Cookies Policy

This Cookies Policy explains how BigDataCyberCloud.com uses cookies and similar technologies — the essential, analytics, and functionality categories — and how you can review and change your preferences at any time.

Last updated: 6 October 2026

What Are Cookies?

Cookies are small text files placed on your device when you visit a website. They help a site work, remember your choices, and — with your permission — understand how it is used. Similar technologies, such as your browser’s local storage, work in much the same way and are covered by this policy too.

Types of Cookies We Use

Essential cookies

These are necessary for the Site to function and to keep it secure. They don’t track you across other websites and can’t be switched off on our side.

setup-complete

Purpose: Records that first-run setup is complete, so the admin area doesn’t redirect to the install wizard

Duration: 1 year

Set by: this Site

next-auth.session-token, next-auth.csrf-token

Purpose: Signed-in session and login protection for the /admin area — only set for administrators who log in

Duration: Session, or up to 30 days

Set by: this Site (NextAuth.js)

__cf_bm, cf_clearance

Purpose: Bot and abuse protection — set only when Cloudflare needs to check that traffic is coming from a real browser

Duration: 30 minutes to 1 year

Set by: Cloudflare, on this domain

Analytics and performance cookies

These help us understand which guides are read and how visitors find them, so we can improve the Site. They are set only if you click “Accept analytics” on the cookie banner.

_ga, _ga_<container-id>

Purpose: Google Analytics 4 — pseudonymous visitor and session counts, pages viewed, referral source, country-level location

Duration: Up to 2 years

Set by: Google Analytics (third party), only with your consent

Until you choose (or if you decline), Google Analytics runs in Google Consent Mode: it sets no cookies and receives only an anonymous, cookieless signal that a page was viewed, which Google uses for aggregate modelling. Cloudflare Web Analytics also counts visits in aggregate without using cookies.

Functionality

We remember your cookie choice so the banner doesn’t reappear on every page. This is stored in your browser’s local storage (key bdcc-consent), not in a cookie, and stays until you change your choice or clear your browser data.

Marketing and advertising cookies

We don’t use any. The Site sets no advertising, retargeting, or social-media tracking cookies, and we don’t build advertising profiles.

Third-Party Services

The following providers may set or read cookies, or process data, when you use the Site:

  • Google Tag Manager — loads our analytics configuration
  • Google Analytics — measures site traffic and usage, cookies only with your consent
  • Microsoft Bookings — our meeting scheduler; its cookies apply only on Microsoft’s booking page when you open it
  • Cloudflare — delivers and protects the Site; may set security cookies and provides cookieless analytics

Managing Your Cookie Preferences

Cookie consent banner

On your first visit, a banner lets you accept or decline analytics cookies. You can change your choice at any time with the button, which is also in the footer of every page. If you decline, any Google Analytics cookies already set are removed.

Browser settings

Most browsers let you block or delete cookies:

  • Google Chrome: Settings → Privacy and security → Third-party cookies / Delete browsing data
  • Mozilla Firefox: Settings → Privacy & Security → Cookies and Site Data
  • Safari: Settings → Privacy → Manage Website Data
  • Microsoft Edge: Settings → Privacy, search, and services → Cookies and site data

Please note: blocking essential cookies won’t affect reading the guides, but it will stop the admin area from working.

Do Not Track Signals

Some browsers send a “Do Not Track” (DNT) signal. There is no agreed standard for responding to it, so the Site does not change its behaviour based on DNT; you can control analytics through the cookie banner and your browser settings instead.

How Long Do Cookies Last?

  • Session cookies are temporary and are deleted when you close your browser.
  • Persistent cookies remain until they expire or you delete them — the duration for each cookie is listed above.

Updates to This Cookies Policy

We may update this policy to reflect changes in the cookies we use or in legal requirements. If we add a cookie that needs your consent, we’ll ask for your consent again.
