Your privacy matters to us
This page explains what information we collect, why we collect it, and how you can control it when using PerfCalculator.
PerfCalculator is available at perfcalculator.com. When we say “we”, “us”, or “our”, we mean PerfCalculator. When we say “you”, we mean you as a visitor or user of the website.
Our calculators are made to be simple. Most of the time, you can use tools without creating an account and without sharing personal details.
Information we collect
We collect information in two main ways: information you provide to us and information that is collected automatically when you use the site.
If you contact us by email, we receive the information you send, such as your email address and message content. We use it only to reply and help you.
Like most websites, our servers and partners may collect basic technical data when you browse. This can include your IP address, browser type, device type, pages you visit, time spent, and approximate location based on IP.
We do not ask you to enter personal identity details to use calculators. The numbers you type into calculators are primarily used to show results. We do not try to identify you from calculator inputs.
Cookies and similar technologies

How we use information
We use collected information for simple reasons:
- To operate the website and make sure calculators work properly
- To improve design, performance, and usability
- To respond to support requests and messages
- To protect the site from spam, abuse, and security threats
- To show ads and measure how ads perform on the site
Advertising and Google AdSense
We may show advertising to support the site and keep calculators free. We may use Google AdSense and similar advertising partners. These partners may use cookies to display ads, limit repeated ads, and measure ad performance.
Google and other partners may serve ads based on your visits to this site and other websites. This is sometimes called interest based advertising. You can control ad personalization in your Google account settings and you can also use industry opt out tools provided by advertising organizations.
If you prefer, you can reduce personalized advertising by adjusting your ad settings in your Google account. You can also use your browser controls to limit third party cookies.
Analytics
We may use analytics tools to understand which calculators people use, which pages load slowly, and where we should improve. Analytics typically collect usage data like page views, approximate location, device type, and performance events.
Analytics are used to improve the website experience. We do not use analytics to try to identify you personally.
When we share information
We do not sell your personal information. We only share information in limited situations:
- With trusted service providers that help run the website, such as hosting, analytics, and advertising partners
- If required by law, legal process, or to protect the safety and security of users and the website
- If we ever reorganize the site business, we may transfer necessary information as part of that change
Data retention
We keep information only as long as needed for the purposes described above. For example, email messages may be kept so we can follow up, prevent repeated issues, and improve support. Technical logs may be kept for security and performance monitoring.
Your choices
You have control over your privacy. Here are common options:
You can block cookies or delete cookies using your browser settings.
You can manage ad personalization using Google ad settings and other industry opt out tools.
If you want to ask a privacy question or request a change, email us at [email protected].
Children’s privacy
PerfCalculator is designed for a general audience. We do not knowingly collect personal information from children. If you believe a child has provided personal information, contact us and we will take appropriate steps.
Security
We use reasonable security measures to protect the website and reduce risks. However, no website can guarantee perfect security. Please use the site responsibly and avoid sending sensitive information by email.
International visitors
If you access the site from outside the country where our servers or partners operate, your information may be processed in different locations. We still handle information based on this Privacy Policy.
Changes to this policy
We may update this Privacy Policy as the site grows. When we make changes, we will update the “Last updated” date at the top of this page.
