Privacy Policy

1. 100% Client-Side Computing Architecture

All interactive mathematical calculations on Nm to Joules—including Newton-meter to Joule conversions, bolt torque clamping loads, moment of inertia simulations, and photon wavelength calculations—take place entirely within your local browser sandbox via client-side JavaScript. None of the engineering values, mechanical dimensions, or physical variables you input are ever transmitted to, stored on, or analyzed by our web servers.

2. Analytics, Cookies & Measurement Technologies

To understand overall site performance, detect technical errors, and optimize calculator user interfaces, we use Google Analytics 4 (GA4, Measurement ID: G-YQ9XR35L0Y). GA4 collects aggregated, non-personally identifiable diagnostic information such as:

• Approximate geographic region (country and city level; IP addresses are automatically anonymized before logging).
• Operating system, screen resolution, browser type, and device category (desktop, tablet, mobile).
• Aggregated page engagement metrics, session durations, and interface interactions.

You can disable analytics cookie tracking at any time by configuring your browser to block third-party cookies or by installing the official Google Analytics Opt-out Browser Add-on.

3. Third-Party Advertising & Google AdSense

We may display advertisements served by third-party advertising networks, including Google AdSense. In accordance with Google’s publisher policies and privacy mandates:

• Third-Party Vendor Cookies: Third-party vendors, including Google, use cookies and web beacons to serve advertisements based on a user's prior visits to this website or other websites across the Internet.
• Advertising Cookies & Personalization: Google's use of advertising cookies enables it and its partners to serve targeted ads to our visitors based on their visits to our site and/or other sites on the World Wide Web.
• Opting Out of Personalized Advertising: Users may opt out of personalized advertising at any time by visiting Google Ads Settings (or My Ad Center). Alternatively, you can opt out of a third-party vendor's use of cookies for personalized advertising by visiting the Digital Advertising Alliance Consumer Choice tool at www.aboutads.info or the European Interactive Digital Advertising Alliance at www.youronlinechoices.eu.
• Consent Management in the EEA, UK & Switzerland: For visitors located in the European Economic Area (EEA), the United Kingdom, and Switzerland, advertising and tracking cookies are managed strictly in accordance with Google's EU User Consent Policy through an IAB Europe Transparency and Consent Framework (TCF v2.2) certified Consent Management Platform (CMP). No advertising cookies are stored or activated until explicit consent is given where legally mandated.

4. Local Storage Usage

We utilize standard HTML5 LocalStorage solely to persist your user experience preferences across browser sessions:

• nm_theme: Remembers your dark mode / light mode interface selection.
• nm_cookie_consent: Stores your cookie preference status to prevent recurring consent prompts.
• Temporary calculator UI state (e.g., active conversion tab selection).

LocalStorage data resides strictly on your local hardware device and can be purged at any time by clearing your browser cache.

5. Contact Inquiries & Personal Data Handling

If you voluntarily contact our engineering desk via email or our contact form, we process your name, email address, and message text exclusively to evaluate your technical inquiry, verify calculation formulas, or report bug fixes. We do not sell, rent, commercialize, or share your contact details with any third parties or marketing networks. Inquiries are retained only as long as necessary to fulfill the technical correspondence.

6. Your Rights Under GDPR, UK GDPR, and CCPA

Depending on your jurisdiction (including the European Economic Area, the United Kingdom, and California), you possess specific legal rights regarding personal data:

• Right of Access: You may request confirmation of any correspondence or data we hold.
• Right to Rectification or Erasure: You may request the immediate deletion of past email correspondence.
