Privacy Policy

This policy describes how Business Math Lab handles information when you use this website. It is written in plain English and describes what this site's code actually does, not a generic template.

Calculator inputs

Every calculator on this site runs entirely in your browser using client-side JavaScript. The numbers you type into a calculator form are used only to compute the result shown on your screen; they are not sent to, processed by, or stored on any Business Math Lab server. Reloading the page or closing the tab clears whatever you entered.

Standard server and access logs

Like most websites, requests to this site are handled by web-server infrastructure that may process standard technical data as a normal part of delivering pages — for example, IP address, browser and user-agent string, timestamps, the URL requested, referrer, and error or security-related log entries. This is standard web-server behavior, not something this site's application code adds on top. This site does not operate a separate analytics platform, and no analytics or tracking script is loaded on any page.

Cookies and local storage

This site does not set cookies and does not use browser local storage or session storage to identify or track visitors.

Third-party services

This site does not load third-party analytics, advertising, or tracking scripts, and does not embed third-party widgets. If that changes in the future, this policy will be updated to name the service and describe what it does.

Outbound links

Some pages link to other calculators, guides, or external resources. Once you follow a link away from this site, that destination's own privacy practices apply, not this policy.

Email communications

If you email smartulethtb@gmail.com, that message and any information you choose to include in it (such as your email address or the details of an issue you're reporting) are used only to respond to you and to fix or improve the site.

Purpose of processing

Any data described above is processed only to operate, secure, and improve this website and to respond to messages sent to the contact email address — not for advertising, profiling, or resale.

Security and retention

Reasonable, standard precautions are used to keep this site and its infrastructure secure, but no website can guarantee absolute security. This policy does not promise a specific log-retention period or a guaranteed deletion timeline, since those depend on the underlying hosting and server infrastructure rather than this site's application code.

Children's privacy

This site is intended for business and professional use and is not directed at children. It does not knowingly collect information from children.

International visitors

This site is intended for an international audience. By using it, you understand that any standard server-log data described above may be processed on infrastructure located outside your own country.

Changes to this policy

This policy may be updated as the site changes. The "Last updated" date at the top of this page reflects the most recent revision.
