Yes, HAVA funds in general, including CARES Act funds, can be used to develop or improve the technology, privacy, and efficiency of address confidentiality programs. Survivors of domestic and sexual violence, stalking, and trafficking should be able to receive election mail, including absentee ballots, without disclosing their physical address to the public. State-administered address confidentiality programs help victims from being located by their perpetrator through public records by providing substitute addresses and confidential mail forwarding services. However, keep in mind that you need to allocate the funds appropriately based on the benefits of the cost to the various activities of the office. If the system to develop or improve address confidentiality is also used for activities unrelated to improving the administration of federal elections or in response to the pandemic, only the percentage of costs associated with the administration of federal elections can be charged to the CARES Act grants.
