Providers and subprocessors
Last updated: August 4, 2026.
The third parties involved in processing your data: what each one does, exactly what it receives, and which country it operates from.
The full list
Wurz acts as a processor of the data you entrust to it, and to provide the service it relies on the providers below. All of them receive only what they need for their task. None of them receives your credentials for another service.
| Provider | What it does | What it receives | From where |
|---|---|---|---|
| OpenAI, L.L.C. | Reads each document and writes its summary and references, generates the chat's answers, and plans and writes Cowork reports. | Chunks of the document's text, up to 30 thousand characters each (the full text split across several readers when you request an in-depth read), your question, the summaries of the documents within scope, and the literal citations already verified against their source excerpt. Never the complete original files. | United States |
| Google LLC | Stores the original files in the Google Drive of the workspace owner, and provides sign-in with a Google account. | The complete original file, exactly as you uploaded it, and your Google account data. | United States and the other countries where Google operates data centers |
| Clerk, Inc. | Manages accounts, passwords, and sign-in sessions. | Your name, your email, and the technical data of each sign-in. | United States |
| Railway Corp. | Hosts the Wurz API, its database, the work queue, and the temporary memory where working copies live. | Everything Wurz keeps: summaries, references, metadata, and accounts. | United States |
| Vercel Inc. | Hosts this site and the web application you use in the browser. | Technical logs of the requests your browser makes. | United States |
| Resend | Delivers the service's emails: workspace invitations and account notices. | The recipient's email address and the text of the message itself. | United States |
| Stripe, Inc.Not yet active | Will charge the paid plans once billing is switched on. | Your payment and billing data. Wurz does not store your card number. | United States |
One piece is not on the list because it isn’t a third party: the component that converts scanned documents to text runs inside our own infrastructure. That content doesn’t go out to any external provider during that step.
When this list changes
Switching providers isn’t an implementation detail when the provider receives the content of your documents. If we onboard a new one that receives that content, this page changes with its update date and we notify you by email before it goes into operation. If that doesn’t suit you, you can cancel without penalty.
Pending definition
Everything above describes what Wurz does today. What follows hasn't been decided yet, and that's why it doesn't appear above: we'd rather show you the gap than plug it with something we couldn't honor.
- The signed contract with each provider documenting that it processes the data only on our instructions, with confidentiality, and without using it to train its models.
- The specific region where each infrastructure provider hosts the data.
- The formal mechanism to notify you before onboarding a new provider, and the period you would have to object.
