All calculator math runs in your browser — we never see your inputs.
We use analytics to understand how the site is used, not to identify you.
We never sell your personal data.
Contact form submissions are stored securely and used only to reply to you.
1. Who We Are
GeneralCalc ("we", "us", "our") operates the website at generalcalc.com. We provide free online calculator tools for personal and educational use. For privacy-related inquiries, contact us at our contact page.
2. Information We Collect
Information you give us: When you submit the contact form we collect your name, email address, the subject of your message, and the message text. We also log your IP address for spam prevention.
Information collected automatically: Like most websites, our servers record standard access logs (IP address, browser type, pages visited, timestamps). We may use a third-party analytics service (e.g., Google Analytics) that sets cookies to measure traffic patterns. These analytics are aggregated and do not identify you personally.
Calculator inputs: All calculation logic runs entirely in your browser using JavaScript. Your calculator inputs are never transmitted to our servers.
3. How We Use Your Information
We use the information we collect to:
Respond to your contact form submissions
Fix bugs and improve calculator accuracy
Understand which calculators are most useful
Protect the site from spam and abuse
Comply with legal obligations
4. Cookies
We use the following types of cookies:
Strictly necessary: Session and CSRF cookies required for the contact form to work securely.
Analytics: Optional analytics cookies (e.g., from Google Analytics) that help us understand site traffic. You can opt out via your browser settings or using browser extensions like uBlock Origin.
We do not use advertising or tracking cookies. We do not participate in cross-site behavioural advertising.
5. Sharing Your Information
We do not sell, trade, or rent your personal information. We may share data with:
Service providers who help us operate the site (e.g., hosting, analytics) under strict data-processing agreements
Law enforcement when required by law or to protect our legal rights
6. Data Security
Contact form submissions are stored in an encrypted database. We use HTTPS across the entire site. Passwords (for future user accounts) will be hashed using bcrypt. No system is perfectly secure, but we take reasonable technical measures to protect your data.
7. Data Retention
Contact form messages are retained for up to 2 years or until you request deletion. Server access logs are retained for 90 days. Analytics data is retained per the third-party provider's policy (Google Analytics default: 14 months).
8. Your Rights
Depending on your jurisdiction, you may have the right to:
Access the personal data we hold about you
Request correction of inaccurate data
Request deletion of your data ("right to be forgotten")
Withdraw consent at any time where processing is based on consent
To exercise any of these rights, contact us through our contact form.
9. Children's Privacy
Our site is not directed at children under 13. We do not knowingly collect personal information from children. If you believe a child has submitted information to us, please contact us immediately and we will delete it promptly.
