Privacy: your work stays on your machine.

Most design tools start by asking who you are. OpenDesign starts by opening. There is no account to create, no profile to fill in, and no server quietly collecting what you make. This page explains exactly what that means in practice.

No account, no signup

There is no login, no email capture, and no cloud sync you have to opt out of. You download OpenDesign, open it, and start working. We do not have a user database because there are no users to put in one.

Local-first by default

On first launch, OpenDesign makes zero network requests. Nothing about your project (prompts, generated designs, imported files, settings) leaves your disk unless you choose to connect a cloud provider.

All of your state lives in one place on your own machine:

• ~/.opendesign/ on macOS and Linux
• %APPDATA%\opendesign\ on Windows

That directory is the whole story. Back it up, move it to another machine, or delete it. If you delete it, everything resets to a clean first launch. There is no hidden copy elsewhere.

BYOK and third parties

OpenDesign is bring-your-own-key (BYOK). When you add a provider key and run a generation against a cloud model, the request goes directly from your machine to that provider. Your prompt and your data are handled under that provider's privacy policy, not ours, because we are never in the path.

• Your keys stay local. Credentials are stored in your operating system's keychain (Keychain on macOS, Credential Manager on Windows, the Secret Service on Linux). They are never transmitted to us.
• Every outbound call is logged, on your machine. OpenDesign keeps a local, append-only record of network calls in ~/.opendesign/audit.log, so you can see for yourself what left the machine and when.

If you only use local models, you can run OpenDesign fully offline, and nothing ever leaves your computer.

No mandatory telemetry

OpenDesign does not phone home. Any usage analytics are strictly opt-in and off by default, behind a visible toggle you control. If you ever choose to turn them on, they carry no user id, no email, and no device fingerprint. There is nothing there to tie activity back to you personally.
