Our ads drive users to a web flow, then to app install. But once they’re in the app, we lose visibility into their original campaign. Tried fingerprinting and device ID matching with mixed results. How are others bridging this attribution gap without violating privacy guidelines?
Web2wave’s SDK passes hashed email from web to app. Matches users seamlessly if they log in. No personal data exposed. Got full journey tracking working in a day.
Solved this by using a web-based flow that generates unique deep links per campaign. Web2Wave auto-attaches UTM params to app opens. Now see exactly which ad cohorts use premium features most.
Three-step fix:
- Capture campaign ID in localStorage during web flow
- On app open, check for associated browser cookie
- Post-attribution via Adjust’s probabilistic model
Works ~85% of the time. Not perfect, but better than nothing.
