Cookie Policy

Version 2 · last updated 2026-09-03

This page lists every cookie gravam.com sets, plus the things the site keeps in your browser that aren't cookies at all. For how personal data is handled more broadly, see the Privacy Policy.

A cookie is a small text file a website stores in your browser and that your browser sends back on later requests. This site keeps cookies to a minimum and does not use them for advertising.

Essential cookies

Two cookies sit outside the optional analytics choice below:

  • Analytics consent (analytics-consent) — stores the choice you make below so you aren't asked on every visit. Set by this site as soon as you choose; expires after a year.
  • Bot protection (__cf_bm) — set by Cloudflare, which serves this site as a CDN and DDoS filter (see the Privacy Policy). It helps Cloudflare tell automated traffic from real visitors. It is set on every response whether or not you accept analytics, can't be read by JavaScript, and expires about 30 minutes after your last request.

Analytics cookies (optional)

With your consent, the site loads Google Analytics to understand how many people visit and which pages they read. The Google Analytics script is not loaded at all until you accept, and no analytics cookies are set before then. It is never loaded on the unsubscribe or newsletter-confirmation pages — those carry a one-time token in their address, so they stay analytics-free even once you have accepted.

Once loaded, Google Analytics sets its own cookies (names starting _ga). Declining or resetting your choice below stops analytics and deletes those cookies again.

Current choice: Not set yet

In your browser, but not cookies

A few things are kept in your browser's local storage rather than in a cookie. Nothing here is sent to the server on its own — it stays on your device unless you deliberately export or share it:

  • Theme preference (gravam-color-mode) — remembers whether you chose the light or dark mode.
  • Reading progress (read-posts:v1, last-seen:v1, saved-posts:v1, checklist:v1) — which articles you've opened, when you last visited, which ones you saved to come back to, and which boxes you've ticked on the checklist articles. That's what lets a topic page show what you've already read and what's new since, and what keeps a half-finished checklist where you left it.
  • Tool inputs (tool-state:…) — what you enter into the interactive tools, so your figures are still there when you come back.
  • Where an enquiry came from (enquiry-origin:v1) — if you follow a link from a tool, an article or a topic guide toward the contact form, the name of that page is remembered so the enquiry can say where it started. It is a page name and nothing else, it is kept for one browsing session rather than saved to this device, and it is cleared with everything else by the button above.

One exception, and it only happens if you ask for it: a few tools offer a share link. Copying one encodes what you entered into the URL so a colleague can open the same filled-in tool. That URL is a normal web address — it reaches this site's server when it is opened, and if you have accepted analytics it is recorded as the page address. Every tool that offers a share link says so on the page, next to the button. The tools without that button never put your inputs in a URL at all.

Managing cookies in your browser

Clearing this site's data in your browser removes the local storage above along with the cookies. You can also block or delete cookies through your browser settings. Most browsers let you refuse or remove cookies from the "Privacy" or "Help" section. General guidance is available at All About Cookies.

Changes to this policy

This Cookie Policy may be updated if the site's use of cookies changes. The latest version always lives on this page.
