+**Vanadium** is the default browser that is included with [GrapheneOS](../android.md#grapheneos), it includes a number of [patches](https://github.com/GrapheneOS/Vanadium/tree/main/patches) which assist in improving security and privacy of WebView.
+
+Vanadium is built upon the Chromium web browser project, so it should feel familiar and have minimal website compatibility issues.

 Mull comes with privacy protecting settings configured by default. You might consider configuring the **Delete browsing data on quit** options in Mull's settings if you want to close all your open tabs when quitting the app automatically, or clear other data such as browsing history and cookies automatically.
 
+#### Adblocking
+
+Currently the only way to block ads with Vanadium is to set a [DNS Resolver](../dns.md) that has this functionality. The option for that can be found in :material-dots-vertical: → **Settings** → **Privacy and security**. If you're using a VPN we suggest using your VPN provider's server.

 ## iOS
 
 On iOS, any app that can browse the web is [restricted](https://developer.apple.com/app-store/review/guidelines) to using an Apple-provided [WebKit framework](https://developer.apple.com/documentation/webkit), so there is little reason to use a third-party web browser.
