Make yourself expensive to track.

A free toolkit for making yourself a harder, more expensive target for surveillance and data-harvesting. The first section, Opt-Out, walks you through getting your data out of the data-broker economy by hand, without handing it to a paid service to do it for you. Guides for hardening your own devices are next.

Why this is different

• No server touches your information. This is a static page. Your name, address, and progress are stored only in this browser, never sent anywhere.
• You don't have to take our word for it. The code is open source — read it yourself, or have someone technical you trust read it.
• No account, no signup. Nothing to create, nothing to lose access to.
• The broker data is a public commons, not something this app owns — it credits and builds on prior public research, and this app is just one way to use it.

Getting started

Start with a handful, not the whole list. There are hundreds of brokers, and working through them in order of what actually matters — a few per sitting — is the difference between finishing and bouncing off. That's what the guided flow does: it picks the next batch for you, easiest and highest-value first.

Setting up a profile first is optional. It stays on this device and only pre-fills the opt-out emails and forms you send yourself, plus picks the right legal citation for your state. You can skip it, though rows that compose an email or have fields to copy will be blank until you fill it in.
