What user data does Tailor collect?

Tailor is designed to minimize collection of directly identifiable user data.

At a high level, Tailor collects pseudonymous behavioral event data needed to run and analyze experiments, including impressions, clicks, scroll behavior, page interactions, and event timestamps. By default, Tailor generates a random user ID for each visitor. If you choose to pass us your own user ID, it is one-way hashed on the client side before transmission, so we do not store the raw identifier. For authenticated Tailor users on your team, we would also process standard account and authentication data such as name, email, and authentication or account metadata.

If enrichment is enabled (this is optional and only activated on your instruction), Tailor may process IP addresses transiently in order to derive probabilistic company-level and role-level business attributes, for example industry, company size, department, or seniority. Those enrichment attributes are used for personalization, analytics, anomaly detection, and experiment auditing. The IP address itself is processed transiently for enrichment and is not stored in Tailor's personalization or analytics data stores. It may be temporarily retained only in security and operational access logs, which are retained for 60 days and then automatically deleted. We do not attempt to identify named individuals from enrichment data.
