Privacy, plainly.
November 4, 2026
HearthGrid is a public development-concept website from TSG Global, Inc. This page explains the information used when you explore the presentation.
The interactive concept
The energy calculator runs in your browser. Its input values are not sent to our server. The partnership preview does not collect or submit personal information. Links to other websites are governed by those websites’ privacy practices.
Optional analytics
When configured and with your permission, Google Analytics 4 helps us understand visits, and Microsoft Clarity helps us understand interactions through usage analysis and session replay. These services can receive device, browser, network and interaction data and use cookies or similar identifiers. Clarity is configured with Strict masking. Calculator inputs are also marked for masking.
We do not load these services until you choose to allow analytics. If the services have not been configured, no analytics tag is loaded. A Global Privacy Control signal is respected. Your preference is stored locally in your browser.
You can decline or withdraw consent here. Withdrawing consent reloads the page to stop loaded analytics scripts and removes identifiable first-party analytics cookies where the browser permits. You can also remove site data in your browser settings.
Hosting and delivery
Heroku hosts this website. Hosting systems process technical request information, such as IP addresses, request URLs and timestamps, to deliver pages, operate the service and diagnose errors. The site serves its own fonts, model code and narration audio.
AI-generated narration
The optional presentation uses prerecorded AI-generated narration created with ElevenLabs. Pressing Play downloads the audio from this site; it does not send your microphone audio to a voice service. We do not request microphone access.
