Prompt Polish — Privacy Policy

Last updated: September 4, 2026

Prompt Polish is a browser extension that helps you rewrite rough prompts into clearer, more specific ones before sending them to an AI chat interface. This page explains what data the extension handles and how.

The short version

The only thing Prompt Polish ever sends anywhere is the prompt text you explicitly ask it to enhance, plus any answers you type into its clarifying questions. That text goes to Prompt Polish's own server, which forwards it to Anthropic's API to generate the rewrite. Nothing is stored, and no account, sign-in, or API key is required.

What gets sent, when, and to whom

Nothing leaves your browser until you click the "Enhance Prompt" button. When you do:

• The text currently in the input box is read from the page.
• It is sent to Prompt Polish's server at prompt-polish-api.prompt-polish.workers.dev, a Cloudflare Worker operated by this extension's developer.
• That server forwards the text to Anthropic's API, using the developer's own API key, and returns the rewritten prompt to the extension, which puts it in the input box.
• If the prompt is too vague, the extension may first ask you up to two short clarifying questions. Your answers are sent along with the prompt on the same path.

The server exists for one reason: so the API key stays server-side instead of being bundled into the extension, where anyone who installed it could extract it. It is a pass-through — it does not write your prompt text to a database, a log, or a file.

What is stored

Nothing. The extension has no settings, no account, and no API key to save — it does not use browser extension storage at all, and does not request the storage permission. It keeps no history of your prompts or rewrites. Close the tab and nothing about your prompt remains on your device.

The server keeps no database either. As with any website, Cloudflare (the hosting provider) handles standard network-level request metadata such as IP addresses and timestamps under its own privacy policy; that is infrastructure logging, and does not include your prompt text. Prompt text sent onward to Anthropic is handled under Anthropic's privacy policy.

Permissions this extension requests, and why

• Site access to claude.ai, chatgpt.com, and gemini.google.com — needed to show the enhance button on those pages, read the prompt you are drafting there, and write the rewritten version back. These are the only sites the extension runs on.
• Host access to prompt-polish-api.prompt-polish.workers.dev — the server described above, and the only outside address the extension contacts.

What we don't do

• No analytics or usage tracking
• No advertising or ad targeting
• No selling or sharing of your data with third parties
• No accounts, sign-in, or personal information collected
• No access to your browsing activity outside the supported AI chat sites
• No reading of your existing conversations — only the text sitting in the input box at the moment you click enhance

Changes to this policy

If this extension's data handling changes (for example, if a future version adds optional local history), this page will be updated and the "last updated" date above will change accordingly.
