How-To Guides

Every practical walkthrough on the site, grouped by what it applies to. These are the pages to work through rather than read.

Each guide states what it changes and what it does not fix. Where a guide is tied to a specific OS version or device, it says so, and where it has aged, it says that too. For the reasoning behind any of it, the subject hubs are Digital Privacy, Security, and Ubiquitous Technical Surveillance.
