Does my data stay local?
Yes. The raw table stays in your browser. Larger saved datasets are encrypted in local browser storage, and the AI layer only receives masked schema and summary statistics.
What can it draw?
It can build histograms, scatter plots with regression, box plots, heatmaps, and time-series views on the same graph canvas.
Can I use it for teaching?
Yes. The same page can switch between direct calculation and explanation, which makes it useful for homework checks and classroom demos.
