The Brain shares wisdom across brands. It does **not** share data across brands. This page explains how that line is enforced. ## The anonymisation invariant Nothing in the cross-brand pattern library is brand-attributable. That's the load-bearing invariant. It's enforced in two layers before any observation can be promoted into a pattern: 1. **A deterministic scrubber** strips brand IDs, currency amounts, account identifiers, domain names, and other domain-specific tokens. 2. **An LLM scrubber** reads the already-scrubbed observation and rewrites it into a generalised, neutral form — bands ("low / medium / high") instead of exact numbers, "the brand" instead of a brand name. Only after both layers run does an observation become eligible for promotion into a pattern. ## What other brands see When another brand's agent recalls a pattern, they see: * The plain-English summary (e.g. *"calls placed before 10am IST tend to have \~2× higher pickup rate"*). * The confidence tier (strong / moderate / weak). * The anonymised evidence count (e.g. *"corroborated across 7 brands"*). ## What other brands never see * Your brand name, your store URL, or any handle that identifies you. * Your specific ROAS, your specific spend numbers, your specific revenue. * The contents of any memory you saved (target ROAS, do-not-ship-to lists, brand voice notes) — memory is brand-scoped and never leaves your workspace. * Your customer data — ever. * Your campaign IDs, your ad account IDs, your platform handles. ## Where the customer Brain ends and the admin Brain begins The Brain in your cockpit is scoped to your **workspace's brands**. It's the operator's surface. There's a separate internal brain — the platform-wide reflector and the admin-level pattern review surface — that lives elsewhere. Paying customers never see the admin brain. The two are physically separated; the customer Brain in your cockpit does not have a path into the admin layer. ## Opting out The Brain's cross-brand learning is on by default for pilot customers. If you'd prefer to operate in a brand-only mode (memory works, but no patterns get promoted out of your brand and you don't see cross-brand patterns), reach out — this is a per-workspace toggle on our side today and will become a Settings option.
