+AppCheck – Privacy Monitor
+==========================
+
+A pocket DNS monitor and network filter.
+
+![screenshot](doc/screenshot.png)
+
+
+## What is it?
+
+AppCheck helps you identify which applications communicate with third parties.
+It does so by logging network requests.
+AppCheck learns only the destination addresses, not the actual data that is exchanged.
+
+Your data belongs to you.
+Therefore, monitoring and analysis take place on your device only.
+The app does not share any data with us or any other third-party – unless you choose to.
+
+
+### How does it work?
+
+AppCheck creates a local VPN tunnel to intercept all network connections.
+For each connection AppCheck looks into the DNS headers only, namely the domain names.
+These domain names are logged in the background while the VPN is active.
+That means, AppCheck does not have to be active in the foreground all the time.
+
+
+## Features
+
+- See outgoing (DNS) network requests in real-time
+- See history of previous connections
+- Block unwanted traffic based on domain names
+- Record app specific activity<sup>1</sup>
+- Apply logging filters
+
+**… and soon:**
+
+- Alert Monitor & reminder
+- Occurrence Context Analysis
+- Participate in privacy research
+
+
+<sup>1</sup> Due to technical limitations, recording is not limited to any single application. Remember to force-quit all other applications before starting a recording.
+
+
+## Research Project
+
+*information will be added soon*
