Data Privacy for Tools

Last reviewed: May 13, 2026 · Reviewed by: BestLaddersReview Editorial Team

Our interactive tools — quiz, reach calculator, duty rating calculator, prioritizer, setup generator, placement visualizer, safety checklist, inspection tracker, and project planner — were built to feel private by default.

What is localStorage?

localStorage is a small key/value store inside your browser. It is bound to your device and your browser profile. Nothing in localStorage leaves your machine.

What we store there

• Your most recent quiz result.
• Your most recent reach / duty calculation inputs.
• Your safety checklist tick state.
• Your inspection tracker entries (per-ladder).
• Your project planner notes (per-area).
• Your current “save to compare” basket.

What we do NOT do

• We do not POST any of that to our servers.
• We do not associate it with your email, IP, or analytics profile.
• We do not sell it. It can’t be sold — we never receive it.

How to clear it

Clear your browser’s site data (or open the site in a private window). Both will erase every tool entry.
