Cookie Policy
Last updated: September 2, 2026
Local storage (not a cookie)
Power Station Tools's calculators run entirely in your browser using local storage — not cookies — to remember a small set of preferences, such as your last-used efficiency setting and your cookie consent choice. This data stays on your device and is never sent to our servers.
Analytics: Google Analytics 4 (only after you consent)
This site uses Google Analytics 4, which relies on cookies and similar technologies (set by Google's own script) to distinguish visitors and sessions and measure aggregate site usage. Google Analytics is not loaded, and no analytics cookie is set, until you click "Accept" on the cookie consent banner. Until you accept, and if you reject or simply close the banner, no request is made to Google's analytics servers and no analytics cookie is written.
Once loaded, Google Analytics 4 sets its own cookies directly via Google's script — we don't set these ourselves and don't control their exact names, which Google may change. Google's own documentation currently describes these as including cookies such as _ga and _ga_<container-id>, used to distinguish users and sessions; see Google's cookie documentation for the current, authoritative list.
Advertising cookies
Google AdSense is not currently active on this site, so no advertising cookies are set. If AdSense is enabled in the future, this Cookie Policy and the consent banner will be updated beforehand to reflect that change and to let you accept or reject advertising cookies separately.
What happens when you accept or reject
- If you accept: Google Analytics 4 is loaded, its cookies are set, and aggregate usage data (such as pages viewed) is collected as described in our Privacy Policy.
- If you reject: Google Analytics 4 is never loaded and no analytics cookie is set. Only the local storage preferences described above (which are not cookies) remain.
- Changing your mind: you can accept or reject analytics again at any time using the "Cookie Preferences" link in the site footer, which reopens the consent banner without affecting your ability to use the calculators.
Managing cookies
Most browsers also let you view, delete, and block cookies directly through their settings. Blocking cookies will not affect the core calculators on this site, which do not require cookies to function.
