Online Privacy
The ability to control what information about you is collected, shared and inferred online.
Online privacy is not a single setting; it's the cumulative result of the tools you use, the defaults you accept and the data you produce. Practical privacy means understanding which actors can observe which behaviours, and choosing tools (ad blockers, encrypted DNS, password managers, VPNs) that reduce that observation surface.
No single tool delivers full privacy. Layered defences — block trackers in the browser, encrypt DNS, segment identities, minimise account creation — give compound protection.
