1. Our Platform:

Our Platform helps clients collect, manage and distribute their data to better recognize, understand, and market to their consumers.

The Signal Tag Manager Platform (Data Hub) enables our clients to: 

  • Implement third party tags from marketing and analytics partners on their website(s).
  • Track online data from digital applications such as websites, mobile apps, and digital advertising for better cross-channel measurement, advertising, and marketing activities.
  • Activate their audience data to their endpoint partners throughout the digital ecosystem.

2. Information we collect and sources:

Signal’s Tag Manager automatically collects the following categories of information about you (“Tag Data”):

Identifiers: When a tag managed through Tag Manager fires, we collect identifiers in the form of Cookie IDs passively from your device.

Internet or other electronic network activity information: When a tag managed through Tag Manager fires, we collect aggregated data about tag firing, passively from your device. We may also collect standard HTTP request logs passively from your device; HTTP request logs are deleted within 14 days. In addition, we may collect behavior activity such as when a click or purchase happens.

Signal customers may use Signal to process certain customer data; however, this information is not available to Signal.

3. How we collect usage data

We and/or our partners use cookies and similar standard web technologies to collect Tag Data, including the following:

Cookies and Local Storage. Cookies and local storage are data files placed within a browser on a device when it is used to visit a website. Both cookies and local storage can be used to store digital identifiers whenever you visit one of our client’s websites. Most browsers provide you with the ability to disable or decline most types of cookies and local storage.

Web Beacons. Web Beacons are small graphic images or other web programming code (also known as “1×1 GIFs” or “clear GIFs”) that are included in our clients’ websites or emails.

Embedded Scripts. An embedded script is programming code that is designed to collect information about your interactions with a website. The code is temporarily downloaded onto your device from our web server, is active only while you are connected to the website, and is deactivated or deleted thereafter.

SDKs and APIs. SDKS and APIs are programming codes that collect information about your interactions with mobile apps and websites. This code is installed on a device, typically within our clients’ applications that you choose to download onto your mobile device.

4. Purpose and use of your information

Signal uses data collected for the Tag Manager Platform for the following purposes:

  • To provide the Platform to our Clients: Generally, we use the information we collect about you to help our clients to better understand their customers and prospective customers and help our clients better target and customize marketing, websites and content, and measure and optimize the performance of their marketing.
  • To build various inferenced data segments (“Data Segments”): We may use the information we collect to help our clients build Data Segments based on a user’s site activity such as a webpage visit to a specific product or adding an item to a cart. Our clients may use these segments to better understand their customers’ journey on their website(s). The Data Segments also may be associated with anonymized IDs or cookies.
  • Behavioral Advertising: We work with clients and partners that use anonymized IDs and associate them with cookies and/or other digital identifiers such as hashed email addresses to help them target ads to you that are based on your online activity on our clients’ websites or apps.
  • Cross-device tracking: We (or partners and clients with whom we work) may use the information we collect to try to locate the same unique users across multiple browsers or devices (such as smartphones or tablets), or work with providers that do this, in order to enable our clients to better target ad campaigns to common sets of users. For instance, a brand may wish to target customers that it usually recognizes on web browsers through mobile apps.
  • As we believe to be necessary or appropriate: We may use the information we collect (a) under applicable law, including laws outside your country of residence; (b) to comply with legal process; (c) to respond to requests from public and government authorities including public and government authorities outside your country of residence; (d) to enforce our terms and conditions; (e) to protect our operations or those of any of our affiliates; (f) to protect our rights, privacy, safety or property, and/or that of our affiliates, you or others; and (g) to allow us to pursue available remedies or limit the damages that we may sustain.
  • To evaluate, operate or improve the Platform.

  • Third Parties Providing Services on Our Behalf or on Behalf of Our Clients. We may sell/share Tag Data with third parties who provide services to our clients. These entities may have access to information, including personal information, in order to perform services for us or on behalf of our clients. Examples include: assist with technical, operational, or hosting support, software and security services, or to enable other services that we offer.

Mobile device operating systems such as Apple iOS or Google Play Services provide mechanisms that allow users to opt out of the use of information about their usage of mobile apps to deliver targeted ads based on their interests.
