California’s AB 1043—often called the Digital Age Assurance Act—marks a simple but significant shift: instead of every app guessing a user’s age, operating systems and app stores will send an age-bracket signal to apps. That shifts age assurance from a scattered, app-by-app problem to a shared layer of infrastructure. It’s privacy-preserving (no default ID uploads), it gives developers actual knowledge of a user’s age range, and it creates a clearer path to age-appropriate defaults.
What it doesn’t do is finish the job for you.
To comply and still grow, product and trust teams need a progressive age-assurance ladder: rely on the OS signal when it’s available, and step up seamlessly to low-friction checks—or hard verification—only when risk or regulation demands it. That’s where Kairos fits cleanly.
What AB 1043 actually changes (in plain English)
- OS/App-store age signal. During device or account setup, a parent or guardian selects a child’s age/birthdate. The operating system and app store then expose a non-personal age bracket to apps (e.g., under 5; 5–9; 10–12; 13–15; 16–17; 18+).
- “Actual knowledge” for developers. When your app requests and receives that signal, you’re expected to treat it as the primary indicator of age. In other words, you can act on it—and you’re presumed compliant when you do so in good faith.
- Parental consent signaling (store context). If the user is under 16, the app store may have to capture and send parental consent status to developers as part of the signal.
- Enforcement & scope. Civil penalties are enforceable by the California Attorney General; the bill is framed to minimize data sharing and reduce constitutional risk by avoiding blanket content mandates.
- Timing. The law’s requirements kick in beginning January 1, 2027.
For product leaders, this means you’ll have a reliable, privacy-first way to know a user’s age range without forcing IDs at signup. For compliance leaders, it’s a clearer, auditable standard that reduces ambiguity around “actual knowledge.”
A practical playbook: the progressive age-assurance ladder
- Accept the OS age signal (default).
Treat it as authoritative. Build your permissions, defaults, and safety rails around brackets (e.g., messaging, discovery, recommendations, in-app spending, and data sharing settings). Log receipt of the signal and key decisions for audits. - Escalate to selfie-based age estimation (when needed).
If the signal is missing (web contexts, legacy devices), inconsistent with observed risk, or the user is accessing higher-risk features (live chat, UGC creation, payments), use a one-selfie age estimate to keep friction low while preventing underage access to restricted features. - Escalate to ID + liveness (for regulated or high-risk cases).
Where law or policy requires strict proof (alcohol, adult, gambling, high-value transactions, appeals/overrides), move to document verification with liveness and optional biometric match. Keep this narrow and event-driven to protect conversion.
This ladder respects AB 1043’s privacy intent while giving you consistent guardrails, clear escalation points, and a strong audit trail.
Where Kairos fits (and why it complements AB 1043)
Kairos is API-first, with optional on-prem deployment. That means you can keep your existing identity stack and call only what you need, when you need it—no monolithic SDKs or heavy migrations.
- Age Estimation via selfie (low friction): Gate mature features quickly when the OS signal isn’t available or is contradicted by risk signals.
- ID Document Verification + Liveness (hard proof): Capture compliant proof of age when regulation or policy requires it, and use liveness to prevent spoofing.
- Biometric Match (optional): Compare selfie to ID headshot to reduce impersonation in appeals or repeated failure scenarios.
- API + On-Prem: Integrate over a clean API, and, if you have strict data residency or privacy requirements, deploy on-prem to keep sensitive media in your environment.
Implementation checklist
- Signal intake & storage
- Request OS/app-store age signal at download/launch and on account link.
- Cache the bracket and consent status in your user record; store minimal metadata (timestamp, source, version).
- Make the signal available to downstream risk and policy engines; never share it externally.
- Age-bracket policies
- Define defaults per bracket (DMs, social graph expansion, public discovery, recommendations, notifications, spending, personalization, ads).
- Wire parental tools where relevant; reflect consent state from the store context.
- Escalations
- No signal → call Kairos Age Estimation (no document required).
- Conflict or high-risk → Kairos ID + Liveness; optionally add biometric match to resolve appeals.
- Log all escalations and outcomes with reason codes.
- Auditing & appeals
- Maintain an internal ledger: signal receipt, policy applied, escalations, and final decisions.
- Provide an appeal path that upgrades assurance (e.g., from age estimate → ID + liveness).
- Privacy by design
- Minimize data (store age bracket, not full DOB, unless strictly needed).
- Set retention aligned to legal needs and your threat model.
- Segment storage for media (selfies/IDs) and restrict access.
- Roadmap & readiness
- Pilot on web and legacy surfaces where the signal won’t arrive.
- Validate your January 2027 readiness with partners (payment, fraud, analytics).
- Run an A/B: signal-only vs. signal+ladder to quantify conversion and safety deltas.
Why act now
Even before the effective date, aligning to AB 1043’s model pays off: your UX gets simpler (one source of age truth), compliance risk goes down (presumption of good-faith reliance on the signal), and your team can reserve heavier checks for the minority of cases that truly need them. That’s a win for families, regulators, and your funnel.
