Re: Tech/Syntax question
Surveillance stuff’s usually done by advertising SDKs linked to the app that do separate HTTP calls - it usually isn’t piggybacked onto functional requests. So that stuff can be filtered out in your VPN. When in doubt, route the traffic through something like Charles Proxy. If you don’t understand what you see, ditch the app!
And yes, that’s a lot of work. It’s easier to live with a small set of curated apps. It’d be nice if there was a list somewhere that did privacy ratings, and was kept up to date.
