This Cookie Policy explains how Block Zero (the “Service”) uses cookies and similar technologies. It pairs with Section 6 of our Privacy Policy.
1. What cookies are
Cookies are small text files placed on your device when you visit a website. Similar technologies — such as pixels and local storage — work in comparable ways. We refer to all of these as “cookies” in this policy.
2. How we use cookies
We use cookies to keep you signed in and secure your session, to remember a few choices you make on your own device, and — only with your consent — to understand how the Service is used so we can improve it. Some cookies are strictly necessary for the Service to function; some only remember a choice you make on this device (such as your color theme); the rest are optional and set only after you opt in. Where consent is required, our legal basis is your consent under Article 6(1)(a) of the GDPR and Section 25 of the German Telecommunications Digital Services Data Protection Act (TDDDG).
3. Categories of cookies we use
| Category | Purpose | Consent needed? |
|---|---|---|
| Strictly necessary | Keeps you signed in, secures your session, and remembers your cookie choice. The Service can’t function without it. | No — required to operate |
| Preferences you set | Remembers choices you make on this device so we don’t ask again — your light or dark theme, and that you checked the Terms box on the sign-in form or at checkout. Kept in your browser’s local storage and never sent to us. | No — stored only because of your own action |
| Analytics | Google Analytics, used to understand aggregated usage (such as which pages are viewed) so we can improve the course. Set only if you accept. | Yes — off until you opt in |
We do not use advertising or marketing cookies, and we do not sell your personal information.
4. Managing your choices
When you first visit, we ask for your consent before setting any non-essential (analytics) cookies — you can accept or reject them, and rejecting is as easy as accepting. You can change or withdraw your choice at any time:
You can also control cookies and local storage through your browser settings, including deleting what has already been stored. Blocking the strictly necessary cookies may stop parts of the Service — such as signing in — from working.
5. Changes and contact
We may update this Cookie Policy from time to time; the “Last updated” date above shows when. Questions can be sent to info@cwm-digitaltech.com. Our full legal-identity details are in our Imprint.
