Privacy
The short version: no accounts, no analytics, no ads, no tracking. Nothing about you is collected, sold or shared.
What stays on your device
A few settings are saved in your own browser (local storage and two small cookies) so the site remembers what you chose. They never leave your device, except the two cookies, which your browser sends back to this site so the page renders in your chosen look. None of them identify you.
| Saved as | What it remembers |
|---|---|
plop-surface, plop-theme (cookies) | The paper and light or dark look you picked on /kit, so the page renders that way from the first paint. |
plop-site-surface | Paper or cutting mat, from the header toggle. |
plop-feedback | Whether haptics and sound are on. |
plop-site-recent | Your last five picks in search, offered as recent searches. |
plop-ride-along-v1, plop-ride-along-hint | Which Ride-along stops you've stamped, and that you've seen the “Not sure where to start?” hint. |
plop-board-v1, plop-lettering-v1 | Your sticker board and lettering in the playground, so they're still there next time. |
To clear them, clear this site's data in your browser settings. Everything still works; it just forgets your picks.
Hosting
The site is hosted on Vercel. Like any web host, Vercel handles each request (which includes your IP address and browser details) to deliver the page and protect the site from abuse. See Vercel's privacy policy. The fonts are served from this site itself, so no request goes to Google or any other font service.
