Privacy Policy
This Privacy Policy explains how the Prompt Enhancer Chrome extension (“Extension,” “we,” “us”) handles information when you use it on supported AI chat websites such as ChatGPT, Claude, Gemini, and similar services.
1. What Prompt Enhancer does
Prompt Enhancer improves the text you type into supported AI chat websites before it is sent. When you press Enter or click Send, the Extension may:
- Read the text in the chat input box
- Send that text to a Prompt Enhancer API you configure
- Replace the input with an enhanced prompt
- Submit the enhanced prompt to the chat website
2. Information we process
Depending on how you use the Extension, we may process:
- Prompt content: the text you enter into the chat box so it can be analyzed and rewritten
-
Your OpenAI API key (BYOK): if you enter it in the
Extension popup, it is stored locally in your browser
(
chrome.storage.local) and sent with enhancement requests so the API can call OpenAI on your behalf. The server is not intended to permanently store your key. - Extension settings: values such as your API URL and enhancement mode (Single or Multi)
- Technical status data: basic success/error information needed to show enhancement status in the browser
We do not intentionally collect your name, email, payment details, browsing history, or precise location through this Extension.
3. How information is used
Processed information is used only to:
- Enhance and return an improved prompt
- Apply your chosen settings (API URL and mode)
- Show status messages in the Extension UI
- Maintain and debug the enhancement service
We do not sell your personal information. We do not use your prompts for advertising.
4. Where information is sent
When enhancement runs, your prompt is sent to the Prompt Enhancer API
URL configured in the Extension popup (for local development this is
often http://localhost:3000; for production it may be a
hosted HTTPS API).
The API may use third-party AI providers (for example OpenAI, and optionally Anthropic or Google if those forwarding features are enabled) to generate the enhanced prompt. Those providers process the prompt according to their own privacy policies.
The Extension also interacts with the AI chat websites you visit (such as ChatGPT, Claude, or Gemini) only to read/replace the chat input and trigger send. Those websites process messages under their own policies.
5. Permissions and site access
The Extension requests access to supported chat websites so it can:
- Detect the chat input and send controls
- Intercept submit actions
- Insert the enhanced prompt before sending
It uses Chrome storage to save your preferences locally in your browser.
6. Data retention
- In your browser: settings remain until you clear extension data or uninstall the Extension
- On the API server: prompts are processed to generate a response. Unless you operate a custom server that stores logs, prompts are not intended to be kept as a permanent user profile
- Third-party AI providers: retention is controlled by those providers’ policies and account settings
If you self-host the API, you are responsible for your own server logs and retention practices.
7. Data sharing
We share prompt content only as needed to provide the service:
- With your configured Prompt Enhancer API
- With AI model providers used by that API to enhance prompts
- If required by law or to protect against abuse/security threats
8. Children’s privacy
Prompt Enhancer is not directed to children under 13, and we do not knowingly collect personal information from children under 13.
9. Your choices
- You can uninstall the Extension at any time
- You can change or clear the API URL and mode in the popup
- You can stop enhancement by disabling or removing the Extension
- If you self-host, you control whether prompts are logged on your server
10. Security
We take reasonable technical measures to protect data in transit and processing. No method of transmission or storage is 100% secure. Use a trusted API endpoint (preferably HTTPS in production) and protect your API keys.
11. Third-party services
This Extension interoperates with third-party services. Their handling of data is governed by their own policies, including but not limited to:
- OpenAI
- Anthropic (if enabled)
- Google (if enabled)
- The AI chat websites where the Extension runs
12. Changes to this policy
We may update this Privacy Policy from time to time. The “Last updated” date at the top will change when revisions are made. Continued use of the Extension after updates means you accept the revised policy.
