+
+**Vanadium** is the default browser that is included with [GrapheneOS](../android.md#grapheneos). The Chromium-based browser includes a number of [patches](https://github.com/GrapheneOS/Vanadium/tree/main/patches) which help improve the security and privacy of the WebView used by other apps.
+
+Among the numerous privacy and security enhancements listed in their documentation, Vanadium notably includes a built-in content blocker and disables JavaScript Just-In-Time (JIT) compilation by default, both of which can be toggled on a per-site basis.

+#### Recommended Vanadium Configuration
+
+<div class="annotate" markdown>
+
+As explained in their documentation, Vanadium prioritizes better privacy- and security-enhancing defaults to avoid users making themselves stand out by opting into non-default settings.
+
+You might, however, consider configuring the following privacy-related settings, all of which can be found in :material-dots-vertical: → **Settings** → **Privacy and security**.
+
+- [x] Select **Close tabs on exit**
+- [x] Select **Open external links in incognito** (1)
+- [x] Select **Lock Incognito tabs when you leave Vanadium**
+
+</div>
+
+1. With this setting enabled, **all** links from other apps, custom tabs, search intents and share intents will open in incognito tabs.
