The Uniview app does not, and never will collect any information from users in any manner. All input to the app is processed locally on the user's phone. Text is persisted locally between runs of the app if the field is not cleared. Uniview does, however, link to a third-party website - should a user click on a glyph in-app, Uniview has no control over any data collected by that website once it opens in the user's browser.
The Uniview website (i.e. this page) relies on third-party services that Uniview has no control over.
