Privacy & Data
Integrity.

OffgridMath is an independent technical resource. Unlike traditional "lead-generation" calculators that require your contact information to view results, our engine operates primarily in your browser.

1. Data Collection & Usage

We do not store your specific calculation inputs (system cost, monthly bill, regional data) on our servers. All financial modeling is processed locally within your session. When you use our tools, the data stays in your browser's memory and is discarded when you close the tab.

2. Technical Auditing & Analytics

To improve our engineering models, we collect anonymous, aggregated telemetry. This includes:

• General regional coverage (State/Country)
• Calculators accessed (e.g., Solar ROI Engine)
• Technical performance data (load times, error rates)

This data is never tied to a personal identity or a specific user profile. We do not use third-party tracking pixels (such as Meta or TikTok pixels) for advertising purposes.

3. External Citations & Data Partners

Our calculators leverage public datasets from the **National Renewable Energy Laboratory (NREL)** and the **Department of Energy (DOE)**. While our site provides links to these resources, your use of external datasets is governed by their respective privacy policies.

4. Cookies & Local Storage

We use minimal cookies for essential site functionality and to remember your regional preferences (if selected). We do not use persistent tracking cookies for the purpose of targeted behavioral advertising.

Last Updated: January 08, 2026. This policy is reviewed quarterly to ensure compliance with emerging data sovereignty standards.
