Privacy Policy

Overview

This Privacy Policy explains how FreeToolCalc collects, uses, and protects information when you visit the site. Our goal is to keep the site useful while collecting as little personal information as possible. Many calculators on the site run entirely in the browser, which means the values you type in are often processed on your device rather than stored on our servers.

Even so, websites still generate technical and advertising-related data. This policy covers calculator inputs, contact messages, cookies, analytics, and third-party advertising services such as Google AdSense so users can understand what happens behind the scenes.

Information we may collect

We may collect information in a few different ways. First, if you contact us directly, we may receive the details you choose to send, such as your name, email address, and message contents. Second, our hosting, analytics, and security systems may receive technical data such as IP address, browser type, device type, operating system, referral source, pages visited, and approximate location inferred from network information.

Calculator inputs are generally not stored as user profiles. In most cases those numbers are used only to display a result in your browser session. Some pages may still use local browser storage to remember preferences or recent settings so the tool remains easier to use when you revisit it.

Cookies, local storage, and similar technologies

FreeToolCalc uses cookies, local storage, and similar technologies for several reasons: to keep calculators working smoothly, remember user preferences, understand traffic patterns, improve page performance, measure ad delivery, and reduce abuse. Some cookies are essential for site operation, while others support analytics or advertising.

You can control cookies through your browser settings, browser extensions, or device privacy controls. Blocking some cookies may reduce convenience features, but core calculator functionality should still remain available in most cases. We also display a cookie consent banner so users can choose whether to accept broader cookie use or keep only essential storage.

Analytics and advertising

We may use analytics tools to understand which calculators and articles are useful, which devices people use, and where pages may need performance improvements. Analytics reports are generally used in aggregate rather than to identify individual visitors.

We also use third-party advertising services, including Google AdSense. AdSense and related partners may use cookies or similar technologies to serve ads, limit repeated impressions, measure ad performance, and in some cases personalize advertising based on your visit to this and other websites. Those services operate under their own terms and privacy practices. Users can review Google ad settings or use industry opt-out tools to adjust ad personalization choices.

How we use data

We use limited data to maintain the site, respond to messages, improve content quality, diagnose technical issues, protect against spam or misuse, understand broad usage patterns, and support advertising that helps keep the site free. We do not sell personal contact details submitted through direct communications. We also do not promise that every value entered into a calculator is never touched by third-party infrastructure, because security logs, browser storage, and debugging systems can still process related session information.

Your rights and choices

Depending on where you live, you may have rights to access, correct, delete, or object to the processing of certain personal information. You may also have the right to ask how your data is used, request a copy of information you sent directly to us, or withdraw consent where consent is the basis of processing. Because many site interactions are anonymous, the amount of personal data we can identify may be limited.

To make a privacy-related request, email hello@freetoolcalc.com. We may need reasonable information to verify that a request relates to data we can actually locate and manage.

Data retention, security, and children's privacy

We keep information only as long as it is reasonably necessary for the purposes described above, such as maintaining records of contact requests, protecting site security, or understanding basic performance trends. No method of storage or transmission is perfectly secure, but we aim to use reasonable safeguards that fit the scale of the site.

FreeToolCalc is intended for a general audience and is not directed specifically to children under 13. If you believe a child has sent us personal information directly, contact us and we will review the situation promptly.

Changes to this policy

We may update this policy when the site, legal requirements, or third-party services change. When that happens, we will revise the update date at the top of this page. Continued use of the site after an update means you are relying on the current version of this policy.
