Privacy Policy

LumDIY is a product of Megatam. Last updated 2026‑07‑26.

This policy explains what information LumDIY handles and how. LumDIY is a self-hosted smart-home hub: your devices, automations and their data live on your own hub, under your control. Our cloud service exists only to give you secure remote access and optional voice control.

Who we are

LumDIY is built and operated by Megatam. For any privacy question or request, contact us at admin@lumdiy.com.

What we collect

• Account details — the email address you use to sign in.
• Hub identifier — your hub's serial and the connection metadata needed to route your session to it (for example, the encrypted-tunnel hostname).
• Operational logs — minimal diagnostic logs (timestamps, error codes) used to keep the service reliable.

Your device names, states and commands are stored on your hub. When you use remote access, they pass through our relay in transit only — we do not build a copy of your home's device data.

Remote access

Remote access works over an encrypted tunnel between your hub and our cloud relay. The relay forwards your already-authenticated session to your hub; we do not inspect the contents of that traffic beyond what is required to route it.

Google Home

If you link your Google account, LumDIY relays Google's smart-home requests (SYNC / QUERY / EXECUTE) to your hub so you can see and control your devices with the Google Home app and Google Assistant. To keep the Home app current, LumDIY also reports device state changes to Google's HomeGraph. This exchange includes your device names, types and on/off or similar states for the devices you have chosen to expose. We do not sell your data or use it for advertising. You can disconnect at any time from the Google Home app, which revokes this access.

How we use information

We use the information above only to provide the service: to authenticate you, connect you to your hub, enable the integrations you turn on (such as Google Home), and keep the service secure and working. We do not sell personal information.

Retention

We keep account and hub-link information for as long as your account is active. Session and linking tokens are removed when they expire or when you sign out or unlink a service. You can ask us to delete your account information by contacting us.

Your choices

You can unlink Google Home at any time, and you can contact us to access or delete the account information we hold. Because your home's data lives on your hub, you remain in direct control of it.

Changes

We may update this policy as the product evolves. Material changes will be reflected here with an updated date.
