Remember my progress

Your checklist and topic can be saved on this device for up to 180 days. This is off by default. Do not enable it on a shared device unless you are comfortable with others seeing that progress.

JavaScript is needed only to save or clear the guide’s local preferences. The rest of the guide remains readable without it.

Optional external tools

No estimate tool or video player loads automatically. An available external tool requires a separate, explicit “Allow and open” action for that visit. Permission is not remembered between page visits.

Advertising and analytics

The guide itself has no marketing pixels, session replay, audience analytics, or chatbot. The optional Roofle tool and its services may have their own processing after you choose to open it.

These controls govern the guide’s code. Hosting security and external websites have their own technical processing.
