Privacy Policy
How this website handles your data. The short answer: no tracking, no ads, and an account only if you choose to log in with Patreon.
Last updated: 13 November 2026
The short version. This is a static website. It runs no analytics scripts, shows no ads and embeds no third-party widgets. Browsing it sets no cookies and needs no account.
Anything else is stored in your own browser, and only once you make a choice: your theme and other preferences, your 3D viewer settings, any map markers you place. It never leaves your device, and you can see and clear all of it on the settings page, with or without an account. Our hosting provider keeps short-lived server logs, as every web host does.
Logging in with Patreon is optional and only needed for member downloads. If you do, we store your Patreon ID and your membership tier, and cookies keep you logged in. Your Patreon username and picture are shown to you from a cookie in your own browser and are not stored by us. No email, no full name. Section 8 has the detail.
1. Scope and who is responsible
This policy covers this website wherever it is served from, including any domain or subdomain it runs under and the separate origin that serves its images and map tiles.
The site is operated by McMeddon, who is the controller for any personal data processed through it under the EU General Data Protection Regulation (GDPR).
For privacy questions or to exercise any of the rights in section 9, contact us through the Discord ticket channel.
2. Server logs
The site and its map tiles are served by Cloudflare (Workers and R2 storage). When your browser requests a page or a tile, Cloudflare processes the usual connection data: your IP address, the requested URL, the time of the request, your browser's user agent string and the referring page.
That data is used only to deliver the files you asked for, to keep the service available and to defend it against abuse. The legal basis is our legitimate interest in operating a working, secure website (Art. 6(1)(f) GDPR). Logs are short-lived, are not linked to any profile and are never used to build one. Cloudflare also aggregates this log data into the traffic statistics we see in its dashboard, described in section 5.
Cloudflare acts as our processor and may process this data on servers outside the EEA under the European Commission's Standard Contractual Clauses. See the Cloudflare Privacy Policy.
3. Cookies
Browsing this site sets no cookies. Not for analytics, not for advertising, not for anything else.
Cookies are only set if you choose to log in with Patreon (section 8), and only the ones that login needs:
| Cookie | What it is for | Lifetime |
|---|---|---|
__Host-mcm_session | Keeps you logged in. A random value that only this site's server can read; scripts on the page cannot. | 30 days, or until you log out |
mcm_in | Tells the pages that you are logged in, so they only ask the server about your membership when there is one. Holds the value 1 and nothing about you. | 30 days, or until you log out |
__Host-mcm_profile | Your Patreon username (or first name) and the address of your Patreon profile picture, so the account page can greet you. Kept in your browser only: it is not stored on our side. Scripts on the page cannot read it. | 30 days, or until you log out |
__Host-mcm_oauth | Ties the answer from Patreon to the browser that started the login, so nobody else can finish it. | 10 minutes, removed as soon as the login completes |
These belong to a service you asked for, the member login and its account page, so no consent is required for them (Section 25(2) TDDDG). They are never used to track you across pages or sites.
Why there is no cookie banner. Consent is needed for anything a site stores on or reads from your device that is not strictly necessary for a service you asked for. Here, nothing falls into that group: the cookies above exist only for the login you chose, and the entries in section 4 are written only when you use the control they belong to, to remember that very choice. There are no analytics, advertising or third-party scripts that would need your consent. If that ever changes, you will be asked first (section 10).
4. What is stored in your browser
The site remembers a handful of choices in your browser's local storage (kept until you clear it) and, for a few, its session storage (forgotten when you close the tab). Each entry is written only when you use the control in question, it stays on your device, and it is never sent to us or to anyone else. None of them identify you.
Site preferences
| Key | What it holds | Written when |
|---|---|---|
theme | Light or dark theme. | You switch the theme |
pref:motion | That you turned off autoplay and animations. | You turn it on in settings |
pref:sidebar | Whether the sidebar on wide screens shows icons only or the full list. | You press ☰ or choose it in settings |
sb-fold:<section> | Which sidebar sections you opened. Session storage: gone when the tab closes. | You open or close a section |
3D explorer, maps and tools
| Key | What it holds | Written when |
|---|---|---|
mc-coords-on | Whether the coordinate readout is shown. | You toggle it |
vw-coords-style | Which coordinate readout style you prefer. | You switch it |
vw-chrome-hidden | Whether you hid the viewer's on-screen controls. | You hide or show them |
vw-blocky-shadows | Your terrain shadow setting. | You change it |
poi-visible | Whether point-of-interest markers are shown. | You toggle markers or place one |
poi-user:<world> | Map markers you placed yourself on a given world, with the name you gave them. | You place or remove a marker |
nbt-doctor-rules | Which checks you ticked in the NBT Doctor tool. | You change the ticks |
Only if you are logged in
| Key | What it holds | Written when |
|---|---|---|
pref:download-host | Google Drive or Proton Drive, whichever you want listed first for member downloads. | You choose it in settings |
member:me | Your tier, your Patreon username and the address of your picture, as the server last confirmed them, so pages show who is logged in straight away and do not have to ask the server on every page. A copy of what the page already shows; it is not sent anywhere. Removed when you log out. | A page checks your login |
pref:last-visit | When you last opened your account dashboard, so it can point out worlds and posts added since. A per-tab copy (pref:last-visit-base, session storage) keeps the highlight while you reload. | You open the dashboard |
You can delete every entry above at once with Clear local data on the settings page, which needs no account, or by clearing site data for this domain in your browser. Either resets your preferences and removes any markers you saved. Clearing local data does not log you out: the login cookies in section 3 end when you log out.
Your browser also caches pages, map tiles and images so that flying around a world does not re-download the same data. That is ordinary browser caching and you can clear it the same way.
5. No tracking or profiling
We do not use Google Analytics or any comparable product, we run no advertising or affiliate scripts, we load no tracking pixels, and we serve our fonts from this domain rather than a font CDN. Nothing in the page reports back on what you do while you are on it, and no profile of your visit is created anywhere.
Cloudflare does produce aggregate traffic statistics (request counts, rough country totals, error rates) from the server logs described in section 2. Those are counts, not people: they come from data Cloudflare already handles in order to serve the site, they involve no script in your browser and no storage on your device, and they cannot be traced back to an individual visitor by us.
6. Links to other sites
We link out to third-party platforms such as YouTube, Patreon, Discord and PlanetMinecraft. These are plain links: nothing is embedded, so those services receive no data about you until you actually click through. Once you do, their own privacy policies apply and we have no control over what they collect.
7. Commissions and correspondence
There is no contact form on this site. If you get in touch about a commission you do so through Discord, Patreon or PlanetMinecraft, and your data on those platforms is governed by their policies.
Where we then correspond about an actual project, we keep that correspondence and the project details for as long as needed to carry out and document the agreement (Art. 6(1)(b) GDPR), plus any period required by tax or commercial law.
8. Member login with Patreon
Logging in is optional. It exists so that Patreon members can download the worlds their membership includes directly from this site. If you never log in, nothing in this section applies to you.
When you press "Log in with Patreon" you are sent to Patreon, which asks you to confirm. Patreon then tells us: your Patreon user ID, your membership of our Patreon page (whether you are a member, and at which tier), your Patreon username or, if you have none, your first name, and the address of your profile picture. We ask Patreon for nothing else. In particular we do not request your full name, your email address or your connected accounts, and we receive no payment details.
Patreon's confirmation screen describes the permission as "identity info, including full name, account status, and connected social accounts". That is Patreon's wording for the smallest permission it offers, and it describes what the permission would allow, not what we ask for.
The username and the picture are only there to greet you on the account page. They are not written to our database: at login they are placed in a cookie in your own browser (section 3), and the account page shows them from there. The picture itself is fetched from Patreon by our server and passed on to you, so your browser makes no request to Patreon for it.
What we store, and nothing more:
- your Patreon user ID and the ID of your membership of our page,
- when your account here was created,
- the tier that membership gives you here, when it was last checked and until when that check is trusted,
- for each login, a one-way hash of your session cookie with its start and end date,
- how many member downloads you started today: a single number, which keeps any one account from copying the whole library at once. It is deleted the next day.
- which worlds you have downloaded here: for each world and file (the world or its source files), when you first and last downloaded it and how many times. This is what lists your downloads on your account page on any device. It holds no download links and nothing about your device, and you can clear it on that page at any time.
- which worlds you have saved for later: just each world and the time you saved it, up to 300. This is the list on your account's Saved page, the same on every device. You choose it yourself, it says nothing about you, and you can remove any world from it on that page at any time.
We do not store your name, your picture, your email address, postal address, IP address or anything about your payments, and we do not keep the access token Patreon issues during login: it is used once to read your membership and then discarded. We do not record which pages you look at.
This data is used only to decide which downloads to show you and to list the ones you made. The legal basis is the performance of the service you asked for (Art. 6(1)(b) GDPR). It is held in a database at Cloudflare, our hosting provider (section 2), and is not shared with anyone else.
Your profile page shows every item above with its real value, and lets you download it as a file. The account pages also list your active logins, each by its start and end time, which you can end one by one. Nothing extra is stored to do so. Your preferences (theme, reduced motion, sidebar, preferred download host) and the time you last opened the account dashboard are kept in your browser only and are never sent to us (section 4); clearing local data on the settings page removes them.
You can delete your account yourself at any time on the account settings page. That removes every item listed above immediately, and the cookies with it. A session ends after 30 days at the latest, and an account that has not been used for twelve months is deleted automatically. Deleting your account here does not affect your Patreon membership.
A member download sends you to the file on Google Drive or Proton Drive. From that point their privacy policies apply, as with any other link (section 6).
9. Your rights
Under the GDPR you have the right to:
- request access to the personal data we hold about you,
- have inaccurate data corrected,
- have your data erased,
- have processing restricted,
- object to processing based on legitimate interests,
- receive your data in a portable format,
- lodge a complaint with your national data protection authority. The EDPB member list links to the authority for each country.
In practice there is very little to request. Without visitor tracking, we hold almost nothing about ordinary visitors beyond the short-lived server logs described in section 2. If you have logged in with Patreon, the few items listed in section 8 are everything, and you can remove them yourself on the account settings.
10. Changes to this policy
If we add anything that changes the picture (analytics scripts, embedded players, a contact form), this page is updated first and, where the law requires it, you will be asked for consent before that feature runs.
