Overview
yPDF is an offline PDF outline editor. We are committed to protecting your privacy. This privacy policy explains how yPDF handles your data.

Network Access
yPDF may access the internet only for the following purpose:
- Word Translation — When you double-click a word in a PDF document, yPDF sends that word to an online dictionary service (iciba.com) to retrieve its Chinese translation. No other personal information is transmitted.
