What are our policies for retaining customer data used for ad targeting on Facebook Ads?

Facebook's policies for retaining customer data used for ad targeting are determined by Facebook, and I am not privy to their most current internal policies. However, I can provide some general information about how Facebook handles customer data in the context of ad targeting.

Facebook retains user data as long as it's necessary to provide services, maintain the security of its platform, and comply with legal obligations. For ad targeting, they may use data for specific periods, such as the duration of a campaign, after which they may delete or anonymize the data.

When it comes to customer data provided for ad targeting, Facebook typically uses it to match with their user base, create custom audiences, and deliver relevant ads. Once the purpose is fulfilled or the data is no longer needed, Facebook may delete or anonymize the data. However, I strongly recommend checking Facebook's official resources and policies for the most accurate and up-to-date information.
