Data & Privacy Policy


This document outlines active district m practices relevant to publisher and user data protection in relation to programmatic demand data collection.

The procedures, controls, and protections are subject to alteration as industry regulation is updated or placed into law (i.e. GDRP launching in early 2018).

district m commits to update this document as we implement industry regulation or standardization within a reasonable amount of time. Please ask your account manager if you have any specific questions.


Data collection is a necessary process of the advertising industry, allowing parties to log transactions, statistics, perform analysis, and make decisions based on this data.

That said, district m takes the privacy and protection of personal information very seriously.

Data collected for programmatic ad delivery is not PII (Personally Identifiable Information), and any data collected may only be used for aggregation, resulting in anonymization of users.

Additionally, our end-points and ad code do not contain any functionality which allows the collection of PII.

Below we share our defined data collection points.

Industry Standards

  • DAAC

district m adheres with the practices outlined by The Digital Advertising Alliance of Canada (DAAC)

  • GDRP

To address upcoming EU data protection laws and meet the requirements of the transfer of data we have ensured that our technology and platform is certified under Privacy Shield and we are taking measures to expand our European data center architecture to ensure data originating in Europe remains in Europe.

  • NAI

The primary district m advertising platform adheres to and is a member in good standing of the Network Advertising Initiative (NAI)

What We Collect

How the Data is Used

The primary use cases for our data collection include:

  • Understanding traffic patterns and ad performance
  • Reporting to publishers and advertisers

Data Sharing

In some circumstances district m may provide data it has collected to partners and service providers in order to provide, maintain, and enhance its service offering.

For example, district m may enter into data sharing agreements with third parties in order to:

  • Counter malicious activity or invalid traffic
  • Share aggregated data derived from its platforms with the intention of measuring performance
  • Provide raw log files not including device ids to 3rd parties for discrepancies investigations

district m will never share information that would compromise its own Data & Privacy Policy as outlined in this document.

Data Retention

We normally will retain data for as long as it is necessary to fulfill a legitimate business purpose or if required by law.

We may delete any data pertaining to accounts if the account is terminated, contracts expire, or a request from the Publisher is received.

district m respects your privacy and supports your right to share your information as you see fit.

Changes and Updates

The district m Data Protection for Users and Publishers policy is subject to change as the online advertising regulations change.

As such we must reserve the right to modify this Policy anytime to ensure up to date information is relayed to our Publishers.
