Are you tired of using productivity apps that require account registration, unlimited permission access, and questionable privacy policies?While it's ideal to use your Android device to take notes, record audio, manage your passwords, and other productivity tasks, finding the perfect one among the millions of apps in the Google Play Store can be tricky.

In fact, four of the five open source productivity apps we've collected below don't even require you to create an account to access them.Let's take a look:
