    About

    Klleyy's Hearts is a multiplayer PvP mod that gives each player three lives, banning them when they lose all three if that rule is enabled. Attacking an opposing player starts a 30-second combat phase, and a player loses a heart if they die during it or leave the game while it is active; attacks against teammates do not trigger combat. Players can give hearts to one another, and servers can enable linked hearts, which are shared by a paired couple and lost for both players if either loses the shared heart. Administrators can check or set a player's heart count, while server rules control banning, heart trading, linked hearts, and whether remaining combat time appears in the action bar. An admin-only Soul Amulet can preserve a heart after a combat death, and optional public chat notices report where it is dropped and who picks it up.

    Written from Modrinth and CurseForge . How we write it

    In-game changes

    Does not change the game's code directly.

    Adds 1 block: Klleyys Hearts Data Block; 2 items: Klleyys Hearts Data Block and Soul Amulet; 3 sounds: Hear Break Sfx, Heart Break Sfx and Heartbreak; 2 advancements.

    Counted from the names and data files in the mod, so the list may not be complete.

    Keeps all of vanilla Minecraft's textures, models and sounds.

    Security

    No harmful code found

    We checked its files and read their code, without running it.

    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 · All 6 latest files checked, last on 16 Oct 2026
    • 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.
      6 latest files: the newest file for each Minecraft version and loader. All 6 are 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 without running it
    • Author on ModrinthThe disclosure form on Modrinth, where the author declares that the project reads or edits things on your system outside the game. Since 13 Aug 2026, Modrinth's rules require it when this applies.
      Nothing declared about your system outside the game.
    • Looked for, not foundWe looked for these in the file and did not find them.
      The internet, folders outside the game, other programs, updating itself, the webcam or microphone, an AI service.

    Privacy

    We found nothing it sends

    We read its code without running it: it contacts no web address while you play.

    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 · All 6 files read
    • 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 all 6 files, for recent Minecraft versions. See each file in Releases
    • Author on ModrinthThe disclosure form on Modrinth, where the author declares crash reports, usage data and advertisements. Since 13 Aug 2026, Modrinth's rules require it when a project collects data on its users or shows advertisements.
      Nothing declared about crash reports, usage data or advertisements.

    AI

    No sign that AI was used to make it

    We looked for AI tools in its texts, files, images and sounds 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.
