Privacy Policy
Last Updated: September 2026
1. Introduction
At Grade Percentage Calculator (accessible from gradepercentagecalculator.com), your privacy is one of our top priorities. This Privacy Policy document outlines what types of information we do and do not collect and how we protect your academic integrity.
2. Zero Academic Data Collection
We do not collect, store, transmit, or monetize your grade information. All calculations—including scores entered, total points possible, custom percentage thresholds, and calculated percentages—are processed entirely on your device via client-side JavaScript in your browser.
When you close your browser or reset the calculator, no record of your scores remains on our infrastructure.
3. Web Hosting & Technical Server Logs
Like most standard website hosting providers, our static hosting platform may automatically record standard web server log entries when you request pages. These logs typically include IP addresses, browser types, Internet Service Providers (ISP), referring/exit pages, date/time stamps, and visit duration. These records are not linked to any personally identifiable information and are strictly used for DDoS protection, infrastructure health monitoring, and system optimization.
4. Cookies and Web Storage
Grade Percentage Calculator does not use persistent tracking cookies or user fingerprinting. If you customize your grade scale, those preferences may be held temporarily in your browser session or URL query parameters solely for your own convenience.
5. Advertising & Third-Party Services
In the future, third-party advertising partners may serve non-personalized advertisements on informational sections of our website to support hosting costs. Third-party vendors may use cookies to serve ads based on prior visits to this or other websites. You may opt out of personalized advertising by visiting Google Ads Settings or www.aboutads.info.
6. Children's Privacy
We are committed to protecting the privacy of minors using our academic utilities. Grade Percentage Calculator does not knowingly collect any personally identifiable information from children under the age of 13. Because our service operates without accounts or personal data input, no child's personal data is ever recorded.
7. Updates to This Policy
We may update our Privacy Policy periodically. We encourage you to review this page occasionally for any revisions. Any changes become effective immediately upon posting to this page.
