    About

    Serene Seasons Plus extends Serene Seasons with seasonal day-and-night timing and more responsive, realistic snow and ice behavior. Daylight and darkness shift with the current season, bringing longer days in summer and longer nights in winter; an optional setting can keep a complete day-night cycle at a chosen real-time length without tying it to the computer’s clock. During snowfall, snow accumulates progressively, with the mod tracking snow depth by area and supporting cloud-driven placement through Project Atmosphere so snow can fall where clouds produce it. Snow can build on leaf canopies as well as the ground, and melting removes layers progressively while taking biome temperature and winter conditions into account; ice is also handled by the snow-processing system. Integration with Better Days adjusts day and night lengths across the seasons and supports its sleep cycles, while the Canadian seasons preset aligns seasonal timing with average Montreal-area climate data.

    Security

    No harmful code found

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

    What it can do on your computer

    Connects to the internet
    It has code that can go online, for example to check for updates, load skins or send crash reports. Only in its files for Fabric 1.20.1 to 1.21.11. See Privacy
    Creates settings files
    The mod keeps its settings in the config folder of your game, where you can change or delete them. 1 file in your config folder.

    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 16 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.
      16 latest files: the newest file for each Minecraft version and loader. The answer above is about the 12 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.
      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 12 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 12 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 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.
