E-E-A-T Trust Center

The E-E-A-T Trust Center is the single page that links every GPACalc trust document: who builds it, how results are calculated and how data is handled.

What is E-E-A-T?

E-E-A-T is a quality framework from Google that evaluates web content on four dimensions: Experience, Expertise, Authoritativeness, and Trustworthiness. Sites that handle sensitive topics like education and personal academic data are held to higher standards.

GPACalc holds itself to that standard because students use these numbers for scholarship applications, graduation targets and university admissions.

Below you will find links to every trust-related page on this site, organized by the E-E-A-T dimension they address. Each page is independently accessible and regularly updated.

Frequently Asked Questions

What is E-E-A-T and why does GPACalc publish this page?
E-E-A-T stands for Experience, Expertise, Authoritativeness, and Trustworthiness. It is a framework Google uses to evaluate content quality. GPACalc publishes this page so users and search engines can verify our credentials, data sources, and editorial standards in one place.

Who is behind GPACalc?
GPACalc is built and maintained by Yida, an independent developer. The project is open-source on GitHub, where anyone can inspect the code, report bugs, or suggest improvements.

How does GPACalc keep calculations right?
School-specific grading data is cross-referenced against official institution publications such as registrar pages and student handbooks. The methodology page documents the exact formulas used, and every school page shows its worked rules next to its sources.

Does GPACalc store any personal data?
No. All GPA calculations run entirely in your browser. No grade inputs are sent to any server, stored in any database, or included in analytics. See the Privacy Policy for full details.
