Telemetry

DoubleDoors uses anonymous telemetry to understand how the plugin is configured and to improve reliability. This page explains what is collected, where it is published, and how it is used.

Your choice​

Telemetry is enabled by default, but you can opt out at any time.

You should also change telemetry in plugins/faststats/config.properties by setting enabled to true or false depending on your preference.

All telemetry is anonymous and publicly available on the DoubleDoors FastStats page.

How data is collected​

The plugin collects configuration and runtime information from the server where DoubleDoors is installed. Configuration values are reported as metrics rather than as a copy of config.yml. Error reports are sent when the plugin captures a crash or error and include the diagnostic context needed to investigate it.

How data is stored and used​

FastStats stores the submitted metrics and makes the aggregated project data public. The data is used to understand feature adoption, monitor compatibility across server platforms and versions, measure continued usage, and investigate plugin errors. It is not intended to identify individual players or server owners.

Collected data​

Custom data specific to DoubleDoors​

Bukkit only​

Also applies to Spigot, Paper, etc.

  • Server Language The server language set in the config (e.g. en_US)
  • Player Language The language set by the player (e.g. en_US)
  • Data Storage Type How data is stored: YAML, SQLite, MySQL, or unknown
  • Auto Close Enabled Whether auto-close is enabled
  • Knocking Enabled Whether the knocking feature is enabled
  • Update Checker Enabled Whether the update checker is enabled and whether PluginUpdater is installed
  • Debug Mode Enabled Whether debug mode is enabled
  • Recursive Opening Distance The recursive opening distance, or 0 when the feature is disabled

Error reports​

  • Crash and error details, including stack traces
  • Basic server software, Minecraft version, and plugin version information included with the report

Error reports are used to diagnose failures and prioritize fixes.

Error anonymization​

Source: FastStats

When error tracking is enabled, all error data is automatically anonymized before transmission.

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

Standard FastStats data​

Source: FastStats

FastStats also collects standard project metrics by default:

Server​

  • Server ID Randomly generated identifier used internally to prevent duplicate counting
  • Player count Current number of online players
  • Online mode Whether the server runs in online or offline mode
  • Country Approximate country inferred from Cloudflare — your IP address is never stored

Software​

  • Platform Server software name (e.g. Paper, Folia, Velocity, Fabric)
  • Platform version Version of the server software
  • Game version Version of Minecraft (e.g. 1.21, 26.1.2)
  • Plugin version Version of the plugin or mod that includes FastStats
  • Client mod Whether the mod runs on the client rather than the server

System​

  • Operating system OS name (e.g. Windows, Linux, macOS)
  • OS version Operating system version
  • OS architecture CPU architecture (e.g. x86_64, aarch64)
  • CPU core count Number of CPU cores available to the server

Java​

  • Java version Runtime version (e.g. 21.0.2)
  • Java vendor Java distribution vendor (e.g. Eclipse Temurin, Oracle)

What is not collected​

Source: FastStats

  • No IP addresses All requests are proxied. FastStats never receives or stores your server's IP address. Only an approximate country is inferred by Cloudflare.
  • No player data No usernames, UUIDs, or other player identifiers are collected.
  • No server fingerprinting FastStats does not attempt to uniquely fingerprint or track servers across reinstalls.
  • No personal data Data 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.

Anonymity & Privacy​

Source: FastStats

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.

Performance Impact​

Source: FastStats

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

  • Default request: ~215 bytes (±15)
  • With one error: ~400 bytes
  • Per error added: ~200 bytes

Error tracking, when enabled by a plugin, has minimal network overhead. Errors happen very infrequently, are transmitted every 30 minutes alongside normal metrics, and are deduplicated to prevent sending the same error multiple times.
