NULLSPARK sends nothing to me. It talks to these services, only to do the job you asked for:

• Microsoft and Xbox Live, to sign you in.
• Mojang, for your Minecraft profile and skin, the version list, the game files and Java.
• Fabric and Legacy Fabric, for the mod loader.
• Modrinth, to search and download mods.

Each of those has its own privacy policy. Your login token is stored on your PC only, encrypted so only your Windows account can read it. Settings and logs stay on your PC too, in %APPDATA%\NULLSPARK. Uninstall and delete that folder and it's all gone.

• NULLSPARK is free to use. Please don't sell it or pass off a changed copy as the official one.
• It's provided as is, with no warranty. I test it, but I can't promise it works on every PC or never loses anything. Back up worlds you care about.
• You still have to follow the Minecraft EULA and the rules of any server you join. Using NULLSPARK doesn't change either.
• Mods you install belong to their authors and come under their licenses, as listed on Modrinth.
• These terms can change; the date at the top says when they last did.

• Mods come from Modrinth through its public API. Thanks to Modrinth and every mod author on it.
• Mod loader: Fabric and Legacy Fabric.
• Built-in Java: Eclipse Temurin by Adoptium, under GPLv2 with the Classpath Exception.
• Fonts: Tektur, Chakra Petch and Share Tech Mono, under the SIL Open Font License (license files are in the fonts folder).
