This privacy policy also describes C WIRE’ data practices relating to information C WIRE collects through its website, and not only pertains to C WIRE’ Services. Your use of the Services is also governed by the Terms of Use.As used herein, “personal data” means any information that identifies, relates to, describes, is reasonably capable of being associated with, or could reasonably be linked, directly or indirectly, with a particular C WIRE customer or consumer or his or her household.Please note that we may update or change this privacy policy. If we make any material changes we will notify you by means of a notice on our website prior to the change becoming effective.

2. User Identification

We do not collect or process information related to (i) name, user address, place of work, date of birth, email address, or phone number, (ii) hardware-based identifiers such as UDID or MAC Address or (iii) sensitive targeting categories as defined by the European Interactive Digital Advertising Alliance (EDAA) in the European Economic Area (EEA) and under other applicable law (e.g. religion, political opinion, health).

In order to deliver ads, C WIRE uses the following 3 methods to identify users depending on the device they use, whether they access our Services on web or mobile, and operating system:

  • Cookie-based identification

C WIRE drops a cookie on the user browser. Cookies are alphanumeric identifiers that are created on your device through your web browser for record-keeping purposes. Cookies are used to identify a user and store a randomly generated identifier to identify his or her browser across visits.

  • Cookie-less identification

For browsers setup to not allow cookies to be dropped, C WIRE uses an identification methodology based on IP address non-reversible encryption, browser, and device characteristics. This method allows C WIRE to identify a user in order to provide the same level of services, such as reporting and targeting information to users, segmenting users, and capping the number of times the same ad is shown to the same user.

  • Mobile Applications identification

C WIRE uses its software development kit (“SDK”) technology to identify your advertising ID for mobile applications. For Google Android operating system, we use the Google Advertising ID and for Apple iOS the IDFA.

We do not collect information about you directly, but we collect data through our web tags on publisher web pages, or through our SDK within publisher mobile apps. We also automatically collect the information listed below about your use of our Services through tracking technologies such as cookies, pixel tags, beacons, and embedded scripts. These tools help us collect and measure session information, time spent on certain pages, and page interaction information.

3. Automatically Collected Information

  • Identifiers: IP address, advertising ID for Apps.
  • Internet or other electronic network activity information: Page URL, Browser Information (e.g. Browser name and version), Device Information (e.g. Device type, OS), Network carrier information (e.g. Wifi, 4G or Wired connection), Mobile application information (e.g. Application name or IDFA), User Interactions with C WIRE Ad Formats
  • Geolocation Information:
  • Non-Precise Geolocation data: On web and web mobile, we collect non-precise location information at the country and/or city level that are derived from user IP Address.
  • Precise Geolocation data: On mobile apps, when a user opts-in for Geo Location on the publisher’s app, precise user geolocation (latitude / longitude) might be transferred to C WIRE’ SDK by the mobile app, but this data is not stored by C WIRE.
