SMS Communications Consent

Who we are

Synalux LLC is a business software company that provides point-of-sale (POS) solutions for restaurants, retail, and hospitality businesses, as well as practice-management tools for independent healthcare providers. Our toll-free messaging number is +1 833 991 5203.

The end recipients of our SMS messages are the customers, merchants, patients, and staff of the businesses that use Synalux. We do not send marketing messages to the public, and we do not sell, rent, or share contact information with third parties.

What messages we send

Point-of-sale & retail:

• Order confirmations — sent when an order is placed or updated.
• Payment receipts — sent after a transaction is processed.
• Pickup & delivery notifications — sent when an order is ready for pickup or out for delivery.
• Reservation confirmations — sent to confirm or remind about upcoming reservations.

Healthcare & practice management:

• Appointment reminders — sent 24 hours and 1 hour before a scheduled visit or telehealth session.
• Telehealth join links — sent at the start of a scheduled video session.
• Billing & invoice notifications — sent when a new invoice is issued or a payment is received.

All products:

• Customer-care responses — replies to inbound questions sent to our service number.
• Account & service updates — sent when account settings, terms, or policies change.

Typical frequency is 5–15 messages per month per end user. Frequency may increase during active business periods (e.g., multiple daily orders or appointment-heavy weeks) and around billing cycles.

How we collect opt-in consent

SMS consent is collected through a standalone, opt-in-only checkbox on the Synalux account-registration page at synalux.ai/patient-portal. A live, no-login preview of the exact opt-in UI is available at synalux.ai/sms-consent/preview.

SMS consent is split into two separate checkboxes by use case. Each checkbox is:

• Separate from the Terms of Service / Privacy Policy checkbox and from each other.
• Unchecked by default. The user must affirmatively check it before any SMS is sent.
• Optional. Declining either or both SMS checkboxes does not prevent the user from creating a Synalux account or receiving any product or service.
• Not bundled with any other consent, authorization, or agreement.

Checkbox 1 — POS & Customer Care (verbatim):

I agree to receive text messages (SMS) from Synalux LLC for order confirmations, payment receipts, pickup & delivery notifications, and customer-care responses. Message frequency typically 5–15/month. Msg & data rates may apply. Reply STOP to cancel, HELP for help. This consent is not required to create an account or receive services.

Checkbox 2 — Healthcare (verbatim):

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. Msg & data rates may apply. Reply STOP to cancel, HELP for help. This consent is not required to create an account or receive services.

When the box is checked, a row is written to sms_consents capturing the user's ID, phone number, exact consent text version, timestamp, and source IP. No SMS may be dispatched to a phone number that does not have a matching granted=true record. The consent record is retained for the lifetime of the account plus the retention period required by applicable state and federal law.
