This page is about storing user data, and sharing with third parties
The site has a user registration system, aiming at a better experience in the use of text materials, making it possible to annotate and mark text, as well as record of what was read from the content, in order to: 1. resume where the reading stopped the last time the content was opened for that person and; 2. provide administrators site and authors anonymous data of readings performed. Your identity will never be transmitted to any other user of the site.
Your data is stored on Google servers, through the Firebase service (more specifically the services of Authentication, Firestore Database, and storage of Storage files), which has its own privacy policies as that link . Google is disallowed to use visitor data in any tool analytics, such as Google Analytics, Google Tag Manager, and their ad services.
Any service providers listed here are unauthorized to sell the collected information.
