Privacy Policy

1. 100% Client-Side Calculation Privacy

Unlike cloud-based enterprise platforms, all calculations, dimension parameters, project areas, and material specifications entered into our tools are processed strictly within your local web browser.

We do not transmit, log, intercept, or store your project numbers, dimensions, or formula results on our servers or databases. When you refresh or close your browser tab, your entered numbers remain private to your local device.

2. Website Telemetry & Google Analytics

We use Google Analytics 4 (Measurement ID: G-NK46YX7RMV) to collect aggregated, anonymous telemetry regarding how our tools are used. This data assists us in optimizing page speed, identifying broken routes, and prioritizing new converter features.

Information collected includes:

• Browser type, operating system, and device screen resolution.
• Pages visited, referring URLs, and session duration.
• Anonymized IP addresses (IP masking enabled).

We do not correlate telemetry data with personally identifiable information.

3. Cookies and Local Preferences

We may use minimal functional cookies or browser localStorage to remember your interface preferences (such as selected unit mode or decimal precision) across visits. You can configure your browser to reject cookies without impacting the core mathematical functionality of our calculators.

4. Direct Inquiries & Personal Data

If you contact us via our contact form or email, we collect your name, email address, and message contents solely for the purpose of responding to your inquiry. Under the Protection of Personal Information Act (POPIA):

• We will never sell, rent, or trade your contact details to third-party telemarketers or advertisers.
• You have the right to request access to, rectification of, or deletion of your personal communication records at any time.
