A user’s personal data can be anything from their user name and email address to their telephone name and physical address. Less obvious forms of sensitive data include IP addresses, log data and any information gathered through cookies, as well as users’ biometric data.

Any business whose mobile app collects personal information from users is required to have a Privacy Policy. Regardless of app geography or business domain, there are mandatory regulations such as the GDPR, the CCPA, and the PDPA, as well as Apple, Google and Android guidelines that ensure accountability and user data privacy. Some apps do not directly collect personal data but instead use a third-party tool like Google Analytics – they, too, need a Privacy Policy.
