Cookies are small text files that get stored on your device when you visit websites. Think of them as digital sticky notes that help websites remember things about your visit – like your preferences, login status, or items you've added to a cart.
They're not programs and can't carry viruses. Most of them are actually pretty boring from a technical standpoint. But they do serve important functions that make your browsing experience smoother and help us understand how people use our cash flow management tools.
