Your traffic is HTTPS-encrypted. Why can an observer still identify you and learn a lot about your behaviour?
HTTPS encrypts the content of a connection, but your IP address and metadata (who you talk to, when, and how much) stay visible.
Every device on the Internet has an IP address that works like a postal address — it lets others trace your activity and estimate your location. Encryption doesn't change that:
- HTTPS hides what you send, but the destination IP, connection times, and data volumes are all still observable.
- A VPN masks your IP by tunnelling through a VPN server — but now the VPN provider can see everything, and metadata patterns remain.
This is the crucial lesson: metadata is data. Knowing that you connected to a crisis hotline at 3 a.m. for 20 minutes can be more revealing than the encrypted words exchanged. True anonymity requires hiding who is talking to whom, not just the message content.
Tip: Encryption protects the letter; it doesn't hide the envelope, the postmark, or that you mailed it at all.
