ZYM Legal
These Terms of Service govern your use of ZYM’s websites, web app, AI coaching features, community features, media uploads, group chat tools, and related services.
By accessing or using ZYM, you agree to these Terms of Service and our Privacy Policy. If you do not agree, do not use the service.
You must be at least 13 years old to use ZYM. If you are under the age of majority where you live, you should use ZYM only with permission from a parent or legal guardian. You are responsible for providing accurate registration information, maintaining the confidentiality of your credentials, and all activity that occurs through your account.
You may not impersonate another person, register accounts for others without permission, or attempt to access accounts or data that do not belong to you.
ZYM provides general informational, educational, and motivational content related to fitness, nutrition, wellness, and lifestyle. ZYM is not a doctor, dietitian, therapist, emergency service, or licensed medical provider. Using ZYM does not create a medical or professional care relationship.
You should not rely on ZYM for diagnosis, treatment, prevention of disease, emergency decisions, or other high-risk health matters. If you have chest pain, dizziness, fainting, shortness of breath, severe pain, neurological symptoms, injury, pregnancy-related concerns, or any urgent or worsening medical issue, stop and seek qualified medical or emergency care immediately.
ZYM uses AI systems to generate replies, analyze images, and suggest workouts, nutrition ideas, and wellness guidance. AI output may be incomplete, inaccurate, biased, outdated, or unsuitable for your circumstances. You remain solely responsible for how you interpret or act on any output from the service.
You agree not to use ZYM to:
ZYM has zero tolerance for objectionable content and abusive behaviour. Content of the kinds listed above is not permitted anywhere on ZYM, including posts, comments, profiles, group chats, and direct messages.
Every member can act on it directly from inside the app:
We review every report and act on it within 24 hours. Where a report is upheld we remove the content, and we suspend or permanently terminate accounts that breach these standards. You can also reach us at admin@zym8.com about anything you have reported.
You retain ownership of content you submit to ZYM, subject to any rights needed for us to operate the service. By posting, uploading, or sending content through ZYM, you grant us a non-exclusive, worldwide license to host, store, reproduce, process, adapt, and display that content solely as needed to run, maintain, secure, and improve the service.
You are responsible for ensuring that you have the necessary rights to upload or share any content you provide. You also understand that content shared in direct messages, group chats, or community areas may be visible to the people or groups you choose to share it with.
ZYM offers a free plan and paid plans (currently Core and Plus). Each plan sets daily allowances for live coach calls, call length, coach messages, camera use during live calls, form analyses, how long the coach retains memory of your training, and how adaptive your generated training plan is. The allowances that apply to your account at any moment are the ones shown on the plans screen in the app and at zym8.com/pricing; those pages read the same values the service enforces. We may change plan contents or prices, and will give notice of a price change before it takes effect for you.
Paid plans begin with a 3-day free trial. You provide a payment method at sign-up, but no charge is made until the trial ends. If you cancel at any point before the trial ends, you are not charged. If you do not cancel, the plan converts automatically to a paid subscription at the price shown at checkout, and the first charge is taken on the day the trial ends. Trials are limited to one per customer; we may decline a trial where we reasonably believe one has already been used.
Paid plans are currently offered only to customers in the United States. Two separate restrictions apply, and both must be satisfied:
If you are outside the United States, or on another storefront, the paid plans are shown but cannot be purchased. The free plan is available everywhere the app is. We do not guarantee availability in any particular country and may add or remove countries at any time. If you move your billing country or storefront after subscribing, we may be unable to continue the subscription.
Payments are processed by Stripe. We do not receive or store your full card number; Stripe handles card data as an independent payment processor under its own terms and privacy policy. Prices are in US dollars and exclude any taxes that may be added at checkout.
Subscriptions renew automatically — monthly or annually, matching the billing period you chose — until cancelled. Each renewal is charged to the payment method on file on the renewal date. If a payment fails, we may retry it, and access to paid features may be suspended or the subscription cancelled if it continues to fail.
You may cancel at any time, for any reason, through the billing portal linked from the plans screen in the app and on the web, or by emailing admin@zym8.com. Cancellation stops future renewals. It does not shorten the period you have already paid for: your paid features remain available until the end of the current billing period, after which the account returns to the free plan. Your account, training history and coach memory are not deleted by cancelling — only the paid allowances end. Coach memory retained beyond the free plan's retention window may be removed once you return to the free plan.
The 3-day free trial exists so you can evaluate a paid plan without paying for it. For that reason, charges are generally non-refundable, and cancelling part-way through a billing period does not produce a pro-rated refund for the remainder of that period.
We will, however, review a refund request and generally grant one where:
Request a refund by emailing admin@zym8.com from the address on your account, within 30 days of the charge, including the date and amount. We aim to respond within 5 business days. Approved refunds are returned to the original payment method through Stripe; how quickly the money appears is decided by your bank or card issuer, not by us. Where we refund a charge we may also end the corresponding access.
You can move between paid plans, and between monthly and annual billing, from the billing portal. Changes take effect immediately in both directions, and Stripe prorates: moving to a more expensive plan charges the difference for the remainder of the current period, and moving to a cheaper one issues a credit for the unused portion, applied against future invoices.
Changing plans during a free trial ends the trial and starts billing immediately. If you want to use the full trial before deciding, wait until it ends before switching.
Purchasing a second plan while one is already active is not supported, and we do not offer that option once you subscribe — use the billing portal to change plans rather than buying again.
Paid plans are sold through our website, not as an in-app purchase. If you begin from the iOS app you will be taken to app.zym8.com/plans in your browser to complete the purchase. The contract for a paid plan is between you and ZYM Tech, Co., and Apple is not a party to it. Apple does not process these payments and does not provide support, refunds or billing assistance for them — please contact us instead.
We may suspend or cancel a paid plan for non-payment, for a chargeback raised without first contacting us, or where an account breaches these terms. Where the allowances of a plan are exceeded, the relevant feature stops until the allowance resets; this is a limit, not a fault, and is not grounds for a refund.
ZYM may rely on third-party services for hosting, storage, identity verification, email delivery, AI inference, and related infrastructure. Your use of third-party sign-in, browsing, or external services may also be subject to those providers’ own terms and privacy practices.
We may suspend, limit, or terminate access to ZYM if we believe you violated these Terms, created risk for the service or other users, or engaged in misuse, fraud, abuse, or unlawful behavior. You may stop using ZYM at any time, and you may request account deletion through the app where available.
We may add, modify, pause, or discontinue features at any time. We do not guarantee that ZYM or any feature will always be available, uninterrupted, or error-free. Temporary outages, maintenance, data delays, model changes, and experimental features may affect how the service behaves.
ZYM is provided on an “as is” and “as available” basis to the fullest extent permitted by law. We disclaim warranties of merchantability, fitness for a particular purpose, non-infringement, accuracy, availability, and reliability. We do not promise that any content or AI output will meet your expectations or produce any particular outcome.
To the fullest extent permitted by law, ZYM and its operators will not be liable for indirect, incidental, special, consequential, exemplary, or punitive damages, or for lost profits, lost data, business interruption, or personal decisions made based on use of the service. Your use of ZYM and any actions you take based on its content are at your own risk.
Our collection and use of personal information is described in our Privacy Policy. By using ZYM, you acknowledge that we may collect and process information as described there.
We may revise these Terms from time to time. When we do, we will update the “Last updated” date at the top of this page. Continued use of ZYM after an update means the revised Terms will apply going forward.
If you have questions about these Terms of Service, contact ZYM at wangzijian0825@gmail.com.
