How do Progressive Web Apps handle data security and user privacy?
Progressive Web Apps (PWAs) prioritize data security and user privacy by implementing several layers of protection and following industry best practices. Here are some key points: 1) HTTPS protocol: PWAs ensure that all data transmission is encrypted using HTTPS, ensuring secure communication between the user’s device and the app. 2) Service workers: PWAs use service workers to handle network requests, enabling offline capabilities while keeping the data secure. 3) Same-origin policy: PWAs adhere to the same-origin policy, which prevents scripts from accessing data from different origins, enhancing security. 4) User permission prompts: PWAs prompt users for permission before accessing sensitive device features or personal information. 5) App manifest file: PWAs use an app manifest file that specifies the app’s name, icons, and permissions, allowing users to understand and control the app’s behaviors. These measures help PWAs protect user data and maintain privacy.
