I have a guaranteed way of securing your online privacy and information,
Sign out of everything, Turn off the internet and do things the old fashioned way.
Look, some services may be worse than others but in reality in today's world of convenience's you have to give something up to get what you want.
Even if you pay for it. How secure is your privacy? There seems to always be a 'Data Leak' somewhere, somehow.
So the way I see it is if you need to ditch something like Chrome, then you might as well ditch everything associated with Google. That goes the same for Apple, Microsoft, etc...
Why cut off a branch when the tree is still in your way?
