Acceptance of Terms

By downloading, installing, or using Iron Flow, you agree to these terms. If you don't agree, don't use the app.

What Iron Flow is

Iron Flow is a personal workout-tracking app for iOS and macOS. You may use it to record, analyze, and review your fitness data for personal, non-commercial purposes.

Account (optional)

Iron Flow works fully offline without an account. You can also Sign in with Apple to enable cross-device sync and cloud backup. By signing in, you authorize us to store your training data, profile preferences, and body metrics in our backend (Supabase) on your behalf, as described in our Privacy Policy.

You are responsible for safeguarding access to your Apple ID. We are not liable for activity carried out on your account by anyone you've granted access to.

Your data and your responsibility

• All data you enter is yours.
• When you sign in, your data is also stored in our backend so it can sync. You can delete your account at any time from Profile → Account Settings → Delete Account, which permanently removes your cloud data within 24 hours.
• When you don't sign in, your data lives only on your device. You are responsible for backing up your device. We are not responsible for data loss caused by device failure, accidental deletion, or app uninstall.
• The in-app Export feature lets you download your training history as CSV at any time.

Subscriptions and payments

Iron Flow is currently free. If we introduce paid features or subscriptions in the future, those will be governed by additional terms presented at the point of purchase via Apple's App Store. Apple handles all billing.

Acceptable use

Don't:

• Reverse engineer the app or attempt to circumvent security measures
• Resell, rent, or sublicense the app
