Privacy Policy
Effective date: August 12, 2026
This policy describes what information MathBench (https://mathbench.com) collects when you use the site, and what we do with it. The short version: the calculators run entirely in your browser, we don't ask you to create an account, and the numbers you type into a calculator are never sent to us.
Calculator inputs
All calculations happen locally in your browser using JavaScript. The values you enter (measurements, loan balances, concentrations) are not transmitted to our servers, stored, or shared.
Analytics
We use Cloudflare Web Analytics to understand aggregate traffic: which pages are visited and how the site performs. Cloudflare Web Analytics does not use cookies, does not fingerprint devices, and does not track you across sites. We see counts and page-level metrics, not individual visitors.
Hosting and server logs
The site is served by Cloudflare. Like most hosting providers, Cloudflare processes standard connection data (such as IP address and user agent) to deliver pages and protect against abuse. We do not receive or retain individual visitor logs.
Advertising
We may display advertising served by Google AdSense to keep the site free. If and when ads are enabled: third-party vendors, including Google, use cookies to serve ads based on your prior visits to this and other websites. Google's use of advertising cookies enables it and its partners to serve ads based on your visits to this site and/or other sites on the internet. You may opt out of personalized advertising by visiting Google Ads Settings. Where required by law, you will be asked for consent before any advertising cookies are set.
If you email us, we keep the correspondence for as long as needed to handle your question. We don't add you to any mailing list.
Children
The site is a general-audience reference tool and does not knowingly collect personal information from children.
Changes
If this policy changes materially (for example, when advertising is enabled), we will update this page and its effective date.
