About this app

American history taught from the record, including the parts often left out.

Its 20 numbered courses cover colonization, slavery and removal, the Civil War and Reconstruction, industry and empire, the World Wars, the Cold War, civil rights and the late twentieth century.

The first 10 lessons are free. One optional one-time purchase unlocks the remaining 90 lessons. There is no subscription.

What It Costs

The first 10 lessons are free - all of US 1.1 and all of US 1.2 - and so is everything else in the app: all 60 figure profiles, the whole glossary, all 20 quizzes, the case studies, spaced review, search, notes and the widgets.

One optional in-app purchase unlocks the remaining 90 lessons. It is a one-time purchase, not a subscription. It restores on your other devices signed in to the same Google Account. There are no ads and nothing else to buy.

Scope

This is a sourced American history survey. It covers contact and conquest, slavery, removal, Jim Crow, overseas empire, the World Wars, the Cold War, covert action, civil rights and the present. Case Files identify the documents and scholarship that support each account, and the curriculum distinguishes established records from questions historians still debate.

There is no video, discussion feed or in-app cloud sync. Active progress is stored on your device and may be included in Android backup or device transfer.

Privacy

Unredacted has no in-app sign-in or ads. Lessons and reference material work offline. Progress, bookmarks, notes and review state are stored locally. Android backup or device transfer may include selected app data, depending on your settings and provider. With optional analytics, Google Analytics for Firebase receives app interactions, purchase activity, an app-installation identifier and technical information to improve the app. Analytics starts off; change Share usage analytics in Progress at any time. Notes, search text, answers and advertising identifiers are excluded. Google Play handles purchases and restores. See the privacy policy for details.
