by checking the box on a privacy page and company can legally use your data and information in all the ways disclosed no matter what

This statement is partially correct. By checking the box on a privacy page or providing consent in any other way specified by the company, you are giving them permission to use your data and information in the ways disclosed. However, it is important to note that there are certain legal obligations and restrictions that companies must adhere to when collecting and using personal data. For example, under data protection laws like the General Data Protection Regulation (GDPR) in the European Union or the California Consumer Privacy Act (CCPA) in the United States, companies must provide transparency about how they collect and use personal data, as well as offer individuals certain rights and protections regarding their data. If a company violates these laws, they can face penalties and fines. So, while giving consent allows a company to use your data, they still must follow legal requirements when doing so.
