For OpenKeychain discussions write to this one:
As one of the main contributors besides Vincent Breitmoser, I maintain OpenKeychain.
OpenKeychain helps you communicate more privately and securely. It uses high-quality modern encryption to ensure that your messages can be read only by the people you send them to, others can send you messages that only you can read, and these messages can be digitally signed so the people getting them are sure who sent them. OpenKeychain is based on the well established OpenPGP standard making encryption compatible across your devices and operating systems.

Birthday Calendar is the first implementation to really display all contact birthdays automatically in your standard Android calendar without hassle.
Birthday Calendar provides birthdays, anniversaries, and other events from your contacts as a real calendar, which is displayed in your standard Android calendar application. To my knowledge, this is the first implementation that implements birthdays as a real calendar integrated in the Android calendar. All other apps only displays their own lists but have no real integration! Features
- Total integration of birthdays, anniversaries, and other events as a calendar
- Color picker for this birthday calendar
- Default reminder can be set in-app
Offline Calendar lets you add local calendars to Android’s Calendar app, which are not synchronized and are accessible only on the device itself.
This app allows you to import/export your calenders using ics files without using Google synchronization services.
Document Viewer is a highly customizable document viewer for Android. It supports the following formats: PDF, DjVu, EPUB, XPS, CBZ, FictionBook (fb2, fb2.zip)
The project started as a fork of EBookDroid.
I did some smaller contributions to K-9 Mail such as support for client certificates and still unfinished OpenPGP support via OpenKeychain.
I am working on unattended installations/updates for F-Droid via root access and privileged permissions.
F-Droid is an installable catalogue of FOSS (Free and Open Source Software) applications for the Android platform. The client makes it easy to browse, install, and keep track of updates on your device.
