Overview
Browser privacy signals become legally actionable only when a governing rule connects a clear consumer choice to a defined opt-out purpose and a recipient's duty. The series moves from California and Colorado scope, provenance, persistence, and downstream processing to DROP, showing why broad reach does not mean every privacy right or automatic deletion.
Learning outcomes
- A machine-readable signal is legally actionable only when the applicable rule recognizes its purpose, the consumer's choice meets its conditions, and the recipient is bound to act.
- California and Colorado attach different purposes and choice-provenance requirements, so similar wire formats do not guarantee identical legal effect.
- A recognized opt-out must be applied, propagated, and maintained within its supported scope until compliant consent changes it; silence is not opt-in.
- DROP is a separate verified data-broker deletion workflow with hashed matching, recurring reconciliation, future-record suppression, downstream duties, and differentiated status reporting.

PlansFAQ
When does a browser privacy signal become a legal request?
It becomes a legal request when the governing rule gives its communicated purpose legal meaning, the consumer's choice satisfies required conditions, and an in-scope business or controller must process it.
How far can a browser privacy signal reach without a name?
It can cover the sending browser or device and an associated pseudonymous profile without a name; it can extend to a known consumer or offline activity only when the recipient can make the required connection.
Does a browser opt-out cover deletion or every privacy right?
No. California and Colorado attach the signal to defined opt-out purposes, such as sale, sharing, or targeted advertising; deletion and other rights require their own applicable request path.
Is California DROP the same as a browser privacy signal?
No. DROP is a separate California workflow in which verified consumers send deletion requests to data brokers through hashed lists, recurring matching, downstream instructions, and status reporting.
