One of the most popular conspiracy theories is the idea that our phones are constantly eavesdropping on us. When someone talks about something with friends and then suddenly sees ads for that exact product or service, suspicions grow stronger. But are our phones really functioning as listening devices?
In reality, smartphone microphones are not active all the time. If they were running 24/7, it would require enormous technical resources to process and store such data. Additionally, it would violate privacy laws in many countries. However, constant listening isn’t necessary—modern devices already gather enough data to make accurate predictions about our preferences.
