Limited Data Use

The Limited Data Use flag helps you meet your compliance needs by allowing more control over how Reddit uses certain identifiers and other data. You can use the flag for users in a state who have opted out of the sharing or selling of their data or are in compliance with your user privacy settings. For example, Reddit will act as a Service Provider under the California Consumer Privacy Act, as amended by the California Privacy Rights Act (together, “CCPA”) with respect to flagged data from users in California.

Advertisers remain responsible for complying with all applicable laws, obtaining all required consents, respecting all user opt-outs, and determining whether sending their users' data to Reddit represents the sharing or selling of data as defined by law. Advertisers are also responsible for identifying their user's location. The Limited Data Use flag is not available for Reddit Custom Audiences. Advertisers are responsible for obtaining required consent and respecting opt-outs from their users included in a customer list uploaded through Reddit Custom Audiences.

For users who have opted out of sharing or selling their data, modify the Reddit Pixel and/or Conversions API configuration to pass the Limited Data Use flag using Data Processing Mode.

Set the flag for your Pixel

Add the code snippet below during pixel initialization to configure the Limited Data Use flag. When the Pixel is initialized with data processing mode, every conversion event fired from the page will automatically include these parameters.

• dpm: Data Processing Mode for this conversion event. Currently, we only support LDU (Limited Data Use).
• dpcc: Country Code of the user. We support ISO 3166-1 alpha-2 country code.
• dprc: Region Code of the user. We support ISO 3166-2 region codes or region codes without country prefixes.

rdt('init', '{{Your Pixel ID}}', {
   dpm: "LDU", // or ["LDU"]
   dpcc: "US",
   dprc: "US-CA", // or "CA"
});

 

Set the flag for CAPI

Pass the data processing options in the user object of the CAPI request payload as instructed here. It must be passed with every conversion event for users who have opted out.

Set the flag in Google Tag Manager

1. When configuring events, select Add Data Processing Options under Tag Configuration.
2. For data processing parameters:
   • Set Mode to LDU.
   • Set Region to the region code of the user. We support ISO 3166-2 region code or the region code without country prefix.
   • Set Country to the user's country code. We support ISO 3166-1 alpha-2 country codes.

Things to know

When the LDU flag is enabled, it may impact campaign performance and limit the size of targetable audiences.
