Privacy policy

Your calculations

Every calculator on this site runs entirely in your browser. The numbers you type are processed on your own device by JavaScript that was downloaded with the page. They are not transmitted to this site or to any third party, and there is no server-side component that could receive them.

What is stored on your device

Two things may be saved in your browser's localStorage, which is storage local to your device that this site can read back on your next visit:

• Recent calculations — up to twelve, so they are still there if you return. The “Clear” button next to the list removes them immediately.
• Your currency symbol preference on the discount calculator.

This data stays on your device. It is never uploaded, and clearing your browser's site data removes it. If storage is unavailable — in a private window, for example — the calculators work exactly as normal without it.

Cookies

This site does not set cookies. There are no advertising cookies, no tracking pixels and no third-party embeds.

Analytics

No analytics service is running on this site at present, and no analytics scripts are loaded. If privacy-respecting analytics are added in future, this page will be updated before they go live to say what is collected. Any such measurement would record page visits and which calculators are used — never the numbers you enter.

Server logs

Like virtually all websites, the hosting provider that serves these pages keeps standard access logs, which typically include IP addresses, timestamps, requested URLs and browser user-agent strings. These are generated by the hosting infrastructure for security and reliability purposes, and are not used to build any profile of you.

Third-party services

Fonts are self-hosted and served from this domain, so loading a page does not make requests to Google Fonts or any other external service. The site loads no third-party scripts.

Children

This site is a general-purpose calculator and does not knowingly collect personal information from anyone, including children.

Your rights

Because no personal data is collected through this site, there is no account to access, no profile to correct and no record to delete. Data stored locally in your browser is under your control and can be cleared at any time through the “Clear” button or your browser settings.

Changes to this policy

If this policy changes, the “last updated” date above will change with it. Material changes — such as introducing analytics or advertising — will be described here before they take effect.
