Privacy Policy

Finmagine Chrome Extensions
Last Updated: February 17, 2026

1. Overview

This privacy policy covers all Chrome Extensions published by Finmagine, including:

• Finmagine Financial Chart Builder — Transforms Screener.in, Google Finance, and stockanalysis.com tables into interactive charts
• Finmagine AI Advisor — Extracts financial data from Screener.in and generates structured research prompts for AI analysis

All Finmagine extensions share the same privacy-first architecture. This policy explains our data practices.

2. Data Collection: NONE

Our extensions do NOT collect, store, or transmit any user data, including but not limited to:

• Personal information (name, email, phone, address)
• Browsing history or website usage data
• Financial data from Screener.in or any other source
• IP addresses, device identifiers, or location data
• Cookies, localStorage, or any persistent storage
• Analytics, telemetry, or usage statistics
• Authentication credentials or login information

3. How Our Extensions Work

All Finmagine extensions operate entirely locally within your browser:

Finmagine Financial Chart Builder

• Data Reading: When you visit a supported company page (Screener.in, Google Finance, or stockanalysis.com), the extension reads financial data from the HTML tables displayed on that page.
• Local Processing: All data parsing and chart generation happens in your browser using the bundled Chart.js library (included in the extension package).
• Temporary Memory Only: Financial data is held in browser memory only while you're viewing the chart. Closing the chart or navigating away clears all data immediately.

Finmagine AI Advisor

• Data Extraction: When you visit a Screener.in company page, the extension extracts financial tables, key metrics, and document links from the page.
• Local Analysis: All sector detection, health scoring, CAGR calculations, and DuPont decomposition happen entirely in your browser.
• Prompt Generation: Research prompts are assembled locally. The only moment data leaves your machine is when you choose to copy and paste a prompt into a GPT.

Common to all extensions: No data is sent to Finmagine servers, third-party services, or any external destinations. There are zero network calls.

4. Permissions Explained

Our extensions request only the minimum permissions necessary. Here's what each is used for:

Finmagine Financial Chart Builder

• activeTab: Reads financial data from the page you're currently viewing when you interact with the extension.
• Host Permissions (screener.in, google.com/finance, stockanalysis.com): Detects supported company pages and injects the visualization UI.
• scripting: Injects content scripts that create the chart interface and parse financial data from HTML tables.

Finmagine AI Advisor

• Host Permission (www.screener.in): Detects Screener.in company pages and injects the AI Advisor panel for data extraction and prompt generation.

What we DON'T request in any extension: No storage permission, no background scripts, no network access, no access to websites beyond those listed above.

5. Third-Party Services: NONE

Our extensions do not integrate with any third-party services, analytics platforms, advertising networks, or external APIs. All libraries (such as Chart.js in the Chart Builder) are bundled locally within the extension package — nothing is loaded from CDNs or external servers.

6. Changes to This Policy

If we ever update this privacy policy (which is unlikely given our zero-data design), we will:

• Update the "Last Updated" date at the top of this page
• Notify users through the Extension update notes in the Chrome Web Store
• Require explicit user consent if any data collection is introduced

7. Your Rights

Since we don't collect any data, there's nothing to access, modify, or delete. You maintain complete control over your browsing experience.

8. Compliance

This Extension complies with:

• Chrome Web Store Developer Program Policies
• GDPR (General Data Protection Regulation)
• CCPA (California Consumer Privacy Act)
• Other applicable privacy regulations

Compliance is simple because we don't handle any personal data.

10. Open Source & Transparency

All Finmagine extensions are designed with privacy as a core principle. All functionality is client-side with zero external communication. Users can inspect the extension code through Chrome's developer tools to verify these privacy claims.
