WIND
Privacy policy
This page explains what data WIND collects when you use the launcher, why, and what we do with it. WIND is built by a solo developer, not a company with a data team, so we try to collect as little as possible.
Your Microsoft and Minecraft account
Playing Minecraft requires a Microsoft account, and that login happens directly with Microsoft, not through WIND. We never see or store your password. WIND stores the session token needed to keep you logged in and your Minecraft profile info (username, UUID, skin) so the launcher can work.
Friends and presence
If you use the friends list, we store who you're friends with and your online status so that feature works. This data lives on our own servers and isn't shared with anyone outside of what's needed to show it to your friends inside WIND.
Crash logs
When you use the crash assistant, your crash log is first sent to Jev (an AI model by TypeSafe), which quickly checks what went wrong and suggests a fix. If Jev isn't sure, or if you ask for a more detailed analysis, the log is also sent to Google Gemini. Along with the log we send a few technical details about your setup that help find the cause, such as the Minecraft version, your installed mods and your RAM and Java settings. We never send your account details. If you'd rather not use this feature, you can always read the crash log yourself instead.
Launcher usage statistics
To find out where new players get stuck, the WIND launcher sends a few anonymous usage events to our server: that it was opened, which step of the introduction was shown, whether the Microsoft sign-in and the Minecraft start worked (with the error message if they didn't), and how long a game session lasted. Each event carries a random installation ID created on your PC, the launcher version and a timestamp. It doesn't include your Minecraft name, your account ID or any of your files. The first time the launcher opens, we also store a one-way hash of your IP address, the same kind we already keep for downloads, so we can count how many downloads lead to a launcher that actually gets opened.
Mods, Modrinth and CurseForge
Browsing and installing mods, modpacks, resource packs and shaders happens through the public APIs of Modrinth and CurseForge. Both have their own privacy policies that apply to that part of the experience.
Playing together and hosting servers
When you share a world with friends, WIND connects your PCs directly (peer-to-peer). Our servers only help the two sides find each other, the game itself runs directly between you. Like any direct connection, this means the friends you play with can see your IP address.
If you host a server and make it public with a WIND Tunnel, connections to your *.play.windlauncher.com address are routed through our tunnel service to your PC. The address you choose is linked to your WIND account so nobody else can take it.
What we don't do
- No ads, and no selling or renting out your data to advertisers
- No tracking across other websites or apps
- No analytics that identify you personally
Data security
Account and chat data is stored on our own server with encryption at rest where it matters (like chat messages). No system is perfectly secure, but we take reasonable steps to protect what we store.
Children's privacy
WIND follows the same age requirements as Minecraft itself, set by Microsoft's account terms. We don't knowingly collect extra data from children beyond what's needed to run the launcher.
Changes to this policy
If this policy changes in a meaningful way, we'll update the date at the top of this page.
