RepStack

Terms of Use

Effective June 10, 2026

The short version

RepStack is a workout tracking app for iOS. Pay for Pro through Apple if you want it, cancel whenever you like, train sensibly, and understand that the app is a logbook — not a doctor or a coach with a license.

The app

RepStack is distributed through the Apple App Store for iOS devices. By downloading and using it you agree to these terms and to Apple's standard App Store terms. You may use the app for your own personal, non-commercial training.

Subscriptions and purchases

RepStack Pro is available as a weekly, monthly, or annual subscription, or as a one-time lifetime purchase. All payments are handled by Apple through your App Store account — we never see or store your payment details.

Not medical advice

RepStack tracks your training and suggests progressions, but it is not medical advice and its suggestions are not a substitute for a qualified professional. Consult a doctor or qualified trainer before starting or changing a training program, especially if you have any health conditions or injuries. You train at your own risk, and you are responsible for using weights and equipment safely.

Your data

Your workout data stays on your device (and optionally in your private iCloud). How we handle data is covered in the Privacy Policy. You are responsible for keeping a backup of anything important — for example by enabling iCloud sync or using the database export in Settings.

No warranty

RepStack is provided "as is", without warranty of any kind. We work hard to make it reliable, but we cannot guarantee it will be free of bugs, always available, or fit for any particular purpose. To the maximum extent permitted by law, we are not liable for any loss or damage arising from your use of the app, including loss of data or injury sustained while training.

Changes to these terms

We may update these terms from time to time. When we do, we will update this page and the effective date above. Continuing to use the app after a change means you accept the updated terms.
