The thing is, although yes, CA have broken the 'rules', and while it is a scandal, there are very many companies that deal in your data.
They gather it, they sell it on, they use it to track you, to advertise to you, to evaluate you for credit, for medical insurance etc and if you don't want it to happen, you need to not let them have it that data.
This means:
- Not using social media or at least nailing down your privacy setting very tightly and only to friends and family you trust.
- Not doing online surveys - these are what allow the data companies access to your thoughts, and most importantly, your friends list with all the likes, their likes etc. But if one of your friends completes a survey which allows access to their friend's list, then they are giving access to your posts too.
- Don't have store cards, loyalty emails etc. They simply harvest your data and sell it on
- Dont give out your email, DOB, postcode online unless you absolutely have to. Just becasue they ask for it, doesn't mean you have to give it to them. And even if you do, you can usually make it up.
- Have a number of email addresses - keep a primary one for serious purposes and mix it up for other stuff. You are absolutely tracked using email, so don't make it easy for them
- Use a web tracker Seriously! Ghostery, Adblocker - there are many. Pick one and use it.
- Don't log into websites using FB or twitter. If they insist, make a fake one. Seriously, you are simply opening the door to the thoughts in your head. And your friends'. It's completely insidious.
- For applications like Fitbit and My Fitness Pal, use a fake name and postcode. This is medical information you are giving away, which could be sold to insurance services. Financial and medical companies already pay a lot of money for data to profile you - don't make it easy for them.
-Beware of apps on your phone, especially free ones. Most demand access to data on your phone which is not required for the functionality of the app. If you have to use one, paying for it is often safer and again, if you can use a false name, do it.
-Virus blocker obv
-Put the location off on your phone if you don't need it.
-Don't use unsecured wireless - they harvest your data there too
