Privacy Policy

Last updated: 5 October 2026

Short version

Every calculator on QuickTools runs entirely in your browser with JavaScript. The numbers you type are never sent to us, never stored on a server, and never sold. We do not require an account and we do not ask for your email address.

What we do not collect

We do not collect the salary, age, weight, height, dates or any other values you enter into a calculator. Those values exist only in your browser tab and disappear when you close it. We do not run server-side logging of calculator inputs.

Advertising, cookies and analytics

This version does not load advertising scripts, advertising cookies or browser analytics. Cloudflare hosts the website and may process technical request information to deliver and protect it. See Cloudflare’s privacy policy. Calculator inputs are not included in URLs or uploaded by these tools.

If advertising or analytics is enabled later, this policy will explain the service, its data use and any consent controls before that change goes live.

Third-party links

Some pages link to external services, such as tax software or government tax authority websites. We are not responsible for the privacy practices of those sites; please review their own policies.

Children

This site is not directed at children under 13 and we do not knowingly collect personal information from them.

Contact emails

If you email us, we receive the message, your email address and any information you choose to include. We use it to answer your request or investigate a correction. Please avoid sending sensitive financial or medical information.

Changes to this policy

If this policy changes, the "last updated" date above will change with it. Material changes will be noted on the homepage.
