You really should clear your cache frequently. How to do it varies with different browsers so CCleaner is much easier.
This site is the only thing I go to on my browser on my phone because the app sucks
I don't search much and rarely have time to do anything.
I don't even know how to Twit or Instagram or pin it
Side note
Have a friend who's a det with a local law enforcement agency
He's a little younger than me and yet had to go to "old people and technology" school to learn to twit and such so he could spy on the local youth
