Overview

QueryLens is a Chrome browser extension designed to help users analyze webpage content for semantic relevance and lexical alignment against user-defined keywords or topics. QueryLens is built with a privacy-first approach and does not collect or sell personal data for advertising or unrelated purposes.

This Privacy Policy explains what data QueryLens accesses, when it is accessed, why it is used, who may process it, how it is stored, and how users can manage or delete their data.

What Data QueryLens Collects

QueryLens only accesses data when the user actively initiates an analysis.

When you click “Analyze,” QueryLens processes the following content from the page you are currently viewing:

  • Page title
  • Meta title and meta description
  • Headings (H1, H2, H3, etc.)
  • Paragraph text/content
  • Image alt text
  • URL of the analyzed page
  • User-entered target keywords or phrases

In addition, QueryLens may store:

  • Your OpenAI API key (if you choose to save it locally)

Important:

QueryLens does not automatically collect browsing history, monitor pages in the background, or analyze webpages unless you explicitly request it.

When Data Is Collected

Data is collected only when you choose to use QueryLens functionality, specifically when you click the Analyze button.

QueryLens does not passively monitor, scrape, or transmit website content without direct user action.

Why Data Is Collected

QueryLens uses this data solely to provide its core functionality:

  • Semantic analysis of webpage relevance
  • Lexical keyword relevance analysis
  • Topic alignment scoring
  • On-page content evaluation

This allows users to assess how well a webpage aligns with selected keywords, topics, or search intent.

Who Receives the Data

To generate semantic embeddings and similarity analysis, selected webpage content and your user-provided API request are sent directly to:

OpenAI (OpenAI API services)

OpenAI processes this data according to its own privacy and data handling policies.

QueryLens does not send or save any data to QueryLens-owned servers.

API Key Handling

If you choose to enter your OpenAI API key:

  • Your API key is stored locally in your browser using Chrome local storage
  • It is not transmitted to QueryLens or our servers
  • It is used only to authenticate requests you initiate directly with OpenAI

You may also choose not to save your API key and instead clear it after each session and re-enter it manually each session.

Data Storage

Stored locally in your browser:

  • OpenAI API key (only if saved by user)
  • User preferences/settings
  • Cached analysis data (if applicable)

QueryLens does not store:

  • Webpage content
  • Personal browsing history
  • Analysis history on external servers

QueryLens does NOT maintain any database of users, preferences, settings or analyzed pages.

How Users Can Delete Their Data

Users can delete their data at any time by:

To remove saved API key:

  • Open QueryLens
  • Clear saved API key

To fully delete all QueryLens data stored locally in your browser:

  • Uninstall the QueryLens extension from Chrome
    OR
  • Clear extension storage through Chrome extension settings

Data Security

QueryLens is designed to minimize data exposure by:

  • Using secure HTTPS connections for OpenAI API requests
  • Storing API keys locally only
  • Avoiding unnecessary permissions
  • Restricting data use to user-requested analysis only

Third-Party Services

QueryLens relies on OpenAI for semantic embedding generation. Users should review OpenAI’s privacy practices here: https://openai.com/policies/

Changes to This Privacy Policy

This Privacy Policy may be updated periodically to reflect product improvements or service changes. Updates will be posted on this page with a revised effective date.
