Privacy Statement

April 2nd, 2016

Stem commitment to data privacy protection

Protecting the security and privacy of your data is important to Stem. In order for you to understand our data privacy policies, we have outlined below what data we collect on our websites, how we use that data, data security measures we employ, and with whom we may share the data.

What we request from website visitors

There are instances on our primary company websites where we ask you to provide personal information such as name, address, phone number, email address, and similar information. This type of information will improve your website experience or allow us to follow-up with you after you visit our site. Our primary company website’s contact form requires you to give us contact information, including email addresses, telephone numbers, and other personal contact information. We use customer contact information from the form to send you information about our company and its products and services. Your contact information will also be used to contact you when necessary.

What we request from remote monitoring service customers

We also have a separate customer application website which also may be accessed from our primary company website. Website visitors’ requests for information about our power monitoring service and our products which originate on this separate website are directed back to our primary company website and information is collected as we do for all information requests from the primary website, as described above. Our customer application website uses an order form for our customers to register power monitoring service received as part of power monitoring and related services from Stem. For our customers who have access to the customer application website, we may make those services available on a subscription basis. We obtain information from you when you inquire about the services we offer, when you initially register for the service, and when you purchase additional services from us.

Initial registration

If you are registering the initial customer application service which you received when you received Stem equipment, we obtain the following information from you: first and last names, a password, a valid email address as a log-in, and equipment site address. Your equipment installer may also be asked to provide certain technical information to Stem, such as a meter type, meter number, circuit breaker size, location and power and energy usage, to enable us to better provide you with the energy monitoring service; by registering for the monitoring service, you consent to Stem obtaining technical information about your energy system and its installation from your equipment installer.

Purchase of additional services

If you purchase additional services from us, in addition to the information we collect on Initial Registration, we may also obtain from you a billing address and a valid credit card or other payment information to process payment for services ordered.

Customer application information collected automatically

The customer application service itself includes an automated, Internet-based process of receiving transmissions from the Stem power monitoring equipment and other variables. This information is recorded and preserved by Stem on our company computer storage facilities, and may be accessed by you and by us whether or not you subscribe to that Service. The Stem PowerMonitor immediately begins reporting this information to Stem and will continue to do so. We retain this information indefinitely, and we may use it for any purpose, in our sole discretion, including but not limited to quality assurance, engineering performance comparisons, product improvements, and providing such information to third party utilities (and their approved vendors) as well as customer-contracted energy service companies.

Additional information requested from customers

From time to time, we also may ask you to complete surveys or answer questions regarding your satisfaction with any Stem products you have purchased and services you have received from us. We use this information to improve our services to our customer application service customers. We retain this information indefinitely. We may also ask you whether you would be willing to have information about your experience with our products and services used in our company’s marketing to other potential customers. We will ask you to separately agree to this use of some of this information, and you will have to “opt-in” to this use of your information. The information which we will use in marketing will not identify you by name or address, but will instead use only the general geographic location (city or town and state), comments from you, the physical performance data from your equipment installation which is stored on our computer storage facilities and other site-specific information as approved by you. In addition, as described above, we may use data transmitted automatically by your Stem PowerMonitor for any purpose. Any and all of this information may be aggregated with information from other customers or provided individually as an example of customer experience with our products.  For the avoidance of doubt, you should understand that Stem shares certain customer data with utilities (and their approved vendors) as well as customer-contracted energy service companies, and that such shared information may not be anonymized We retain such information indefinitely. Because our services are provided online and may be paid for by credit card (or by other means which we approve), by necessity we provide some of your information to third parties. We contract with other companies and individuals to assist us in performing certain functions on our behalf. Examples include sending postal mail and email, analyzing data, providing marketing assistance and processing credit card payments. They only have access to personal information necessary to perform their functions, but may not use it for other purposes, and must process the information in strict compliance with applicable law.

Modification of account information

Our website permits you, after you have logged on, to modify your account information, including address, email address, telephone number, and similar information.

Information collected automatically

When you access both of our websites, we may automatically (i.e., not by registration) collect non-personal data (for example, the type of Internet browser and operating system used, domain name of the website from which you came to our website, number of visits, average time spent on the page, pages viewed). We use this information to improve the visitor experience to our website. We also may use your Internet address (“Internet Protocol address” or “IP address”) and other information collected automatically to help diagnose problems with our server, and to administer our website. In addition, as described above, your Stem PowerMonitor automatically reports information to us about your energy, power, and other variables. We may use this information for any purpose, in our sole discretion, as described above.
