Online privacy concerns refer to the risks associated with sharing personal information on the internet. Many users are unaware that their data, such as browsing habits and personal details, can be collected by companies and third parties. This information can be used for targeted advertising or even sold to other entities, raising questions about consent and control over personal data. Additionally, cyber threats like hacking and identity theft pose significant risks to online privacy. Malicious actors can exploit vulnerabilities in websites and applications to access sensitive information. As a result, individuals must be cautious about the information they share and take steps to protect their online presence, such as using strong passwords and privacy settings.
