Mercurius Mod 1.12.2, 1.11.2 collects data about your current client/player/server sessions and reports this back to our central stats server for processing.

Mercurius Mod

Is there any personally identifiable data? Absolutely not. Access logs have been disabled for the API ingest and your IP address is not stored with stats data. We have no way of knowing who a row of data belongs to.

Mercurius Mod 1


  • SessionID: Several versions of this exist, including a Client Session and a “Play Session”. Generated when you start your client, and a unique ID generated when you start a world or join a server. Generated with random unidentifiable information.
  • InstallID: This is a unique ID given to a modpack installation, constant through the life of that installation.
  • Modpack: Name of the modpack you’re playing (as indicated by the modpack developer)
  • Forge Version: The version of Forge you are running.
  • Java Version: The version of Java you are running.
  • Minecraft Version: The version of Minecraft you are running.
  • Start Time: Sent with Client start and Play Session start.
  • End Time: Sent with Play Session (not currently sent with Client exit)
  • Installed Mods/Versions: A one time packet sent with the information of all mods installed and their status (enabled/disabled) and their versions.

Mercurius Mod 2

How it works?

  • When starting the client, the initial packet is sent to stage the statistics data for your session. Upon starting a world, a similar packet is sent (you may make changes while in the client before starting a world). The client pings every 5 minutes to let us know that you’re still connected and sending data. When you stop a world, a small STOP packet is sent to let us know you’ve exited your world.
  • The largest packet is the initial packets sent that include the modpack information. This should have little impact on your bandwidth, even after long and frequent play sessions.
  • You can opt out globally by turning the snooper settings off in Minecraft which sends information back to Mojang. Out of courtesy and respect, we’ve decided that this is something we will absolutely respect as well. Additionally, if there is certain information listed above that you would prefer not send us, you can opt out invididually. Because we value the reliability of our statistics, some options aren’t available for you to opt out of indvidually, and do require you to opt out globally.
