What is meant by a digital footprint?

A digital footprint refers to the record of a person's online activities and interactions. This includes everything from social media posts, website visits, and online purchases to data collected from various apps and services. Each of these activities leaves a trace that can be tracked and analyzed, often contributing to an individual's online persona and identity.

The concept highlights the idea that digital interactions are not ephemeral; instead, they create a lasting impression that can be accessed by others, potentially influencing privacy and security. Understanding one's digital footprint is essential in today's digital age, as it underscores the importance of being mindful of what information is shared online and how it may be used by companies, governments, and even other individuals.
