Acceptance

By using Folium you agree to these terms. If you do not agree, do not use the launcher.

License

Folium is free for personal use. You may install and run it on computers you own. Redistribution is not allowed.

Minecraft and accounts

Folium uses official Microsoft authentication and never sees your password. Minecraft is governed by Mojang's and Microsoft's own agreements. Folium is not affiliated with Mojang or Microsoft.

Third-party content

Folium can install mods and packs from sources like Modrinth and CurseForge. That content belongs to its authors and is subject to their licenses. We do not create or vet it.

Acceptable use

Do not use Folium to break the law, access accounts you do not own, distribute malware, or bypass Minecraft's protections.

No warranty

Folium is provided as is. We do not guarantee it will always work, be error-free, or be compatible with every mod or setup. You use it at your own risk.

Changes

We may update these terms. Continuing to use Folium after a change means you accept the new terms.

The short version

Folium stores the account and service data needed to provide online features. We do not sell your personal data. Your launcher settings, instances and installed content remain on your computer.

Your Minecraft account

You sign in through Microsoft's official login. Folium never sees or stores your password. The login gives the launcher a token so it can start the game as you. That token and your profile are stored locally so you do not have to sign in every time, and signing out removes them.

What is stored on your computer

Your instances, settings, installed mods and login session live in Folium's data folder on your machine. Folium does not upload these anywhere.

Third-party services

Folium contacts these services only for the feature you are using. Each has its own privacy policy.

• Microsoft and Xbox Live: sign-in and the token that launches Minecraft as you.
• Mojang and Minecraft: account checks, game downloads and version files.
• Modrinth: searched when you browse or install content.
• CurseForge: also available for content, through a proxy that only forwards your query.
• Cloudflare: delivers launcher assets and updates, with standard request logs.
• Cosmetics: Folium stores the cosmetics your account owns and wears. Other players can look up the live cosmetics worn by a Minecraft account and download their artwork so the items appear in game. Beta cosmetics remain private to the designated test account.
• Discord: receives rich presence updates locally if Discord is running. If you link Discord in launcher settings, Folium stores your Discord account ID, username and avatar image identifier with your Folium account on Cloudflare. Unlinking removes the active pairing; minimal reward records may retain the Discord ID to prevent repeat payouts.
• Folium Discord bot: stores moderation history, active timed punishments and giveaway entries in MongoDB. Reward claims are checked with the Folium account service rather than stored by the bot.
• Crash reports: when you choose to send one, the launcher includes the crash log, Minecraft and launcher versions, exit code, and your PC's operating system, CPU model, GPU model, processor architecture and installed RAM amount. No hardware serial number is collected.

No ads or tracking

Folium shows no ads and includes no third-party tracking or analytics. We do not build a profile of you.

Changes

If this policy changes, the updated version is posted here.
