# Attribution policies

When one install finds several visits, the policy decides which one gets the credit. A single visit is always credited.

| Policy | Setting | With several visits |
| --- | --- | --- |
| Latest visit | `latest_visit` | Credits the most recent visit, and each platform receives its most recent click. The default for new websites. |
| First visit | `first_visit` | Credits the oldest visit in the journey, and each platform receives its earliest click. |
| Single visit only | `unique` | Credits nothing: the install is recorded as `ambiguous`, and only webhooks receive it. |

Change the policy in **Settings**. It applies to installs reported after the change; recorded installs keep their result. Installs reported with a handoff token always credit the token's visit and are recorded with the policy `explicit_handoff`.

Several visits usually mean one person came back, but they can also come from different people sharing an OS account, or from different browser profiles. `unique` refuses to guess in those cases, at the cost of crediting fewer installs.
