These terms are an agreement between you and Boon Fay ("I", "me"), who runs The Six-Pack Stack (the coaching program and the Six-Pack Stack app), the Stack Score, Beyond the Label and the Fad Free Guide. By applying, buying or using any of them, you agree to these terms.
You must be 18 or older. The coaching program is a general fitness, nutrition and supplement education and accountability service. It is not medical care. Read the Disclaimer before you start.
The Six-Pack Stack is a 12-week, one-on-one online coaching program. It includes:
Your 12 weeks start on the date of your first Sunday check-in. Check-ins are due every Sunday. Missed check-ins don't extend the program.
Coaching is delivered online by email and messaging. There are no in-person sessions.
The price is shown on the checkout page when you buy. If you choose a payment plan, you agree to every installment on the schedule shown at checkout, and you authorize those charges to your payment method. If an installment fails and isn't paid within 7 days, I may pause your coaching until it is.
Payments are processed by Kit and its payment partners. I never see or store your full card details.
The Free Stack. After the quiz you get the first 2 weeks of your plan free: calories, meals and training. No payment details are needed.
The Full Stack. Weeks 3 to 12, meal rebuilds, Stack Check and the rest of the app are unlocked with an auto-renewing subscription bought in the app through Apple:
Prices are shown in your local currency in the app before you buy and may vary by country. Payment is charged to your Apple ID when you confirm the purchase, or when the free trial ends if you started one. The subscription renews automatically at the same price for the same period unless you turn off auto-renew at least 24 hours before the end of the current period. Your account is charged for renewal within 24 hours before the period ends.
Cancelling: manage or cancel any time in your iPhone Settings, under your name, then Subscriptions (or in the App Store app). Cancelling stops the next renewal; you keep access until the end of the period you paid for. If you cancel during the free trial, you won't be charged. Deleting the app or your account does not cancel a subscription by itself.
Refunds for app subscriptions are handled by Apple under its refund policy. You can request one at reportaproblem.apple.com.
Stack, the AI coach. Stack is an AI. It answers using your plan and my product verdicts, but it can be wrong and it is not medical advice. Check anything important with me (coaching clients) or your doctor. There are daily question limits.
Your use of the app is also covered by Apple's standard Licensed Application End User License Agreement. If anything in these terms conflicts with it, these terms apply to the extent the law allows.
If you complete the program and don't hit your goal in 12 weeks, I'll keep coaching you for free, for up to 12 more weeks, until you do.
The guarantee is extra coaching at no cost. It is not a cash refund.
Your goal is set together with me in your first week and confirmed in writing (email or message). It is either a target body weight or visible abs in your progress photos.
To qualify, you must:
The guarantee doesn't apply if you stop checking in, if your account is paused for missed payments, or if a medical issue stops you from following the plan (in that case we'll work out a fair pause together).
Coaching: because I start building your plan as soon as you join, coaching payments are not refundable. The guarantee above is how you're protected.
Beyond the Label: 30-day money-back guarantee. If it's not worth it to you, email me within 30 days of buying and I'll refund you in full. No questions asked.
If a download doesn't work or you can't access it, email me and I'll fix it.
If you think you were charged by mistake, email bfay@boonfay-pt.com before opening a dispute with your bank, and I'll sort it out.
Results depend on your effort, consistency, starting point and genetics. Any results I share (including my own and my clients') are not typical and are not a promise of what you'll get.
Your plans, Beyond the Label, the Fad Free Guide, my emails and videos are for your personal use. Please don't resell, share or republish them.
I may end coaching if you're abusive, if you share my materials, or if payments stay unpaid. You can stop at any time, but payments already made and installments you agreed to remain due.
To the fullest extent the law allows, I'm not liable for any injury, health problem, loss or damage from following (or not following) the plan, or for anything beyond the amount you paid me. You use the program at your own risk.
I may update these terms. The version in place when you buy applies to that purchase. These terms are governed by the laws of the State of California, USA.
