This Privacy Notice describes the ways in which Evalan B.V. and its affiliates and subsidiaries (collectively, “Wattmaestro,” “we,” “our,” and “us”) collect, receive, process, or store information, including Personal Information, in connection with our business operations (“Business Operations”), including the services we provide that reference this Privacy Notice (collectively, the “Services”). We use the term “Personal Information” to mean any information that identifies you as an individual, is about you as an individual, or is otherwise defined as personal information, personal data, or similar under applicable law.

1. Products & Services

We offer a range of hardware products and cloud-based services that together make up the Wattmaestro EMS (collectively, “Wattmaestro Products” and “Wattmaestro System”). Wattmaestro Products include Wattmaestro Hardware, the Wattmaestro Cloud, the Wattmaestro API and any other service that makes reference to this Privacy Notice.

2. Scope

This Privacy Notice applies to anyone that interacts with our Business Operations or that uses the Services (collectively, “you”). If you are interacting with our Business Operations or using the Services on behalf of a company or other legal entity (“Your Organization”), then (i) you represent and warrant that you have authority to act on behalf of, and to bind Your Organization, and (ii) for all purposes in this Privacy Notice, the term “you” means Your Organization on whose behalf you are acting.

3. Controller

The controller, i.e., the entity that is responsible for the processing of your Personal Information, and which is referred to by the term “Evalan”, “Wattmaestro”, “we”, “us” or “our” in this Privacy Notice, is Evalan B.V., an Amsterdam based company. Wattmaestro is a product developed by Evalan, and this Privacy Notice specifically applies to Products or Services of Evalan that are marketed under the name Wattmaestro (see also Section 1).

If the controller is one of our affiliates or subsidiaries (collectively, our “Affiliates”), this will be explicitly stated at the point where the data is collected or, respectively, where you have been referred to this Privacy Notice, and the full address of the respective controller will be given at the same location.

4. Collection of Information

This section describes the types of information that Wattmaestro collects. The following types of information are collected about you:

4.1 Information that You Provide

We collect information that you provide to us, when you set up an account with us, interact with us through our website, email, social media or newsletter or otherwise use our Services. Information that you may provide includes your name, email address and company name. Wattmaestro also stores information that is generated by you, for example labels you give to devices or services in our system, which is subject to this Privacy Notice as well.

4.2 Information Automatically Collected by Wattmaestro

The information that is automatically collected by Wattmaestro can vary depending on the Services you are accessing or using. We apply the principle of data minimisation, meaning that we will limit data collection to what is directly relevant and necessary to accomplish the purposes specified in Section 5.

If you are accessing or using the Wattmaestro Products, then the following will apply. The information automatically collected and/or generated and exchanged between a Wattmaestro Device and the Wattmaestro Cloud falls into three categories: Metadata, Measurement Data and Geolocation Information.

4.2.1 Metadata

The term “Metadata” means information concerning the Wattmaestro Device, independent of the Assets with which it is associated, such as the Wattmaestro Device’s ID, state or configuration. Metadata is automatically collected with each interaction between the Wattmaestro Cloud and the device.

4.2.2 Measurement Data

The term “Measurement Data” means all data (other than Metadata) collected or generated by, or transmitted to, a Wattmaestro Device, including data generated or collected by the Device’s internal or external sensors or assets, and data transmitted from your applications to your sensors or assets.

4.2.3 Geolocation Information

Wattmaestro Devices may determine their location (your “Geolocation Information”) using your device features and/or through the information provided by a third party, such as Google. We will always ask for your consent before we access Geolocation Information on your device or browser. You may revoke consent for accessing your Geolocation Information at any time, in which case GPS localization and other applicable features in your device will be disabled. Geolocation is always treated as Personal Information, regardless of whether or not it is combined with any Personal Information collected in the Wattmaestro System.

4.3 Information Automatically Collected by the Website

The following applies if you access or use the website. Wattmaestro may gather certain information automatically from the website, such as your IP address, browser type and version, operating system name and version, viewed pages on the website, pages viewed before and after accessing the website, and search terms used on the website. This information helps Wattmaestro to recognize and personalize your experience if you return to the website with the same device, and improve the website overall.

4.4 Cookies

We may gather information through the use of cookies. Prior to placing cookies on your device, we will always request your consent, with the exception of cookies that are essential for providing website features requested by you. For more information, refer to the Cookie Policy outlined in Section 7.

4.5 Anonymous Information

We may also collect, process, and use information that does not identify you or your devices, and which is neither stored on your device nor already present on your device, including information that has been made anonymous by:

i. removing identifying fields and aggregating the information with other information so that individuals cannot be re-identified, or

ii. anonymizing the information with techniques that remove or modify the identifying data so as to prevent re-identification of the anonymized information (collectively, “Anonymous Information”).

Information that meets these criteria might include, for example, demographic information, statistical information (e.g., hit counts), and general tracking information.

5. Use of Information

The information we collect about you is used for the following purposes:

5.1 Provide the Business Operations and Services

We use your Personal Information for Business Operations. This includes providing you with the Services you request or access, such as accessing or using the Services, creating and managing your user accounts, and communicating with you about our Services.

5.2 Analysis and Improvement

We may use your Personal Information and Anonymous Information to perform internal administration, auditing, operation, and troubleshooting in connection with Business Operations, including to evaluate and improve our Services, and to develop and test Services. For example, we may use Metadata for improving, measuring use of, analysing performance of, fixing errors in, providing support for, and developing Wattmaestro Hardware, the Wattmaestro Cloud, the Wattmaestro website and other Wattmaestro Products through various methods, including:

i. combining or aggregating the information collected through the device or elsewhere for generating and analysing statistics about use of the device, user demographics, traffic patterns, and other metrics, and;

ii. using anonymized data that may or may not be derived from Personal Information but does not personally identify you.

5.3 Information and Notices

If you submit your Personal Information to us, we may provide you with information about Business Operations and the Services or required notices.

Wattmaestro does not sell your Personal Information. Other than the website tools listed in Section 7, we do not share your Personal Information with other companies. If we agree with another party that it takes over part of the Services, that party may also get access to insights into the data that are necessary for that part of the Services, and we will update this Privacy Notice accordingly.

6. Storage

6.1 Security

We have implemented reasonable measures to protect your information from unauthorized access, use or disclosure. Wattmaestro maintains administrative, technical and physical safeguards designed to protect the collected information that are appropriate to the nature, size, and complexity of our Business Operations. For example:

i. Wattmaestro incorporates on-device security features, data-in-transit and data-at-rest security protections set out in the Wattmaestro datasheets, and these are designed to prevent unauthorized access to, or use of the device and the data exchanged with other applications; and

ii. communications between the Wattmaestro Cloud and Wattmaestro Devices are end-to-end encrypted and authorized via certificates. In addition, you are responsible for implementing commercially reasonable security safeguards consistent with customary industry practices to prevent unauthorized access to, or use of the Wattmaestro Device. Wattmaestro is not responsible for the security of information that you transmit over networks that Wattmaestro does not control, including the Internet and wireless networks.

iii. The complete Wattmaestro System is regularly penetration tested by an independent and specialized firm. Recommendations following from the results of these tests are implemented.

6.2 Retention

Wattmaestro retains information (including associated Personal Information) for as long as necessary to fulfil the purposes for which we collected it, in particular:

i. Device Metadata, Measurement Data and Geolocation Information that is collected automatically is kept for 90 days, unless specifically requested otherwise by you.

ii. Personal Information that is provided by you to us will generally be kept during the term of the contract and the subsequent statute of limitation period for claims arising out of the contract.
