Privacy Policy

1. Information We Do Not Collect

GridSpecLab is a static, educational reference site. We do not require you to create an account, we do not require a credit card, and we do not maintain a user database of sensitive personal data.

Our interactive engineering calculators (such as the Runtime Sizing Calculator, Sump Pump LRA Estimator, and Refrigerator Sizer) process all calculations locally in your web browser. None of your input wattages or appliance selections are stored on our servers.

2. Information We Automatically Collect

Like most websites, when you visit GridSpecLab, our hosting infrastructure and analytics providers may log standard non-personally identifiable technical information, including:

• Browser type and version
• Operating system and device category (desktop, tablet, mobile)
• Referring website URL and exit pages
• Time, date, and duration of pages visited
• General geographic region (country or city level, without precise GPS tracking)

We use this aggregated data solely to monitor site performance, troubleshoot broken links, and optimize our calculators for mobile devices.

3. Cookies & Third-Party Technologies

We may use minimal session cookies or local browser storage to retain preferences (such as calculator units or theme settings).

When you click on outbound retailer links (such as Amazon.com), the destination site may place a tracking cookie on your device to attribute referral sales in accordance with their respective privacy policies. We do not control third-party cookies placed by external retailers.

4. Third-Party Links

GridSpecLab contains links to third-party websites, including manufacturer support manuals, Amazon store pages, and external technical resources. We are not responsible for the privacy practices, content, or data protection policies of those external websites. We encourage you to review the privacy policies of any site you visit.

5. Children's Privacy

Our site is directed to general adult audiences interested in home power backup, electrical systems, and emergency preparedness. We do not knowingly collect personal information from children under the age of 13.
