Privacy is the most important aspect of DNSNet. Currently, DNSNet is strictly data reducing: Running it can only reduce the amount of data leaving your device, not increase it (except for fetching hosts files, obviously), as for each request, we will either allow it to leave your device or not - we will not send other requests or add other information to the request.
DNSNet does not collect and share user data to any third party. DNS requests will only be forwarded to the servers that you configure.
