@Back3 it promises to limit your trail, so I guess it does what it promises (it is always a good sign when companies don't make bold claims about privacy or security)
Fact of life: no software or tin-foil hat can protect your privacy nowadays, but you can make it harder to track you
a) limit usage of your data in the apps/devices you use (so your digital rights are respected) - that is where Jumbo helps you
b) put your tracking data in different baskets (e.g. use a windows PC when you use an Android-Google phone, use different browsers in different devices)
c) don't tie your hardware ID to your user ID (don't log into apps and browsers, take the hassle of logging into websites).
d) limit tagging and tracking of your digital trial by others in your social life
e) disable communications when you don't need them (e.g. Wifi, Bluetooth, Geo-location)
More privacy means more hassle and inconvenience. How often have you gone to the hassle of manually selecting to 'only allow functional cookies' when prompted (in stead of the easy ALLOW ALL)? So you need to practice safe-Hex for privacy also (as inconveniently as that is).
