Directive 95/46/EC on the protection of personal data sets rules for how people's private information (like names, addresses and phone numbers) should be handled. It is like an agreement that everyone - like governments, companies and organizations - must follow. It says that if someone has your private information, they must be careful with it and not share it with anyone else unless you say it is okay. It also means they must do their best to keep your information safe and secure. They must always ask your permission before they use it to do something, like send you a message or put it in an advertisement.
