Welcome to Strength Journeys (strengthjourneys.xyz), a free, open-source web application for analyzing and visualizing your barbell lifting history. By using Strength Journeys, you agree to the following terms.
By accessing or using Strength Journeys, you agree to be bound by these Terms of Service. If you do not agree, please do not use the app.
Strength Journeys is not a medical service and does not provide medical advice. All content on this site — including articles, program recommendations, exercise descriptions, calculated metrics (such as estimated one-rep maxes), and video recommendations — is provided for general informational and educational purposes only. It is not a substitute for professional medical advice, diagnosis, or treatment.
Always consult a qualified healthcare professional before starting, changing, or intensifying any exercise or strength training program, especially if you have a pre-existing health condition, injury, or are returning from a period of inactivity. Never disregard professional medical advice or delay seeking it because of something you read or calculated on Strength Journeys.
Strength training carries an inherent risk of injury. You assume full responsibility for your own training decisions and physical wellbeing.
Strength Journeys is provided free of charge and on an "as is" basis, without warranties of any kind — express or implied. We make no guarantees regarding uptime, accuracy of calculations, or fitness of the service for any particular purpose. Use it at your own discretion.
Your lifting data lives in your own Google Sheet. Strength Journeys accesses it in your browser during your session. You remain the sole owner of your data. See our Privacy Policy for full details.
When you sign in with Google, Strength Journeys requests permission to access Google Sheets files you explicitly select. We will only access files you choose to connect, and will never access, modify, or share other files in your Google Drive. You can revoke this access at any time via your Google Account permissions.
The AI Lifting Assistant feature is opt-in and sends limited lifting metadata and bio data to an AI chat API to generate responses. AI-generated responses are for informational purposes only and do not constitute professional fitness or medical advice. No data from this feature is stored on our servers.
You agree to use Strength Journeys only for its intended purpose — personal fitness tracking and analysis. You may not attempt to reverse-engineer, scrape, or misuse the service in ways that harm other users or the application.
Strength Journeys is open-source software. The source code is publicly available. Use and contributions are subject to the project's open-source license.
To the fullest extent permitted by law, Strength Journeys and its developer shall not be liable for any indirect, incidental, or consequential damages arising from your use of the service — including any errors in calculated metrics, reliance on program recommendations, or injuries sustained while following any content found on this site.
We may update these Terms from time to time. Changes will be posted on this page with an updated date. Continued use of the app after changes constitutes acceptance of the revised Terms.
