SMS is disabled by default. Only the user receiving the SMS can opt their own number in — administrators cannot enable SMS on behalf of another user.
The Notifications screen lists all subscribers per notification type. Each row shows an email address and an SMS Opt-in checkbox. An admin sees the checkbox enabled only for their own row; other users' checkboxes are greyed out and non-interactive.
Clicking the checkbox opens a modal confirming the mobile number registered to their profile and prompting them to choose a delivery schedule. Options are Off (opt out), Always, or Mon–Thu. When the user selects Always or Mon–Thu, the modal displays the following consent disclosure:
The user must check "I agree to the Privacy Policy and Terms of Use" (linked to onesitekit.com/privacy.html and onesitekit.com/terms.html) before the Save button becomes active.
After saving, the row updates to show a filled blue checkbox labelled SMS Opt-in · Always (or the selected schedule) and a Send Test button. The other admins' rows remain greyed out — each user must opt themselves in from their own account.
Users can opt out at any time in two ways: (1) reply STOP to any SMS message, or (2) uncheck their SMS Opt-in checkbox in Admin → Notifications. Either method immediately stops further messages.
Unchecking the active checkbox shows a confirmation modal identifying the phone number being unsubscribed and the notification list it applies to. The user confirms by pressing OK.
