Client Privacy refers to the protection of sensitive personal and transactional information pertaining to individuals or entities using a service. It involves measures to prevent unauthorized access, disclosure, or misuse of client data. In digital contexts, this includes safeguarding identity details, transaction histories, and communication records.
