DoubleScroll (the “App”) respects your privacy and is operated with due care to protect personal information. This Privacy Policy explains how user information is handled in the App and related services (collectively, the “Services”).

1. Information We Collect

The App does not collect users’ personal information (such as name, address, phone number, or email address).

The App also does not use advertising SDKs or third-party analytics tools, and therefore does not obtain identifiers intended for tracking users (such as advertising IDs).

• Caches related to display features such as ruby readings (Pinyin / Yale)
  
  

• App settings (layout options, selected books, etc.)

3. External Transmission / Sharing with Third Parties

The App does not provide, sell, or share user information with third parties.
