A free app for Android, by Celzero.
If you’re using the internet, then you’re at risk of being monitored and tracked. This is because almost every website you visit sends some data to a server, which is then likely to be used by law enforcement or a third party for surveillance purposes.
The problem is that you have no idea whether this data is being used for surveillance or not, and you cannot check the validity of any data you receive. And if you try to check the data, then you’re risking your privacy.
This is where Rethink: DNS + Firewall comes in. It is a free, open-source firewall and monitoring app that will help you protect your data from being stolen, monitored, or used for surveillance.
It works in the background and will check for suspicious activity on your device. You don’t have to do anything else. If it detects anything malicious, it will block it.
You can open the app at any time to check the status of your device. You will be able to see all the apps that are running in the background and their network activity. You can even check the validity of the apps you’re using.
