Privacy Policy & Cookie Disclosures

At kg to Gallons (https://kgtogallons.com), we respect your digital privacy and are committed to complete transparency regarding data processing, client-side calculator operations, cookies, analytics, and advertising compliance.

1. Client-Side Computational Privacy

Our mass-to-volume calculators, density converters, flow rate tools, and propane cylinder sizing engines are architected to compute mathematical outputs entirely within your browser's local JavaScript runtime. Your numeric inputs (such as kilograms, custom densities, temperatures, or container selections) are never transmitted to our remote web servers, stored in databases, or profiled for computational surveillance.

2. Information We Collect Automatically (Log Files & Analytics)

When you access our platform, our edge hosting infrastructure (Vercel) automatically collects standard technical log information, including:

• Internet Protocol (IP) address (anonymized at network edge)
• Browser type, version, and operating system
• Referring URLs and outbound exit pages
• Date, timestamp, and HTTP response codes

We use Google Analytics 4 (Measurement ID: G-VPE6CJC9VH) with IP anonymization enabled to evaluate aggregated visitor metrics, device form factors, and regional traffic volume to optimize platform performance.

Affirmative Cookie Consent: In compliance with the European ePrivacy Directive and GDPR Article 6(1)(a), Google Analytics tracking cookies are not loaded prior to affirmative consent. When you visit our website, analytics remain dormant until you select "Accept Analytics" on our cookie notice. You can update or revoke your consent preferences at any time by clicking the Cookie Preferences button in our footer.

3. Third-Party Advertising & Cookie Disclosures (Google AdSense & Partners)

To maintain free, open-access engineering tools and reference databases, our website may display programmatic advertisements served by third-party advertising networks, including Google AdSense.

4. Local Storage & Functional Cookies

We utilize minimal browser localStorage solely to preserve non-identifying operational preferences:

• Your preferred gallon standard selection (US Liquid vs. UK Imperial vs. US Dry).
• Your preferred language locale setting across our 18 international editions.
• Calculation unit toggles (e.g., metric kilograms vs. imperial pounds).

These preferences reside solely on your device and are never synchronized with an external profile.

5. Contact Form & User Communications

If you contact our engineering desk via email or our contact form, we collect your name, email address, inquiry category, and message body exclusively to investigate and resolve your technical inquiry. We never rent, monetize, or disclose your contact information to marketing brokers. Communication records are retained only as long as necessary to fulfill peer-review audits or technical corrections.
