Windmill leverages AI to clean, summarize, parse, and aggregate data to make it more useful for HR teams and managers. This page explains how we use AI, what data the AI processes, and how we protect your information.

​
AI models and providers

Windmill uses state-of-the-art AI models from trusted providers: These models power Windy, our AI agent, to help with feedback collection, recap generation, and performance insights. Zero data retention Windmill has zero data retention enabled across all AI model providers. This means:
  • Your data is not stored by our AI providers after processing
  • API calls are processed and immediately discarded
  • No logs or caches of your data are retained by OpenAI, Anthropic, or Google
Zero data retention ensures that your company’s data never becomes part of AI provider training datasets or storage systems.

​
Data retention

Windmill retains data from customers as long as they have an active engagement with Windmill. Customers have the right to request complete data deletion after ending an engagement.

​
Telemetry

To enhance the performance and accuracy of our AI models, Windmill collects telemetry data, encompassing inputs and outputs of AI interactions. Access to this data is strictly limited to authorized personnel, underpinned by robust security protocols and comprehensive audit logs, safeguarding customer information while facilitating continuous improvement of our AI solutions.

​
Model training

We do not train public models on your data. Here’s what that means:
  • Windmill does not build or train generalized AI models from customer data
  • Any custom AI models we train are for internal use only, strictly to operate and enhance our product
  • We never train models to be made available as a standalone service or via an external API
  • When we train custom models, they’re exclusively derived from generated synthetic datasets
  • Our vendor partners (OpenAI, Anthropic, Google) do not use logs to train their own models
  • With zero data retention enabled, your data never persists in vendor systems
Your data stays your data. We never use your company’s information to improve models that serve other customers.

​
Prompt engineering

The optimization of AI performance is a continuous endeavor at Windmill. Our team regularly examines telemetry logs to refine and improve AI prompts, enhancing the relevance and accuracy of AI-generated content. This process is conducted with the utmost respect for privacy—no private customer data is incorporated into prompts or used in any unauthorized manner.

​
Model accuracy and quality

Generative AI, while powerful, can sometimes yield unexpected outcomes. Windmill is committed to mitigating instances of low-quality, incoherent, incomplete, or insensitive content. We employ rigorous quality control measures and are dedicated to iterative enhancements of our AI capabilities. If you encounter any issues with AI-generated content, please report them to support@gowindmill.com.

​
AI attribution in reports

Windmill attributes engineering work and contributions based on activity in connected systems like GitHub. Commit attribution Commits are attributed based on the author of the commit, which is configured in local git configuration (not GitHub user identity). To ensure commits are attributed correctly, configure your local git: 
git config user.name "John Doe"
git config user.email "john.doe@example.com"
Coding agents If you use coding agents, attribution depends on how the agent interacts with GitHub: Attributed to a bot user:
  • Devin
  • Claude Code (via GitHub Actions)
Attributed to the requesting user:
  • OpenAI Codex
  • Cursor
  • Claude Code (locally)
If you notice incorrect attribution in your Recaps or reports, check your git configuration and coding agent settings.

Continuous improvement

Windmill values customer feedback as an essential component of our AI development cycle. We’re dedicated to the ongoing enhancement of our AI solutions and encourage clients to provide input and report any issues. Your feedback directly influences our improvement strategies and helps us serve you better. Reach out to support@gowindmill.com with any concerns or suggestions.
