Privacy Policy

Last updated 16 October 2026

Your data stays in your browser

This site has no database. Charts are drawn in your browser and the numbers you type aren't sent to us. Downloads (PNG and SVG) are made on your device. When you use Copy share link, your chart's title, labels, values and settings are encoded into the web address after ?d=. Web addresses are sent with page requests, so that data is visible to our server (which does not keep it), to Cloudflare's ordinary short-term logs, to analytics if enabled, and to anyone you send the link to. It is encoded, not encrypted. Don't share a link to a chart containing data you want kept private.

Clipboard

The share link and caption buttons write to your clipboard when you press them. Pasting into the table reads only what you paste. The site never reads your clipboard on its own.

Fonts

Headings use the Fraunces typeface, loaded from Google Fonts, so your browser requests it from Google's servers.

Analytics and advertising

We use Google Analytics to see which pages are visited, in aggregate. We may show ads through an advertising network; if we do, this page will name it and link to its disclosures and opt-outs before ads appear.

What we do not do

No accounts, no cookies of our own, no email collection, no saved charts, and we do not sell personal information. Questions or requests: p@pwhite.org.
