Thanks a lot — that really means a lot to me! I’m glad it works well on mobile too. I’m actively working on improving SEO (cleaner landing pages, better descriptions, and more use-case pages). If you have any SEO suggestions or things you think I should prioritize, I’d genuinely love to hear them. Thanks again for the kind words!

Good question. You can actually verify it: after the page loads, you can go fully offline and all features still work. That’s because everything runs locally in the browser, and there are no image uploads. If you check DevTools → Network while editing, you shouldn’t see any file POSTs either.
