Cookies & Tracking — MagicBlocks

Manage your cookie choice.

Re-open the cookie banner to change or withdraw your consent. Works from any page on the site.

1. Overview

This page explains the cookies and similar technologies we use on magicblocks.ai, what they do, who sets them, and how long they last. It is a companion to our Privacy Policy; the Privacy Policy governs personal information generally, and this page is the dedicated reference for cookies specifically.

A cookie is a small text file placed on your device by a website. Similar technologies — local storage, pixel tags, fingerprinting — work the same way in practice and are covered by this notice.

2. Your choice

If you visit from the EU/EEA, UK, or Switzerland, a consent bar appears on your first visit. You can accept all, reject all (other than strictly necessary), or pick categories. Reject is as easy as accept — both are equal-weight buttons. We do not set non-essential cookies before you choose.

If you visit from elsewhere, we do not show a banner because no banner is legally required and we do not want to add friction. You can still re-open the banner at any time via the button on this page (and the footer link on every page) and reject any category you would like to reject.

3. Categories we use

We group cookies into four categories. The first is on by default and cannot be disabled because the site does not function without it. The other three are off by default and only activate if you opt in via the consent banner.

Strictly necessary — form anti-abuse (Cloudflare Turnstile), bot management, and your saved cookie choice itself. Always on.
Functional — remembered preferences (e.g. accepted disclaimers, selected region). Off by default.
Analytics — aggregate, anonymised counts of how the site is used. Helps us see which pages are useful and which are confusing. Off by default. We use our own first-party analytics (Spark), which sets a single anonymous visitor cookie only after you opt in.
Marketing — measurement of advertising campaigns and remarketing to people who have visited the site. Off by default.

4. Cookie inventory

The table below lists every cookie the site sets today. We update it whenever a new tag is wired up. If a category is missing from the table, it means we are not currently running anything in that category — when we do, it will appear here and the consent banner will reappear for returning visitors so they can opt in.

Essential

Name	Purpose	Provider	Duration
`__cf_bm`	Cloudflare bot management — distinguishes humans from automated traffic to keep the site available. Set by Cloudflare edge, not by us.	Cloudflare	30 minutes
`cf_clearance`	Cloudflare challenge clearance — confirms your browser has passed a security challenge so you do not have to re-solve it on every page.	Cloudflare	30 days
`cf_chl_*`	Cloudflare Turnstile — verifies that form submissions are not automated. Required for the contact and demo-request forms.	Cloudflare	Session
`mb_consent`	Stores your cookie-category choices so we do not ask again on every page, plus an anonymous ID used only to record consent events for compliance.	MagicBlocks	12 months

Analytics

Name	Purpose	Provider	Duration
`spark_v`	Anonymous first-party visitor ID so we can count unique visits and see which pages are useful. First-party only — no cross-site tracking, never shared with or sold to third parties. Set only if you opt in to Analytics.	MagicBlocks (Spark)	12 months

This inventory is the canonical reference. If you encounter a cookie not listed here, please email [email protected] — we will investigate and update the table.

5. How we measure traffic

We use a server-side conversion API for marketing attribution. It does not set any cookie on your device and it does not send a tracking pixel from your browser — all measurement happens on our infrastructure based on the standard request information your browser already sends to load the page (URL, referrer, user-agent). Because no tracker fires from your browser, no banner consent is required for this measurement.

We also run our own first-party analytics (Spark) to count visits and see which pages are useful. It sets a single anonymous visitor cookie (spark_v, listed above) and runs only if you opt in to the Analytics category — and only on our main site. It is first-party: the data stays on our infrastructure, there is no cross-site tracking, and it is never shared with or sold to third parties.

6. Browser controls

Most browsers let you block or delete cookies through their settings. Blocking strictly necessary cookies will break parts of the site (for example contact and demo forms). Blocking optional cookies through your browser is equivalent to rejecting them here — we honour both.

7. US privacy rights

If you are a resident of California, Colorado, Connecticut, Utah, Virginia, Texas, or another US state with a comprehensive privacy law, you have the right to opt out of the sale or sharing of personal information and of targeted advertising. We do not sell personal information. If and when we run client-side advertising or remarketing tags, you can opt out by clicking and rejecting the Marketing category, or by using your browser controls.

8. Changes

We may update this notice when we add or remove tools. Material changes will be reflected in the "Last Updated" date at the top of this page. If a new category of cookies is introduced, the consent banner will re-appear for returning visitors so they can review their choice.
