SMS messaging consent

DojoStack Labs LLC ("DojoStack," "we," "us," or "our") provides SMS messaging services to martial arts schools and their students for important communications including class reminders, promotional offers, billing notifications, and other school-related updates.

How opt-in works

Initial consent collection

Consent is collected when you:

• Sign up for membership at a DojoStack-powered martial arts school
• Complete an online form and check the SMS opt-in box
• Send a keyword such as START or JOIN to your school’s designated phone number
• Provide your phone number and explicitly agree to receive text messages

Types of messages you may receive

• Transactional: Class reminders, schedule changes, and membership confirmations
• Billing: Payment reminders, receipt confirmations, and failed payment notifications
• Promotional: Special offers, trial class invitations, and event announcements
• Operational: School closures, emergency alerts, and important updates

Message frequency

Message frequency varies based on your school’s communication needs and your membership status. You may receive anywhere from 2–10 messages per month. Promotional messages will be sent no more than four times per month unless you’ve opted into specific campaigns.

Message and data rates

Standard message and data rates may apply based on your mobile carrier plan. DojoStack does not charge for SMS messages, but your carrier may charge for incoming text messages.

Your rights and opt-out options

Opt back in

If you previously opted out and wish to receive messages again, reply START or UNSTOP to your school’s phone number, or contact your school to re-enable SMS.
