What we collect
SizeChartKit is a utility-first site. We do not require account registration for core ring-size tools, and we do not ask for sensitive personal data to use standard chart, calculator, converter, and printable pages.
How data is used
Measurement values entered in interactive tools are processed to return sizing results. We use this data only to provide tool functionality. Any analytics, when enabled, are limited to aggregate, non-sensitive usage signals.
Infrastructure and logs
The site is deployed on Cloudflare Workers. Standard platform logs may be generated by infrastructure providers under their own policies.
