About Proton Pass Android

This repository contains the source code for the Proton Pass Android application. Proton Pass is a password manager from Proton, and the app is published on Google Play, with the code opened under the GPL so that users and researchers can inspect how it works.

The topics highlight end-to-end encryption, and the app is used together with a Proton account and Proton's hosted service rather than a server you run yourself. The repository documents how to build the app locally in BUILD.md and how to contribute in CONTRIBUTING.md, and invites help with translations through a blog post.

The code and data files are licensed under version 3 or later of the GNU General Public License. The app is written in Kotlin for Android, and because it is the client side of a hosted product, it is mostly relevant to people who want to audit, build or contribute to the Android client.
