PromptMaestro Privacy Policy

Last Updated: May 14, 2025

PromptMaestro is a free Chrome extension designed to refine user prompts on AI websites like ChatGPT, Grok, Gemini, and Claude for clearer, more effective AI responses. This Privacy Policy explains how we collect, use, store, and protect your data when you use PromptMaestro.

1. Data We Collect

• OpenRouter API Key: When you enter your OpenRouter API key, it is stored locally on your device using Chrome’s storage API (chrome.storage.local) to authenticate requests to OpenRouter’s API.
• Prompt Text: When you click “Refine Prompt,” the text you enter in supported AI websites’ input fields (e.g., a query like “how to cook pasta?”) is collected and sent to OpenRouter’s API for refinement.

2. How We Use Your Data

• API Key: Used solely to authenticate requests to OpenRouter’s API (https://openrouter.ai/api/v1/chat/completions) to refine your prompts. It is not used for any other purpose.
• Prompt Text: Sent to OpenRouter’s API to generate an improved prompt, which is displayed in the extension’s interface. The refined prompt can be copied to your clipboard. Prompt text is not stored after the refinement process.

3. Data Sharing

• OpenRouter: The API key and prompt text are sent to OpenRouter API to perform prompt refinement, as this is the core functionality of PromptMaestro. OpenRouter handling of this data is governed by their privacy policy (https://openrouter.ai/privacy).
• No Other Sharing: We do not sell, share, or transfer your data to any other third parties, except as required to provide the extension’s functionality. We do not use your data for advertising, analytics, or unrelated purposes.

4. Data Storage and Security

• API Key: Stored locally on your device using chrome.storage.local. It remains on your device and is only sent to OpenRouter during API requests. You can clear it by uninstalling the extension or clearing browser data.
• Prompt Text: Not stored persistently. It is processed in memory during refinement and discarded after the response is displayed.
• We take reasonable measures to protect your data, but no system is completely secure. Use a unique API key and avoid including sensitive information in prompts.

5. Your Rights

• You can remove your API key from PromptMaestro at any time by clearing your browser’s extension data or uninstalling the extension.
• Since we do not collect personally identifiable information, there is no account to manage or personal data to request.

6. Children’s Privacy

PromptMaestro is not intended for users under 13. We do not knowingly collect data from children.

7. Changes to This Policy

We may update this policy to reflect changes in PromptMaestro’s functionality or legal requirements. The latest version will be posted at this URL, with the “Last Updated” date revised.
