The rules for using Simple Muscle.

1. The Service

Simple Muscle is a workout tracking tool for planning routines, logging sets, tracking rest, viewing history, and optionally syncing workout data through an account. The web dashboard and iOS app are available now. The iOS app is designed to work offline; app sync and restore require network access, a valid account session, and an active free trial or paid app plan. The web dashboard and MCP connection remain independently available.

2. Fitness and Health Responsibility

Simple Muscle is not medical advice, physical therapy, personal training advice, or a substitute for professional guidance. Exercise involves risk, including injury or death. You are responsible for exercising safely, choosing appropriate movements, weights, durations, and rest periods, and stopping if something feels unsafe.

Talk to a qualified healthcare or fitness professional before starting or changing an exercise program, especially if you have a medical condition, injury, pregnancy, or other concern. In an emergency, contact local emergency services.

3. Accounts and Sign-In

You can use the tracker without an account. If you create or use an account, you must provide accurate information, keep your sign-in method secure, and notify us if you believe your account has been compromised. Simple Muscle may support email one-time codes, Sign in with Apple, Google sign-in, and other methods we make available.

4. Sync, Restore, and Your Data

When account sync is enabled, your workout templates, completed sessions, preferences, and related records may sync to Simple Muscle servers for backup, restore, multi-device use, and connected features. You are responsible for the workout data you create and for reviewing any synced changes. Signing out does not automatically delete local data from your device.

Our handling of personal information is described in the Privacy Policy.

5. Connected AI Clients and Integrations

Simple Muscle may let you connect AI assistants, MCP clients, or other third-party tools. If you authorize a connection, the client may receive basic account identity and request workout plans, preferences, logged sets, and completed training history. It may also create, update, archive, or delete workout plans through the permissions shown during authorization. Completed training history remains read-only. You are responsible for choosing which clients to authorize, reviewing their outputs and requested actions, and deciding whether to follow any suggestion.

Third-party clients and sign-in providers are not controlled by Simple Muscle. Their own terms, privacy policies, data retention, and model-training practices and settings apply to their services.

6. Acceptable Use

You agree not to:

• Use Simple Muscle for unlawful, harmful, deceptive, or abusive purposes.
• Try to access another person's account, data, tokens, or connected clients.
• Interfere with, overload, scan, or attack the app, website, backend, or MCP endpoints.
• Bypass authentication, authorization, rate limits, security, or technical restrictions.
• Upload or transmit malware, exploit code, or content that infringes others' rights.
• Reverse engineer the service except where the law gives you a non-waivable right to do so.

7. App Content and Intellectual Property

Simple Muscle, including its design, software, exercise library, media, text, branding, and other content, is owned by us or our licensors. We grant you a personal, non-exclusive, non-transferable, revocable license to use Simple Muscle for your own fitness tracking in accordance with these terms.

You keep ownership of the workout data you create. You grant us the limited rights needed to store, process, sync, display, back up, restore, and operate that data for the service and for integrations you authorize.

8. Pricing and Paid Features

Simple Muscle offers a free offline workout tracker and paid iOS features such as account sync, cloud backup, and AI-assisted analysis of synced data. New accounts include a free trial of these features for a limited period (currently 7 days from account creation); when the trial ends, they pause until you subscribe, and the free tracker keeps working. The web dashboard and MCP connection can be used independently of an iOS subscription. Paid app features may be sold as auto-renewing subscriptions, including $5/month and $50/year plans. We will show the applicable price and terms before you buy. Purchases made through an app store, once available, may also be governed by that store's terms, billing rules, refund policies, and subscription controls.

9. Availability and Changes

We may change, suspend, or discontinue parts of Simple Muscle at any time. Offline tracking should continue without the server, but account sync, restore, sign-in, email delivery, connected clients, and other network features may be unavailable during maintenance, outages, provider issues, or changes to the service.

10. Suspension and Termination

You may stop using Simple Muscle at any time. We may suspend or terminate access to account, sync, or connected features if we believe you violated these terms, created risk for the service or others, or if required by law. To request account or synced data deletion, contact us at the email below.

11. Disclaimers

To the maximum extent allowed by law, Simple Muscle is provided "as is" and "as available." We do not promise that the app, website, sync service, workout content, connected clients, or generated suggestions will be uninterrupted, error-free, accurate, complete, secure, or suitable for your particular goals.

12. Limitation of Liability

To the maximum extent allowed by law, Simple Muscle and its owners, operators, affiliates, and service providers will not be liable for indirect, incidental, special, consequential, exemplary, or punitive damages, or for lost profits, lost data, personal injury, workout decisions, or service interruptions arising from your use of Simple Muscle. Some places do not allow certain limitations, so parts of this section may not apply to you.

13. Changes to These Terms

We may update these Terms and Conditions as Simple Muscle changes. The updated version will be posted on this page with a new last-updated date. Continued use after the updated terms take effect means you accept the updated terms.
