Warning: I am not actively maintaining this app anymore. Feel free to fork this repository keeping the app name and to hijack the F-Droid app. Should you do so please drop me a note, so I'll be able to update this notice and point to your repository.
CuprumPDF is a PDF viewer based on pdf.js, which is currently the only PDF renderer written in a memory-safe language. It doesn't require any permission: the PDF to be visualized is passed to the app using Content Providers.
This is a fork of PDF Viewer, an app written by Daniel Micay and distributed with CopperheadOS. The fork was made before the license was changed from Apache 2.0 to Creative Commons Attribution-NonCommercial-ShareAlike, which is not a Free/Libre Software license due to the NonCommercial clause. The credit for the idea goes to Daniel Micay, who is also the sole copyright owner up to 93970ac.

Pull requests are welcome. Please don't submit feature requests if you're not willing to contribute with code; I'm not an Android developer, so I won't implement them. Do not rip off non-free code from Copperhead's repository. The licenses are not compatible, so new features have to be written from scratch.
