Android apps often collect and share user data without permission, posing privacy risks. A study found many apps connected to hundreds of websites without user knowledge, exposing sensitive information to trackers and analytics services.
To protect privacy, minimize permissions granted to apps, avoid entering confidential information, and delete unused apps. Use a VPN, firewall, and privacy-focused apps to control network access and data sharing. Be cautious of copycat apps that may contain malware.
