Sandlot SMS Opt-In Flow

Overview

Sandlot collects SMS consent during the app onboarding process. SMS notifications are optional and not required to use the app.

Opt-In Process

Step 1: Phone Authentication

Users enter their phone number to sign in via SMS verification code.

Step 2: Profile Setup

After authentication, users complete their profile (name).

Step 3: SMS Notifications (Opt-In)

Users are presented with a dedicated screen that explains SMS notifications:

Screen Title: "Stay Updated"

Description shown to user: "Get notified when someone joins your game or starts a new sandlot at fields you follow."

Two clear options:

1. "Enable Notifications" - User opts in to receive SMS
2. "Skip" - User can skip and still use the full app

What Users Receive

When users opt in, they receive SMS notifications for:

• New games started at fields they follow
• Players joining games they created
• Players joining games they're attending

Opt-Out

Users can opt out at any time by:

• Unfollowing fields (stops notifications for that field)
• Leaving games (stops notifications for that game)
• Replying STOP to any message
