Parental controls are tools and features that allow parents to manage and monitor their children's online activities. These controls can be found in various devices, such as smartphones, tablets, and computers, as well as in applications and gaming consoles. They help restrict access to inappropriate content, set screen time limits, and track usage patterns. Many platforms, like YouTube and Netflix, offer built-in parental controls to ensure a safer viewing experience for kids. Parents can customize settings based on their child's age and maturity level, providing a balance between safety and independence in the digital world.
