Data Processing Options for US Users

To utilize this feature, you must proactively enable Limited Data Use. Visit Meta’s developer documentation for details.

If you do not want to enable Limited Data Use (LDU) mode, pass an empty string as a value of mediation extras with key FB_dp in initialize method:

CASMobileAds.initialize(
    casId: casId,
    mediationExtras: {'FB_dp': ''},
    ...
);

To enable LDU for users and specify user geography, set 'LDU' to mediationExtras:

CASMobileAds.initialize(
    casId: casId,
    mediationExtras: {'FB_dp': 'LDU'},
    ...
);
