These Reddit Business Tool Terms (“Business Tool Terms”) govern your access to and use of tools that enable you to share data with us, or enable us to access data, for measurement, targeting, and other advertising purposes. These tools include the Reddit Pixel, Reddit’s advertising APIs, postback URLs, SDKs, data clean rooms, Reddit Custom Audiences, and similar tools provided by third parties in connection with your use of the Ads Services (collectively, “Business Tools”). These Business Tool Terms are incorporated into the Reddit Advertising Services Agreement and are subject to all terms and conditions, policies, rules, and other provisions in the Ads Services Terms. Any terms that are capitalized but not defined in these Business Tool Terms are defined in the Ads Services Terms.

YOU ARE REQUIRED TO USE BINDING INDIVIDUAL ARBITRATION TO RESOLVE ANY DISPUTES RATHER THAN JURY TRIALS OR CLASS ACTION. UNLESS YOU OPT-OUT PURSUANT TO SECTION 18 OF THE REDDIT ADVERTISING SERVICES AGREEMENT, YOU AND REDDIT WAIVE ANY RIGHT TO RESOLVE DISPUTES IN A TRIAL, CLASS-ACTION LAWSUIT OR CLASS-WIDE ARBITRATION.

1. Your Use of the Business Tools and Sharing of Business Tool Data with Reddit

When you use the Business Tools, you may share with us or enable us to access Event Data and Customer List Data (each defined below) (collectively, “Business Tool Data”).

• “Event Data” means data about users of your websites, hosted applications, mobile applications, and other surfaces owned or operated by you (collectively, “Your Properties”) and actions such users take on Your Properties for Reddit to match with information about users who saw or interacted with your Ads on Reddit. Event Data includes: (i) actions users take on or with respect to Your Properties (e.g., add to cart, purchase, and application downloads); (ii) other conversion events (e.g., offline purchases and conversions occurring through other channels like televisions or gaming devices); and (iii) matching parameters (e.g., email addresses, cookie IDs, and device IDs).
• “Customer List Data” means data provided by you or any third party that enables an individual to be directly identified (e.g., email addresses, device IDs, and phone numbers) for Reddit to match with information about Reddit users to create Custom Audiences (defined below).

2. Reddit’s Use of Business Tool Data

You agree that Reddit may use Event Data, either alone or in combination with other metrics collected by Reddit, to:

• Measure the impact and performance of your Ads (e.g., by allowing you to track actions that visitors to Your Properties take after seeing or clicking an Ad on Reddit);
• Provide and improve the Ads Platform and Ads Services, including by optimizing the Ads Platform, Ads Services, and advertising decisioning; 
• Create targeting audiences of individuals who visit Your Properties (“Retargeting Audiences”); 
• Create lookalike targeting audiences (“Lookalike Audiences”) of Reddit users with similar characteristics to the members of your Retargeting Audiences; and
• Comply with applicable laws or regulations and provide safety, security, and fraud prevention services.

You agree that Reddit may use Customer List Data, either alone or in combination with other metrics collected by Reddit, to:

• Create targeting audiences of Reddit users whose information matches (or does not match) your Customer List Data (“Custom Audiences”); 
• Create Lookalike Audiences of Reddit users with similar characteristics to the members of your Custom Audiences; and
• Comply with applicable laws or regulations.

Retargeting Audiences, Lookalike Audiences, and Custom Audiences are referred to collectively in these Business Tool Terms as “Audience Segments.”

3. Restrictions on the Use of the Business Tools

• Reference in your Ads or Ads Materials any selection criteria or presumed knowledge about any individual based on your use of the Business Tools; or
• Use Audience Segments for any purpose other than to target your Ads to Reddit users and in connection with your use of the Ads Services.

Reddit will not:

• Retain unmatched Customer List Data after the match process to create an Audience Segment is complete;
