Hide Visit Function for website

Hi All

I'm building a website for a domestic abuse service, and was wondering if its possible to have a function on the site that will clear the browsing history, cookies and cache etc.

At the moment, i've got a page set up that will tell users how to do it manually but I'm thinking

1. People probably won't read through it
2. To a novice user, who is probably already stressed, that's probably not the best option.

Any thoughts?
Thanks
