Privacy Policy
Last updated: September 2, 2026
Overview
Power Station Tools is built to collect as little personal data as possible. The calculators on this site run entirely in your browser — the numbers you enter (battery capacity, device wattages, hours of use) are processed locally on your device and are never transmitted to our servers or any third party as part of the calculation itself. Separately, this site uses Google Analytics 4 for aggregate traffic analytics, but only after you consent — see "Analytics" below.
Information we don't collect
We do not require an account, email address, or password to use any calculator on this site, and there are no registration or login forms anywhere on the site. We do not ask for or store the specific values you enter into the calculator. We do not sell personal data.
Local storage
To make repeat visits more convenient, this site saves a small set of your preferences (such as your last-used efficiency setting and your cookie consent choice) in your browser's local storage. This data stays on your device, is never transmitted anywhere, and can be cleared at any time through your browser's settings.
Analytics
This site uses Google Analytics 4 (Measurement ID G-FH4ZZ334E8), provided by Google, to understand aggregate, anonymized-as-possible usage of the site — for example, which pages are visited and how visitors generally navigate the site — so that we can improve it over time.
Google Analytics is not loaded until you give explicit consent through the cookie banner on this site. Before you make a choice, and if you reject analytics, no Google Analytics script is requested by your browser and no analytics cookie is set. If you accept, Google Analytics 4 is loaded and may process information such as: general technical data (browser type, device type, screen size), an approximate location derived from your IP address, the pages you view and time spent on them, and the site or search engine that referred you. We do not use Google Analytics to identify you by name, and we do not combine analytics data with any other personal information, because we don't hold any.
For this analytics processing, Google acts as a separate data processor/provider operating under its own privacy policy and terms; Google's own documentation describes how it handles Google Analytics data.
Legal basis: this analytics processing relies on your freely given, informed consent, collected through the cookie/consent banner described in our Cookie Policy — no analytics cookie is set and no Google Analytics request is made until you accept. You are free to reject analytics, and you can change your choice at any time using the "Cookie Preferences" link in the site footer.
Advertising
Google AdSense is not currently active on this site, and no advertising cookies or scripts are loaded. If advertising is enabled in the future, this Privacy Policy — and the cookie consent mechanism — will be reviewed and updated beforehand to describe what is collected and how to opt out where applicable.
Third-party links
This site may link to external resources or, in the future, third-party product or affiliate pages. We are not responsible for the privacy practices of external sites — please review their own policies.
Your data protection rights
Depending on where you live, applicable data protection law (such as the GDPR for users in the EU/EEA/UK, or similar frameworks elsewhere) may give you rights over any personal data processed about you, including the right to: request access to your data; request correction or deletion of your data; request restriction of, or object to, processing; request data portability; and withdraw consent at any time (for example, by rejecting or later revoking analytics consent via "Cookie Preferences"), without affecting the lawfulness of processing carried out before withdrawal. You may also have the right to lodge a complaint with your local data protection supervisory authority.
To exercise any of these rights, or with any question about this policy, contact us at hello@powerstationtools.com.
Children's privacy
This site is not directed at children and does not knowingly collect personal information from anyone.
Changes to this policy
We may update this Privacy Policy from time to time — for example, before enabling advertising. Material changes will be reflected by updating the "Last updated" date above.
