Grade Calculator does not collect, store, or transmit student names, grades, or any personal information to a server. Every calculation runs in your browser. The only data saved is your own last-used numbers and settings, kept locally on your device.
What this site does not collect
What's saved on your device, and why
Each calculator remembers your last-used inputs so the numbers are still there if you come back or refresh the page. This is stored using your browser's local storage — a small amount of data kept on your own device, never uploaded anywhere:
| Calculator | What's saved locally |
|---|---|
| Grade calculator | Total questions, wrong answers, point precision, and grading-scale preference |
| Gradebook calculator | Category weights, scores, and preset selection |
| GPA calculator | Course letter grades, credit hours, and course type (regular/honors/AP) |
| Cumulative GPA calculator | Term GPA and credit-hour entries |
None of these fields ask for or store a student's name or any other identifying information — only the numbers needed to reproduce a calculation. This data lives entirely in your browser: we cannot see it, access it, or export it, and it is never transmitted to us or anyone else. You can clear it at any time through your browser's site-data settings.
Standard hosting logs
Like any website, requests to gradecalculators.site pass through our hosting provider, Vercel, which may automatically log basic technical request data (such as IP address, browser type, and requested page) for security and performance monitoring. This is standard infrastructure-level logging that exists independently of anything this site adds — it is not linked to an account, not used for advertising, and not something we query to track individual visitors.
Children's privacy
Because Grade Calculator never asks for or collects personal information from any visitor — including students — there is no separate student data-handling disclosure required beyond what's described above. The site is safe to use in a classroom without creating any student data trail.
Changes to this policy
If what this site stores or how it's hosted ever changes, this page will be updated to reflect it, with the "updated" date at the top revised accordingly.
