logs, see its privacy policy above.
