Your course scores are calculated in your browser. No school login or student name is needed.
Visits and tool actions
The public site uses Plausible Analytics and Google Analytics 4 to record visits and basic actions such as calculating or copying an answer. Calculator entries, scores, course names and imported lists are not sent to analytics.
Analytics are disabled on local previews. The site does not add grades to page addresses or analytics events.
Plausible counts every visit without cookies. It may receive browser and device information and a referring page.
Google Analytics is run by Google, which receives the page address, the actions we measure on this site and browser and device information, and sets cookies that tell repeat visits apart. Its advertising features are off.
In the European Union, Iceland, Liechtenstein, Norway, the United Kingdom and Switzerland, and whenever we cannot tell which country a visit comes from, Google Analytics loads only after you choose Accept on the bar at the bottom of the page. Decline loads nothing from Google. Your choice is kept in this browser for six months, then the bar asks again.
Elsewhere, Google Analytics loads with each page unless you choose Decline. Cloudflare, which delivers our pages, tells your browser which country the visit comes from.
Wherever you are, Cookie choices at the bottom of any page, or the button below, changes your choice. Decline stops Google Analytics on this site in this browser and deletes its analytics cookies. If analytics was running, the page reloads to apply your choice. Decline holds on every page; outside the countries above it is kept until you change it.
Scores, saved settings and storage
Calculator entries live in the open page. Choosing a connected tool puts only the needed values in session storage in this tab. The receiving tool uses and removes that handoff. Closing the tab clears it.
Settings you change are kept in this browser's local storage so they are ready on your next visit: the letter-grade scale, your cutoffs, the rounding rule, decimal places, your school's grade points and extra-point rules, semester weights and the easy grader's question count. Scores and courses are kept only when you tick “Keep my scores” or “Keep my courses”. Nothing kept this way is sent to this site or to analytics.
“Forget saved settings” beside a calculator removes everything this site keeps in your browser, apart from your theme and cookie choices. Clearing this site's data in your browser settings removes that too.
A CSV download is created in your browser and saved wherever you choose. Copying a result puts that text on your clipboard. Hosting services may record request paths, IP addresses and browser information when serving pages.
Your light or dark theme choice is saved in this browser so it stays the same on your next visit. This preference contains no grades.
Fonts and other websites
Fonts are served with this site. When Google Analytics loads, it makes requests to Google as described above. Links to school policies open their own websites, whose privacy practices apply.
Contact information
The contact form sends your report, your reply address and any page or source you add through Cloudflare, which runs an automatic security check that never asks you to solve anything. We keep each report in our contact inbox at Cloudflare for 12 months, then it is deleted automatically, and a copy goes to a private Discord channel our team reads. We use your reply address only to answer you. To see or delete a report you sent, use the same form and we will delete both copies. Please do not include passwords, keys or private documents.
