Privacy Policy

Overview

HomeCalcTool ("we", "us", "our") operates HomeCalcTool, a free construction and home improvement calculator site. This page explains what data is collected when you use our site, who collects it, and why. We do not sell your data. We do not create user accounts. We do not store anything you type into our calculators.

What We Never Collect

• Calculator inputs: all math runs in your browser and is never sent to our servers
• Account credentials: this site has no login or registration
• Payment information: we sell nothing directly
• Names, addresses, or personal details (unless you voluntarily submit our contact form)

Calculator Inputs and localStorage

Numbers you enter into any calculator are processed entirely in your browser using JavaScript. Nothing you type is transmitted to our servers. To make the experience more convenient, we save your most recent inputs to your browser's localStorage so the calculator remembers your last values when you return. This data never leaves your device. You can clear it at any time by clearing your browser's site data for HomeCalcTool.

Google Analytics 4

We use Google Analytics 4 (GA4), operated by Google LLC, to understand which pages and calculators are most useful. GA4 collects anonymized usage data including page views, session duration, device type, browser, and approximate location (country and city level). This data is associated with a randomly generated analytics ID, not with you personally.

We have enabled IP anonymization so Google does not store full IP addresses. Data collected by GA4 is governed by Google's Privacy Policy .

GA4 sets two cookies on your device:

• _ga: distinguishes users. Expires after 2 years.
• _ga_<ID>: maintains session state. Expires after 2 years.

You can opt out of Google Analytics tracking by installing the Google Analytics Opt-out Browser Add-on .

AdSense uses cookies and similar technologies to show ads that may be relevant to your interests based on your activity on this and other websites. Google's use of advertising cookies is governed by the Google Advertising Privacy Policy . You can opt out of personalized advertising at Google Ads Settings .

Vercel processes network requests to serve pages to your browser and may log standard request data including IP addresses, request timestamps, and HTTP headers for security and performance purposes.
