If you are below the legal age limit to form a binding contract (in most places, 18 years of age), you may use the apps only after you receive your parent or guardian's express consent.
All Quatrian apps do not require you to have an account in order to be used. If you have an Apple Game Center account you do get access to additional Game Center functionality such as leader boards, achievements and in some cases online play with other Game Center users. QI does not have access to the user's Game Center account settings and all changes to this account must be performed using the Apple Game Center app.
We use mobile analytics software to allow us to better understand the functionality of our apps. This 3rd party software may record information such as how often you use the software, what features you use, performance data and where the application was downloaded from, but it does not in any way associate you or your devices with this data.
