Welcome to Threwline. By creating an account or using our service, you agree to these Terms of Service ("Terms"). Please read them carefully.
Threwline is an AI-powered fitness coaching platform. You interact with your coach primarily via SMS text messaging. You can log meals, track workouts, get macro feedback, ask nutrition questions, and receive personalized coaching — all by texting our number. A web dashboard is also provided for viewing your progress and managing your account.
You must be at least 18 years old and have a valid US mobile phone number to use Threwline. By signing up, you confirm you meet these requirements.
You must provide accurate information when creating your account. You are responsible for maintaining the security of your login credentials. Notify us immediately if you suspect unauthorized access to your account.
By providing your phone number and checking the SMS consent box during onboarding, you expressly consent to receive recurring automated SMS messages from Threwline. This includes:
Message frequency:Varies. Expect 2-10 messages per day depending on your usage. On days you don't text, you may still receive 1-2 proactive check-ins.
Message and data rates may apply. Standard carrier messaging and data rates apply to all messages.
You may opt out of SMS messages at any time by texting STOP to our number. After opting out, you will receive one final confirmation message. You will no longer receive coaching messages, check-ins, or any other SMS from Threwline. You can still access your dashboard and data on the web.
To resume SMS coaching, text START to our number or update your preferences in your dashboard settings.
For help, text HELP to our number or email us at support@threwline.io.
Threwline provides AI-generated fitness and nutrition coaching. It is not a substitute for professional medical advice, diagnosis, or treatment. Always consult a qualified healthcare provider before starting any diet or exercise program, especially if you have existing health conditions. We are not liable for any health outcomes resulting from following coaching suggestions.
Coaching responses are generated by artificial intelligence. While we strive for accuracy, AI responses may occasionally contain errors. Nutritional estimates (calories, macros) are approximations, not exact measurements. Use your judgment and consult professionals for critical health decisions.
You agree not to:
Your use of Threwline is also governed by our Privacy Policy, which describes how we collect, use, and protect your data. We do not share or sell your phone number or personal data to third parties for marketing purposes.
You may delete your account at any time via the dashboard settings. We may suspend or terminate your account if you violate these Terms. Upon termination, your data will be deleted within 30 days.
We aim to keep Threwline available 24/7 but do not guarantee uninterrupted service. We may modify, suspend, or discontinue features at any time. We will provide reasonable notice for material changes.
Threwline is provided "as is" without warranties of any kind. To the maximum extent permitted by law, Threwline shall not be liable for any indirect, incidental, or consequential damages arising from your use of the service.
We may update these Terms from time to time. Material changes will be communicated via SMS or email. Continued use after changes constitutes acceptance of the updated Terms.
