SPARK NEC Assistant — Last updated July 7, 2026
SPARK (“we,” “our,” or “the app”) is an AI-powered electrical code compliance tool for apprentice and journeyman electricians. This policy explains what data we collect, how we use it, and who we share it with.
Account information: When you sign in with Apple or Google, we receive your account user ID, name (if provided), and email address (if provided). This is stored on our server to identify your account.
Role and preferences: Your selected role (apprentice or journeyman), apprentice year, and default job type are stored to personalize your experience.
Photos: When you use Inspect or Advisor mode, the photo you capture or select from your photo library is sent to our server. Photos are stored alongside inspection reports for review by your linked journeyman.
Helmet voice queries and images: If you pair a SPARK helmet, your spoken questions are transcribed on the helmet and the transcript — along with an image from the helmet’s camera, when relevant — is sent to our server over your phone, answered, and stored with your inspection history. The phone app itself never records audio.
Voice-commanded photos: Saying “take a picture” (or “document this”) to a paired helmet captures an image from the helmet’s camera and saves it to your inspection history the same way, without an AI answer. Saying “send this to my foreman” or “ping my foreman” flags the item so your linked journeyman or foreman can see it in their review view.
Wi-Fi setup: If you use the app to connect your helmet to a Wi-Fi network, the network name and password you enter are sent directly to your helmet over Bluetooth. They are never transmitted to or stored on our servers.
Inspection reports: AI-generated analysis results, NEC citations, verdicts, and any corrections made by journeymen are stored on our server.
Usage data: We collect usage analytics — which features and screens you use, session frequency, and inspection counts — along with your device model, OS version, and app version, linked to your account ID, using PostHog (see Section 2). We do not collect location data or browsing history.
Google Gemini API: Your photos, helmet images, and voice query transcripts are sent to Google’s Generative Language API (generativelanguage.googleapis.com) for AI-powered analysis. Specifically:
PostHog (analytics): Usage analytics and device information, linked to your account ID, are processed by PostHog Inc. on US-based servers. PostHog acts as our service provider; this data is not used for advertising and is not sold or shared with data brokers.
Railway (hosting): Our server and stored data run on Railway infrastructure (see Section 5).
Apple / Google sign-in: Authentication is handled by the provider you choose; we receive only the account details described in Section 1.
No other third-party services receive your photos or personal data. We do not share data with advertisers.
We use your data to:

SPARK is designed for professional electricians. We do not knowingly collect data from anyone under 16. If you believe we have collected data from a minor, please contact us immediately.
We may update this policy as SPARK evolves. Material changes will be communicated through the app. Continued use after changes constitutes acceptance.
