Cookie Policy & First-Party Attribution Ledger.

Vanguard Signal LLC enforces strict first-party attribution hygiene—isolating session UTM parameters and server-side CRM signals while prohibiting third-party data broker pixels across our entire web architecture.

FIG 01 // FIRST-PARTY COOKIE & ZERO-BROKER TELEMETRY PIPELINE

COOKIE 01 // STRICTLY NECESSARY STORAGE

Essential Routing, CSRF & Session Integrity

Required cookies preserve form security tokens, breakpoint preferences, and load-balanced edge routing on vanguardsignal.io. These strictly necessary identifiers store zero personal identity fields and expire automatically upon session close.

COOKIE 02 // FIRST-PARTY UTM PERSISTENCE

180-Day Campaign Parameter Attribution

To verify paid search and LinkedIn ABM pipeline contribution, we store a first-party cookie (__vs_utm) recording initial utm_source, utm_medium, utm_campaign, gclid, and li_fat_id values for 180 days under SameSite=Lax protection.

COOKIE 03 // SIMULATOR STATE ISOLATION

Zero-Cookie ROAS Calculator Execution

All budget sliders, ACV inputs, and CAC payback curves inside the VanguardROASSimulator execute 100% in ephemeral browser memory. No cookies or external analytics events capture your financial model inputs unless you submit an audit brief.

COOKIE 04 // ZERO BROKER SYNDICATION

Prohibition of Third-Party Retargeting Pixels

Vanguard Signal deploys zero cross-context behavioral ad brokers, shadowy B2B IP deanonymization scripts, or third-party cookie-syncing pixels. Your executive team can inspect our case studies without triggering external ad-network stalking.

COOKIE 05 // GLOBAL PRIVACY CONTROL (GPC)

Automated GDPR, UK-GDPR & CCPA Honoring

Our telemetry layer automatically detects browser-level Global Privacy Control (Sec-GPC: 1) and Do Not Track headers, immediately suppressing non-essential attribution cookies for visitors in the EEA, UK, Switzerland, and California.

COOKIE 06 // EXPIRATION & PURGE CONTROLS

One-Click Browser Clearing & DPO Contact
