1. Information We Collect
When you sign up for TrainSMS, we collect the following information directly from you:
- Phone number — required to deliver your workout texts, verify your identity via SMS code, and process your subscription.
- Name — to personalize your coaching experience.
- Age, height, and weight — used to calibrate your training program and nutrition guidance.
- Fitness goals and health notes — any information you voluntarily share about your current fitness level, goals, injuries, or health conditions.
- Email address (optional) — used to send workout summaries or account notifications if you choose to provide it.
- Workout replies — text responses you send back to TrainSMS (e.g., "Y" for completed, feedback on difficulty) are stored to improve your program week over week.
- Payment information — handled entirely by Stripe. We do not store your card number, CVV, or full payment details on our servers. Stripe retains payment data per their own privacy policy.
2. SMS Consent
You explicitly opt in to SMS messaging by entering your phone number on our sign-up page, verifying that number via a one-time SMS code, and completing a paid subscription checkout. By completing these steps, you consent to receive recurring automated SMS messages from TrainSMS related to your fitness program.
Message frequency varies based on the workout schedule you select (typically 1 to 7 messages per week). Standard message and data rates from your mobile carrier may apply.
To opt out at any time: reply STOP to any text message. You will receive one final confirmation, and no further messages will be sent. You may also reply HELP for support information.
