Privacy & Data

This mod collects gameplay statistics (kills, trophies, play time, installed mods) and sends them encrypted to the GCValheimStats server at https://gchallenge.ru.

The mod uses AES-256-CBC encryption with HMAC-SHA256 authentication to protect all data in transit. The encryption key is derived from your Steam ID and a hardware-specific identifier (machine name + processor ID). This ensures that data from different players cannot be decrypted by others.

The hardware identifier is used only to generate the encryption key and is never transmitted outside your machine. It consists of your computer name and processor ID, which are standard system properties read locally.
