# Why we ask for each setting

> What each MMP setting is for, and why Link needs it to reward your players.

Every setting in the [MMP guides](https://docs.almedia.dev/publisher/mmp.md) has a reason. This page explains what each
one does, so you can judge the request rather than just follow it — and answer anyone on your
side who asks why.

> [accordion] Why a long in-app event postback window? (Lifetime highly recommended, minimum 180 days)
>
> Your MMP counts the window from install, but players link whenever they see the Link pop-up,
> often months later. With a 90-day window, anyone who installed more than 3 months ago sends
> nothing after linking, so we can't reward them. **180 days is the minimum. We highly
> recommend Lifetime**, which most partners use.

> [accordion] Why player-level ad revenue?
>
> In AppsFlyer this is the **Access ad revenue raw data** permission.
>
> It's how we see the ad revenue each linked player generates. We use it to reward ad-based
> tasks, such as the default "keep playing" task. Aggregated revenue can't be tied to a player,
> so it can't be rewarded.

> [accordion] Why data for all users, not only users Almedia brought you?
>
> The setting is worded differently per MMP — "all media sources, including organic",
> "Send All", "all users".
>
> The install is how we match a linked Freecash account to the player's device, so their events
> reach the right person. Most players who link came to your game organically or through other
> networks, not through us. Without data for all users, those players get no rewards and Link
> doesn't work.

> [accordion] Why sessions / app opens?
>
> They power the daily login reward, which brings linked players back to your game every day.

> [accordion] Why in-app purchases?
>
> We use purchase data to fund rewards on in-app purchases: linked players get cashback when
> they buy something in your game. Please share it even if your game has few purchases.

> [accordion] Why turn off Advanced Privacy for iOS? (AppsFlyer)
>
> With Advanced Privacy on, AppsFlyer withholds player-level iOS data from partners. We then
> can't match or reward your iOS players.

> [accordion] Why probabilistic modeling? (Adjust)
>
> It lets Adjust match iOS players who don't share their IDFA, so those players' events reach us
> and they can be rewarded too.

> [accordion] Can we share data only for players who linked?
>
> No. MMPs share data per app, not per player. We match linked players on our side.

> [accordion] Does sharing this data change our attribution or give Almedia credit for installs?
>
> No. Sharing data doesn't change who gets credit for an install.

## Still unsure?

Setting names and event names in the guides are reproduced exactly. If something in your
dashboard is worded differently, ask your account manager rather than guessing the nearest
match.
