A Terms and Conditions agreement acts as a legal contract between you (the company) and the user. It's where you maintain your rights to exclude users from your app in the event that they abuse your website/app, set out the rules for using your service and note other important details and disclaimers.
Having a Terms and Conditions agreement is completely optional. No laws require you to have one. Not even the super-strict and wide-reaching General Data Protection Regulation (GDPR).
Your Terms and Conditions agreement will be uniquely yours. While some clauses are standard and commonly seen in pretty much every Terms and Conditions agreement, it's up to you to set the rules and guidelines that the user must agree to.
Terms and Conditions agreements are also known as Terms of Service or Terms of Use agreements. These terms are interchangeable, practically speaking. More rarely, it may be called something like an End User Services Agreement (EUSA).
A Terms and Conditions is not required and it's not mandatory by law.
Unlike Privacy Policies, which are required by laws such as the GDPR, CalOPPA and many others, there's no law or regulation on Terms and Conditions.
However, having a Terms and Conditions gives you the right to terminate the access of abusive users or to terminate the access to users who do not follow your rules and guidelines, as well as other desirable business benefits.
In summary, while you do not legally need a Terms and Conditions agreement, there are many many reasons for you to have one. Not only will it make your business look more professional and trustworthy, but you'll also be maintaining more control over how your users are able to interact with your platforms and content.
