We don't ask you to create an account or provide personal information to use our calculators. You can use every tool on this site without telling us your name, email, or anything else.
We do collect anonymous usage data through cookies and similar technologies, which we explain below.
We use the following cookies and tracking technologies:
We use Google Analytics 4 to understand how people use the site: which pages are visited, how long people stay, and which calculators are most popular. Google Analytics uses cookies to distinguish between visitors. The data is aggregated and anonymous. We can't identify individual users from it. Google Analytics may transfer data to servers in the United States.
We display advertisements through Google AdSense. Google and its advertising partners use cookies to serve ads based on your prior visits to this site and other sites on the internet. These cookies allow Google and its partners to serve relevant advertisements to you.

In practice, because we don't collect personal information beyond anonymous analytics cookies, there's very little data to access or delete. But if you have concerns, email us at hello@energycalculator.uk and we'll respond within 30 days.
Google Analytics data is retained for 14 months, after which it's automatically deleted. We don't store any personal data on our own servers. Calculation inputs (wattage, hours, etc.) are processed entirely in your browser and never sent to us.
This site is not directed at children under 13. We don't knowingly collect data from children. If you believe a child has somehow provided personal data to us, contact us and we'll delete it immediately.
We may update this policy if we add new tools or change how we use data. The "last updated" date at the top will always reflect the most recent version. We won't make material changes without updating this page.
