k ≥ 8 (k-anonymity)

BudAlly's rule that no segment, cohort, benchmark or median is shown unless at least 8 contributors (customers, stores or tenants) are in it. Cells below the threshold display '—, k < 8'.

The threshold protects both customers and other stores. Put simply: a six-person lapsed-customer segment identifies six people; a median of three stores is one store's price. Privacy and statistics agree here.

BudAlly applies the rule as RI-ALL-10 and enforces it at the API, not in the prompt, so an agent or connected tool gets the same "—, k < 8" a person sees, and a client can't opt out. Pooling across operators also needs explicit opt-in: a store's rows join a network median only if it opts in, and only with 8 or more contributors.

The same rule governs what BudAlly publishes. Figures on the stats page that come from BudAlly customers are marked 'BudAlly ledger' and carry their contributor count, never fewer than 8, and their window. Brands see sell-through only from stores that opt in, aggregated at k ≥ 8.
