Privacy Policy
Last updated: August 2026
At Power Usage Calculator, transparency is core to what we do. This Privacy Policy explains how we collect, use, and safeguard your information when you use our browser-based calculators and website.
Information You Enter Into Calculators
We take a privacy-first approach to our tools. Any data you enter into our calculators—such as your electricity rate, device wattage, or home energy usage—is processed locally within your web browser. We do not transmit, log, or store your calculation inputs on our servers.
Local Storage
To improve your experience, our website may utilize standard browser mechanisms like localStorage to remember your non-identifying preferences (such as your chosen currency or region settings) so you do not have to re-enter them on subsequent visits. You can clear this data at any time via your browser settings.
Automatically Collected Information
When you visit our website, our servers and analytics providers automatically log standard technical information. This may include your IP address, browser type, device information, referring pages, and broad geographic location. This data is used solely to maintain platform performance, secure the site, and understand aggregate traffic patterns.
Cookies and Advertising
We plan to support this free platform through the use of third-party advertising services, such as Google AdSense. Once advertising is enabled, these partners may use cookies, web beacons, and similar technologies to serve personalized or non-personalized ads.
- Third party vendors, including Google, use cookies to serve ads based on a user's prior visits to your website or other websites.
- Google's use of advertising cookies enables it and its partners to serve ads to your users based on their visit to your sites and/or other sites on the Internet.
- Users may opt out of personalized advertising by visiting Ads Settings.
Consent and Privacy Rights
Depending on your jurisdiction, you may have specific rights regarding your personal data. We are committed to supporting consent-management protocols for users in the European Economic Area (EEA), the UK, and Switzerland, as well as providing applicable opt-out mechanisms for US-state privacy laws when advertising technologies are deployed.
Third-Party Services
We may use basic website analytics providers to understand how our site is used. We do not sell your personal data to third-party data brokers. Our site may also contain links to external educational resources or related tools; please note we are not responsible for the privacy practices of external websites.
Children's Privacy
Our calculators are designed for general audiences, primarily adult homeowners and consumers managing their utility bills. We do not knowingly collect personal information from children under the age of 13. If you believe we have inadvertently collected such information, please contact us so we can promptly delete it.
International Users
Power Usage Calculator is accessible globally. Please be aware that if you access our site from outside our primary hosting region, your standard connection data is transferred across borders in accordance with standard internet protocols. Privacy rights and regulations may vary by jurisdiction.

We may update this Privacy Policy periodically to reflect changes in our practices, technology, or legal requirements. The updated date at the top of this page will indicate when changes were made.
