Localytics collects IDFA when the AdSupport.framework is in your app. This is in compliance with Apple's policies around the use of advertising identifiers.
If you use Localytics Attribution, the IDFA is used to attribute app installs to previously-served advertisements. In Localytics Remarketing, the IDFA is used to identify the people in a Localytics Audience to third-parties like Facebook.
If you include the AdSupport.framework in your app and you are answering Apple's App Store submission form, the appropriate responses may vary depending on which Localytics features you use. In general, we recommend that you check the following use-cases:
- Attribute this app installation to a previously served advertisement
- Attribute an action taken within this app to a previously served advertisement
