Privacy Policy

YepWatt doesn't ask you to sign up, and its calculators run in your browser. It uses Google Analytics to count visits and calculator use. This page explains what information is handled when you visit and who is responsible for it.

Who is responsible

YepWatt is run by Masaaki Morishita, who decides how the information described on this page is used. For questions about it, email hello@yepwatt.com.

What you enter in a calculator

The calculators run in your browser and don't send the usage, mileage, rates, and other values you enter to a server. YepWatt doesn't save them.

So you can share a comparison, those values are added to the page's address (the part after the ?). Anyone you share the address with can see them, and your browser may keep the address in its history. When you open or reload an address that holds them, or go from that page to another YepWatt page (as the address of the page you came from), Cloudflare, which hosts the site, receives the full address and may record it in its logs. Google Analytics receives the address without that part.

Visit statistics

YepWatt uses Google Analytics 4, a service from Google, to see which pages are visited and how often the calculators are used. It sets cookies on this site (_ga and _ga_ followed by an ID) that hold a random identifier for your browser for up to two years, so that repeat visits can be counted.

It records information such as the page you visit, the site that linked to it, your approximate location (country, region, and city, worked out from your IP address), your browser and its language, your operating system, device type, and screen size, the time of your visit, whether you scroll to the bottom of a page, and the links you follow to other sites, including their addresses. When a calculator shows a result, or when you switch a comparison setting such as your current plan or charging hours, it records which calculator and which setting, but not the values you entered or chose. Google Analytics doesn't log or store IP addresses.

To stop Google Analytics from collecting data in your browser, install the Google Analytics Opt-out Browser Add-on. See Google's privacy policy and how Google uses information from sites that use its services for how Google handles this information.

Hosting

YepWatt is hosted on Cloudflare. To deliver pages, report pages that fail to load, and protect the site from attacks, Cloudflare processes technical information about each request, such as your IP address, your browser, and the address requested. If Cloudflare needs to check that a visitor isn't a bot, it may set a cookie for that check. See Cloudflare's privacy policy for how it handles this information.

Email

If you email hello@yepwatt.com, Cloudflare Email Routing forwards the message to the operator's inbox. Your email address and message are used only to read and act on what you sent. They aren't sold or used for marketing.

Children

YepWatt isn't directed at children under 13 and doesn't knowingly collect personal information from them.

Your requests

To ask what information about you YepWatt holds, or to have it corrected or deleted, email hello@yepwatt.com.

Changes to this policy

When YepWatt starts or stops using a service that handles your information, this page is updated at the same time, and the date at the top changes.
