Privacy Policy

Last Updated: November 27, 2025

HeuristiCheck ("we", "our", or "us") is committed to protecting your privacy. This Privacy Policy explains how our Chrome Extension collects, uses, and discloses information.

1. Data Collection & Usage

HeuristiCheck operates primarily as a client-side tool. We do not track your browsing history, collect personal data, or sell your information to third parties.

  • Webpage Content: The extension analyzes the HTML structure (DOM) of the active web page solely for the purpose of identifying usability and accessibility issues. This analysis happens locally within your browser.
  • Local Storage: Your settings (Active Heuristics preferences) and Audit History are stored locally on your device using the Chrome localStorage API. We do not have access to this data.

2. AI Features & Third-Party Services

HeuristiCheck offers optional AI-powered remediation suggestions. This feature requires you to provide your own API Key.

2.1 API Key Usage & Security

  • API Keys: Your OpenAI or Google Gemini API keys are stored locally in your browser. They are never transmitted to our servers.
  • Data Transmission: When you explicitly click the "Magic Wand" (AI Fix) button, the specific HTML code snippet of the selected element and the associated heuristic error are sent directly to the chosen AI provider (OpenAI or Google) to generate a suggestion.

Please refer to OpenAI's Privacy Policy and Google's Privacy Policy for details on how they handle API requests.

3. PDF & CSV Reports

Reports generated by HeuristiCheck are created locally within the browser using JavaScript libraries. No report data is sent to external servers.

4. Permissions

activeTab Required to scan the current page for usability issues.
scripting Required to inject the visual "Navigator" widget and "Heatmap" overlays.
storage Required to save your settings and API keys locally.
host_permissions Required to communicate with OpenAI and Google Gemini APIs only.
