SMS & Messaging Policy
Last updated: July 2, 2026
What messages we send
Synalux POS sends transactional SMS and WhatsApp messages to restaurant customers in the following scenarios:
- Order confirmations — order number, total, and estimated pickup time after an order is placed via phone, WhatsApp, or web.
- Payment links — secure Stripe Checkout links so customers can pay for their order by card.
- Pickup notifications — a message when the order is ready for pickup.
How customers opt in
Customers explicitly opt in to receive transactional SMS by initiating an order through one of these channels:
- Phone call — the customer calls the restaurant’s ordering number and places an order via an automated voice system. Before the order is confirmed, the system reads: “By confirming this order, you agree to receive order updates via text message. Reply STOP to opt out.” The customer’s caller ID phone number is used for SMS delivery.
- WhatsApp — the customer initiates a conversation by sending a message to the restaurant’s WhatsApp number. By sending the first message, the customer opts in per WhatsApp’s user-initiated conversation policy.
- Online ordering — during web checkout, the customer enters their phone number in a clearly labeled field: “Phone number (for order updates via SMS).” A checkbox labeled “I agree to receive order updates via SMS. Msg & data rates may apply. Reply STOP to opt out.” must be checked before the order can be placed.
Messages are only sent after the customer actively places an order and consents to messaging. We do not send marketing, promotional, or recurring campaign messages. Each order generates 1–3 transactional messages only.
Call to action examples
Below are the specific points where customer consent is collected:
1. Voice ordering (phone call)
“Your order total is $24.50. By confirming, you agree to receive order updates via text message at this phone number. Say ‘confirm’ to place your order, or ‘cancel’ to cancel.”
Consent is verbal, recorded in the call log. Customer must say “confirm” to proceed.
2. Online checkout
Phone number field: “Phone number (for order updates via SMS)”
Consent checkbox: “☐ I agree to receive order updates via SMS. Msg & data rates may apply. Reply STOP to opt out.”
Checkbox is unchecked by default. Order cannot be submitted without checking it when a phone number is provided.
3. WhatsApp
Customer initiates the conversation by messaging the restaurant’s WhatsApp number first. Per WhatsApp Business API policy, the customer’s first message constitutes opt-in for that conversation.
How to opt out
Reply STOP to any message to stop receiving SMS from Synalux POS. You can also contact the restaurant directly to be removed from messaging.
Message frequency
Typically 1–3 messages per order (confirmation, payment link, pickup ready). No recurring messages beyond the scope of a single order.
Message & data rates
Standard message and data rates may apply depending on your carrier plan.
Third-party sharing
We do not share, sell, or transfer your mobile phone number, messaging consent, or opt-in data to any third parties or affiliates for marketing or promotional purposes.
Your phone number is used solely by Synalux POS to send transactional messages related to your restaurant order.
