No accounts, no tracking

Part 3 Partner is free and has no sign-up, no accounts and no payments. It does not use advertising or analytics cookies, and it does not track you across other sites.

Visitor statistics

To see how many people use the site, it uses Cloudflare Web Analytics. This counts page views and records general information such as the country a visit comes from, the type of device and browser, and the site that linked to the page. It does not use cookies or local storage, does not create a profile of you, and does not track you across other sites. We only see totals, not individual visitors. See Cloudflare Web Analytics for details.

What stays in your browser

A few settings are saved in your browser's local storage so they are still there next time: your light or dark theme choice, and diagram editor preferences: panel sizes, custom colour palettes, your swatch charts, your 12 most recent colours, the colour picker tab you last used, and any text styles you save to your style library to reuse in other diagrams. This data stays on your device. It is not sent to us, and it is not shared across devices.

The diagram editor also keeps a draft of each diagram you edit, so your work is still there if you close the tab: the edited diagram, its layers, text styles and palette, when it was saved, and a list of which diagrams have drafts. You can restore or discard a draft when you reopen the diagram, and clear all drafts from the editor's Project menu. Drafts are deleted if you undo back to the original diagram.

Clearing your browser data, or using a private window, will remove these settings and drafts. Drafts stay in this browser only, so use the editor's Export project or Download SVG to keep a copy or move your work to another device.

Fonts in the diagram editor

The site's own font is served from this site. The diagram editor's font picker loads extra fonts from Google Fonts, which means your browser contacts Google when you use it. Diagrams you download from the editor also reference Google Fonts, so opening an exported SVG in a web browser may contact Google too.

Hosting

Like any website, the hosting provider may keep standard server logs, such as IP address, browser type and the pages requested, for security and reliability. These logs are not used to identify you.
