How long should we retain customer data after it's been uploaded to Facebook Ads?

Facebook's policies and best practices generally recommend that you should not retain customer data any longer than necessary for ad targeting purposes. Once you have achieved your advertising objectives or the data is no longer needed, you should remove it from Facebook Ads.

However, the specific retention period may depend on various factors, such as the nature of your campaign, your company's data retention policies, and any legal or regulatory requirements. It is essential to consider these factors when determining the appropriate retention period for your customer data.

In general, you should aim to minimize the amount of time you store customer data and delete or anonymize it as soon as possible after the ad campaign has ended or the data is no longer required. This approach helps maintain user privacy and ensures compliance with data protection regulations.

For the most accurate guidance, consult Facebook's official resources and consider seeking legal advice if necessary to ensure that your data retention practices comply with all applicable laws and regulations.
