Calculator inputs
Calculator values are processed locally in your browser. PowerUseLab does not provide accounts or a server-side database for saving those inputs.
Vercel Web Analytics
PowerUseLab uses Vercel Web Analytics to understand aggregate traffic such as page views, referring sources, countries and device categories. PowerUseLab has not added Google Analytics or custom advertising trackers.
Location
The solar panel angle calculator can request browser geolocation only after you press “Use my location.” The page uses the returned latitude locally for the calculation and does not intentionally store the coordinates. You can always enter latitude manually instead.
External links
Some pages link to primary documentation on other websites. Those sites operate under their own privacy practices.
Future changes
If PowerUseLab introduces advertising, accounts, forms or additional analytics, this page should be updated to reflect the technologies actually used.
