Contribute to AdGuard
We are blessed to have a community that does not only love AdGuard, but also gives back. A lot of people volunteer in various ways to make other users' experience with AdGuard better, and you can join them! We, on our part, can only be happy to reward the most active members of the community.
Alternatively we earn on AdGuard premium versions. You can give them a try and check whether they work best for your needs.
