Privacy And Telemetry

Privacy & Telemetry

RevitDevTool includes optional, anonymous telemetry to help improve the platform. This page describes exactly what is collected, what is never collected, and how to opt out.

Purpose

Telemetry is used strictly for development and quality improvement:

• Identify critical crashes and unhandled exceptions across different host environments
• Understand which execution modes are actively used (Python, C#, F#, IronPython)
• Prioritize stability and performance work based on real-world usage patterns

Telemetry is not used for user profiling, advertising, or any commercial data collection.

What Is Collected

Session Usage Summary

One aggregated event is sent when the host shuts down. It contains only counts — no content:

Category	What is counted	Example
Execution	Number of script/assembly runs by mode	"Python: 12, C#: 3, IronPython: 0"
MCP	Number of MCP tool dispatches by backend type	"Assembly: 5, Python: 2"
Visualization	Geometry rendering calls by type (Revit only)	"curve: 8, solid: 2"
Logging	Log lines by severity level	"Info: 45, Warning: 3, Error: 1"

No script names, tool names, log messages, or file paths are included in usage summaries.

Critical Exceptions

When an unhandled crash occurs, an exception report is sent containing:

• Exception type and message
• Stack trace
• Host environment (Revit/AutoCAD version, DevTool version)

Exception reports help diagnose crashes that users may not report manually. Routine errors like cancellations and timeouts are filtered out and never sent.

What Is Never Collected

• BIM model content, geometry data, or project files
• Script source code or file contents
• Log message text or output content
• MCP tool names or parameters
• Document names, file paths, or project-specific data
• Windows username, email, or personal identity
• Network configuration or IP-based geolocation

Installation ID

A random UUID is generated once per machine and stored locally (%AppData%\RevitDevTool\installation_id.txt). This ID is used solely to correlate crash reports from the same installation — it is not linked to any user account, Windows identity, or Autodesk account.

How To Opt Out

Open RevitDevTool settings and disable "Anonymous diagnostics". When disabled, no telemetry data is sent. The change takes effect on the next host restart.

When telemetry is disabled, no network requests are made to the telemetry service.

Data Storage

Telemetry data is processed by Sentry hosted in the European Union (Germany). Data is subject to Sentry's data retention policies and GDPR compliance.

No telemetry data is stored locally beyond the installation ID file.
