CHARTFUL
Privacy: the Chartful browser extension
The extension keeps prop-firm websites closed while the Chartful app on your Mac says purchases are locked.
It asks the Chartful app on the same Mac which firm sites to close. That conversation stays on your computer.
It doesn't collect, store or send anything: not your browsing, not the pages you visit, not what you type. It has no account, no analytics and no tracking, and it loads no code from the internet.
It only has access to the prop-firm sites on Chartful's list, so it can show its "locked" page there. It doesn't read those pages.
On TopstepX it also blocks the platform's own Reset purchase. To do that it looks at the text of pop-ups on TopstepX and covers the ones offering a reset. That check happens in your browser; it keeps and sends nothing.
