No. It is arithmetic in this browser tab. Nothing is transmitted and nothing persists after you close it.
Because otherwise there is no defined scale to report against. If they total 90%, a perfect performance yields 90, and every figure derived from it is misleading. Rather than silently normalising — which hides a data-entry mistake — the tool reports the total and asks you to fix it.
It uses a common US letter scale with 4.0 points for an A. Institutions vary in their cut-offs, whether they use plus and minus grades, and how they weight credit hours, so treat the figure as indicative and check it against your own handbook.
The target, minus the weighted points already secured, divided by the weight still outstanding. If two assessments remain, the figure is the average needed across both, not on each independently.

Weighted averages and the mistake everyone makes
The most common grade-calculation error is averaging percentages directly: scoring 80% on coursework and 60% on the final does not make 70% unless the two are worth the same. Weighted averaging multiplies each mark by its share of the total, so coursework worth 40% contributes at most 40 points regardless of how well it went. The second common error follows from the first: dividing secured points by 100 rather than by the weight completed. Scoring 80% on the 40% coursework secures 32 points, and reporting that as "32%" to a student halfway through a course is both alarming and meaningless. The honest figure is the average across marked work — 80% — alongside the range of final outcomes still reachable, which is what the best and worst cases are for.
What "what do I need on the final" really tells you
The required-score figure is a simple inversion of the weighted average, and its usefulness depends entirely on reading it correctly. A result of 88% means an average of 88 across everything outstanding, which is a different proposition depending on whether one exam or four assignments remain. A result above 100 does not mean "work very hard"; it means the arithmetic has closed off that grade, and the right response is to recalculate against a lower target. A result at or below zero means the grade is already secured whatever happens next — worth knowing, though not an argument for skipping the exam, since most institutions require a minimum mark on the final regardless of standing.
