Server Information

FastStats helps plugin and mod developers answer questions such as:

• How many servers are using a plugin
• How many players are affected overall
• Which server software and versions are commonly used
• What errors are occurring in their plugins or mods

This information allows developers to:

• Prioritize bug fixes and compatibility
• Decide which platforms and versions to support
• Measure general adoption of their projects

FastStats is not used for advertising, tracking individual servers, or identifying players.

When a plugin or mod includes FastStats, the following information is collected by default:

• Server software name (e.g. Hytale, Paper, Folia, Velocity)
• Server software version
• Online / offline mode status
• Current player count
• Plugin or mod name
• Plugin or mod version
• Server ID (randomly generated)
• CPU core count
• Operating system name
• Operating system version
• Operating system architecture
• Java version
• Java vendor

Additionally, plugins and mods may opt in to error tracking, which collects:

• Error messages and stack traces from the plugin or mod itself

When error tracking is enabled, all error data is automatically anonymized:

• Folder paths that may contain usernames are redacted (e.g., /home/name, /Users/name, C:\Users\name)
• IPv4 and IPv6 addresses are redacted
• The system username (user.name property) is redacted
• Errors are deduplicated to avoid transmitting the same error multiple times

All listed data points are always collected together. There is no option to selectively disable individual values. However, error tracking and additional metrics (custom metrics collected by the plugin developer, not built in by FastStats) can be disabled independently.

FastStats is designed to avoid collecting personal or identifying data. Specifically:

• No IP addressesAll requests are proxied. FastStats never receives or stores your server's IP address. Only an approximate country is inferred by Cloudflare.
• No player dataNo usernames, UUIDs, or other player identifiers are collected.
• No server fingerprintingFastStats does not attempt to uniquely fingerprint or track servers across reinstalls.
• No personal dataData that could reasonably identify a person or make a server uniquely traceable is not collected.

The server ID used by FastStats is internal, randomly generated, and not publicly derivable.

All data sent to FastStats is handled in an anonymous and aggregated manner.

While FastStats uses a server ID internally to prevent duplicate counting, this identifier:

• Can be regenerated by the administrator
• Is not exposed publicly
• Cannot be used to identify your server by third parties

FastStats does not sell or share collected data with external parties.

Enabling FastStats has no noticeable performance impact on your server. Metrics are lightweight and sent at low frequency.

By default, a request without errors is around 215 bytes (±15). Error tracking, when enabled by a plugin, has minimal network overhead. With an error included, the request is around 400 bytes, meaning each error adds approximately 200 bytes. Errors happen very infrequently, are transmitted every 30 minutes alongside normal metrics, and are deduplicated to prevent sending the same error multiple times.

As a server administrator, you are always in control.

You can:

• Disable metrics collection entirely
• Re-roll (regenerate) your server ID

Metrics collection is enabled by default, but:

• No data is transmitted unless a plugin explicitly includes FastStats
• Plugin developers must opt in by integrating FastStats into their plugin
• Administrators may opt out at any time

To opt out, set enabled=false in your plugins/faststats/config.properties file.

If you believe a plugin or mod is misusing FastStats, please report it.

FastStats has a formal Terms of Service that plugin developers are required to follow.

These terms provide more detailed and legally binding explanations of acceptable usage.
