This Cookie Policy explains how 21 CBI, a service operated by Bitcitizen LLC ("Bitcitizen," "we," "us," or "our"), uses cookies and similar technologies on the 21 CBI website located at 21cbi.io (the "Website").
This Policy works alongside our Privacy Policy and Terms of Service. For matters not addressed here, the Bitcitizen LLC Privacy Policy applies.
The short version, stated plainly: we use a small set of cookies that make the Website work and help us understand which pages get read. We do not run advertising trackers. We do not sell your data. We do not fingerprint you across the web.
A cookie is a small text file placed on your device when you visit a website. Cookies let the site remember information about your visit: authentication state, language preferences, analytics events, and similar functional data. Similar technologies include local storage, session storage, pixels, and server-side identifiers. This Policy applies to all of them.
Cookies are either first-party (set by 21cbi.io directly) or third-party (set by a service we use, such as our authentication provider). We identify the specific third parties involved in Section 5.
We group the cookies we set into three categories. Each is listed with its purpose and the approximate retention period.
These cookies are required for the Website to function. Disabling them will break account sign-in, the advisory dashboard, and certain form submissions. They include:
These cookies help us understand which pages are read, which tools are used, and where sessions exit. We use them to improve the Website, not to build a profile of you personally. Analytics data is aggregated.
These cookies remember preferences that make the Website more useful to you on return visits.
Stating the absence as clearly as the presence. We do not run:
We do not sell, rent, or license cookie data to third parties. We do not use cookies to infer your identity across services outside the Bitcitizen ecosystem.
A limited set of third-party services may set cookies on pages where their functionality is present. Each is listed with the role it serves and a link to its own privacy policy.
We do not embed social media widgets that set cookies on load. External links to X, Instagram, and Nostr open in a new tab and are governed by those platforms’ own policies.
You control cookies in three ways, in order of precision:
Guidance from the major browser vendors:
We respect the Global Privacy Control (GPC) signal. When your browser sends a GPC header, we treat it as a request to limit non-essential cookies and data sharing under applicable privacy laws (including the CCPA and its analogues). We do not currently serve targeted advertising, so there is nothing to opt out of on that front; the GPC signal still suppresses optional analytics where supported.
The legacy "Do Not Track" (DNT) browser signal is not a binding legal standard and is honored inconsistently across the industry. We do not set any advertising or cross-site tracking cookies regardless of DNT state.
We update this Cookie Policy when the cookies we use change, when a third-party service is added or removed, or when applicable law changes. Material updates are reflected in the "Last updated" date at the top of this page. Significant changes will also be announced in the footer or via a site-wide notice for a reasonable period.
Historical versions of this Policy are retained internally and made available to regulators on request.
