Privacy Policy

Zenreach is now operating as Adentro.

Effective Date: January 13, 2021


This is the Privacy Policy of Zenreach, Inc. (“Zenreach,” “we,” “us,” or “our”), doing business as Adentro. We give our clients tools to manage their own Wi-Fi service and to understand and communicate with their customers. This Privacy Policy covers Zenreach’s handling of two categories of information:

1. Information we receive in connection with our relationship with our clients, such as the email addresses their customers (“End Users”) supply when signing up for our Wi-Fi with enhanced marketing features (the “Enhanced Wi-Fi”) or visiting our clients’ websites, as well as certain information collected in connection with the Enhanced Wi-Fi routers; and

2. Information collected from visitors to Zenreach’s own website,

Each of those two categories has its own section below. Following those sections is a third section containing general information about our privacy practices, as well as your opt-out options and details about exercising your rights. This Privacy Policy does not address our clients’ own privacy practices.

1. Privacy Practices for Information We Receive in Connection with Our Relationship with Our Clients

Information Collected

In an expanding number of cities, we provide our clients (restaurants, stores and other businesses) with wireless routers that let them share their Internet connection with people around their location. Our clients’ End Users in the European Union and California can elect to just access the Internet via the client’s Wi-Fi, or they can voluntarily opt into the Enhanced Wi-Fi. For those who do not opt into the Enhanced Wi-Fi, we collect limited technical information that does not identify the End User and process such information to provide and troubleshoot Wi-Fi access. We retain such technical information collected for no more than thirty days. For those End Users who register for the Enhanced Wi-Fi, we receive and maintain the unique MAC address of your wireless device and the nearby Wi-Fi routers to provide you with the enhanced marketing features. To sign up for Enhanced Wi-Fi, an End User must (1) submit basic contact information, such as an email address or mobile phone number, and (2) agree to terms and acknowledge our privacy practices. The End User may choose to enter additional information, such as their month and day of birth.

After an End User signs up for Enhanced Wi-Fi, we associate their email address and other personal data with their device’s MAC address and any location history we may later gather for that device’s MAC address. Later, when the End User’s device returns to this client location or enters the Wi-Fi range of another Zenreach router (of any Zenreach client), we automatically recognize the device and record the visit in our record for that device, which enables us to provide you enhanced marketing features, such as coupons for businesses you already patronize. End Users may opt out of Enhanced Wi-Fi at any time, and End Users may also request that we delete their personal data at any time. Please see the sections below entitled, “Opt-Out and Privacy Rights” and “Your Legal Rights Under Local Laws” for more information. We also may record information about whether and when the End User registered for Enhanced Wi-Fi has used the Internet, but Zenreach does not review or record the actual Wi-Fi traffic (such as the content of emails sent through the Wi-Fi or the URLs of web pages visited).

In some cases, we may operate a portion of our client’s website, such as when we manage an email list sign-up form for them (in addition to or instead of the Wi-Fi-based signup form). On our clients’ websites, and in the signup and login pages for our Enhanced Wi-Fi, we and our third-party service providers, including Google Analytics, may use cookies, web beacons, and other automated technologies to collect information about the computers or other devices used to access the Enhanced Wi-Fi. As described further below, we may collect and analyze information such as browser type, ISP, operating system, access time, IP address, device type, unique device identifiers, and the web pages from which visitors arrive at the website. We act as a data processor for personal data we access when we operate a portion of our clients’ websites.

In addition to the above, our clients may provide us with personal data (usually about their current and potential customers), such as customer contact or point-of-sale information. As permitted by applicable law, we may also collect information from third-party sources (such as social networking platforms). We may enhance the data we receive from or on behalf of a particular client with data that we receive from other data sources or that we have inferred or modeled ourselves.

Cookies and Other Technologies:

We and our third-party service providers may use cookies, clear GIFs, pixel tags, and other technologies that help us better understand user behavior, personalize preferences, perform research and analytics, and improve the products and services we provide. We or our third-party service providers also may use certain of these technologies in emails to end users, to help us track email response rates, identify when our emails are viewed, and track whether our emails are forwarded. You can choose to accept or decline certain cookies. Most web browsers automatically accept cookies, but your browser may allow you to modify your browser settings to decline certain cookies if you prefer. If you disable cookies, you may be prevented from accessing or taking full advantage of the Enhanced Wi-Fi or our clients’ websites.

Online Analytics:

We may use third-party web analytics services, such as those of Google Analytics. These service providers use cookies and other technologies described in this Privacy Policy to help us analyze how users use our website and the Enhanced Wi-Fi. The information collected by the technology will be disclosed to or collected directly by these service providers. To prevent Google Analytics from using information for analytics, a user may install the Google Analytics Opt-Out Browser Add-on by clicking here.

Tailored Advertising:

Third parties such as Facebook may also use cookies, web beacons or other tracking technologies on your computer or device to collect information about your access to or use of our client’s website or Enhanced Wi-Fi, or elsewhere on the Internet, to (i) inform, optimize, and serve marketing content based on your access to or use of a website or the Enhanced Wi-Fi and (ii) report how our marketing content impressions, other uses of marketing services, and interactions with these marketing impressions and marketing services are related to visits to our establishment(s), access to, or use of websites or the Enhanced Wi-Fi. We may also allow other third parties (e.g., ad networks and ad servers such as Google Analytics, DoubleClick and others) to serve tailored marketing to you through our clients’ websites or Enhanced Wi-Fi, and to access their own cookies or other tracking technologies on your computer, mobile phone, or other device you use to access the Enhanced Wi-Fi. We neither have access to, nor does this Policy govern, the use of cookies or other tracking technologies that may be placed on your computer, mobile phone, or other device by non-affiliated, third-party ad technology, ad servers, ad networks or any other non-affiliated third parties. Those parties that use these technologies may offer you a way to opt out of targeted advertising as described below. Cookies may be associated with de-identified data linked to or derived from data you voluntarily have submitted to us (e.g., your email address) that we may share with a service provider in hashed, non-human readable form.

If you are interested in more information about tailored browser advertising and how you can generally control certain cookies from being put on your device to deliver tailored advertising, you may visit the Network Advertising Initiative’s Consumer Opt-Out Link, the Digital Advertising Alliance’s Consumer Opt-Out Link or the European Interactive Digital Advertising Alliance Opt-Out Link to opt out of receiving tailored advertising from companies that participate in those programs. To opt out of Google Analytics for Display Advertising or customize Google Display Network ads, you can visit the Google Ads Settings page. Please note that you will still receive advertising content even if you opt out of tailored advertising. Also, we do not control the four opt-out links above and are not responsible for any choices you make using these mechanisms or the continued availability or accuracy of these mechanisms. If your browser is configured to reject cookies when you visit an opt-out page, or you subsequently erase your cookies, use a different computer or change web browsers, your opt-out may no longer be effective. Additional information is available on the websites accessible by the above links.

Uses of Information

We use the information described above (sometimes in combination with other information we obtain) for the following business and commercial purposes:

3. Additional Information about Privacy Practices

Disclosures of Information

To Our Clients. When we collect information for or on behalf of a client, we may share certain information with that client to help our clients learn more about their current customers, and to assist them (or others) in identifying trends, inferences, affinities or patterns among customers (whether those customers are identified, de-identified or aggregated). We also share anonymized data (e.g. when coffee shops are the busiest) among our clients to assist them in communications and marketing activities (such as to provide content recommendations and optimization, ad targeting, and other promotional activities to you).

Affiliates. We may share information with our affiliates who provide services to us.

To Agents & Contractors. We may share information with third parties that help us operate our business and provide our services, such as contractors that provide us with technology, services, data or content (e.g., a hosting provider). 

For Legal Reasons. We may share information when we believe that doing so is appropriate to comply with the law; enforce or apply our agreements; or protect the rights, property, or safety of Zenreach, our clients, our employees, or others. This may include exchanging information with other companies and organizations for fraud protection and credit risk reduction.

Changes in the Structure or Ownership of the Company or its Assets. We may transfer the information we hold in the event we sell or transfer all or a portion of our business or assets (such as in connection with a merger, acquisition, reorganization, dissolution or liquidation) or take steps in anticipation of such a transaction.

Direct Collection by Third Parties. In some cases, we may arrange for a third party to collect information directly from individuals, such as if we help a client install embedded content or tools on their website or app (or when we do this on our own website), such as embedded videos, embedded social network buttons or automated advertising technology. These third parties may collect information directly (for example, when they record a user’s “Like” of something). Such providers’ handling of the information is subject to their own privacy policies, terms and practices and is not covered by this Privacy Policy.

Aggregated or De-identified Information. We may share aggregated or de-identified data without restriction.

At a Client’s Request. At the request of a client, we may also make additional disclosures of information we hold for that client.
