Sharpe Privacy Policy

Effective Date: March 1, 2026

1. Our Commitment to Privacy Sharpe was built with a strict "local-first" philosophy. We believe your financial data is yours alone. This Privacy Policy explains how the Sharpe Chrome Extension interacts with your data.

2. Data Collection & Storage (We Don't Collect Your Data) Sharpe does not collect, store, transmit, or sell any of your personal information, financial data, or portfolio details. The developer of Sharpe has zero access to your data.

• Local Processing: All calculations, chart generations, and portfolio insights are processed entirely locally on your own machine within your browser.
• No Telemetry: We do not use Google Analytics or any third-party tracking software to monitor how you use the extension.

3. How the Extension Works To function, Sharpe securely reads the data already present in your active DEGIRO browser session. It only communicates with two types of servers:

• DEGIRO: To fetch your current portfolio, transaction history, and active session tokens directly from your regional DEGIRO domain (e.g., trader.degiro.nl, trader.degiro.fr, etc.).
• VWD Services: To fetch the historical price charts for your assets (via charting.vwdservices.com), which is the exact same data provider DEGIRO uses.

This communication happens directly between your browser and those services. Your data never passes through any servers owned by Sharpe.

4. Permissions Justification Sharpe requests the following browser permissions for these strict purposes:

• storage and unlimitedStorage: Used exclusively to cache historical price data locally on your machine so the extension loads faster and reduces network requests.
• windows: Used solely to open a secure popup window for the Ko-fi donation widget if you choose to support the project.

5. Changes to this Policy If we ever add features that change how data is processed, we will update this policy and notify users through the Chrome Web Store extension update notes.

6. Disclaimer: Not Financial Advice Sharpe is an analytical tool designed solely for informational and educational purposes. It does not provide financial, investment, legal, or tax advice. While Sharpe offers advanced analytics, including features like "Portfolio Grading," "Risk Adjustment," "Correlation Matrices," and "Stress-Test Scenarios," these are purely mathematical models based on historical data. They do not constitute recommendations to buy, sell, or hold any specific securities, nor are they a directive to modify your investment strategy.

You are solely responsible for your own investment decisions. The developer of Sharpe is not a registered financial advisor or broker and accepts no liability for any financial losses, damages, or decisions made based on the information, metrics, or grades generated by this extension. Always conduct your own research or consult with a certified financial professional before making investment decisions.
