To get actual answers (at least during sane political administrations), the System of Records Notice (“SORN”) is what you want. Whereas the info sites for these programs are typically useless, SORNs are the authoritative document that the federal government issues to identify and characterize systems that store records about data subjects, and include information about retention polices, exceptions, etc.

The last I read the SORN for TSA’s facial recognition, they did commit to deleting identifiable data within 24 hours.

CBP operates their facial recognition under a different SORN, and there are many more caveats, although they also commit to deleting identifiable data within 24 hours for US citizens (only).

That was in late 2024 anyway.
