When navigating to a website known by it's name, say, your device ask specific servers - DNS servers - how to address the website. DNS is an old protocol which, except for smaller changes, hasn't been touched since its creation in 1987. Naturally the Internet changed a lot in this time, rendering the protocol outdated in some of its core aspects.

This app tackles one of the bigger problems with DNS: Encryption.
Whilst nearly all traffic on the Internet is encrypted now, DNS requests (i.e. questions for a names address) and the response aren't. This enables attackers to intercept, read and modify your requests.

Nebulo is a DNS changer which implements DNS-over-HTTPs and DNS-over-TLS and DoH3 to safely send your DNS requests to the target server. This way only you and the DNS server are able to read the requests you are sending.

Core features:
- Configure the app once and then forget about it. After initial configuration it works fully autonomous
- No ads and no tracking
- Custom servers can be used
- Low battery consumption

This app is open source. The source code can be accessed from within the app.

- Added a checkbox to not automatically alter DoH servers when creating them
- Added a mechanism to prevent firefox from using it's own DoH server
- Fix no DNS rules being deleted when no sources have been selected
