Your Crosswise questions, answered

How do I access Device Map by Crosswise?

Device Map by Crosswise is distributed to clients in the form of large Gzip-compressed flat files, available in Device Pairs and/or Device Group formats.

Every Crosswise client receives a unique device map file that is customized with its own cookie IDs and generated anew every week, based on the latest available activity data.

Available device map delivery methods include direct push to the client’s server via Amazon S3, FTP or SFTP; direct pull by the client from Crosswise’s Amazon S3 bucket.

What do I need to do to integrate the device map into my systems?

Crosswise provides pure device-matching data that clients utilize within their own systems. How clients typically leverage the device map data within their system depends on how the data will be used.

For example, using the data for audience extension is relatively simple: the client runs a weekly process to add device IDs to each audience based on matches found within the device map.

For frequency capping: instead of recording each ad appearance for a single device, the client’s system will record it for all linked devices. More complex use cases may require more extensive development efforts. 

Why should I Choose Device Map by Crosswise?

  • Accuracy – In tests conducted independently by a number of clients (before they became our clients!), Device Map by Crosswise was proven to be more accurate (with greater precision and recall) than device map data available from any other source.

    These tests were conducted by evaluating various probabilistic device map alternatives against deterministic data sets used by the clients, for results that conclusively concluded that Device Map by Crosswise has greater precision, recall and scale.

    This is made possible by the combination of the company’s elite team and technological superiority (read on for details!).
  • Elite team – Crosswise employs the largest and most experienced team in the world dedicated exclusively to solving cross-device identification challenges.

    Consisting of top-notch data scientists, machine learning experts, big data analysts and software developers, the Crosswise team has the unique combination of expertise and experience required to deliver the best cross-device identification data available anywhere.
  • Technological superiority – Years of development and continuous refinement have produced multi-dimensional modeling and self-learning algorithms that dramatically outperform any other cross-device mapping approach used today.

    Additionally, Crosswise’s superior measurement methodologies deliver results which are optimized for real-world performance, a critical enabler for highly-accurate cross-device mapping.
  • Authority – Crosswise has no media, analytics or attribution business. The fact that the company is purely a data-focused company makes it a neutral, unbiased third party within the industry, intensely focused on retaining its position as the leading authority on pure device map data.

How does Crosswise collect its data?

Crosswise collects over a petabyte of device activity data every month, covering billions of devices, from multiple sources, including partnerships with publishers, mobile SDK vendors and data-licensing companies.

How does Crosswise protect consumer privacy?

There are two primary ways to match multiple devices used by an individual consumer: deterministic matching and probabilistic matching.

Deterministic matching relies on personally-identifiable details, such as a username or email address, to determine that multiple devices belong to a single user.

Because this data is personally identifiable, companies that utilize it must take extensive measures to protect the data and ensure the privacy of the users in the database.

In contrast, device maps based on probabilistic matching technologies collect and utilize only anonymous data points and have no access to any personally-identifiable information.

Crosswise is exclusively a probabilistic matching solution, and thus we do not seek, store or share any personally-identifiable information in connection with our offering.

In other words: We don’t know your name, we don’t know where you live and we don’t even know your email address.

In fact, we don’t have any information at all that identifies who you are. We just know that your Dell Inspiron laptop and your Samsung Galaxy S6 are probably used by the same person.

Having said that, we allow you to “opt out” any of your devices from our device map, if you prefer that our clients not be able to match those devices with any other devices that you use. 

What is Crosswise’s pricing structure?

Crosswise licenses its device map data to most clients for a flat monthly fee, although flexible pricing models are available for clients that require them.

Every Crosswise client receives a unique device map file that is customized with its own cookie IDs and generated anew every week, based on the latest available activity data.

It is not recommended to rely on device map data for more than one week at a time, due to the rapid pace at which it becomes obsolete.
