Privacy Policy
Last updated: September 1, 2026
Overview
Power Station Tools is built to work without collecting personal data. 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.
Information we don't collect
We do not require an account, email address, or password to use any calculator on this site. We do not ask for or store the specific values you enter into the calculator. We do not sell personal data, because we don't collect it in the first place.
Local storage
To make repeat visits more convenient, this site may save a small set of your preferences (such as your last-used efficiency setting) 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
We may in the future use a privacy-conscious analytics tool (such as Google Analytics) to understand aggregate traffic patterns — for example, which pages are most visited — in order to improve the site. Where used, analytics tools may collect standard technical data such as approximate location, device/browser type, and pages visited, generally via cookies or similar technology. No analytics integration is currently active; this policy will be updated with specifics before any such tool goes live.
Advertising
We plan to monetize this site with advertising (such as Google AdSense) in the future. Ad networks typically use cookies to serve relevant ads and may collect data as described in their own privacy policies. No advertising is currently active on this site. This policy will be updated with details before ads are enabled, including information on 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.
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. Material changes will be reflected by updating the "Last updated" date above.
