Privacy & cookies

This notice explains how EasyTipMath uses optional analytics and stores your cookie choice. The calculator works whether you accept or reject analytics.

Last updated: 21 October 2026.

Calculator inputs stay in your browser

Tip and bill calculations run on your device. We do not send the amounts, percentages or number of people you enter to Google Analytics, and this website does not process payments or require an account.

Optional Google Analytics

If you select Accept analytics, we load Google Analytics 4 to measure page visits and calculator use. Google receives technical information such as browser and device details, page visits and approximate location derived from your connection. Analytics cookies help distinguish visits. Advertising personalization and Google signals are disabled in our website tag.

We record a calculator_use event for each calculator mode at most once per page visit after consent. The event identifies the mode (tip or reverse); it does not contain your bill, tip, tax or party size. We do not send query strings or URL fragments in our configured page-view URL.

Google may process data on servers outside your country. Read Google's privacy policy and how Google Analytics handles data.

Your choices and storage

Before you accept, or when you reject, this site does not load the Google Analytics script. We remember your choice in local browser storage for up to 180 days. If local storage is unavailable, we try session storage; if both are blocked, you may be asked again on another page.

With consent, Analytics can set cookies named _ga and _ga_6GQK97FYZ6, with a configured lifetime of up to 180 days. Use Cookie settings to withdraw consent. Withdrawal removes the site's Analytics cookies and reloads the page to unload Analytics. It does not erase data already sent to Google. Browser settings can also delete cookies and local storage.

Hosting and security

Cloudflare hosts this site and processes connection information, such as IP addresses and request details, to deliver and secure it. This is separate from optional Google Analytics. See Cloudflare's privacy policy.
