Last updated July 30, 2026
This Privacy Policy describes how Digitteck ("we", "us", or "our") handles information in connection with Rhenergo, an AI-powered scripting add-in for Autodesk® Revit® (the "Add-in" or "Service").
Rhenergo includes features that route your input to external AI providers. This policy exists primarily to explain those data flows in plain terms. If there are any terms you do not agree with, please discontinue use of the Service immediately. Questions may be directed to [email protected].
Please read this notice carefully. The AI sections are not boilerplate — they describe real network activity that happens when you use the AI assistant.
Rhenergo is a desktop application that runs inside Autodesk Revit on your local Windows machine. The core add-in — the editor, Composer, Apps designer, and local storage engine — operates entirely offline. No telemetry, analytics, or usage data is transmitted to Digitteck or any server by the add-in itself.
The add-in also includes an AI assistant. When you use the AI assistant, your input is forwarded to an external AI provider of your choice. That is the network activity this policy is principally about.
In Short: When you use the AI assistant, your prompts and supporting context are sent to the AI provider you configured. That traffic is governed by the provider's own privacy policy, not ours.
Rhenergo supports the following AI providers:
Important
Digitteck does not act as an intermediary or proxy for AI requests. When you use Anthropic, OpenAI, or Google Gemini, Rhenergo calls their API directly using your API key. Your data goes to their servers. Digitteck never sees your prompts, your API key values, or the AI responses. We have no ability to review, retrieve, or delete data held by those providers. Any questions about how those providers store or process your data must be directed to them.
Each provider has their own data retention, training, and privacy policies that may change over time. You are solely responsible for reviewing and accepting the terms of any AI provider you choose to use with Rhenergo. Digitteck makes no representation or warranty about those providers' practices.
By entering an API key and enabling an AI provider within Rhenergo, you acknowledge and agree that your use of that provider's model is subject to that provider's terms of service, acceptable use policy, and privacy policy, and not solely to this document.
In Short: Prompts you write, script text, element counts, API type lookups, and error messages. Never raw Revit geometry as binary data. But if you describe sensitive content in your prompt text, that description is transmitted.
When you send a message to the AI assistant, Rhenergo constructs a request containing:
The following data is not sent to AI providers under any normal operating condition:
Your prompt text is the data
Rhenergo cannot inspect your prompt and redact sensitive content you have typed. If you copy client names, proprietary specifications, confidential room programs, grid coordinates, or any other sensitive information into the AI chat, that information is transmitted to the provider's servers verbatim. Review what you type before you send it. Treat the AI chat window the same way you would treat an email to an external party — because that is effectively what it is.
In Short: You control what you type. We are not responsible for what you choose to send to an AI provider.
Digitteck provides the mechanism that connects to AI providers. You decide what to include in your prompts. By using the AI assistant, you accept full responsibility for:
If your firm or project has restrictions on transmitting information to external cloud services, it is your responsibility — and your employer's responsibility — to determine whether using a cloud AI provider with Rhenergo is permissible. Rhenergo supports local Ollama models specifically to accommodate environments where no data may leave the machine.
Digitteck disclaims all liability for any claim, loss, or damage arising from information you choose to include in AI prompts, including but not limited to breaches of confidentiality, data protection violations, or professional misconduct.
In Short: Your API keys are encrypted on your machine using Windows DPAPI and never leave your device in plaintext. Digitteck never has access to your API keys.
When you enter an API key (for Anthropic, OpenAI, or Google Gemini), Rhenergo encrypts it immediately using the Windows Data Protection API (DPAPI). DPAPI ties encryption to your Windows user account and the local machine — no other user on the same machine can decrypt your keys, and the encrypted blob is unreadable if moved to another machine.
Your API keys are:
You are responsible for the API keys you create, their associated costs, and their security. If you believe an API key has been compromised, revoke it immediately from the provider's developer dashboard (Anthropic Console, OpenAI Platform, Google AI Studio). Revoking the key at the provider ends any ability to make requests under that key.
You are also responsible for monitoring and controlling usage costs incurred via your API keys. Rhenergo does not track, limit, or report your API usage. Cost management tools are available directly from each provider.
In Short: Scripts, Composer graphs, and Apps are stored locally on your machine. Digitteck does not have access to them.
All content you create in Rhenergo — IronPython scripts, Composer graphs, App definitions, and Collections — is stored on your local machine as compact binary records. This data does not sync to any cloud service operated by Digitteck, and Digitteck has no access to it.
Package files you explicitly export and share with colleagues are under your control. Sharing a package is your action; Digitteck is not a party to that transfer.
In the event of an error, Rhenergo may write a log file to your local machine containing the error message, stack trace, add-in version, Revit version, and operating system version. Log files are stored locally and are not automatically transmitted. If you contact support and choose to share a log file, please review it first and redact any sensitive project information before sending.
In Short: Digitteck does not collect, receive, or store any data from your use of Rhenergo.
Rhenergo does not include telemetry, crash reporting, analytics, or any mechanism that transmits data to Digitteck's servers. The add-in makes no outbound connections to Digitteck infrastructure. The only outbound network connections Rhenergo makes are:
Rhenergo is a professional tool intended for use by adults in architectural, engineering, and construction contexts. We do not knowingly collect information from individuals under 18 years of age. If you believe a minor is using the Service, please contact us at [email protected].
Because Digitteck does not collect or hold your personal data through the Rhenergo add-in, there is no personal data held by Digitteck for you to access, correct, or delete. Your data sits on your own machine or — when you use AI features — on the AI provider's servers under their terms.
To exercise rights over data held by an AI provider:
If you are in the European Economic Area, you have rights under the GDPR including access, rectification, erasure, restriction, and portability. These rights apply to data processors who hold your data — in the Rhenergo context, that means the AI provider you chose, not Digitteck.
If you have questions about privacy rights in connection with Rhenergo, contact us at [email protected]. We will respond within 30 days and direct you to the appropriate party where we are unable to act on a request ourselves.
In Short: Yes, particularly as AI provider terms and Rhenergo features evolve.
We may update this privacy policy when Rhenergo adds new AI providers, changes how it constructs prompts, or when applicable laws require it. The "Last updated" date at the top of this page will reflect the most recent revision. We encourage you to review this notice whenever you update the add-in or add a new AI provider. Continued use of the Service after changes are posted constitutes your acceptance of the updated policy.
