Why the question comes up
There are several reasons clients care where their information is held, and they are not all legal:
- Contracts. Larger clients sometimes include terms in their agreements about where their data may be kept or processed.
- Sector rules. Some industries and some government work carry their own expectations about data location. Your attorney can tell you whether any apply to a given client.
- State privacy laws. Laws such as the California Consumer Privacy Act and similar laws in other states focus on how personal information is collected, used and shared, and often on which service providers handle it.
- Insurance. Cyber insurers may ask which outside services hold sensitive data, as part of judging risk.
- Plain trust. Many clients simply want to know, and an evasive answer worries them more than any particular location would.
Whatever the reason, the person asking usually wants a straight answer rather than a reassurance.
