The short version
- This website sets no cookies, has no analytics and loads no third-party scripts or fonts.
- Nether Client sends pseudonymous performance reports, linked to a random install id and never to your account. It tells you before the first one, and one switch turns them off.
- The profile gallery sends nothing until you open it.
- Nether Launcher contacts Microsoft, Mojang, Fabric, Modrinth and our download server to sign you in, install the game and its mods, and update itself. Crash reports leave your computer only when you say so.
- There are no ads in the client, the launcher or this site.
This website
netherclient.com sets no cookies, stores nothing in your browser, has no analytics or tracking and loads no scripts, fonts or images from other companies. Every file comes from our own server.
Like any website, the servers that deliver it process your IP address, the page you ask for and your browser’s user agent in order to send the page. That is our server and Cloudflare, which sits in front of it. The download page reads the list of current installers on our server; your browser contacts our download server, downloads.netherite.gg, only when you start a download.
Nether Client
Performance reports
They tell us how the client performs on real computers, so we can make it faster. Before the first report, a notice on the title screen explains them and offers Turn off.
What a report contains: frame-time, stutter and memory statistics; the versions of the client, Minecraft, Fabric and your other mods (their ids and versions); your operating system, processor, memory, graphics card, driver and monitor; Java version and garbage collector; your video settings; which HUD modules are on; and whether you are in a menu, in singleplayer or on a server.
What it never contains: your Minecraft or Microsoft account, name, UUID or tokens, the address of any server you join, your chat or your files.
How it is linked: to a random install id made on your computer, plus a random id per session. Our server stores only a keyed hash of the install id.
Where and when: to netherite.gg, in batches, by default every 15 minutes while you play, the first one about a minute after the title screen appears. Reports nobody asks us to delete expire after 180 days.
How to switch it off: in the client, open the hub (Right Shift), then Settings, Privacy, Share performance reports. In the launcher, Settings, Privacy, Share performance reports; switching it off there also locks it off in the client. Switching off sends one request asking our server to delete what was sent, then deletes the install id from your computer.
Profile gallery
Nothing is sent until you open the gallery. Browsing asks our gallery server for the list of profiles. Liking, reporting and publishing need you to sign in first, and sign-in uses your Minecraft account through Mojang’s own session check: the client asks our server for a one-time challenge, tells Mojang’s session server it is joining with that challenge, the way the game does when you join a server, and our server confirms it with Mojang. Your Minecraft token goes only to Mojang. No password or token is sent to us.
We store your Minecraft UUID and name, the profiles you publish (their name, description, visibility and the look and layout of your modules), your likes and your reports. A shared profile never includes your audio devices, volumes, mute state or key bindings. To keep all of this off, do not open the gallery.
Voice chat
Voice chat is off until you turn it on, and it works only on servers that support it. Your voice then goes to the voice service that server points the client to, directly or, when a direct connection is not possible, through your game connection. If you report a speaker, the report carries their player id and your reason.
When you join a server
The client sends the server a short hello with the client’s version, the game version and the names of its modules. It contains nothing about your account.
The client makes no other network requests of its own: no ads, no news feed and no other tracking.
Nether Launcher
| Who | What for | Can you switch it off? |
|---|---|---|

| Fabric | The Fabric loader for Fabric instances. | Needed for Fabric instances. |
| Modrinth | Browsing, installing and updating mods; recognising mods you added. | Automatic checks: yes. Browsing and installing: only when you do it. |
| Our download server | Updates for the launcher, the client and its managed mods. | Needed to stay up to date. |
| netherite.gg | Crash reports, only when you send one; performance reports from the client. | Yes, both. |
Signing in
You sign in on Microsoft’s own page in your system browser; the launcher never sees your password. It then asks Xbox and Minecraft services for your Minecraft profile. The token that keeps you signed in is stored in your operating system’s keychain, never in a plain file; the launcher’s own account list holds only your Minecraft UUID and name and your Xbox user id and gamertag.
Modrinth
Browsing sends your search text and filters. Opening a mod, installing and updating send the ids of the projects and versions involved. Installing, checking for updates and recognising .jar files you added send the SHA-512 hashes of the instance’s mod files, never the files themselves. Requests go to api.modrinth.com and icons come from cdn.modrinth.com; Modrinth sees your IP address. Automatic update checks, recognising your .jar files and loading mod names and icons happen on their own only while Contact Modrinth automatically is on, under Settings, Launcher. With it off, the launcher contacts Modrinth only when you browse, open a mod, install, update or check for updates.
Updates
The launcher reads its update list from downloads.netherite.gg when it starts and every 15 minutes while it is open, and downloads new versions from there, checking each file against its SHA-256 hash.
Crash reports
When the game crashes, the launcher asks before it sends a report, unless you turn on Send crash reports automatically under Settings, Privacy (off unless you turn it on). A report contains the launcher, game and mod versions, your operating system, the error and its stack trace, Minecraft’s own crash report, the end of the game log and your Minecraft name. Your home folder’s path is shortened to ~ and account tokens are removed before it is sent.
Your data and requests
To have your performance data deleted, switch performance reports off: that sends the delete request. To ask for a copy of your gallery data, or to have it or anything else we hold about you deleted, ask us on Discord, our public support channel.
Changes and contact
When the client, the launcher or this site changes what it sends, we update this page and the date at the top. Questions go to our Discord.
