The growth of e-commerce has surpassed 270 million users, and personal data breaches on e-commerce platforms are extremely detrimental to users. This data can be misused by criminals, particularly those involved in fraud and social engineering, such as telemarketing, phishing/scams, password cracking, online loan account creation, and others. Data leaks have become a growing concern, raising questions about trust and privacy issues in e-commerce. This study aims to analyze e-commerce user satisfaction as influenced by trust and privacy cynicism, with the framework of expectation confirmation theory, in response to data leaks on the Tokopedia e-commerce platform in Indonesia. This research uses a quantitative approach, involving 427 active Tokopedia users from various regions in Indonesia, aged over 18 years, who have been members for at least one year. The data was analyzed using the Structured Equation Model - Partial Least Square (SEM-PLS) method with Smart PLS version 4 software. The research findings reveal that confirmation expectations have a significant relationship with perceived usefulness, trust, and satisfaction; perceived usefulness significantly affects both satisfaction and trust; trust significantly influences satisfaction; privacy cynicism also has a significant effect on both satisfaction and trust. Moreover, this study highlights the critical role of individual perceived expectations of e-commerce use in enhancing ongoing satisfaction. However, as the digital age progresses, these expectations tend to weaken as e-commerce usability improves. The findings of this study provide important insights into understanding user behavior and satisfaction in the context of e-commerce platforms and data protection.
