Data privacy concerns among consumers have become one of the factors influencing brand loyalty as Pakistan's SMEs explore digital marketing progressively. Using established CFIP and IUIPC models, this study analyzes the connection between privacy concerns and customer loyalty. 200 online consumers were given an established survey, and SPSS was used to analyze the results. Results reveal a moderate negative correlation (r = -0.482, p < .01), with privacy concerns explaining 23.2% of the variance in consumer loyalty. The study shows a general lack of consumer understanding about data rights and establishes the findings within Pakistan's changing statutory framework, especially the upcoming Draft Personal Data Protection Bill (Chambers and Partners, 2025). In order to increase trust and sustained loyalty, SMEs should put in place voluntary consent procedures, open data policies, and transparent privacy dashboards. In emerging markets, this study offers empirical information to inform privacy-concerned strategies for digital marketing.
