Your photos and charts
Photos you choose, drop or paste are read by your own browser, and the chart, PDF and PNG are made on your device. Nothing is uploaded to us.
Your current chart and stitched marks are saved in your browser's own storage on your device, so they are there when you come back. Clearing your browser data removes them. Progress files you save stay wherever you put them.
What we collect
Nothing. No accounts, no tracking cookies, no analytics. The site is served by Cloudflare, which keeps standard short lived server logs to run and protect it, and fonts load from Google Fonts. If this ever changes, this page will say so first.
