Effective date: 10 October 2026
These terms are an agreement between you and QYAI Tech Limited for the StepFast iOS app. Downloading or using StepFast means you agree to them. If you do not agree, do not use the app.
These terms are published at qyaitech.com. Email: qyairbx@outlook.com
We give you a personal, non-exclusive, non-transferable license to use StepFast on Apple devices you own or control, as allowed by the App Store rules that apply to you.
You may not sell, rent, or redistribute the app. You may not copy it except for the ordinary device copies iOS makes for your own use. You may not reverse engineer it except where the law does not allow this limit.
StepFast uses daily steps to guide a weight plan. Intermittent fasting is optional. The app has a free tier and a paid tier. The interface is in English. It requires iOS 17 or later.
StepFast does not use an account. Information the app keeps is stored on the phone. The StepFast Privacy Policy at qyaitech.com describes that storage, Apple Health, and Delete all data.
Use StepFast for your own wellness tracking.
Do not use the app if you are under 18.
Do not treat it as medical advice, a diagnosis, or emergency care.
Do not bypass the confirmation that you are 18 or older.
Do not break, overload, or interfere with the app.
Do not use Apple Health access for anything other than your own use of StepFast.
You may enter steps yourself if you do not connect Apple Health.
StepFast is a wellness app for adults 18 and older. It does not provide medical advice, and it is not a medical device. Talk with a doctor before you change how you eat or how much you walk, especially if you have a medical condition or you take medication.
Fasting is optional. The walking plan works without it. If you add fasting, the app asks about pregnancy or breastfeeding, diabetes, medicine that has to be taken with food, eating issues, and chronic conditions. If you answer yes, fasting stays off. You can turn fasting off, or redo the check, in Settings.
If the height and weight on file give a BMI under 16, StepFast does not start the program. If BMI is in the range 16 to 18.5, the plan is walking only and fasting stays off. These are product limits. They are not a medical clearance, and they are not a statement that walking or fasting is safe for you.
If you feel dizzy, shaky, or unwell during a fast, eat something and end the fast. If you have chest pain, faintness, or any medical emergency, contact your local emergency number. If thinking about food, eating, or your weight feels out of control, talk with a doctor or a mental health professional you trust.
StepFast does not change your fasting plan because your steps were low. A gentle note, when you leave it on, is a suggestion you can dismiss. It is not medical advice.
You can use the free tier without paying.
Paid access is an optional auto-renewable subscription from Apple, using StoreKit. Before you buy, the app shows the price and billing period that Apple supplies for the product you select, and any introductory offer Apple is displaying. Those details are Apple's. These terms do not set a price, a billing period, or a trial length.
If you subscribe:
Apple charges the payment method on your Apple Account.
The subscription renews, and Apple charges your Apple Account again, unless you turn auto-renew off in your Apple Account settings. Under Apple's subscription terms, auto-renew needs to be turned off at least 24 hours before the end of the current period.
You manage or cancel the subscription in iOS Settings, in your Apple Account subscriptions. Deleting the app, or using Delete all data, does not cancel it.
If you already subscribed with the same Apple Account, you can restore the purchase in the app.
Refunds are handled by Apple under Apple's policies. QYAI Tech Limited does not run a separate refund program and does not set its own refund window. To ask about a charge, use Apple's report-a-problem process for the App Store.
The App Store, Apple Health, and in-app purchases are also covered by Apple's terms and Apple's privacy policy. Apple is not the publisher of StepFast. We are not responsible for Apple's billing, for Apple Health, or for iPhone backups.
You may stop using StepFast at any time. Use Delete all data in Settings if you want the app's local file removed. Cancel a subscription in your Apple Account settings if you do not want it to renew.
We may change StepFast, change what is in the free tier or the paid tier, or stop offering the app. A change does not add a charge beyond what Apple shows for a subscription you still have. Information stored only on your phone stays there until you delete it or you delete the app.
We may update these terms. The new text will be posted at qyaitech.com, and the effective date at the top will change. If you keep using StepFast after that date, the updated terms apply from then on.
