Privacy Policy

ContSize is a static reference site. We do not require accounts, do not set tracking cookies, and do not collect or store personal data.

The site is served via Cloudflare, which processes standard server logs (IP address, user agent) for security and delivery; see Cloudflare’s privacy documentation for details. Calculators run entirely in your browser — the numbers you enter never leave your device.

If you email us, we use your address only to reply. This policy will be updated here if the site’s behaviour ever changes.
