Privacy Tools

Privacy tooling covers a wide span — browsers and extensions, tracker and content blocking, encrypted messaging and mail, virtual private networks, data removal services and metadata scrubbers. The category attracts strong claims, so the useful discipline is to be specific about what a given tool actually protects against.

Content and tracker blocking is the highest-value, lowest-effort item, and its benefits extend past privacy: pages load faster and use less data. A good blocker at the browser level stops the majority of cross-site tracking with no ongoing effort. Blocking at the network level, for a whole home, catches devices that have no browser and cannot be configured, which is increasingly most of them.

Virtual private networks are the most oversold product in this space. What one does is move the party who can see your traffic destinations from your network provider to the operator, and change your apparent location. What it does not do is make you anonymous, prevent tracking by sites you log into, or protect against most of what people are actually worried about. There are genuine uses — untrusted networks, circumventing regional blocks, keeping browsing from a network operator — and buying one as general-purpose protection is a misunderstanding.

Encrypted messaging is straightforwardly good and the thing to check is what is encrypted. End-to-end encrypted content is standard; metadata — who you talked to, when and how often — frequently is not, and metadata is often more revealing than content. Tools that minimise what they retain about the graph are doing the harder and more meaningful work.

Data removal services, which request deletion from data brokers on your behalf, deliver partial and temporary results. Brokers re-acquire, and the population of brokers changes. They are worth it for people with a specific safety concern and oversold as general hygiene.

The general principle worth more than any tool: privacy is determined mostly by how much data exists about you, and reducing collection beats protecting what has been collected. Fewer accounts, fewer permissions granted, fewer apps with location access. See [password managers](/categories/password-managers) for the account security half.
