Privacy Policy for SGX Tracker

Last Updated: April 2026

Google API Limited Use Disclosure:
SGX Tracker's use and transfer to any other app of information received from Google APIs will adhere to the Google API Services User Data Policy, including the Limited Use requirements.

1. Data Collection and Storage

SGX Tracker does not collect, store, or transmit your personal or financial data to any server we operate. All portfolio data lives exclusively in your own cloud storage account.

Google Drive: We use the appDataFolder scope to store your portfolio files in a hidden folder that only this app can access.
OneDrive: Files are stored at /Apps/SGXTracker/.

2. Use of Google User Data

We request access to your Google account for the following purposes:

View and manage its own configuration data (Drive): To save and load your stock transactions.
View your email address: To display your identity within the app interface.

3. Data Deletion and Security

Since we do not host your data, you can delete it at any time by deleting the files from your Google Drive or OneDrive account. Authentication is handled via official OAuth 2.0 flows, meaning we never see or store your password.

4. Third-Party Sharing

We do not share your data with third parties. Stock prices are fetched via a proxy that only sees the stock symbols you are tracking, not your identity or portfolio totals.
