Terms and Conditions are a set of rules and guidelines that a user must agree
to in order to use your website or mobile app.
It acts as a legal contract between you (the company) who has the website
or mobile app and the user who access your website and mobile app.
Its up to you to set the rules and guidelines that the user must agree to.
You can think of your Terms and Conditions agreement as the legal agreement
where you maintain your rights to exclude users from your app in the
event that they abuse your app, and where you maintain your legal rights
against potential app abusers, and so on.
Terms and Conditions are also known as Terms of Service or Terms of Use.
