Portfolio and position information
This information is used to provide portfolio tracking, average cost calculations, profit and loss calculations, open and closed position tracking, analytics, exports, and related app functionality.
Pynlex does not automatically retrieve live market prices and does not provide investment advice.
Your portfolio and transaction information is primarily stored locally on your device.
Pynlex does not require users to create an account in order to use the main application features.
Users are responsible for maintaining appropriate security for their devices, backups, and exported files.
Pynlex may allow users to:
Export transaction and portfolio data
Create CSV or Excel files
Create backup files
Restore previously created backups
Exported and backup files are created at the user’s request.
Once a file is exported or shared outside the App, its security depends on the destination selected by the user.
The free version of Pynlex may display advertisements provided by Google AdMob.
Google and its advertising partners may process certain information in order to provide, measure, secure, and improve advertising services.
This may include information such as:
Device or advertising identifiers
Approximate device information
App interactions
Advertising performance information
Diagnostic information
IP address or similar technical information
Advertising behavior may depend on the user’s region, consent choices, device settings, and Google’s advertising policies.

For more information about how Google processes information, please refer to Google’s privacy policies.
Pynlex may offer optional rewarded advertisements.

Watching rewarded advertisements is optional.

Payments are processed through Google Play Billing.
Pynlex does not directly collect or store your full payment card or banking information.
