Data you enter
Command generators and calculators process input in your browser. Diagnostic checklist state may be stored in your browser using localStorage; you can clear it with the reset button or your browser settings. Sharing a result link can put selected inputs in the URL, so check the address before sending it.
Advertising and server logs
Google AdSense may use cookies or similar technologies to deliver and measure ads. See Google advertising technologies for details and controls. The hosting provider may process standard request logs such as IP address, user agent, and request time to operate and secure the site. BlockGuide does not publish those logs.
