Privacy Policy

Last updated July 2026.

What this site collects

The calculators on this site run entirely in your browser. When you type a number into a tool, that number stays on your device and is never sent to us. There are no accounts, no sign-ups, and no forms that collect personal information anywhere on ToolBrook.

Our hosting provider (Vercel) automatically logs standard technical data for every site visit, like IP address and browser type, the way almost every website host does. We use this only for security and performance, not to identify individual visitors.

Advertising and cookies

This site uses or plans to use Google AdSense to show ads. Google and its partners may use cookies and similar technology to serve ads based on your prior visits to this and other websites. You can see and adjust how Google personalizes ads at adssettings.google.com, and read Google's own policy at policies.google.com/technologies/ads.

Affiliate links

ToolBrook is a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a way to earn fees by linking to Amazon.com. Where we link to a specific product, that link may be an affiliate link, and we may earn a small commission on qualifying purchases at no extra cost to you.

Embeddable calculators

Some calculators can be embedded on other websites via an iframe. The embedded version works the same way as the main site: calculations happen in your browser and nothing you type is sent to us.

Children's privacy

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

Changes

If how this site handles data changes, this page will be updated with a new date at the top.
