Cookie Policy

The cookies used on nexus.xyz, what each one is for and how to block them.

1. What cookies are

A cookie is a small text file that a website places on your device (computer, phone, tablet) when you visit. Cookies allow a site to remember information about your visit — for example, your preferences, whether you are signed in, or pages you have already viewed. Similar technologies — such as local storage, pixels, tags, and software development kits — perform comparable functions and are covered by this Cookie Policy where the Foundation uses them.

Some cookies are set by the Foundation directly ("first-party"). Others are set by third parties whose technology runs on the Site ("third-party"). See Section 5.

2. Why we use cookies

The Foundation uses cookies and similar technologies to:

  • operate the Site and its core functionality (e.g., remember your sanctions / age gate response, route requests, keep the Site secure);
  • understand how the Site is used (analytics) so the Foundation can improve it;
  • remember your preferences (e.g., region or language); and
  • support marketing measurement and attribution for the Foundation's promotional activity.

Cookies on the Site fall into the following categories:

Strictly necessary. Required for the Site to operate. While browsers allow you to block them, doing so may prevent parts of the Site from working. They include cookies used for security and basic functionality.

Performance and analytics. Help the Foundation measure how the Site is used (which pages are visited, how visitors arrive, where errors occur). This data is generally aggregated and used to improve the Site. Examples of providers: Google Analytics, PostHog.

On the Exchange trading interface, PostHog records masked session replays. All rendered text and all form inputs are masked, so balances, positions, and order sizes are not readable in a replay. Replays are recorded on the trading interface only, and not when your browser sends a Do Not Track signal. The Foundation uses these replays to find where the interface is confusing or broken. When you connect a wallet, PostHog links your analytics events and replays to a pseudonymous account identifier (the SHA-256 digest of your lower-case wallet address), never the address itself; see the public sub-processor list.

Functional. Remember choices you make to give you a more personalized experience (region, language, layout preferences).

If you are signed in on the Exchange trading interface, Intercom sets cookies so that messages and support conversations stay attached to you between visits: intercom-id-<app id> (an identifier that does not expire), intercom-session-<app id> (one week), and intercom-device-id-<app id> (270 days). Intercom is loaded when you sign in, so that the Foundation can send you messages in the product and by email, and so that the support chat is ready when you open it. If you are not signed in, Intercom is not loaded and sets nothing.

Marketing and advertising. Support measurement and attribution of the Foundation's marketing activity, including pixels and tags from advertising platforms. Examples of providers: Meta (Facebook / Instagram), X (Twitter).

4. Third-party cookies

Third parties whose technology may set cookies on the Site include:

  • Google Analytics (web analytics) — see Google's privacy policy and analytics opt-out.
  • Google Tag Manager (tag-loading and event-routing infrastructure used alongside Google Analytics on parts of the Site) — see Google's privacy policy.
  • PostHog (product analytics, error tracking, and masked session replay on the Exchange trading interface) — see PostHog's privacy policy.
  • Intercom (in-product support and messaging on the Exchange trading interface, loaded when you are signed in) — see Intercom's privacy notice.
  • Meta (Facebook / Instagram advertising pixel) — see Meta's privacy policy and ad preferences.
  • X (formerly Twitter — advertising / measurement pixel) — see X's privacy policy.
  • Snag (loyalty / quest Program platform — see Privacy Policy §5) — see Snag's privacy policy.
  • Ghost (blog hosting platform that operates on blog.nexus.xyz) — see Ghost's privacy policy.

Third-party cookies are governed by the privacy practices of the third party setting them. The Foundation does not control how third parties process data collected through their cookies and pixels.

The list above describes third parties known to the Foundation as of the Last Updated date in the header. The Foundation may add, remove, or change third-party cookie providers from time to time.

For details on third-party service providers used by the Foundation more broadly, see the public sub-processor list.

5. How to manage cookies

You can manage cookies through your browser and through the third-party platforms whose cookies are set on the Site.

Browser settings

Most browsers allow you to block, delete, or be notified about cookies. The exact controls vary by browser; see your browser's help documentation. Blocking strictly-necessary cookies through your browser may prevent parts of the Site from working.

Platform opt-outs

For most third-party platforms, opting out is more reliably done through the platform itself rather than through generic cookie controls:

  • Google Analytics opt-out: https://tools.google.com/dlpage/gaoptout
  • PostHog: PostHog does not publish a consumer opt-out page. Blocking cookies for nexus.xyz and its subdomains in your browser — the Exchange trading interface is served from app.nexus.xyz — or using a tracker-blocking browser extension, prevents PostHog analytics from collecting. See PostHog's privacy policy.
  • Intercom: Intercom does not publish a consumer opt-out page. Intercom is loaded only for signed-in users of the Exchange trading interface, so using the Site without signing in prevents Intercom from loading and from setting any cookie. Signing out ends the Intercom session. Blocking cookies for nexus.xyz and its subdomains in your browser, or using a tracker-blocking browser extension, also stops Intercom from setting cookies. See Intercom's privacy notice.
  • Meta ad preferences: https://www.facebook.com/adpreferences
  • X / Twitter privacy controls: https://x.com/settings/privacy_and_safety
  • Network Advertising Initiative (industry-wide ad-network opt-out): https://optout.networkadvertising.org/
  • Digital Advertising Alliance (industry-wide ad-network opt-out): https://optout.aboutads.info/

The Foundation may update this Cookie Policy from time to time, including to reflect changes in the cookies in use, the deployment of a consent-management platform, or applicable law. Updates will be posted at https://nexus.xyz/cookie-policy and the "Last Updated" date in the header will be updated. Continued use of the Site after an update takes effect constitutes acceptance of the updated Cookie Policy.
