GradeCalculator uses a minimal set of cookies for geo-based grading-scale defaults and, when enabled, aggregated analytics or advertising. Calculator grades stay in your browser; we do not store them on our servers.
| Cookie | Purpose | Duration |
|---|---|---|
| gc-geo-scale | Stores detected grading scale from your region | 30 days |
| gc-geo-country | Stores detected country code (ISO) | 30 days |
When enabled, our CDN or analytics partner (for example Cloudflare Web Analytics) may use cookies or similar signals to measure aggregated traffic — not the numbers you enter in calculators.
If we show Google AdSense or other ads, Google and its partners may use cookies to serve and measure ads. You can manage ad personalization in your Google account settings and clear ad-related cookies in your browser.
These keys stay in localStorage, not cookies: theme (gc-theme), grading-scale preference (gc-scale), last calculator used (gc-recent-calculator), and per-calculator inputs (gc-state-*). Clearing site data in your browser removes them.
You can clear cookies in your browser settings. The site will still work with US default grading scales. See our Privacy Policy for more information.
