We do not retain data for any longer than is necessary for the purposes described in this Privacy Policy. We generally retain data according to the guidelines below.
We retain each category of your Personal Information for no longer than is reasonably necessary for one or more business purposes, subject to your right to request we delete your Personal Information. Due to the nature of the Services, it is not possible to predict the length of time that we intend to retain your Personal Information. Instead, we use the following criteria to determine whether it remains reasonably necessary to retain your Personal Information for one or more disclosed business purpose(s): the purpose for which the Personal Information was collected, the level of sensitivity of the Personal Information, and the types of potential uses NK may have for the Personal Information.
When we determine that it is no longer reasonably necessary to retain your Personal Information for one or more disclosed business purpose(s) based on the above criteria, we will delete your Personal Information.
We use personal information for the following purposes:
By providing us with your email address (including by "following," "liking," or linking your account to a Service on a third-party website or network), you consent to our using the email address to send you the Service-related notices, including any notices required by law, in lieu of communication by postal mail. You also agree that we may send you notifications of activity on the Service to the email address you give us, in accordance with any applicable privacy settings. We may use your email address to send you other messages, such as newsletters, changes to features of the Service, or other information. If you do not want to receive such email messages, you may opt out at the following unsubscribe pages, depending on the brand:
We may disclose your personal information to our service providers and vendors, such as our payment processors, shipping and fulfillment providers, and sales and marketing tools.
We may also disclose, share or sell non-Personal Information specifically related to outdoor weather and environmental conditions collected by Ambient Weather Network and/or RainWise.net to business partners and third parties for weather and environmental related purposes such as forecasting, climate modeling and research. Lastly, we may also disclose non-Personal Information, aggregated with information about our other users, to our clients, business partners, merchants, advertisers, investors, potential buyers and other third parties if we deem such disclosure, in our sole discretion, to have sound business reasons or justifications.
Finally, we reserve the right to transfer information (including your Personal Information) to a third party in the event of a sale, merger, or transfer of all or substantially all of the assets of our company relating to the Services, or in the unlikely event of a bankruptcy, liquidation, or receivership of our business. We will use commercially reasonable efforts to notify you of such transfer, for example via email or by posting notice on our Site(s).
We take several measures intended to safeguard the collection, transmission and storage of the data we collect. Although we strive to employ reasonable protections for your information that are appropriate to its sensitivity, we do not guarantee or warrant the security of the information you share with us and we are not responsible for the theft, destruction, loss or inadvertent disclosure of your information or content. No system is 100% secure. Accordingly, we cannot ensure or warrant the security of any information you transmit to us or guarantee that your information on the Services may not be accessed, disclosed, altered, or destroyed by breach of any of our physical, technical, or managerial safeguards. Transmitting Personal Information is done at your own risk. Your privacy settings may also be affected by changes to the functionality of third-party providers, such as social networks. We are not responsible for the functionality or security measures of any third party. The Services use industry standard Secure Sockets Layer (SSL) technology intended to allow for the encryption of personal information and credit card numbers. The Services are registered with site identification authorities so that your browser can confirm NK's identity before any personally identifiable information is sent.
You should also be aware of the security features available to you through your internet browser. You should use a security-enabled internet browser to submit your credit card information and other Personal Information to the Services.
To protect your privacy and security, we take reasonable steps (such as requesting a unique password) to verify your identity before granting you access to your account. You are responsible for maintaining the secrecy of your unique password and account information, and for controlling access to your email communications from us, at all times.
We also collect non-Personal Information relating to the Services, that is, information that does not personally identify an individual. The non-Personal Information we collect includes how you interact with the Services, information generally collected or logged by Internet websites or Internet services when accessed or used by users, and information about your web browser or device accessing or using the Services.
Examples of the non-Personal Information we collect are:
For certain portions of our Services relating to the Ambient Weather Network and/or Rainwise.net, the Services also collect data regarding outdoor weather and environmental sensor measurements including, but not limited to, temperature, humidity, pressure, rainfall, wind speed, wind direction, solar radiation, air quality, moisture. Data collected regarding outdoor weather and environmental sensor values with other identifying or geographic location information removed are considered non-Personal Information.
As discussed in more detail below, we sometimes use cookies and other automatic information gathering technologies to gather non-Personal Information. We will not use non-Personal Information to try to identify you, and if we associate any non-Personal Information with information that personally identifies you, then we will treat it as Personal Information. Additionally, we may transform your Personal Information into non-Personal Information (including, with respect to information regarding your geographic location, by generalizing (i.e. abstracting) that location so that it can no longer identify you).
Information collected by the Services may be collected by us or one of our Service Providers (as defined below) or Online Tool Providers.
This site uses first and third-party cookies and similar technologies to process personal information for the purposes described in this Policy. Cookies are small text files placed on your device to store data that can be recalled by a web server in the same domain that placed the cookie. The text in a cookie often consists of a string of numbers and letters that uniquely identifies your device, but it can contain other information as well.

Some browsers have incorporated “Do Not Track” (DNT) features that can send a signal to the websites you visit indicating you do not wish to be tracked. Because there is not a common understanding of how to interpret the DNT signal, our websites do not currently respond to browser DNT signals. However, you may still exercise your privacy rights as described elsewhere in this Policy.
Your browser settings may allow you to automatically transmit an opt-out preference signal, such as the Global Privacy Control (GPC) signal, to online services you visit. When we detect such signal, we place a U.S. Privacy String setting in your browser so that any third party who respects that signal will not track your activity on our website. Your request to opt-out of sale/sharing will be linked to your browser identifier only and not linked to any account information because the connection between your browser and the account is not known to us. GPC is supported by certain internet browsers or as a browser extension. Find out how to enable GPC.
This site uses Google Analytics to analyze your interactions and experiences with our Services. You can find out how Google Analytics uses data here and how to opt out of Google Analytics here. For more information on how Google uses data when you use our websites, click here.

For that reason, we do not knowingly collect or solicit Personal Information from anyone under the age of 13 or knowingly allow such persons to register for the Site accounts. If you are under 13, please do not send any information about yourself to us, including your name, address, telephone number, or email address. No one under age 13 is allowed to provide any Personal Information to or on the Site.
