1. Introduction

This Privacy Policy explains how S.C. Market Mystery investment tracking and portfolio management ("we," "us," or "our") handles user data when you use our Google Sheets add-on. By using this add-on, you agree to the terms outlined in this policy.

2. Data Collection and Usage

Our add-on is designed to assist users with portfolio management in Google Sheets. We do not collect, store, or share any user data from their Google Sheets. However, we use certain permissions to provide the intended functionality:

- https://www.googleapis.com/auth/script.external_request: Used to fetch external market data.

- https://www.googleapis.com/auth/userinfo.email: Used only to match user emails with our internal database to verify access. We do not store or use any other user information.

We have a separate user email database where we only match the user’s email for authentication purposes. No additional personal data is collected, stored, or processed from Google Sheets.

3. Data Sharing and Third-Party Services

We do not sell, trade, or share user data with third parties. Any external requests made by the add-on are strictly for fetching market data and do not involve user-specific information.

4. Security Measures

We take reasonable measures to protect user data within Google Sheets, including:

- Ensuring email verification is performed securely without storing additional user data.

- Limiting access to only the necessary spreadsheet data.

5. User Control and Rights

As a user, you have full control over your data within Google Sheets. You can uninstall the add-on at any time to revoke its access. If you have concerns about privacy, you may contact us at scmarketmystery@gmail.com.
