+### Privacy replace
+
+You can define domain to be rewrited to more "privacy friendly" alternatives, like [Invidious](https://invidious.io/)
+or [Nitter](https://nitter.net/about).
+
+To do so, just add as these extra config items, this is a sample config that rewrite URLs for Twitter, Youtube, Reddit and Medium:
+
+```toml
+[[privacy_replace]]
+domain = "youtube.com"
+replace_by  ="yewtu.be"
+[[privacy_replace]]
+domain = "twitter.com"
+replace_by = "nitter.net"

+[[privacy_replace]]
