This page shows the exact standalone SMS-consent checkbox a Synalux LLC user sees on the registration page. No login required.

1. Three separate, unbundled checkboxes

Below is the live UI (rendered as static HTML on this preview page). The Terms-of-Service / Privacy-Policy checkbox and the two SMS-opt-in checkboxes (POS and Healthcare) are three distinct controls. None is checked by default. The SMS checkboxes are optional and never gate account creation.

(Optional) I agree to receive text messages (SMS) from Synalux LLC for appointment reminders, telehealth session links, and billing notifications. Message frequency typically 2–8/month.

2. What Synalux records on opt-in

When the SMS checkbox is checked and the user submits the form, the server writes a row to sms_consents capturing:

User ID (the account being created)
Phone number (E.164, validated)
Exact consent-text version that was displayed
Timestamp (UTC)
Source IP + user-agent (for audit)
granted = true

Outbound SMS is blocked at the API layer for any phone number that does not have a matching granted = true record.

3. Sample messages

The full set of sample messages, per category, is on the main consent page: synalux.ai/sms-consent. One example:

“Synalux: Order #1087 confirmed — 2 items, total $34.50. Estimated pickup: 20 min. Reply HELP for help, STOP to opt out.”

4. Opt-out

Reply STOP (also END, QUIT, CANCEL, UNSUBSCRIBE) to any Synalux SMS. Further messages stop within 24 hours; one confirmation reply is sent. Opt-out is also available by toggling SMS off in your account settings, or by emailing support@synalux.ai.
