What happens to your data

• Everything is calculated in your browser. Your fabric settings, pieces, notes and layouts aren't sent to us or to anyone else. Our automated tests log every network request the planner makes and check that none of them carries your data.
• Autosave: your current project is saved in your browser's localStorage on this device so it survives a reload. Use Start over, or clear this site's data in your browser settings, to remove it. The width comparison page reads the same saved project only when you click "Use my planner project".
• Project files (bolt-and-grain-project-….json), PDFs and SVGs are created on your device and downloaded straight to it. Opening a project file reads it locally, and invalid or unexpected content is discarded.
• Error log: if a script error happens, a short technical message (time, page path, error text) is kept in localStorage, capped at 20 entries. It is never transmitted.
• No accounts, no advertising, no analytics and no tracking cookies are used on this site at present.

Hosting

The site is hosted on Cloudflare Pages. As with any website, Cloudflare processes technical request data such as IP addresses to deliver pages and protect against abuse, under its privacy policy. We don't receive personal visitor logs from it.

Future changes

If we add advertising, analytics or affiliate links, this page will be updated before they go live, along with any consent prompt the law requires where you live.
