Cross-Device & Multi-Domain
Consent Identity Synchronization

Q: How does cross-domain consent sync work without third-party cookies?

Consent Shield utilizes zero-knowledge encrypted JWT edge tokens, first-party CNAME subdomains, and authenticated user ID hashing (SHA-256) to instantly replicate consent states across domain boundaries without relying on deprecated third-party cookies.

Q: Can consent synchronize between native iOS/Android apps and mobile web?

Yes. Our native mobile SDKs (iOS Swift, Android Kotlin, React Native, Flutter) bind with our serverless consent edge API. When a logged-in or tokenized user grants or revokes consent in-app, the state updates across all web sessions within 15 milliseconds.

Q: Is cross-device identity synchronization GDPR and CCPA compliant?

Fully compliant. Consent Shield never syncs raw PII. All identity mappings use one-way salt hashes and immutable proof logs stored in our Proof Vault.

Propagate user consent choices across your entire domain fleet, mobile apps, and micro-frontends in under 15ms. Eliminate repetitive banner fatigue while remaining 100% compliant with GDPR and CCPA cross-context requirements.
