Deferred Deep Linking
Implement deterministic deferred deep linking on Android and iOS without fingerprinting or a proprietary SDK.
Current support
ZipQuantum supports deterministic deferred recovery on both mobile platforms. Android uses a Play Install Referrer token. iOS uses a short-lived, signed, user-initiated handoff bound to the link host and app bundle. Neither flow uses fingerprinting, probabilistic matching, or a user API key inside the app.
Installed flow
Universal Links and App Links open the installed app directly. The app validates the incoming URL and routes to the intended content.
Post-install flow
- A Smart Link resolves the link and presents the appropriate store-safe handoff when the app is absent.
- Android carries an opaque token through Play Install Referrer. iOS lets the user explicitly copy the signed handoff before opening the App Store.
- On first open, the app reads the platform handoff and sends the opaque token to the public recovery endpoint.
- ZipQuantum validates expiry, signature, host, app identity, and one-time use before returning the link context.
- The app opens the intended route.
Privacy and security
Recovery tokens are opaque, short-lived, scoped, and replay-resistant. They do not contain a user API key or require device fingerprinting. Optional device context and user-level measurement remain separate and consent-controlled.
