AppCheck – Privacy Monitor
|
||
==========================
|
||
|
||
A pocket DNS monitor and network filter.
|
||
|
||
|
||
|
||
|
||
## 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.
|
||
|
||
|
||
