About
PolyPlus is OneClient’s companion mod, bringing online hosting and social features into Minecraft. Players can host a selected world for friends without port forwarding, choose its game mode and whether cheats are allowed, invite individuals or groups, and share the resource pack with visitors; ordinary LAN hosting remains available, and hosting works with Simple Voice Chat. Its social menu supports adding friends by username, direct messages, group chats, blocking players, and viewing or rejoining world invitations. Cosmetics include capes, wings, hats, glasses, gloves, boots, auras, back and shoulder items, plus pets on modern versions and emotes; players can browse owned and store items and choose whose cosmetics are visible. PolyPlus also adds chat emoji with shortcode suggestions and a picker, along with a redesigned title screen featuring Quickplay for recent servers, a player preview, account switching, and featured servers; its parts can be hidden or the vanilla menu restored. A first-launch setup screen offers controls for toggle sprint, motion blur, GUI scale, and other OneClient mods, while additional extras include a memory-allocation warning and the Polydium performance mod. Online features such as hosting, friends, chat, and cosmetics require accepting Polyfrost’s Terms of Service and Privacy Policy.

- It can use the login of your Minecraft account, for example to join a server. It can read the login token of your Minecraft account and use the login to join a server.Not a Warning: only reading its code can show where the login token goes, and we have not read the code of this file yet.

- Connects to the internet
- It has code that can go online, for example to check for updates, load skins or send crash reports. Found in the mod's own code, in code libraries built into it and in 4 libraries it includes. See Privacy
Why we show this: a mod runs on your computer like any program, so harmful code in it can take your accounts or files. Our checks look for known signs of harm. They cannot prove that a file is harmless. In the grade: malware means no grade, and a Warning in a latest file for a recent Minecraft version lowers it.
How we checked
- FilesWe download the files from Modrinth or CurseForge and look at what is inside them and what their code can do, without running them. Fixed rules tell what is harmful.19 latest files: the newest file for each Minecraft version and loader. The answer above is about the 18 for recent versions. Recent versions: those released in the last 2 years, plus 1.20.1 and 1.21.1, among the most played in modpacks. See each file in Releases
- Their codeWe turn the code of the files back into readable code and follow what it does, without running it. This shows what it downloads, what it sends and where your login goes.Read in 9 of 18 files, without running it

Privacy
Sends crash reports, and uses your Minecraft login
Sent to an address built while the game runs.
We found this in its code, read without running it.
We have read the code of 9 of its 18 files for recent versions.
The author declares on Modrinth that it sends crash reports or usage data only if you agree, and that it shows advertisements.
Why we show this: a mod can send things about you over the internet, like your player name or your login. Contacting an address to check for updates or download files sends nothing about you. Not in the grade: sending data can be normal for what a mod does.
How we checked
- Files readWe read the code without running it. We list each web address the code contacts while you play, and what it sends. Code that is never used is left out.The code of 9 of 18 files, for recent Minecraft versions. See each file in Releases
- sessionserver.mojang.comTalks to an online service the mod works with.Login check with Mojang
- Address built while the game runsThe code builds this address while the game runs: it is not written in the file.Connects directly to other players for voice chat. Uploads crash reports or logs.Crash reports
- Named in its filesA crash report or usage data service named in the files of the mod. The code does not show when or what is sent.The code names Sentry, a service that receives crash reports.
AI
No sign that AI was used to make it
We looked for AI tools in its texts, files, images and code history and found none.
No sign of AI in the game
We found no AI service, AI library or AI model file in its code.
Why we show this: some players and servers avoid projects made with AI, and AI in the game can send what you write to an online service. Not in the grade: using AI does not tell whether a project works well or is kept up to date.
How we checked
- Author on ModrinthThe disclosure form on Modrinth. Since 13 Aug 2026, Modrinth's rules require it when a substantial part of the code is AI output, when an asset is mainly AI output, or when the project or its page relies on generative AI.No AI content or AI features declared.
