Software like Brave and browser-based privacy plugins that block ads and trackers are wonderful – but protection is limited to your web browsing activity.
Trackers and beacons exist beyond your browsing habits. Apps on your smartphone and tablet are designed to connect persistently over HTTP and HTTPS with servers to collect analytics data. These data collection servers are hosted by companies like Akamai, Amazon, Facebook, Google, Crashlytics and many others.
How much is too much? You have to decide on that.
