GoStork collects SMS consent in two separate steps on the phone number step of account signup at https://app.gostork.com. Consent to receive text messages is never a condition of using GoStork or of any purchase.
The user enters their mobile number and taps “Verify phone number”. This sends a single one-time verification code that the user has explicitly requested. Immediately above the button, every user sees this notice:
GoStork will text you a one-time code to verify this number. Msg & data rates may apply.
On the same screen, a separate checkbox offers ongoing notification texts. The box starts unticked, and signup completes whether or not it is ticked. The checkbox label reads:
Yes, text me updates about my journey
Match updates, appointment reminders, and messages from providers you connect with, by text from GoStork. Optional. Frequency varies, msg & data rates may apply. Reply STOP to cancel, HELP for help. Terms ยท Privacy
This is the screen every user sees:

What we send: one-time account verification codes, and – only for users who ticked the opt-in box – match updates, appointment confirmations and reminders, and messages from providers you connect with.
Message frequency varies. Msg & data rates may apply.
Reply STOP to unsubscribe, or HELP for assistance. You can also turn notification texts on or off at any time from your account settings.
Consent to receive text messages is not a condition of using GoStork or of any purchase. We never sell or share your number.
