We ask before sending any marketing messages because we need your okay first — so the opt-in screen keeps appearing until you choose to opt in. It's completely optional. Opting in just means we can send you the occasional update about new features and what's new at Split Pay. If you skip it, nothing changes — you'll still get all your payment and account messages as usual. And if you ever want to stop marketing messages, just reply STOP; that won't affect your payment or login texts.
