StockTracker

Information StockTracker Handles

StockTracker may access or store the following information when you choose to use the related app features:

• Portfolio information: stock symbols, share counts, purchase prices, current prices, previous close values, dividend dates, and related portfolio values imported from the StockTracker desktop app or from a portfolio file you select.
• Market data provider settings: your selected stock quote provider and, if you choose a provider that requires credentials, provider API credentials such as an Alpaca Markets API key and API secret.
• Desktop pairing details: local network share URLs and bearer tokens used to import a portfolio or provider credentials from your own StockTracker desktop app.
• Camera access: camera frames are used only to scan StockTracker pairing QR codes. StockTracker does not save photos or videos from the camera.
• Files you select: if you manually import a portfolio file, StockTracker reads the selected file so it can validate and copy the portfolio into the app's private storage.

How StockTracker Uses Information

StockTracker uses this information to provide the app's portfolio features, including:

• displaying a read-only copy of your portfolio on Android;
• calculating totals, daily changes, and capital gains on your device;
• refreshing stock quote data from the market data provider you select;
• importing portfolio data and provider credentials from your desktop app over your local network; and
• saving your portfolio and settings so the app can continue working after setup.

Sharing And Third Parties

StockTracker does not sell your information. StockTracker does not share your portfolio with a StockTracker cloud service because the Android app does not use a StockTracker cloud account or backend.

Some app features contact third-party services or user-controlled devices:

• Market data providers: when you refresh quotes, StockTracker sends the relevant stock symbols to the selected provider, such as Yahoo Quotes or Alpaca Markets. If you use Alpaca Markets, your Alpaca API credentials are used to authenticate that request.
• Your StockTracker desktop app: when you import from desktop, the Android app connects to the local network address shown by your desktop app and sends the pairing bearer token so the desktop app can authorize the transfer.
• Provider documentation links: if you open provider documentation from the app, Android opens the selected provider's website in the system browser.
• Device backup services: Android or Google backup features may back up app data depending on your device settings and operating system behavior.

Third-party services process information under their own terms and privacy policies. Review the policies for any market data provider you choose to use.

Security

Portfolio data is stored in the app's private local storage on your Android device. Provider credentials are stored using the platform secure storage APIs available through .NET MAUI. Desktop pairing uses bearer tokens, and provider credential transfers from desktop are encrypted before transfer.

No method of storage or transmission is perfectly secure. Use StockTracker only on devices and networks you trust, and keep desktop sharing enabled only while importing or syncing.

Retention And Deletion

StockTracker keeps imported portfolio data, selected provider settings, saved desktop pairing details, and saved provider credentials on your Android device until you remove them or uninstall the app.

You can delete data in these ways:

• Use Clear Portfolio in the Android app to remove the saved portfolio and desktop pairing details.
• Use Market Data Settings to clear saved provider credentials.
• Uninstall StockTracker to remove app data from the device, subject to any Android or Google backup behavior configured on your device.

StockTracker does not create app accounts, so there is no StockTracker account to delete.

Your Choices

• You can deny camera permission and use pasted pairing details instead of scanning a QR code.
• You can choose Yahoo Quotes, which does not require provider credentials, or choose an authenticated provider such as Alpaca Markets.
• You can stop using a provider at any time by changing the selected quote provider or clearing saved credentials.
• You can keep the Android app offline except when importing from desktop or refreshing quotes.

Children's Privacy

StockTracker is not directed to children. StockTracker does not knowingly collect personal information from children.

Changes To This Policy

This Privacy Policy may be updated when StockTracker's features or data practices change. The effective date above will be updated when changes are made.
