Introduction Prompt HUD ("we", "us", or "our") is committed to protecting your privacy. This Privacy Policy explains how we collect, use, and safeguard your information when you use our Chrome extension, Prompt HUD.

We are transparent about our practices: We do not collect, store, or sell your personal data on our own servers. All data processing occurs locally on your device or directly between your browser and the third-party services you authenticate with (e.g., Google Drive, OpenAI).

01 Data Collection and Usage

1. User Content (Local Data)

• Prompts and Settings: The prompts, categories, tags, and configuration settings you create are stored locally in your browser using the Chrome storage API (chrome.storage.local). This data never leaves your device unless you explicitly enable the Cloud Sync feature.
• Clipboard History: To provide the "Clipboard" feature, the extension temporarily listens for copy events within the browser to save copied text into a local history buffer. This history is stored strictly on your local device and is not transmitted to us.
• Screenshots: When you use the screenshot feature, the image data is processed locally within your browser to allow you to attach visual context to your prompts. We do not upload these screenshots to any developer servers.

2. Cloud Sync (Google Drive)

• Google Drive Access: If you choose to enable "Cloud Sync," the extension uses the Chrome Identity API to obtain an access token for your Google Drive.
• Data Handling: We use the https://www.googleapis.com/auth/drive.file scope, which grants us access only to the specific files created by this extension. We cannot view, edit, or delete your other personal files in Google Drive.
• Purpose: This is used solely to back up your prompts and settings to a file named prompt_hud_backup.json in your Google Drive, allowing you to sync data across devices.

3. Interaction with AI Services (ChatGPT)

• Automation: The extension automates user actions on https://chatgpt.com/*. When you use the "Run" or "Fill" features, the extension injects a script to automatically fill your selected text or prompt into the ChatGPT input field.
• Data Transmission: Your prompt data is sent directly from your browser to the OpenAI (ChatGPT) website. We do not intercept, log, or store this transmission on any intermediate server.

02 Permissions

To function as intended, Prompt HUD requires the following permissions:

• storage: To save your prompts, clipboard history, and user preferences locally.
• tabs / activeTab: To inject the HUD overlay into the current tab and to capture specific page text or screenshots when you trigger an action.
• scripting: To automatically fill the text area on AI websites (e.g., ChatGPT) and interact with page content.
