We don’t collect
anything.

DataWeave Studio has no account, no sign-up, no telemetry and no analytics. Nothing you write or run is sent anywhere. That isn’t a policy choice we could quietly reverse — it’s how the app is built.

Last updated: 22 August 2026

What stays on your device

Everything you work with stays on your machine:

• Your DataWeave scripts, payloads, sample data and test cases
• Saved workspaces, custom modules and snippets
• Encryption keys and secure-property values you enter
• Settings, configuration and logs

Transformations run on a DataWeave engine bundled inside the app, on your own computer. Your scripts and data are never uploaded, and the developer has no way to see them — which is exactly why it’s safe to paste a production payload into it.

When the app uses the internet

The app is fully usable offline. It makes network requests in only three cases, and none of them include your scripts, your data, or anything identifying you:

1. Checking for updates. The desktop app asks a static file on ashutosh-vijay.dev whether a newer version exists. You can turn this off in Settings → Advanced. It is disabled entirely in the Microsoft Store version, where Windows handles updates.
2. Downloading a Java library. Only when you explicitly ask the Java tester to fetch a library from Maven Central (repo1.maven.org).
3. Opening a link you clicked. For example “Send feedback”, which opens a pre-filled GitHub issue in your normal browser. Nothing is sent automatically — you decide what to submit.

The built-in MCP server

DataWeave Studio can run a local MCP server so AI coding assistants on your machine can validate DataWeave against the real engine. When you start it:

• It listens on 127.0.0.1 — your machine only, never exposed to your network
• It is off by default, and runs only while you choose to run it
• Scripts sent to it are executed locally and are not transmitted anywhere

Third parties and children

There are no third-party analytics, advertising, tracking or data-sharing services in this application. No data is sold or shared, because none is collected. The app is a developer tool and is not directed at children.

Your rights

Because no personal data is collected, there is nothing to request, correct or delete. Everything you create lives on your own device, and you can remove it at any time by deleting your workspaces or uninstalling the app.
