Privacy Policy
Last updated: September 29, 2026
This policy explains what MyBack9 ("we," "us") collects, why, and the choices you have. Questions? Email hello@myback9.com.
What we collect
Your consultation answers: first name, age range, how often you play, where you feel tight, what your body does to your swing, your flexibility, your nightly time, and your goal. Contact details: your email address. Your progress: nightly tracker entries such as completed stretches and stiffness and sleep ratings. Reminders: if you turn on nightly texts, your mobile number, reminder time, and time zone. Payments: handled by Stripe. We never see or store your full card number.
Usage data and cookies
We record basic events, such as which step of the consultation you reached, using a random ID stored in your browser, so we can improve the product. Your browser also stores your progress and access link locally so you don't have to log in on the same device. If we use advertising or analytics tools such as Google Analytics or the Meta Pixel, they may set cookies to measure visits and ad performance. You can block or clear cookies in your browser settings.
How we use your information
To build and deliver your personalized workbook, save your progress, send your workbook link and receipts, send the nightly reminders you asked for, run a membership you signed up for, answer support requests, and improve MyBack9.
Text messages
If you opt in to nightly reminders, we use your mobile number only to send those reminders and related service messages. We do not sell, rent, or share your mobile number or text-messaging opt-in consent with third parties or affiliates for marketing or promotional purposes. Reply STOP at any time to stop texts, or HELP for help.
Who we share it with
Only service providers that help us run MyBack9, under their own privacy and security terms: Stripe (payments), Supabase (data storage), Netlify (hosting), Twilio (text messages), our email provider, and, if enabled, Google and Meta for analytics. We don't sell your personal information.
How long we keep it
We keep your information while you have access to your workbook or membership, and as needed for legal, tax, and accounting purposes. You can ask us to delete it sooner.
Your choices
You can ask to access, correct, or delete your information at any time by emailing hello@myback9.com. You can turn off texts in the app or by replying STOP.
Health information
MyBack9 is a general fitness program, not a medical service. Please don't send us medical records or diagnoses.
Children
MyBack9 is for adults. We don't knowingly collect information from anyone under 18.
Changes
If we change this policy, we'll update the date above. Material changes will be posted on this page.
