Last updated: November 14, 2026. This policy explains how TariffCostCalc.com may process data when you visit and use its calculators.
Calculator entries
The interactive calculator is designed to perform arithmetic in your browser. You do not need an account to use it. If you use the share-link feature, entered numbers may be encoded into the URL you copy; do not share that link if the figures are commercially sensitive. Web servers and analytics systems may record visited URLs.
Technical and usage information
Like most websites, hosting providers may process IP addresses, browser type, pages requested, timestamps, and other technical logs for security and operations. If analytics or advertising services are activated, their identifiers and cookies may also be used, subject to applicable consent requirements. If you submit the contact form, we process the name, email address, subject and message you provide to respond to your inquiry, prevent spam and maintain a record when needed for support.
Cookies and third parties
See our Cookie Policy for more information. External references are operated by independent parties; their privacy practices may differ.
Retention and rights
Retention depends on hosting, security, backup, and any future analytics settings. Depending on applicable laws, you may have rights to ask about, correct, or erase personal information. This policy should be updated if new analytics, advertising, or contact systems are installed.
