<b>FAQ: Can I still use device fingerprinting for in-app attribution?</b>

Many guides still mention it; on iOS it's effectively dead and on Android it's shrinking. Apple bans probabilistic fingerprinting for ATT-restricted attribution, and MMPs only allow it in narrow re-engagement cases.

— ✓ Still legal as a last-resort fallback on Android with GAID present
— ✓ Useful for deferred deep-link matching within seconds of a click
— ✗ Apple prohibits it as the attribution method under ATT — accuracy aside, it's a policy risk
— ✗ Match windows are tiny; accuracy degrades fast past a few seconds

Fingerprinting is a fragile bridge, not a foundation. Build on SKAN aggregation and consented deterministic IDs instead.

Verdict: rely on it nowhere you'd be embarrassed to explain to Apple; treat as emergency fallback only.
Best for: beginners reading outdated attribution tutorials.
