Privacy Policy

Last updated: October 20, 2026. This policy explains what information SimpleMathCalc handles when you use the site.

Your calculator inputs

All calculations run locally in your web browser with JavaScript. The numbers you type are not transmitted to us, are not stored on our servers, and are discarded when you leave or reload the page.

Server logs and hosting

Like any website, our hosting provider may automatically record standard technical information such as IP address, browser type and the pages requested, for security and reliability. We do not use this to identify individual visitors.

Cookies and analytics

The site does not set its own cookies. We use Vercel Web Analytics, provided by our hosting company Vercel, to count page views and see which calculators are useful. It is cookie-free: it does not store anything on your device and does not track you across other websites. Each visit is grouped using a hash of the request data that is reset daily, so individual visitors cannot be identified, and the numbers you type into a calculator are never included. We see only aggregate figures such as page views, referring sites, countries and device types. You can read more in Vercel's Web Analytics privacy documentation.

Advertising

The site may display advertising in the future, for example through Google AdSense. Third-party vendors, including Google, may then use cookies to serve ads based on prior visits to this and other websites. You will be able to opt out of personalized advertising at Google's Ads Settings. This policy will be updated before any advertising is enabled.

Children

The calculators are suitable for students, and we do not knowingly collect personal information from anyone, including children under 13.

Changes

We may update this policy and will change the date above when we do. Questions can be sent via the contact page.
