Privacy Policy

Welcome to PureUnits ("we," "our," or "us"). We respect your privacy and are committed to protecting your personal data. This Privacy Policy explains how we collect, use, and safeguard information when you visit pureunits.com.

PureUnits is a browser-first platform. Every calculator and converter runs entirely client-side — no data you enter is ever transmitted to our servers.

• Usage Data: Automatically collected metadata — IP address, browser type, device info, and pages visited — used solely for analytics and security.
• Tool Input Data: NOT collected. All values you enter into our tools (numbers, dates, text) are processed in your browser and are never sent to any server.
• Cookie Preference: A single localStorage flag (cookie-consent) that remembers whether you accepted or declined cookies.

• Service Operations: To keep the platform available, fast, and secure.
• Analytics: Aggregate, anonymised data via Vercel Analytics to understand which tools are popular and improve UX.
• Advertising: Google AdSense uses cookies to serve contextually relevant ads. This is our primary revenue source that keeps PureUnits free.

• Essential Cookies: Required for session management and core functionality. Cannot be disabled.
• Analytics Cookies: Vercel Analytics — privacy-friendly, aggregated. Tracks page views and performance only.
• Advertising Cookies: Google AdSense — serves personalised or contextual ads based on your browsing history and preferences.

You can manage or withdraw cookie consent at any time via your browser settings or the cookie banner on our site.

• Google AdSense: Advertising network. Governed by Google's Privacy Policy at policies.google.com/privacy.
• Vercel Analytics: Web analytics. Privacy policy at vercel.com/legal/privacy-policy.
• Google Analytics: Traffic analytics. Data is anonymised and aggregated.

All communications with pureunits.com use HTTPS/TLS encryption. Since tool data never leaves your browser, the attack surface for data breaches is minimal by design.

We do not maintain user accounts or databases of personal information.

• Access: Request a copy of any personal data we hold about you.
• Correction: Ask us to correct inaccurate data.
• Deletion: Request erasure of your personal data.
• Opt-Out: Disable non-essential cookies via browser settings or our cookie banner.

Because we collect minimal data by design, most requests can be fulfilled immediately.

PureUnits is not directed at children under 13. We do not knowingly collect personal information from children. If you believe a child has provided us personal data, please contact us and we will delete it promptly.

If you have questions about this Privacy Policy or wish to exercise your rights, please reach out via our website. We aim to respond to all enquiries within 30 days.
