What is First-Party Data?
Behavioral and account data collected directly from your own product and site with user consent. It survives cookie deprecation and platform shifts, which is why owned telemetry beats rented audience segments.

Cookieless Tracking
Measurement without third-party cookies: first-party identifiers, aggregated reporting, and modeled conversions. Built for browsers and regulations that block cross-site tracking, at the cost of individual-level precision.
Consent Mode
A tracking setup that adjusts data collection to each visitor consent choice: full measurement when granted, modeled or aggregate-only when declined. Preserves partial signal legally instead of choosing all-or-nothing tracking.
PII Redaction
Stripping emails, tokens, keys, and secrets from logged payloads before storage or display. Redaction belongs in the pipeline itself, since downstream dashboards and exports inherit whatever the collector kept.
Autocapture
Automatic collection of clicks, pageviews, and form interactions without per-element instrumentation. Fast to start but noisy: retroactive data comes with vague names and mystery events that explicit tracking would have labeled.
Explicit Events
Hand-defined tracking calls placed at meaningful product moments: signup completed, checkout started, invite sent. Explicit events cost engineering time upfront and pay back in clean names and trustworthy funnels.
Event Taxonomy
The naming contract for analytics: object-action conventions, required properties, and ownership per event. Taxonomies prevent the analytics swamp where three teams log the same signup three different ways.
