Consent and Privacy
K-Anonymity Floor
The minimum cohort size, set at fifty couples, below which Love Pulse Labs does not publish any aggregate finding.
Definition
K-anonymity is a privacy property. A dataset has K-anonymity of K if, for every record, at least K-1 other records share the same identifying attributes. Love Pulse Labs sets its publication floor at K = 50 couples. If the consented cohort for any reporting period is below this floor, the report is held until the floor is met.
How it is measured
Before any aggregate query leaves the product boundary, the cohort size is checked against the K-anonymity floor. The check is encoded in code, not policy, and runs in every publication path. A failed check returns no data.
Why it matters
Small datasets can re-identify a single couple even when no name is attached. The K-anonymity floor is the last line between aggregate research and individual exposure. Holding a report is the right answer when the floor is not met. Trust is the product.
