I've been working on a very simple, transparent and open Analytics mod for Minecraft to allow the community to openly gain inside into the versions of Minecraft out there. The mod strictly respects Snooper settings.
The mod allows custom mod integration for other mod makers to send in their own data.
The data collected by the mod:
Each individual value is individually opt-out-able by the user by going to Mods -> Forge Analytics -> Config
This view also shows a snapshot of what data and their values is sent.
Source code and public dashboard to be released very shortly.
The mod is free to use in any modpack.
