Privacy policy

Your calculator inputs stay in your browser.

The current site has no account system, email form, advertising tracker, affiliate tracker, or client-side analytics script. Google Search Console measures search visibility without receiving calculator inputs.

Effective August 21, 2026Public launch policy
01

Calculator data

Values entered into the calculator are held in the current browser session to produce the on-screen result. The application does not submit or save those values to a Backup Power Finder account or database.

02

Routine request data

Like ordinary hosted websites, the hosting and security providers may process request information such as IP address, browser details, requested page, time, and security signals to deliver and protect the site. Their retention and legal obligations are governed by their own systems and policies.

03

Cookies and measurement

The current application does not set analytics, advertising, or affiliate-tracking cookies and does not load a browser analytics script. Google Search Console may report aggregate search impressions, clicks, and indexed pages from Google's own search systems. It does not receive calculator entries from this site.

04

External links

Guides link to manufacturers, government agencies, and independent publishers. Their privacy practices apply after a visitor leaves this site. No current external link contains a Backup Power Finder affiliate identifier.

05

Retention and requests

Because calculator entries are not submitted, there is no calculator profile for us to retrieve or delete. Questions about routine site request data can be sent through the contact address below.

06

Policy changes

Material changes will be dated on this page. Browser analytics, email capture, user accounts, affiliate tracking, or lead sharing will not be silently added under this version of the policy.
