## Features
### Security
DNS Firewall offers a DNS over HTTPS (DoH) service to immediately protect your DNS privacy and safeguard against DNS manipulation, a cyber attack that can block access to news sites, social media platforms, and messaging apps.
### Customizable Firewall
You can add domains to the block list, including subdomains, and customize it to fit your needs.
### Predefined Blocked Categories
We maintain and update predefined blocked categories, such as known malicious and phishing domains, several times a day to keep the block list data up-to-date.
### App/Service Blocking
You have the option to block selected apps and services.
### Your DNS query history
- Offers clear insights into your network queries. You can block or allow domains with a single tap.
- Displays the domains you're visiting, the blocked domains, and the reason for the block (e.g., ad, malicious).
- Shows the most recent DNS queries on your device via a timeline.
- DNS query history is private and can only be accessed by you.
- Can be turned off, in which case the server won't save any query data.
