Privacy Policy

Last updated 2 November 2026

The short version

1. Who we are

This policy explains how the team behind Wind Client ("we", "us") handles personal data when you use the Wind Client launcher, its in-game menus mod, its online features and the website windclient.com. We are the data controller for the data described here. You can reach us about anything privacy related at windsupport@windclient.com.

2. What stays on your computer

Most of what Wind Client handles never leaves your PC and we can't see it:

3. What we store online

So the launcher can keep your setup, it saves the following on our server, which runs on Cloudflare:

DataWhy
A random user ID and your install's public device keyTo recognise your install and keep your data separate from everyone else's. It isn't linked to your name or email
Minecraft account names, account type and Minecraft UUIDs you addTo show your accounts and skins in the launcher
Launcher settings, such as memory, Java options, window size and what happens after launchTo keep your settings
Your instances (name, Minecraft version, loader, dates) and saved servers (name, address, version)To show and launch them
Short-lived security codes and timestamps on each requestTo stop replayed or forged requests
Your IP address, used brieflyTo limit how many requests and new installs come from one network, which protects the service from abuse. We don't save it to our database

We don't collect your real name, email address, Microsoft password, payment details, precise location, contacts or anything you type in chat. We don't use analytics, crash reporting or advertising tools.

When the launcher checks for news or updates, it downloads them from the same server. Our hosting provider, Cloudflare, processes the technical details of those requests, such as IP address and time, to deliver them and keep the service secure.

4. Other services the launcher talks to

To do its job, Wind Client connects from your computer directly to these services. They receive your IP address and the details of the request, and handle that data under their own privacy policies:

6. Our legal bases

Under the EU and UK General Data Protection Regulation (GDPR) we rely on:

7. How long we keep data

8. Where data is processed

Our server and database run on Cloudflare, which may process data in the United States and other countries. Where data leaves the European Economic Area, it is protected by the EU-US Data Privacy Framework or the European Commission's Standard Contractual Clauses that Cloudflare provides.

9. Your rights

Depending on where you live, you have the right to:

Because we don't know your name or email, please tell us the Minecraft account names you use in Wind Client when you email us, and we'll help you find your install's data. We may ask for extra details to make sure the data is yours. We'll reply within one month. Exercising your rights is free and won't be held against you.

If you live in California or another US state with privacy laws, you have similar rights to know, delete and correct your data. We do not sell or share personal information for advertising.

10. Children

Wind Client is not meant for children under 13, and we don't knowingly collect data from them. If you are a parent and think your child under 13 has used Wind Client, contact us and we'll delete their data.

11. Security

Every request from the launcher is signed with your install's private key, which never leaves your computer. Sign-in tokens and keys are encrypted with Windows' built-in protection. Connections use HTTPS. No system is perfectly secure, so please keep your computer and Microsoft account secure too.

12. Changes to this policy

If we change how we handle data, we'll update this page and the date at the top. For significant changes we'll also give notice in the launcher, on our website or on Discord before they take effect.
