Notice · On cookies

What we store. What we don't.

What we store. What we don't. We use only essential cookies needed for authentication, session management, and security. We do not use analytics, marketing, or third-party tracking cookies. There is no cookie banner because, under UK PECR, strictly necessary cookies are exempt from consent requirements. If we ever change that, we will tell you before we do.

§ 1 · What cookies are

Text files. Some essential.

Cookies are small text files stored on your device when you visit a website. They let a site remember who you are between pages, keep you signed in, and help detect abuse. Some cookies are essential for the service to function; others are optional and used for measurement or marketing. NEXUS · DSP uses only the first kind.

We also use comparable browser-storage technologies (including localStorage) to remember your in-session preferences. For brevity we refer to these collectively as "cookies" in this notice.

§ 2 · Cookies we set

Two categories. Both necessary.

2.1  Strictly necessary

Required for the platform to function. Cannot be disabled without breaking core functionality.

CookieProviderPurposeDuration
sb-*-auth-tokenSupabaseAuthentication session — keeps you signed in30 days (rolling)
__cf_bmCloudflareBot detection30 minutes

2.2  Functional

Stored on your device to remember your preferences. Not personal data.

2.3  What we do not use

  • Analytics cookies (Google Analytics, Plausible, Mixpanel, or similar)
  • Advertising or marketing cookies
  • Social media cookies or share-button tracking
  • Session-replay or heat-map cookies
  • Third-party tracking cookies of any kind

If this changes in future, we will update this notice, update our platform to require consent before any such cookie is set, and display a cookie consent banner to comply with UK PECR.

§ 3 · Third parties that may set cookies

Three providers. Narrow scope.

ProviderWhenWhat forTheir policy
CloudflareEvery pageDDoS protection, bot detectioncloudflare.com/privacypolicy
SupabaseAfter sign-inAuth sessionsupabase.com/privacy
StripeBilling / checkout pages onlyPayment fraud preventionstripe.com/privacy

We do not permit these third parties to use cookies for any purpose other than the service they provide to us.

§ 4 · Why we don't show a cookie banner

PECR says we don't have to.

Under the UK Privacy and Electronic Communications Regulations 2003 (as amended) and the ICO's guidance, cookies that are strictly necessary for a service requested by the user, or that store user preferences within a session, are exempt from the consent requirement. All cookies set by NEXUS · DSP fall into one of these exempt categories. We therefore do not display a consent banner.

We take this position intentionally. Banners that pester visitors to accept unnecessary cookies are an artefact of advertising-driven platforms. NEXUS · DSP is not one of those.

§ 5 · Managing cookies in your browser

Your browser, your controls.

You can control or delete cookies through your browser settings. Note that disabling strictly-necessary cookies will prevent you from signing in to the platform.

§ 6 · Changes

If we change anything, you'll see it here.

We may update this notice from time to time. The "Last revised" date at the top of this page reflects the most recent change. If we change our cookie practices — for example, by introducing analytics — we will update this notice and, where required, request your consent before the change takes effect.
