Privacy Policy

In short: numbers you type into a calculator stay in your browser. We have no user accounts, no advertising and no analytics tracking. Like any website, our hosting and security providers process basic technical data, such as your IP address, to deliver pages safely.

Who We Are

This website, calc-solver.co (“CalcSolver”, “we”, “us”), is an independent site offering free online calculators. For any privacy question, email [email protected].

Calculator Inputs

Every calculator on this site runs in JavaScript inside your browser. The expressions, numbers, heights, weights, grades and amounts you enter are processed on your device. They are not sent to our server, not stored in a database, and not shared with anyone. Calculator history lasts only until you close or reload the page.

Information We Do Process

• Technical request data. When your browser loads a page, our web host and our security and delivery network (Cloudflare) receive standard request information: IP address, browser type, device type, the page requested, the referring page and the time. This is used to deliver the site, prevent abuse and keep it secure. Server logs are kept for a limited time and then deleted.
• Emails you send us. If you contact us, we receive your email address and whatever you choose to write. We use it only to reply and keep it only as long as needed to handle your message.
• Fonts. The site loads its typefaces from Google Fonts. Your browser connects to Google’s servers to download them, which shares your IP address and browser details with Google. Google’s handling of that data is covered by the Google privacy policy.

We do not ask for your name, address, phone number or payment details, and we do not create profiles of visitors.

Cookies

Visitors to the calculators do not receive advertising or analytics cookies. Our security provider may set a short-lived, strictly necessary cookie to tell real visitors apart from bots. Full details are in our cookie policy.

How We Use Information

• To show you the website and keep it working correctly.
• To protect the site against spam, attacks and misuse.
• To answer messages you send us.
• To meet legal obligations, if any apply.

Where privacy laws such as the GDPR apply, our legal basis is our legitimate interest in running a secure, working website, and, for emails, your request for a reply.

Sharing And Selling

We do not sell or rent personal information, and we do not share it for advertising. Information is handled only by the service providers that run the site for us (web hosting, Cloudflare and Google Fonts), or when the law requires it.

Children’s Privacy

Students of all ages use our calculators. Because the tools need no account and collect no personal information, they can be used without sharing anything about a child. We do not knowingly collect personal information from children under 13. If you believe a child has emailed us personal details, contact us and we will delete them.

Your Rights

Depending on where you live, you may have the right to ask what personal information we hold about you, to correct it, to delete it, or to object to how it is used. As we hold very little, the most common request is deleting an email conversation. Email us and we will respond within the time the law requires.

Security

The site is served over HTTPS, and our providers use industry-standard protection. No system is perfectly secure, which is one reason we keep the data we handle to a minimum.

Other Websites

Some pages link to other websites. We are not responsible for their privacy practices, so please read their policies before sharing information with them.

Changes To This Policy

If we add new features, such as analytics or advertising, we will update this policy before they go live and ask for consent where the law requires it. The date at the top of the page shows when this policy last changed.
