Privacy

There are no accounts, no sign-in and no tracking pixels. Page views are counted, without cookies, as described below. The site sets no cookies. Two values are stored in your browser’s local storage, both because you chose something, and neither ever leaves your device.

Nothing you type into the calculators is stored. The figures are computed from published tariff data, and the inputs live in the page’s address so a result can be shared — which also means they appear in the address bar, so treat a shared link as public.

Two keys in local storage, and nothing else:

• wattclear-theme — whether you chose the light or dark theme. Set only when you use the theme control.
• wattclear-privacy-choice — your advertising privacy choice, described below. Set only when you make one.

Both are local storage rather than cookies, which means they are never transmitted with a request. Clearing your browser’s site data removes them, and the site works without them.

No analytics service is installed beyond the page-view counter described below — not Google Analytics, not an advertising measurement tag. There is no advertising or measurement pixel. No profile of you is built by WattClear, because there is nothing to build one from.

The site does not ask for your address, your utility account, or a copy of a bill. The bill analyser works from figures you type in, and those are never sent anywhere but the computation that answers you.

Like any website, the hosting provider records ordinary server logs — the requested URL, the time, an IP address and a user agent — as a normal part of serving a request. Those are the host’s records, retained under its own policy, and are not used here for any analytical purpose.

The site counts page views with Cloudflare Web Analytics, from Cloudflare, the company that hosts it. Its script sets no cookies and reads or writes nothing in your browser — no local storage, no session storage — and Cloudflare says it does not fingerprint a visitor by IP address, browser or anything else. It receives your IP address, as any request does, and discards it at the data centre that received it rather than storing it.

With each page view the script sends the page’s address, the page you came from, and how long the page took to load and draw, measured by your browser. Cloudflare’s own account lists what it collects and describes how it handles it.

A page opened with anything after a “?” in its address — a calculator result, a shared link, a ZIP code lookup — is not counted at all, so the figures you type, the tariff you pick and a ZIP code you look up are never sent. The script loads only after the page has finished loading, and WattClear sees totals — page views, visits, referring sites, countries, devices — and nothing about any one visitor.

No advertising is running yet. No ad script loads today. When advertising is switched on it will be served by Google AdSense, and from then the following applies:

Third-party vendors, including Google, use cookies to serve ads based on your prior visits to this website or other websites.

Google’s use of advertising cookies enables it and its partners to serve ads to you based on your visit to this site and/or other sites on the Internet.

You can opt out of personalised advertising in Google’s Ads Settings, or opt out of some third-party vendors’ use of cookies for personalised advertising at www.aboutads.info. How Google uses information from sites that use its services is set out in Google’s own explanation.

How consent works when advertising runs. Visitors in the European Economic Area, the United Kingdom and Switzerland are shown Google’s consent message, from a consent platform certified under the IAB Transparency and Consent Framework, and are shown personalised ads only if they agree. Google decides who sees that message; this site does not guess your location from an IP address.

Everywhere else advertising runs by default, and you can opt out of the sale or sharing of your personal information with the control in the footer. Once you do, every ad request on the page is marked for restricted data processing, under which Google serves only non-personalised ads — chosen from the page you are reading and a coarse location, not from your browsing elsewhere. A Global Privacy Control signal is treated the same way.

The footer carries a control for opting out of the sale or sharing of personal information, in the sense several US state privacy laws use those words. Your choice is recorded on your device and signalled to any advertising code through the interfaces the industry reads.

Global Privacy Control is honoured. If your browser sends a GPC signal, it is treated as an opt-out without your having to set one here.

Because there are no accounts, there is no profile to request, correct or delete. A request to access or delete personal information would find nothing held by WattClear, which is the point of collecting none.

The tariff, consumption and geographic data is public-record material from US federal sources, not from visitors. It concerns utilities and published rate filings rather than people. The methodology page names every source, its licence, and when it was retrieved.

This is a reference site about household electricity costs. It is not directed at children, and it knowingly collects nothing from anyone, of any age.

If this policy changes materially the date at the top changes with it. Past versions are in the repository’s history rather than being quietly overwritten.
