SMS Program Terms

Effective date: November 10, 2026 · Last updated: November 10, 2026

These terms apply to the text-message program operated by Gogo Sys Inc. (“4ubook”) for merchants and their customers. By opting in, you agree to receive recurring SMS messages as described below. Consent is not a condition of purchase.

1. Program description

4ubook sends appointment confirmations, reminders, cancellation and reschedule notices, waitlist and check-in updates, receipt and account notifications, and customer-care messages. Merchants may also send promotional offers, discounts, and loyalty updates to customers who have separately opted in to marketing messages.

2. How to opt in

• Web opt-in: submit your mobile number and check the consent boxes on a booking page, the Appointment & SMS Notifications page, or a merchant’s signup form.
• In-store or paper opt-in: complete a consent form at a participating merchant and confirm your number with staff.
• Keyword opt-in: text a supported opt-in keyword provided by the merchant to the program number.
• Booking opt-in: provide your mobile number during checkout and keep the notification consent box selected.

3. Message frequency and rates

Message frequency varies based on your appointments and preferences — typically one message per booking, plus one reminder shortly before your appointment. You may receive up to five messages per day during busy periods. Message and data rates may apply. If you have questions about your text or data plan, contact your wireless provider.

4. How to opt out

You can cancel SMS messages at any time by replying STOP to any message. After we receive your request, we send one final confirmation message confirming that you have been unsubscribed, and no further messages are sent unless you opt in again. You can also update your notification preferences by contacting the merchant or emailing 4upos.com@gmail.com.

5. Help

Reply HELP to any message for assistance, email 4upos.com@gmail.com, or call +1 (917) 226-6084. Support hours are Monday to Friday, 9:00 a.m. to 6:00 p.m. Eastern Time.

6. Participating carriers

Participating carriers include AT&T, Boost Mobile, T-Mobile, Metro by T-Mobile, Verizon Wireless, UScellular, and Virgin Mobile. Carriers, including T-Mobile, are not liable for delayed or undelivered messages. Carriers may change or discontinue participation at any time.

7. Your responsibilities

• You confirm that you are the owner or authorized user of the mobile number you provide and that you are authorized to consent to messages at that number.
• You agree to notify us promptly if your number changes or is reassigned.
• You must be at least 18 years old, or have a parent or guardian’s permission, to opt in.

8. Privacy

Mobile information and messaging opt-in data will not be shared with third parties or affiliates for marketing or promotional purposes, and text-messaging originator opt-in data and consent are never sold or rented. See our Privacy Policy for how we collect, use, and protect personal information.
