Privacy
What this site handles, and what it does not. Last updated:
What you type, and what you make
Part numbers, headings, descriptions, notes, the finished diagram — none of it is sent to a server. Typing, layout and export all happen inside your browser, and the person running this site cannot see any of it.
Saving happens in the browser too, in IndexedDB. It is confined to that device and that browser, so you cannot pick the work up on another machine; to move it, export the JSON and carry the file. Clearing this site's data in your browser settings deletes the saved work with it.
What is stored in your browser
| What | Where | Why |
|---|---|---|
| The diagrams you make (part number, items, notes, font settings) | IndexedDB | So the work is still there next time you open the tool |
| Copies of the site's files for offline use | Service Worker cache | So the tool opens without a connection |
| Your choice of width for the navigation on the left (full or collapsed): one word (expanded or rail), kept only if you press the navigation's Collapse / Expand button | localStorage | So the navigation is the width you chose next time |
None of it is used for tracking.
Analytics and advertising
This site uses Cloudflare Web Analytics (since 17 September 2026). There is no advertising.
By Cloudflare's own description, this analytics uses no cookies and no localStorage, and does not fingerprint anyone by IP address, user agent or anything else. What your browser sends to Cloudflare is the URL of the page you are on, the URL you came from (the referrer), and timing figures for how the page loaded. What this site can see is aggregate counts per page — views, referrers, countries, device types, load times — and not who was there.
No consent is asked for. A measurement that stores nothing in your browser and identifies nobody has no information to consent to. Instead, if your browser sends a Global Privacy Control signal, this analytics is not loaded at all. The page itself decides whether to load it — it is not injected by Cloudflare — which is what makes the signal possible to honour.
This site used to show a cookie banner asking, in advance, about "analytics" and "advertising". With nothing to consent to, that served this site rather than the people reading it, so it was taken down on 17 September 2026.
If anything that stores information in your browser or identifies you — advertising, for instance — is introduced later, this page will be updated first and consent will be asked for then: consent given before there is anything to consent to is not specific enough to be worth anything.
Records on the server side
The site is served by Cloudflare. While delivering pages and files, Cloudflare may record connection details — IP address, timestamp, requested URL, user agent and the like. Those are operational and security records of the hosting platform, and the operator does not use them to identify or track anyone. The part numbers you type and the diagrams you make are not in those records — they are never sent.
Outbound connections
This site loads no third-party scripts and no external font service; the fonts are served from this site. The exception is when you follow a link to an external site such as GitHub, where that site's own policy applies.
Use by children
No age restriction applies: nothing here asks for personal information.
Changes to this policy
Any change is accompanied by a new date at the top of this page. If a change means storing information in your browser or identifying you — introducing advertising, for instance — consent will be asked for then.
