WeekCoach Terms of Use

Version: 1.1
Last updated: September 13, 2026
Effective: September 13, 2026

These Terms of Use (“Terms”) are a legal agreement between you and Feiou Su (“WeekCoach,” “we,” “us,” or “our”) governing your use of the WeekCoach iOS and iPadOS application and related sync service (together, the “Service”). By downloading, accessing, or using the Service, you agree to these Terms. If you do not agree, do not use the Service.

The Apple Standard Licensed Application End User License Agreement (“Apple Standard EULA”) also applies to the App. These Terms supplement the Apple Standard EULA. If they conflict about the license to the App, the Apple Standard EULA controls.

1. Eligibility

The App Store listing displays WeekCoach's current content age rating. That rating describes content suitability; it does not determine legal capacity. You may use the Service only if you can legally agree to these Terms where you live or a parent or legal guardian agrees on your behalf. Do not use the Service if applicable law prohibits you from doing so.

2. WeekCoach is a tracking tool, not medical care

WeekCoach helps you organize and record fitness or wellness plans. The Service, imported plans, starter plans, progress summaries, estimates, reminders, Coach responses, and AI-generated content are for general informational and organizational purposes only.

WeekCoach does not provide medical advice, diagnosis, treatment, rehabilitation, emergency services, or a guarantee that any exercise, plan, calorie estimate, metric, or AI output is safe, accurate, complete, or suitable for you. WeekCoach is not a physician, physical therapist, dietitian, trainer, or other licensed professional, and the Service does not create a clinician-patient or trainer-client relationship.

Physical activity carries inherent risks, including falls, overexertion, equipment failure, aggravation of an existing condition, serious injury, and, in rare cases, death. To the extent permitted by law, you knowingly accept the risks of choosing, modifying, or performing an activity recorded or displayed in the Service. You remain responsible for your environment, equipment, technique, intensity, supervision, recovery, and decision to begin, modify, stop, or skip an activity.

Consider consulting a qualified professional before acting on a plan, especially if you have a medical condition or injury, are pregnant, take medication, or are unsure whether an activity is appropriate. Stop and seek appropriate help if you experience pain, faintness, chest discomfort, severe shortness of breath, or other concerning symptoms.

The Service does not continuously monitor you, your surroundings, vital signs, form, or equipment; it does not verify that an activity was performed correctly; and it cannot detect or respond to an emergency. Do not use WeekCoach for an emergency or as a safety-monitoring system. Contact local emergency services when needed.

3. AI and imported content

WeekCoach can organize plans you import and, if eligible and configured, can use Apple Intelligence or a compatible Chat Completions endpoint you connect with your own API key. AI output can be inaccurate, unsafe, incomplete, outdated, biased, or inconsistent. It may misunderstand your request or your recorded data. AI output is probabilistic and may differ even when the input is similar. We do not pre-screen, independently verify, endorse, or professionally supervise imported plans, starter plans, third-party content, or AI output. You must review every plan and response before relying on it, and you assume responsibility for decisions or activities based on it.

WeekCoach does not host a model or include third-party AI usage. When you configure your own API connection, verification sends your key and a short test message to the entered endpoint; it may incur provider charges. Subsequent AI requests send the relevant plan and conversation context directly to that provider. Apple Health summaries require a separate, withdrawable opt-in that is off by default. Connecting a key does not grant that Health permission.

Use only a provider you are authorized to access and that is available under the rules applicable to your location. The provider's terms, privacy practices and charges apply. Protocol compatibility and a successful connection test do not establish regulatory approval, endorsement, or the accuracy or safety of its output. These disclosures do not waive rights or obligations that cannot lawfully be waived.

Copy-and-paste handoffs and external links are actions you control. Review a progress report before sharing it because it can contain fitness, personal, or Apple Health summaries. You choose the recipient and are responsible for confirming that the recipient is appropriate and that you have permission to disclose the information.

4. Your content and permissions

“Your Content” means plans, prompts, notes, metrics, messages, adjustments, and other material you enter, import, or create through the Service. You retain any rights you have in Your Content.

You grant us a limited, non-exclusive, worldwide license to host, copy, transmit, format, and process Your Content only as needed to operate, secure, support, and improve the Service consistent with our Privacy Policy. This license ends when the relevant content is deleted from our systems, subject to reasonable deletion processing, backups, legal retention, and content that has been de-identified or aggregated.

You represent that you have the necessary rights to use and import Your Content and that doing so does not violate law, confidentiality obligations, intellectual-property rights, or another service's terms. You are responsible for the accuracy of information you record and for maintaining your own copy of important plans or records. Do not submit another person's personal or health information without a lawful basis and any required permission. Do not use the Service as the only repository for information you are legally required or operationally unable to lose.

5. Accounts and sync

The App creates a random account identifier to support the local-first experience and a possible later upgrade to sync. You can use the core tracker without Sign in with Apple. Cloud content sync requires WeekCoach Pro and Sign in with Apple.

You are responsible for maintaining control of your device, Apple ID, and any credentials you add. Notify us promptly if you believe your synced account is compromised. Sync is a convenience, not a guaranteed backup. Conflicts, offline work, provider outages, software defects, or user deletion can cause delayed, duplicated, or lost data. Keep an independent copy of information you cannot afford to lose. To the extent permitted by law, activity performed through your device, Apple ID, or credentials will be treated as authorized until you notify us of compromise, and we are not responsible for loss caused by your failure to secure them.

You may request account deletion as described in the Privacy Policy. Deleting local data or the App does not necessarily delete cloud data, purchase history, or Keychain items.

6. Purchases and WeekCoach Pro

When offered, WeekCoach Pro is an in-app purchase that unlocks the features described on the purchase screen at the time of purchase. The App Store is the source of truth for product type, price, taxes, currency, payment terms, purchase availability, and Family Sharing. Apple processes the transaction, while RevenueCat helps WeekCoach verify and restore the entitlement.

The purchase unlocks WeekCoach functionality; it does not include third-party AI usage, an AI API key, Apple hardware, internet access, or third-party fees. AI and sync features can depend on device compatibility, permissions, provider availability, and configuration.

If the App Store describes the product as a “one-time purchase,” that describes the billing model, not a promise that the Service, every current feature, every third-party integration, or compatibility with every future device or operating system will remain available forever. We may replace or retire features for security, legal, technical, or platform reasons, subject to applicable law and the commitments shown at purchase.

Purchases, billing, and refunds are governed by the terms and policies shown by Apple. Use Restore Purchases in the App to ask Apple and RevenueCat to restore an eligible entitlement. Nothing in these Terms limits mandatory consumer rights.

7. License and acceptable use

Your license to install and use the App, including applicable device, account, Family Sharing, and transfer rules, is governed by the Apple Standard EULA and Apple's Usage Rules. These supplemental Terms govern WeekCoach-specific conduct and services.

You may not:

8. Our intellectual property

The Service, including its software, design, branding, mascot, text, and other materials supplied by us, is owned by us or our licensors and is protected by applicable law. Except for the limited license above, no rights are granted to you. Third-party names and marks belong to their respective owners and do not imply endorsement.

If you send suggestions or feedback, you allow us to use them without restriction or compensation, but you are not required to provide feedback.

9. Third-party and Apple services

The Service relies on or can connect to services such as Apple, Supabase, RevenueCat, our self-hosted FeiouTelemetry analytics infrastructure, and an AI provider you choose. Third-party services are governed by their own terms and privacy policies. We do not control and are not responsible for their content, security, availability, accuracy, decisions, changes, data handling, or charges. A link, integration, or compatibility statement does not mean that we endorse, control, or guarantee the third party. You must comply with all third-party terms that apply to your use of the Service, including your Apple, network, and AI-provider agreements.

The Apple Standard EULA is the source of truth for the relationship among you, Apple, and WeekCoach concerning the App license, maintenance, warranties, product and intellectual-property claims, legal compliance, and Apple's third-party-beneficiary rights. Nothing in these supplemental Terms changes or expands Apple's obligations. You must also comply with other third-party terms that apply to services you choose to connect.

10. Changes, availability, and termination

We may improve, update, suspend, or discontinue parts of the Service. We will provide notice when reasonably practicable if a change materially reduces a paid feature, subject to security, emergency, legal, and third-party platform needs. Features may not be available in every country, language, device, or OS version.

We are not responsible for delay or failure caused by circumstances reasonably beyond our control, including natural disasters, fire, war, civil disturbance, labor disputes, internet or power failure, cyberattack, government action, App Store or cloud-provider outage, or a third party's change to an API, operating system, policy, or service. This does not excuse obligations that cannot legally be limited.

You may stop using the Service at any time. We may suspend or terminate access if you materially or repeatedly violate these Terms, create legal or security risk, or misuse the Service. Where appropriate, we will give notice and a reasonable opportunity to correct the issue. Sections that by their nature should survive termination will survive, including ownership, disclaimers, liability limits, and dispute terms.

11. Disclaimers

To the maximum extent permitted by law, you use the Service at your own risk. The Service is provided “as is,” “as available,” and with all faults. We disclaim all warranties, express, implied, or statutory, including merchantability, satisfactory quality, fitness for a particular purpose, title, accuracy, quiet enjoyment, non-infringement, and any warranty arising from course of dealing or usage of trade.

We do not warrant that the Service will be uninterrupted, secure, error-free, compatible with all devices, or preserve or synchronize all data. We do not warrant the safety, suitability, accuracy, completeness, timing, or results of a fitness plan, starter plan, reminder, metric, calorie or progress estimate, Coach response, AI output, third-party service, or user-entered information. We have no duty to monitor an activity, review imported content, correct third-party or AI output, or warn you of a condition that the Service does not actually detect.

Some jurisdictions do not allow certain warranty exclusions, so some of this section may not apply to you. Any warranty required by law is limited to the shortest duration and narrowest scope the law permits.

12. Limitation of liability

To the maximum extent permitted by law, WeekCoach and its owner, affiliates, licensors, and service providers will not be liable for indirect, incidental, special, consequential, exemplary, or punitive damages, or for lost data, profits, goodwill, business interruption, personal records, or the cost of substitute services, arising from or related to the Service, even if advised that such damage is possible. This exclusion applies to claims arising from use of or inability to use the Service, an activity or plan, AI or imported content, an inaccurate estimate, unauthorized account access, data loss or sync conflict, or a third-party service.

To the maximum extent permitted by law, our total liability for all claims relating to the Service will not exceed the greater of (a) the amount you paid for WeekCoach during the 12 months before the event giving rise to the claim or (b) USD $50.

The exclusions and cap apply regardless of the legal theory and even if a limited remedy fails of its essential purpose. They do not exclude liability that cannot legally be excluded, including liability for fraud, willful misconduct, or personal injury to the extent applicable law prohibits its exclusion. Consumer-protection rights remain unaffected.

13. Indemnification

To the extent permitted by law, you will defend, indemnify, and hold harmless WeekCoach, its owner, affiliates, licensors, and service providers from third-party claims, liabilities, damages, judgments, losses, and reasonable legal costs arising from: (a) Your Content; (b) your unlawful or unauthorized use of the Service; © your material breach of these Terms; (d) your violation of another person's rights; or (e) your use of an AI provider, API key, or other third-party service in violation of its terms.

This obligation does not apply to the extent a claim was caused by our gross negligence, willful misconduct, or breach of these Terms, or where indemnification by a consumer is prohibited by law. We may control the defense of an indemnified claim, and you will reasonably cooperate. You may not settle a claim in a way that admits fault by or imposes an obligation on us without our written consent.

14. Governing law, disputes, and time to bring a claim

The Apple Standard EULA supplies the governing-law and forum rules for the App license. For a claim arising only from these supplemental Terms or a WeekCoach-operated service, mandatory law and the courts with lawful jurisdiction apply.

Before filing a formal claim, you and WeekCoach agree to try in good faith to resolve the issue by emailing support@feioustudio.com. This does not prevent either party from seeking urgent relief or using a small-claims or consumer process when available. The Apple Standard EULA may specify additional law and forum rules for the App license.

To the extent permitted by law, a claim relating to the Service must be filed within one year after the claim arose; otherwise, it is permanently barred. This contractual period does not apply where law requires a longer period or does not allow the period to be shortened.

15. Changes to these Terms

We may update these Terms to reflect changes to the Service, providers, or law. We will update the date above and provide additional notice in the App for material changes. Changes apply prospectively. If you do not agree to revised Terms, stop using the Service.

16. General terms

These Terms, the Privacy Policy, and the Apple Standard EULA are the entire agreement about the Service and supersede earlier understandings about it. If a provision is unlawful or unenforceable, it will be enforced to the maximum extent permitted and the remaining provisions will remain in effect. A failure to enforce a provision is not a waiver.

You may not assign these Terms without our written consent. We may assign them in connection with a merger, acquisition, reorganization, sale of assets, or by operation of law, subject to applicable privacy and consumer-protection requirements. Headings are for convenience only. Electronic notices and records satisfy written-notice requirements to the extent permitted by law.
