Your data and the AI
What stays on the Nelix server, and what is sent out when you use an AI feature.
Your designs stay on our server. Builds and simulations run on Nelix's own server, in isolated containers with no internet access.
When you use an AI feature, only what it needs is sent to the AI provider: your question, the relevant source and test files, log excerpts, and any screenshot you paste. Your name and e-mail are never sent to the AI provider.
Builds and simulations#
- Every build and simulation runs on the Nelix server, in a container with no network access. See How runs are isolated.
- Your project files are stored on the Nelix server, in your own folder.
When you use an AI feature#
Nelix Agent, Design Chat and the fix and repair features send a request to the AI provider. The provider is Anthropic, or the provider of your own key if you added one.
| Sent | Not sent |
|---|---|
| Your question or chat message | Your name |
| Up to 6 design files and 6 test files, each cut to 64 KB | Your e-mail address |
| Short excerpts of build and test logs | Your password or account details |
| A screenshot, only if you paste one | Files the feature does not need |
- With your own key, the request goes straight from the Nelix server to your provider, with the same content.
- If you turned on fallback for your key and your key fails, that request is answered by Nelix's own provider instead, and the answer says so.
- How long the provider keeps a request is set by the provider's own terms, not by Nelix.
Payments and e-mail#
- Payments go through Stripe. Stripe receives your e-mail address, never your designs.
- Lab e-mails (sign-up, invitations, password reset) are sent through an e-mail delivery service. They contain your name and links, never your designs.
Backups#
- The server is backed up every day. Copies kept off the server are encrypted before they leave it.
