I made a simple eisenhower matrix to do app with no login required

When I opened it, the matrix itself was the first screen, which suits a no-login tool, and empty-state lines like "Nothing to cut. Nice." make the blank grid feel finished. The question I hit next was "Your tasks never leave your browser": what happens if I clear my browser data or open it on my phone? One line under that saying whether there's an export, or that tasks live on this device only, answers it before someone trusts it with a real list. I'd also add no ads to the "No signup, no labels, no setup." line. I make ThreadFox. Going through your Eisenhower Matrix app as a first-time visitor, I wrote up each thing I hit; the full check is free: https://threadfox.vip/p/eisenhower-matrix… Is staying on one device part of the point, or is sync planned?
