Privacy Policy

There are no accounts, and we collect nothing that can identify you. If this service were breached, there would be nothing to take. No name, no contact, no address on our side. What you leave stays on this device.

This site is served through Cloudflare, and Cloudflare injects a visit logging script into our pages by itself. We did not add it, so the browser is instructed to refuse it, and that record never leaves. The tag is still inserted upstream, and it seems better that you know. No cookie is used.

• Your box dimensions, component sizes, names and note stay inside this browser. The layout, the cut plan PDF and the STL files are all built here. There is no upload field, and nothing is sent to any external AI.
• Copying a design link puts the whole design in the URL fragment. Browsers never send that part to a server, so only the person you send the link to can read it.
• The setup timer record is stored on this device only. The clear button, or clearing site data, removes it.
• The server receives anonymous usage signals only: step names (visit, layout made, download, share, PDF download, STL download, card copy, outbound link), UI language, the channel label we wrote into our own link (a short word carried in the link itself, not the browser referrer), and the date you arrived (day only, no clock time). We do not read IP addresses, device info, cookies, or referrers. No dimension is ever sent.
• If you mark interest in a planned paid feature, only its name (one short id we made up) is recorded along with it. It never leads to a sale or payment, and only helps us decide what to build next.
• These signals live in short-term server logs only and are never shared with third parties. To cover running costs we may serve Google AdSense ads, in which case Google may use cookies or advertising identifiers under its own policies.
• Affiliate links to materials appear only when they are configured. Following one takes you to that site, where their own policy applies. We only count that a link was followed.
• Deleting your browser site data removes everything on your side, because no personal record exists on the server.
