Hello Greeting

Privacy Policy

Last updated: 14 May 2026

Summary

Hello Greeting is a minimal reference app for the ChatGPT Apps SDK. It does not collect, store, share, or sell any personal data.

What the app does

Hello Greeting exposes a single tool, get_greeting. When you ask ChatGPT for a greeting, ChatGPT may call get_greeting with an optional name value parsed from your request. The app returns the string Hello, <name>! and an HTML widget that displays it.

Data we collect

None. The app collects no personal data.

• The name value passed to get_greeting is used only to build the greeting string in the immediate response. It is not stored, logged, retained, or transmitted anywhere after the response is returned.
• The app has no database, no user accounts, and no analytics.
• The app requires no authentication and has no access to your ChatGPT account, conversation history, files, or memory.

Data we share

None. The app makes no network calls to third parties. The get_greeting handler is a pure string transformation that runs entirely inside the request and contacts no external system. Its tool annotations declare this: readOnlyHint: true, openWorldHint: false, destructiveHint: false.

Hosting

The app runs as a stateless Cloudflare Worker at https://chatgpt-app.cwinnov.com/mcp. Each request is handled independently; no request data persists between requests. Cloudflare may process standard network metadata (e.g. IP address) transiently as part of delivering the request, governed by Cloudflare's privacy policy; the app itself neither reads nor retains it.

Children's privacy

The app collects no data from anyone, including children.
