Cookies are small text files that a website stores on your device. They can be set by the site you're visiting ("first-party") or by other services embedded on that site ("third-party").
HelixSource does not currently set tracking, analytics, or advertising cookies. The only client-side storage we use is for the strictly-necessary purposes described below.

Session storage (strictly necessary) | Remembers that you have acknowledged the research-use-only notice so it does not appear again during your visit. | Cleared when you close the browser tab. |
| Cloudflare security cookies | Strictly necessary (first-party) | Used by our hosting provider to detect malicious traffic and protect the Site. | Up to 30 days. See Cloudflare cookie policy. |
When you submit the contact form, the request is sent to Formspree (our form processor). Formspree may set its own cookies during that round-trip purely to handle the submission. We do not control these.
You can clear or block cookies and site storage in your browser settings. Doing so should not affect any core functionality of this Site, although the RUO notice will reappear on every visit.
If we add new cookies (for example by introducing analytics) we will update this notice and, where required, show a consent banner before any non-essential cookies are set.
