1. What cookies are
Cookies are small text files placed on your device when you visit a website. They serve a range of purposes: keeping you signed in, remembering your preferences, measuring how the site is used, and (for some sites) tracking visitors across properties for advertising. The same definition covers similar technologies like browser localStorage and fingerprinting.
2. The categories we use
- Strictly necessary cookies are required for the site to function. They include security cookies from our hosting provider (Cloudflare) and the cookie that remembers your consent preference. These do not require consent under PECR because the site cannot operate without them.
- Analytics and marketing cookies are set by HubSpot to identify returning visitors, measure traffic sources, and connect form submissions to a CRM record. These require your explicit consent and do not load until you give it.
We do not set advertising cookies (no Google Ads, no Facebook Pixel, no LinkedIn Insight Tag) at the time of writing.

HubSpot's analytics cookies are loaded only after you consent. Cloudflare's security cookies are necessary for the site to operate and are not gated by consent.
4. Your choices
On your first visit you will see a banner offering Accept or Decline for non-essential cookies. You can change your choice at any time using the link below or in the footer of every page. Your choice persists for 12 months, after which we'll ask again.
You can also block or delete cookies directly in your browser. Modern browsers offer per-site cookie controls, and a global "block third-party cookies" toggle is available in all of them. Note that blocking strictly necessary cookies may break parts of the site (the contact form may not submit, for example).
5. Third parties referenced
- HubSpot: analytics, marketing automation and form submission. HubSpot privacy policy.
- Cloudflare: hosting, security, content delivery, and Turnstile bot verification on the Ask page. Cloudflare privacy policy.
- Anthropic: large-language-model provider used by the Ask page. We send your question and the public eCirql reference corpus to the Claude API to generate a reply. We do not send personal information unless you include it in the question. Anthropic privacy policy.
We may add or remove third-party providers over time. Any new cookie added to the site will appear in the table above before it goes live, and the consent banner will re-prompt for material changes.
