# Support

## Get in touch

Email [support@lumadisk.com](mailto:support@lumadisk.com). That reaches us directly, and it is the right place for anything touching a license, a purchase or a refund.
We are also on X: [@lumadisk](https://x.com/lumadisk). DMs are open.

## Common questions

**Is my data safe when I delete build caches?**

Yes. Folders like node_modules, /target, .next and DerivedData are fully regenerable, and your next build recreates them automatically. LumaDisk only ever lists folders that rebuild themselves.

**Does LumaDisk work on external drives?**

Yes, full support for external drives. Network volumes are supported in read-only mode.

**I bought LumaDisk on one platform. How do I get it on the other?**

A license bought on lumadisk.com covers up to 3 devices, Mac or Windows PC. Your key activates your Macs; for a Windows PC, email support@lumadisk.com with your order and we will send you a Microsoft Store code, counted toward your 3 devices. Bought on the Microsoft Store? Email us and we will send you a macOS code.

**How do I get a refund?**

Direct macOS purchases have a 14-day money-back guarantee: email support@lumadisk.com and you are refunded in full. Microsoft Store purchases are refunded by Microsoft under its own policy.
