Have you ever talked about a new pair of sneakers, only to see ads for them on your phone later? It can feel like your phone is listening. While that’s not usually true, the reality is almost as surprising. Companies aren't recording your voice; they are just experts at tracking your online activities to predict your interests.

This is called targeted advertising, and it starts with data. Companies gather information from many sources. For instance, searching for a flight to Da Nang on a Vietnamese airline’s website signals your interest. They also see your 'likes' on social media, which websites you visit, and basic profile information. These digital footprints create a detailed picture of you.

How does an ad from a travel site appear on your social media? The answer is 'cookies.' These are small files websites store on your device to remember your actions.

Understanding how data tracking works helps you become a more aware and cautious consumer. This knowledge gives you more power to protect your digital privacy.
