We respect your right to data privacy and will never share your personal information. This Privacy & Cookies Policy describes who we are, what information we might collect about you, how we might use that information, who may access that information, and how you can manage your preferences.

Who we are + how to contact us

WattTime is an environmental tech nonprofit that empowers all people, companies, policymakers, and countries to supercharge their emissions reductions and accelerate a cleaner energy future today. Founded by UC Berkeley researchers, we develop data-driven tools and policies that increase environmental and social good.

If you have questions about this policy, please email or contact us in writing via mail at WattTime | 490 43rd Street, Unit 221 | Oakland, CA 94609 USA.

Personal data we DO collect

We sometimes collect your personal information in order to provide and improve our solutions and services. That information might include:

Information you give us: In the course of submitting newsletter subscription, contact, tech support, donation, and/or other web forms; through direct correspondence with WattTime team members; and/or other activities, you may provide to us and we may collect from you personal information potentially including: name, title, organization, email address, phone number, and mailing address.

Automatic information: In the process of browsing the website, opening and clicking links in emails from us, and other activities, we automatically receive and store information that helps us improve our content, solutions, and services, such as whether you’ve opened an email, which links you may have clicked in that email, and which pages of our website are most popular.

Personal data we DON’T collect

To analyze our website traffic and deliver better content to you, we use the cookie-less web analytics service, Matomo, which anonymizes all users (including their IP address) and then aggregates that information.

Your activity browsing this website is NOT tracked on an individual level, nor is it connected to or in any way affiliated with information you might supply to us (such as contacting our team via the website contact form).

If you would like to opt out of Matomo stats altogether, you can do so here:

You may choose to prevent this website from aggregating and analyzing the actions you take here. Doing so will protect your privacy, but will also prevent the owner from learning from your actions and creating a better experience for you and other users.

Who has access to your information

We will never sell, lease, or otherwise share your personal information with unaffiliated, third-party individuals and organizations. WattTime will only use your personal information to deliver solutions, services, and communications. In addition to Matomo for anonymized and aggregate website analytics, we also use the following third-party services:
  • Mailchimp: We use Mailchimp for most of our marketing and other email communications. You can learn more about Mailchimp’s data privacy and security practices here.
  • Donorbox: We use Donorbox to handle donations submitted on the Support Our Work page. You can learn more about Donorbox’s data privacy and security practices here.
  • Trakstar Hire: We use Trakstar to handle the job openings posted on the Careers page. You can learn more about Trakstar’s data privacy and security practices here.

Other details

If you are a WattTime partner who accesses our data solutions and API, a separate terms & conditions agreement governs that data. If you have any other questions about this policy, please email
