Overview
GradeCalculator ("we", "us") respects your privacy. Our calculators process all grade inputs locally in your browser. We do not collect, store, or transmit your grades to our servers.
Information we collect
- Local storage: Optional preferences stored on your device only — theme (gc-theme), grading-scale preference (gc-scale), last calculator used (gc-recent-calculator), and the last inputs for each tool (gc-state-*). We never receive these values.
- Geo cookies: A cookie may store your detected country code to select the appropriate grading scale. No personal information is included.
- Hosting and security: Our site may be delivered through a CDN or security provider (such as Cloudflare). Those services can process standard request metadata (for example IP address and user agent) to protect the site and improve performance. We do not receive your calculator inputs from those logs.
- Analytics: We may use privacy-oriented, aggregated analytics (for example through our CDN) to understand traffic. Those tools do not receive the grades you type into calculators.
- Advertising: If we enable Google AdSense or similar programs, ad partners may set cookies or use similar technologies to show and measure ads. See our Cookie Policy for details and how to manage preferences.
Third parties
We do not sell your data. We do not share grade information with third parties because we never receive it.
