Privacy Policy
Last Updated: February 1, 2026 • Version 2.2
1. Client-Side Calculation Execution
When you enter numbers into our Length, Weight, Temperature, Volume, Energy, Area, Speed, Cubic Yard, or Concrete calculators, all arithmetic algorithms execute strictly via local client-side JavaScript. At no point are your dimensional measurements, concrete slab specifications, or formula parameters communicated across the internet to our servers.
2. Personal Information Collection
We do not require user accounts, passwords, or credit card information to use our conversion suite. If you voluntarily transmit a message via our Contact form, we collect only the name, email address, and message contents you provide to respond to your inquiry. We never sell, rent, or distribute this correspondence to third parties.
3. Cookies & Local Browser Storage
UnitConvert Hub does not use invasive tracking cookies. We may employ standard HTML5 localStorage purely to remember your preferred converter precision settings (e.g. 4 decimals vs scientific notation) and your preferred default measurement system across sessions. This data remains on your physical hardware and can be cleared at any time in your browser settings.
4. Third-Party Integrations & Analytics
To evaluate web performance, server response times, and identify broken links, we may analyze anonymized aggregate HTTP telemetry (such as browser user-agent and screen resolution). No personally identifiable information or calculation parameters are associated with this operational data.
5. Contact Information
If you have questions regarding our privacy practices or data processing policies, please submit an inquiry via our Contact Page or email privacy@unitconverthub.com.
