Using a particular app or service can increase your chances of staying under the radar, but doesn't guarantee your privacy or security. Not all apps are created equally, and software can have flaws- even the services highlighted here.
At the end of the day, security is a process- not a purchase. There's nothing you can install that will protect you from bad decisions and poor judgement. PrivacyHaus- nor anyone affiliated with it- can be held responsible for your personal choices.
