Last updated: August 20, 2026

At Percent Off Calculator (accessible at percentoffcalc.com), we respect your personal privacy. This Privacy Policy explains what information is collected when you use our website, how that data is used, and how we protect your rights.

1. 100% Client-Side Calculation Privacy

All financial calculations, product prices, discount percentages, tax figures, and salary numbers entered into our online calculators are processed entirely within your web browser using local JavaScript runtime memory.

We do not transmit, log, store, or monitor any calculation inputs or numerical entries on our servers.

2. Information We Collect

  • Voluntarily Submitted Information: If you contact us through our Contact Us form or via direct email, we collect your name, email address, and message contents solely to respond to your inquiry. We never sell, rent, or trade your contact details with third-party marketers.
  • Automated Server Log Files: Like standard web platforms, our servers automatically log non-identifying technical data when you visit (such as IP addresses, browser types, operating systems, referring URLs, date/time stamps, and page response times) to maintain website security, prevent abuse, and monitor server uptime.

3. Cookies, Web Storage & Advertising Disclosures

We use browser storage technologies to provide a smooth user experience. For comprehensive details on all cookies and storage mechanisms, please review our dedicated Cookies Policy.
