The article examines methods for ensuring data protection in mobile applications developed using the React Native framework, widely employed for creating cross-platform solutions. The introduction highlights the importance of ensuring security amid the growing number of mobile device users and the increasing volume of personal data processed by applications. Developers are tasked with preventing data breaches and unauthorized access to sensitive information, which requires meticulous attention at all stages of development.

The objective of the study is to analyze data protection methods. The discussion focuses on encryption, user authentication, API security, and the use of secure storage for sensitive data. Particular attention is paid to the features of applications built with React Native and the vulnerabilities inherent to this framework. The study includes a review of existing protection methods and practical implementation of recommendations in real-world projects.

The findings indicate that a comprehensive approach is essential to ensure the security of mobile applications on React Native. Implementing biometric authentication, including fingerprint and facial recognition, as well as data encryption on both client and server sides, is mandatory. Protecting interactions to prevent attacks aimed at intercepting or modifying data is also of critical importance.

The information presented in the study will be valuable to developers, information security experts, and professionals in mobile technologies.
