Little Snitch for phone?

For Android: XPrivacy will alert you when apps attempt any type of network access and allows you to whitelist or blacklist specific hostnames or wildcards.<p>That isn&#x27;t it&#x27;s main&#x2F;only function though. From their github page: &quot;XPrivacy can prevent applications from leaking privacy-sensitive data by restricting the categories of data an application can access.&quot;<p>It is a module for the Xposed framework, and requires root.<p><a href="http:&#x2F;&#x2F;repo.xposed.info&#x2F;module&#x2F;biz.bokhorst.xprivacy" rel="nofollow">http:&#x2F;&#x2F;repo.xposed.info&#x2F;module&#x2F;biz.bokhorst.xprivacy</a><p><a href="https:&#x2F;&#x2F;github.com&#x2F;M66B&#x2F;XPrivacy" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;M66B&#x2F;XPrivacy</a>

You can use most of the ones you use for Mac, but you have to set up a proxy so that the device traffic goes to your computer. Charles supports this directly.<p><a href="http:&#x2F;&#x2F;www.charlesproxy.com&#x2F;documentation&#x2F;faqs&#x2F;using-charles-from-an-iphone&#x2F;" rel="nofollow">http:&#x2F;&#x2F;www.charlesproxy.com&#x2F;documentation&#x2F;faqs&#x2F;using-charles...</a>

That&#x27;s an (outbound) firewall for those not familiar with Little Snitch

Not for iOS (unless jailbroken)<p>Android probably has something, would need root though.
