# Cross Device Attribution

## Cross-Device Attribution

Freshpaint's cross-device attribution tracks conversions that span multiple devices, giving ad platforms proper credit even when a click and its resulting conversion happen on separate devices.

### How It Works

When a visitor clicks an ad on mobile and later completes a conversion on desktop, Freshpaint's identity resolution recognizes them as the same person. Freshpaint then hydrates the conversion event with the original click ID from the ad platform, ensuring the conversion is attributed to the correct source.

Identity matching uses deterministic signals: email, phone, or a customer-provided ID.

### Enable Cross-Device Attribution

Cross-device attribution is available on request. To activate it, contact Freshpaint Support or the account management team. Once enabled, the feature works automatically — no additional code changes are required.
