Site information
Privacy & product links
A simple explanation of how this edition works.
Your entries
The finder and calculator process entries in your browser. This edition does not send those inputs to a server, collect email addresses, use analytics scripts or store entries in cookies or local storage. Reloading the page resets the controls.
External websites
Manufacturer links open a different website with its own privacy practices and terms. We do not process orders or payments. Product questions, deliveries and returns are handled by the merchant you choose.
Hosting
The service delivering a hosted copy may process ordinary connection information, such as IP address and request logs. The on-page tools themselves do not add advertising or visitor-tracking services.
Commercial disclosure
The labelled SUNLU purchase links include an affiliate identifier and a SpoolSignal source label. After you follow one, SUNLU and its affiliate provider may use cookies or similar technology to attribute a qualifying purchase and calculate commission. Their privacy policies apply on their websites. The other manufacturer links currently have no commission tracking. No affiliate tracking script is installed on SpoolSignal itself.
