Privacy Policy
Last updated: April 2026
1. Identity
This service is operated by Gadget 4 Home LLC, a company registered in the United States.
2. Data We Collect
We only collect your email address for authentication (login) purposes and to secure your account.
When you click the extension button on a supported retailer page, the extension reads product details (name, price, SKU, and image) directly from that page to add items to your estimate. This happens only when you explicitly trigger it — no browsing activity is collected passively.
If you use the right-click context menu feature, the selected text and current page URL are used to create a product entry in your estimate. This data is stored locally on your device and is never transmitted without your action.
We do not collect, store, or have access to your passwords, browsing history, or personal data from websites you visit.
3. Local & Cloud Storage
Your data — including estimates, material lists, client information, company logo, and settings — is first stored locally on your device using Chrome's secure built-in storage. If you are logged in, this data is also backed up to Supabase (hosted on AWS) with Row Level Security (RLS) enabled, ensuring that only you can access your own data. All data transmission is encrypted using HTTPS/TLS.
4. AI Privacy
Material List does not process your data with internal AI. The extension provides a pre-built prompt that you can send to your own ChatGPT account by opening a new browser tab. Your interaction with OpenAI remains entirely private and under your control. We do not store, transmit, or have access to the AI's responses.
5. No Data Sharing
We do not sell, distribute, or share your data with third parties for any purpose. Your business information remains yours.
6. Payment Processing
Subscription payments are handled securely by Stripe. We do not collect, store, or have access to your credit card or payment information.
7. Data Deletion
You may request deletion of your account and all associated data at any time by contacting support@gadget4home.com. We will permanently delete all your data within 30 days of your request.
8. Third-Party Services
The following services are used to operate Material List:
- Supabase — Authentication and encrypted cloud data storage
- Stripe — Secure payment processing
- Google Chrome Web Store — Extension distribution
- OpenAI / ChatGPT — Optional AI prompts (user-initiated, not automated)
9. Changes to This Policy
We may update this Privacy Policy from time to time. Changes will be posted on this page with an updated date. Continued use of Material List after changes constitutes acceptance of the updated policy.
