# Privacy & Network

### Privacy and network settings

These settings control how your profile handles network and location data. Sites use these to detect inconsistencies with your proxy.

#### WebRTC

WebRTC is a browser feature some sites use for video calls and also probe for IP detection. This setting controls whether your profile leaks your real IP through it.

| Option     | Behavior                                                            |
| ---------- | ------------------------------------------------------------------- |
| Altered    | Reports a fake public and local IP while keeping WebRTC functional. |
| Real       | Reports your actual IP.                                             |
| Disabled   | Turns WebRTC off entirely, which can be detected by sites.          |
| Only proxy | Routes WebRTC through the proxy, depending on proxy support.        |

Keep this set to **Altered**. It keeps WebRTC working for sites that require it while hiding your real IP, which is the point of running a proxy in the first place. Switch to Disabled only if a target site flags WebRTC-altered profiles specifically.

Turn on Fill WebRTC public IP based on the IP to populate the public IP automatically from your profile's connection. Leave this on unless you need to set a specific IP value manually.

#### Geolocation

This setting controls how your profile responds when a site requests its location.

| Option | Behavior                                 |
| ------ | ---------------------------------------- |
| Prompt | Asks each time, like a normal browser.   |
| Allow  | Always grants the request automatically. |
| Block  | Always denies.                           |

Set this to **Allow** and turn on Fill location based on IP. This keeps your reported location consistent with your proxy's region, which sites commonly cross-check against IP location. Prompt adds friction with no benefit, since you already control how the profile behaves. Use Block only if your workflow never needs location and you'd rather avoid the request entirely.

#### DNS

Turn on Enable custom DNS to route your profile's DNS lookups through a custom server instead of the system default. Most profiles don't need this. Enable it only if you're troubleshooting DNS-based detection or have a specific server you need to route through.
