Terms of Service

Last updated: April 7, 2026

Welcome to Threwline. By creating an account or using our service, you agree to these Terms of Service ("Terms"). Please read them carefully.

1. Service Description

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.

2. Eligibility

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.

3. Account Registration

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.

4. SMS Messaging Terms

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:

  • Coaching messages: Responses to your meal logs, workout logs, questions, and other texts you send to your coach.
  • Proactive check-ins: Your coach may text you check-ins, nudges, reminders, and weekly summaries based on your activity and coaching state.
  • Account messages: Phone verification codes and service-related notifications.

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.

5. Opting Out of SMS

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.

6. Not Medical Advice

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.

7. AI-Generated Content

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.

8. Acceptable Use

You agree not to:

  • Use the service for any unlawful purpose.
  • Send abusive, threatening, or harmful content via SMS.
  • Attempt to reverse-engineer, exploit, or interfere with the service.
  • Share your account or allow others to use your phone number with our service.

9. Data and Privacy

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.

10. Account Termination

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.

11. Service Availability

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.

12. Limitation of Liability

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.

13. Changes to Terms

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.
