Privacy Policy

CalcHub is a set of calculator tools. This page explains, plainly, what data is involved when you use it.

What's stored in your browser

Your calculation history, favorites, recent calculators, and last-used inputs are saved using your browser's localStorage. This data never leaves your device — it is not sent to us, not stored on a server, and not visible to anyone else. Clearing your browser data or using a different device/browser will reset it.

What we don't collect

• We don't require an account, email, or any personal information to use any calculator. However if you do put in your email for our newsletter, we do store your email. But you will not be subjected to any spam or selling of your information.
• We don't store the numbers you enter (income, weight, loan amounts, etc.) on any server — they stay in your browser.

Analytics

We use Google Search Console and Cloudflare Web Analytics to understand aggregate traffic (e.g., which calculators are used, which pages are popular). This collects standard usage data such as pages visited, country you're located in, device type, and referral source. It does not include the values you type into a calculator.

Cookies

Aside from analytics described above, CalcHub itself does not set cookies. Your preferences (like dark mode) and history are stored via localStorage, not cookies.

Changes to this policy

If this policy changes, the "last updated" date at the top of this page will change accordingly.
