How Rostr texting works
Last updated 5 November 2026
Rostr is booking and payments for independent youth-sports coaches. Rostr is a product of High5 Labs LLC, 4030 Wake Forest Road, Ste 349, Raleigh, NC 27609. This page shows who gets our texts, exactly how they agree to them, exactly what the texts say, and how to stop them. Questions: support@rostr.coach. Our Privacy Policy and Terms cover the rest.
Every text comes from one number, (984) 231-2505, and a person opts out or asks for help by replying to it.
Who gets texts
Only adults who gave us their own mobile number and ticked an unchecked box to say yes:
- Parents who book a session or buy a package on a coach's public booking page
(the address looks like
rostr.coach/and the coach's name). - Coaches who tick a matching box in their account Settings after they have created an account.
Nobody is texted unless they ticked the box for that booking or purchase. Leaving it unticked never stops a booking: the booking or receipt is shown on a page instead. Numbers are never bought, rented, imported or shared.
The consent a person sees
The box is unchecked, separate from accepting the Terms, and optional. This is the wording on a coach's booking page, above the button (see it live at rostr.coach/evan):
When a parent buys a package, the first sentence reads "...about your Rostr bookings and packages from Rostr...: requests, confirmations, reminders, receipts, changes and counter-offers, completion, credit and refund notices, package balance and expiry notices, and sign-in links you ask for", and the rest is the same. In a coach's account Settings it reads:
A parent who already ticked a box can later ask for a one-time sign-in link at rostr.coach/parents/link. No new consent is collected there: the link is texted only to a number that already has texts turned on, and to nobody else. The text reads exactly:
Links in the examples carry a private per-booking code; the ones shown here open a sample booking. To see the booking page itself, open rostr.coach/evan, a sample coach.
Each tick is stored with the number, the time and these exact words. The coach signup form on rostr.coach collects no text consent.
What the texts say
Every text begins with "Rostr" and ends with how to stop. These are real messages, sent only about a booking or purchase the person made:
Right after someone ticks the box we send one confirmation before anything else:
Message frequency varies with how often a person books or coaches. Message and data rates may apply. We send nothing promotional, and nothing to children: sessions are booked and paid for by an adult.
Stopping, restarting and help
STOP, STOPALL, UNSUBSCRIBE, CANCEL, END, QUIT, REVOKE or OPTOUT: no more texts, on every coach's page at once. We send one reply: "Rostr (High5 Labs): you're unsubscribed and won't get any more texts from us. Reply START to resubscribe. To cancel a session instead, use your booking link."
START or UNSTOP: texts resume.
HELP or INFO: "Rostr (High5 Labs): for help email support@rostr.coach or see rostr.coach. Msg frequency varies. Msg&data rates may apply. Reply STOP to opt out."
A person can also email support@rostr.coach and a person reads it.
