Privacy-stack cases: staying compliant without going dark on data

Privacy-stack cases: staying compliant without going dark on data

Five teams that handled consent and kept their measurement alive. Forward to whoever fears the regulator.

— 1. A retailer's consent-mode v2 rollout — modeled conversions for users who declined; recovered 18% of lost conversion signal legally. Read if consent banners gutted your data.
— 2. A SaaS's data-retention purge — auto-deleted PII past 24 months, cut storage and breach surface; passed a SOC 2 audit clean. The retention-policy template is the gift.
— 3. A media co's first-party data play — traded gated content for consented emails; built a 200K opted-in list that outperformed third-party audiences 2x. Essential post-cookie.
— 4. A fintech's consent-state propagation — wired one consent decision across 9 tools via the CDP; stopped a tool from firing on opted-out users. The propagation map is the lesson.
— 5. A DTC's DSAR automation — automated data-subject requests from 5 days manual to under 1 hour; killed a compliance backlog. Skip if you're tiny; essential at scale.

That's the stack for this week. Forward to a teammate.
