Terms of Service

These terms govern your use of MacroStack AI ("the App"). By downloading or using the App you agree to them. If you do not agree, do not use the App.

Privacy policies: iOS · Android. Need help? Visit support.

1. License

We grant you a personal, non-exclusive, non-transferable license to use the App on devices you own or control, for your own personal, non-commercial use. You may not copy, modify, distribute, sell, or reverse engineer the App except where the law allows it regardless of these terms.

2. Subscriptions and Purchases

Full access to the App requires a paid subscription or a one-time lifetime purchase. All payments are processed by the store you installed the App from (Apple App Store or Google Play), and their terms also apply.

• Free trial. Subscriptions start with a 14-day free trial. The trial converts to a paid subscription automatically unless you cancel before it ends. Cancel anytime during the trial and you will not be charged.
• Renewal. Subscriptions renew automatically at the price shown at purchase until you cancel. Manage or cancel them in your App Store or Google Play subscription settings. Deleting the App does not cancel a subscription.
• Lifetime. The lifetime unlock is a one-time payment, not a subscription. It covers the App as it exists and reasonably evolves, for as long as we offer it.
• Refunds. Refunds are handled by Apple or Google under their policies. We cannot issue refunds directly.

3. Not Medical Advice

The App tracks nutrition and estimates calorie targets from the data you log. It is for general wellness purposes only. It is not a medical device and does not provide medical advice, diagnosis, or treatment. Calorie targets, AI coach replies, and food scan estimates can be wrong. Consult a qualified health professional before changing your diet, especially if you are pregnant, have a medical condition, or have a history of disordered eating. The App is not intended for children.

4. Acceptable Use

Do not abuse the App or its services. In particular, do not attempt to circumvent purchase verification or usage limits, probe or overload our servers, use the AI features to generate unlawful or harmful content, or use the App in any way that violates applicable law.

5. Your Data

Your logs stay on your device, and limited data is routed through our server only to power the AI features, as described in the iOS and Android privacy policies. You are responsible for keeping your own backups. We cannot recover data stored only on your device.

6. Availability and Changes

We may update, change, or discontinue features of the App over time, and we may suspend or terminate access for abuse of these terms. The AI features depend on third-party services and may be rate-limited or temporarily unavailable.

7. Disclaimer and Limitation of Liability

The App is provided "as is" and "as available", without warranties of any kind, express or implied, including fitness for a particular purpose and accuracy of nutritional data. To the maximum extent permitted by law, we are not liable for indirect, incidental, special, or consequential damages arising from your use of the App, and our total liability for any claim is limited to the amount you paid for the App in the twelve months before the claim.

8. Changes to These Terms

We may update these terms from time to time. The "Last updated" date above reflects the current version, and continued use of the App after an update means you accept the revised terms.
