Terms of
/ Service.
The agreement between you and Fiz. Plain-English ground rules for using the app, posting workouts, competing on leaderboards, and everything in between.
Last updated · 26 August 2026
01/ Acceptance of Terms
By creating an account on or using the Fiz application ("the Service"), operated by Fiz Global Ltd ("Fiz", "we", "us", or "our"), a company registered in England and Wales under company number 17237174, with registered office at 66 Paul Street, London EC2A 4NA, United Kingdom, you agree to be bound by these Terms of Service. If you do not agree to these terms, you must not use the Service. Your continued use of Fiz after any modifications to these terms constitutes acceptance of the updated terms.
02/ Eligibility
You must be at least 18 years of age to create an account or use Fiz. By using Fiz, you represent and warrant that you are at least 18 years old, that any information you provide (including your date of birth) is true and accurate, and that you have the legal capacity to enter into this agreement. We may verify your age at any time and may suspend or terminate accounts that we reasonably believe to have been created by users under 18. If we become aware that we have collected personal information from a person under 18, we will delete that information without undue delay.
03/ Account Registration & Security
You must provide accurate, complete, and current information when creating your account. You are responsible for maintaining the confidentiality of your account credentials and for all activity that occurs under your account. You must notify us immediately at hello@joinfiz.com if you suspect any unauthorised use of your account. Fiz is not liable for any loss arising from unauthorised account access.
04/ Subscription Plans & Billing
Fiz offers the following subscription tiers:
- Free: Access to core features including workout creation, score logging, and social features with limited AI generation quotas.
- Pro: Enhanced features for training for yourself, including higher AI generation quotas, community creation, and a higher limit on the number of programmes you can publish.
- Partner: Features for coaching other people, including the highest AI generation quotas, programme distribution to enrolled athletes, audience analytics, access to the Fiz partner web platform, and the ability to sell programmes through the Fiz marketplace (see Section 5). Partner is sold in bands, and each band carries a maximum number of athletes you may have enrolled in your programmes at one time (your "seat cap"). The bands, their seat caps, and their current prices are shown at the point of purchase. If you reach your seat cap you can continue to coach your existing athletes but must move to a higher band to enrol more.
All prices are shown to you inclusive of any applicable taxes before you confirm the purchase. Subscriptions automatically renew at the end of each billing period unless cancelled before the renewal date. We may change the price of a subscription, but a change will never affect a billing period you have already paid for, and we will give you reasonable notice before it takes effect.
How you are billed depends on where you subscribe
Fiz sells subscriptions through two separate channels, and which one applies to you determines how you cancel and how you get a refund:
- In the mobile app. The purchase is an in-app purchase billed by the Apple App Store or Google Play Store and managed on our side by RevenueCat. Cancel at least 24 hours before renewal through your device's app store settings. Refunds are handled by Apple or Google under their own policies, using the App Store "Report a Problem" flow or the Google Play refund flow.
- On the web. Partner subscriptions purchased on our website or partner platform are billed directly by us through Stripe. Cancel at any time from the billing portal linked in your partner settings, or by emailing us. Refunds for web purchases are handled by us, not by Apple or Google.
Right of withdrawal / EU & UK consumers
If you are a consumer resident in the European Union or the United Kingdom, you have a statutory right to withdraw from a paid subscription within 14 days of purchase, without giving any reason, under the EU Consumer Rights Directive (2011/83/EU) and the UK Consumer Contracts (Information, Cancellation and Additional Charges) Regulations 2013. Because Fiz is digital content supplied immediately, we ask you at checkout to expressly request that supply begins straight away and to acknowledge that you lose the right of withdrawal once the service has been fully performed. If you have not made that request, or supply has not yet begun, your 14-day right is unaffected.
Where you purchase through the Apple App Store or Google Play Store, Apple's and Google's own refund policies and cooling-off procedures apply and take precedence over our process, because they, not we, take the payment. Where you purchase from us directly on the web, we honour the 14-day right ourselves. Contact us at hello@joinfiz.com and we will refund you to your original payment method within 14 days of being told, less a proportionate deduction for any part of the service already supplied at your request.
Deleting your Fiz account does not cancel your subscription. If you are billed by Apple or Google, cancel in your app store settings. If you are billed by us through Stripe, cancel in the billing portal or email us, otherwise the subscription will keep renewing after the account is gone.
05/ Marketplace / Buying & Selling Programmes
Partners may offer their training programmes for sale on Fiz, either as a one-off purchase or as a recurring subscription to a programme. This section governs those transactions. It applies in addition to the rest of these Terms, and where it conflicts with another section, this section governs for marketplace transactions.
Who you are buying from
The Partner is the seller, not Fiz. When you buy a programme, the contract for that programme, covering its content, its quality, the coaching behind it, and anything the Partner has promised about it, is between you and the Partner. Fiz Global Ltd operates the platform, lists the programme, and facilitates the payment. We are not the author, publisher, or provider of the programme, we do not review or vet programmes before they are listed, and we do not endorse any Partner or their programming.
Payments are processed by Stripe. Funds from a sale settle to the Partner's own connected Stripe account, and the Partner's use of Stripe is additionally governed by the Stripe Connected Account Agreement. Fiz never receives or stores your payment card details.
Our commission
Fiz retains a platform commission on each marketplace sale, currently 3.5% of the gross transaction value, deducted automatically at the time of payment. The remainder, less Stripe's own processing fees, settles to the Partner. Stripe's fees are charged to the Partner's connected account under the Partner's agreement with Stripe, not by us. We may change the commission rate on at least 30 days' notice to Partners; a change never applies retroactively to a sale already made.
If you are buying / your rights
- Cooling-off. If you are a consumer in the UK or EU, the same statutory 14-day right of withdrawal described in Section 4 applies to a programme purchase, on the same terms. You are asked at checkout to consent to immediate access and to acknowledge the loss of that right once the programme has been fully supplied to you.
- Recurring programmes. You can cancel a recurring programme subscription at any time. Cancellation stops the next payment; it does not refund the period you are in, and your access runs to the end of that period.
- If the programme is not as described. Raise it with the Partner first. They are the seller and are best placed to fix it. If you cannot reach a resolution, contact us at hello@joinfiz.com and we will act as an intermediary. Where a programme was materially misdescribed, we may refund you and recover the amount from the Partner.
- Nothing here removes your statutory rights. If you are a consumer, your rights under the Consumer Rights Act 2015, including that digital content be of satisfactory quality, fit for purpose, and as described, apply to what you buy, and this section does not limit them.
If a programme goes away
A Partner may stop selling a programme, and a Partner's own subscription to Fiz may lapse. Neither of those things is intended to take away something you have already paid for. Where a Partner's subscription lapses, programme content they have published is frozen rather than deleted, and access already granted to you is preserved. Where a Partner delists or deletes a programme you hold a current paid grant to, we will use reasonable efforts to preserve your access for the period you paid for; if we cannot, you are entitled to a refund of the unused portion of that period, and you should contact us to arrange it.
We cannot promise that any programme remains available indefinitely, that a Partner keeps producing new content for a recurring programme, or that a Partner continues to respond to you. Those are commitments made by the Partner, not by Fiz.
If you are selling / your obligations
- You must have the right to sell everything in the programme, and it must not infringe anyone else's intellectual property. Content you did not write, video you do not own, and branded formats you are not licensed to use do not belong in a paid programme.
- Your listing must describe the programme accurately: its length, structure, equipment requirements, intended experience level, and what a buyer actually receives. You must deliver what it promises.
- You must not present programming as medical, physiotherapeutic, rehabilitative, or nutritional advice, or make health claims about outcomes. The Health & Fitness Disclaimer at Section 8 applies to everything sold through the marketplace.
- You are responsible for your own tax, for any professional registration or insurance your jurisdiction requires of a coach, and for the accuracy of the information you give Stripe during onboarding.
- You are responsible for handling your buyers' questions and complaints in good faith and within a reasonable time.
- Chargebacks, refunds, and payment disputes relating to your sales are your financial responsibility. We may deduct or recover from your future payouts any amount we refund to a buyer on your behalf, and any chargeback fee we incur as a result of your sale.
We may remove a listing, suspend marketplace access, or withhold a payout where we reasonably believe a programme breaches these Terms, infringes a third party's rights, is fraudulent, or presents a risk to buyers. Where we do so and the concern is not fraud, we will tell you why and give you an opportunity to respond under the appeals process in Section 23.
06/ User-Generated Content
You retain ownership of all content you create on Fiz, including workouts, activities, comments, images, collections, and programmes. By posting content on Fiz, you grant us a non-exclusive, worldwide, royalty-free licence to use, display, reproduce, and distribute your content within the Service for the purpose of operating and promoting Fiz. You are solely responsible for the content you post and must ensure it does not violate any third-party rights or applicable laws. We reserve the right to remove content that violates these terms.
07/ AI-Generated Content
Fiz uses Google Gemini API to generate workout and programme suggestions based on your text prompts. AI-generated content is provided for informational and inspirational purposes only. We make no guarantees regarding the accuracy, safety, or suitability of AI-generated workouts. You are solely responsible for reviewing, modifying, and using AI-generated content. AI-generated workouts should be adapted to your fitness level and physical capabilities. AI generation is subject to quotas based on your subscription tier.
08/ Health & Fitness Disclaimer
Fiz is a fitness tracking and workout-sharing platform. It is not a medical device and does not provide medical advice, diagnosis, treatment, or recommendations. The health data, workout suggestions, training metrics, scores, and educational information made available through the Service are for general informational purposes only and are not a substitute for professional medical advice.
Inherent risks of exercise
You expressly acknowledge that exercise carries inherent risks, including but not limited to muscle strain, sprain, ligament and tendon injury, joint injury, dislocation, fracture, cardiovascular events (including heart attack and stroke), rhabdomyolysis, dehydration, heat illness, fall, collision, equipment failure, and, in rare circumstances, serious or fatal injury. These risks are heightened in high-intensity workout formats including functional fitness and CrossFit®-style WODs, AMRAPs, EMOMs, hybrid racing (e.g. HYROX®), Murph, Hero WODs, benchmark WODs, Olympic lifting, gymnastics movements, prolonged endurance events, and any workout involving heavy load, complex skill, or maximal effort.
Consult your doctor before starting
You should consult your doctor or a qualified medical professional before starting any new exercise programme, materially increasing your training intensity, or attempting any workout on the Service, particularly if any of the following apply to you:
- You have any pre-existing medical condition (including heart, lung, joint, musculoskeletal, metabolic, neurological, or mental health condition).
- You are pregnant, postpartum, or trying to conceive.
- You are recovering from injury, illness, or surgery.
- You are taking medication that may affect your ability to exercise safely.
- You have not exercised regularly within the past six months.
- You are aged 50 or over, or otherwise have a higher cardiovascular risk profile.
Your responsibility for safety
You assume full responsibility for your own safety while using the Service. You agree to:
- Warm up before, and cool down after, every workout.
- Choose workouts, loads, and intensity appropriate to your current fitness level, experience, and any medical guidance you have received.
- Use correct technique and seek qualified in-person coaching where needed, particularly for high-skill movements such as Olympic lifts or gymnastics.
- Use safe, well-maintained equipment and a suitable training environment.
- Stop immediately and seek medical attention if you experience chest pain, pressure or tightness; faintness or dizziness; shortness of breath beyond normal exertion; severe joint or muscle pain; numbness; or any other warning sign.
- Not rely on Fiz for emergency medical assistance. In any emergency, call your local emergency services immediately.
Assumption of risk
To the fullest extent permitted by law, you voluntarily assume all risks of injury, illness, or property damage that may result from your participation in any activity referenced, recorded, suggested, scored, or generated through the Service, including AI-generated workouts and workouts created, shared, or remixed by other users. Fiz does not screen, verify, endorse, or guarantee the safety, accuracy, or suitability of any user-generated or AI-generated workout for any individual user.
Health data is not medical monitoring
Health data displayed via Apple HealthKit, Google Health Connect, or any other integration is provided for your convenience only. It must not be relied upon for medical monitoring, diagnosis, or treatment, and may be incomplete, delayed, or inaccurate.
Nothing in this Section 8 or anywhere else in these Terms limits or excludes our liability for death or personal injury caused by our negligence, for fraud or fraudulent misrepresentation, or for any other liability that cannot lawfully be limited or excluded.
09/ Acceptable Use
You agree not to:
- Use Fiz for any unlawful purpose or in violation of any applicable laws.
- Harass, bully, threaten, or intimidate other users.
- Post content that is obscene, defamatory, fraudulent, or infringes on intellectual property rights.

- Attempt to scrape, reverse-engineer, decompile, or otherwise extract the source code of the application.
- Interfere with or disrupt the Service, servers, or networks connected to the Service.
- Create multiple accounts for abusive purposes or to circumvent restrictions.
- Submit false or misleading scores, activity data, or leaderboard entries.
- Share your account credentials with others or allow others to access your account.
10/ Social Features & Community Guidelines
Fiz includes social features such as following other users, commenting on activities, liking content, and participating in challenges. When using these features:
- Be respectful and constructive in all interactions.
- Do not post comments that are abusive, discriminatory, or harmful.
- Respect other users' privacy settings and boundaries.
- Use the block feature to manage unwanted interactions.
- Report content or behaviour that violates these guidelines.
- We reserve the right to moderate, remove content, or suspend accounts that violate community guidelines.
11/ Intellectual Property
The Fiz application, including its design, branding, logos, movement library, scoring algorithms, UI components, and all associated intellectual property, is owned by Fiz Global Ltd. You may not copy, modify, distribute, sell, or lease any part of the Service without our written permission. The Fiz name, logo, and related marks are trademarks of Fiz Global Ltd.
12/ Privacy
Your use of Fiz is also governed by our Privacy Policy, which describes how we collect, use, and protect your personal information. By using Fiz, you consent to the data practices described in the Privacy Policy.
13/ Third-Party Services
Fiz integrates with third-party services including Apple HealthKit, Google Health Connect, RevenueCat, Stripe, Supabase, Resend, PostHog, Google Firebase Cloud Messaging, Cloudflare, Google Gemini API, and Google Geocoding API. Your use of these services is subject to their respective terms and privacy policies. Fiz is not responsible for the practices or content of third-party services. Links to external websites or services within Fiz do not imply endorsement.
14/ Leaderboards & Competitions
Fiz provides leaderboards, challenges, and competitive features. By participating, you agree to submit accurate and honest scores. We reserve the right to remove scores or disqualify participants who submit fraudulent, manipulated, or clearly inaccurate data. Leaderboard rankings are provided for entertainment and motivation – they do not constitute official competition results.
15/ Affiliate Programme
Fiz may offer affiliate code features that allow you to share product codes and links with your followers. When using affiliate features, you must comply with the following:
- You must clearly disclose affiliate relationships when sharing codes or links, using language such as "#ad", "#sponsored", "affiliate link", or similar clear and conspicuous disclosures, in compliance with FTC Endorsement Guides (16 CFR Part 255) and equivalent regulations in your jurisdiction.
- Disclosures must be made on every platform where you share affiliate codes (including Instagram, TikTok, YouTube, X, and any other social media).
- You must not make false or misleading claims about products associated with your affiliate codes.
- Self-referral fraud, including using your own codes for personal purchases, is prohibited.
Failure to properly disclose affiliate relationships may result in suspension of affiliate features, forfeiture of commissions, or account termination. We reserve the right to modify, suspend, or terminate affiliate features at any time.
16/ Limitation of Liability
Liabilities we do not exclude
Nothing in these Terms limits or excludes our liability for: (a) death or personal injury caused by our negligence; (b) fraud or fraudulent misrepresentation; (c) any breach of the terms implied by Sections 9 to 11 of the Consumer Rights Act 2015 (where applicable); or (d) any other liability which cannot lawfully be limited or excluded under English law.
Other liability
Subject to the paragraph above, and to the maximum extent permitted by law:
- Fiz Global Ltd, its directors, employees, agents, and affiliates shall not be liable to you for any indirect, incidental, special, consequential, punitive, or exemplary damages, including but not limited to loss of profits, loss of revenue, loss of business, loss of goodwill, loss of data, or loss of anticipated savings, whether arising in contract, tort (including negligence), breach of statutory duty, or otherwise, in connection with your use of the Service.
- Our total aggregate liability to you for all claims arising out of or relating to these Terms or your use of the Service shall not exceed the greater of (i) the total subscription fees you paid to us in the twelve (12) months immediately preceding the event giving rise to the claim, or (ii) one hundred pounds sterling (£100).
- You acknowledge that you use the Service voluntarily and at your own risk, that you have read and understood the Health & Fitness Disclaimer at Section 8, and that you assume responsibility for the consequences of your own physical activity.
Allocation of risk
The limitations in this Section 16 reflect a fair allocation of risk between you and us, taking into account the fact that the Service is offered at no charge or at a modest subscription fee, and that the commercial value of the benefit you receive would be materially different if we accepted broader liability exposure.
17/ Disclaimer of Warranties
The Service is provided on an "as is" and "as available" basis without warranties of any kind, either express or implied, including but not limited to implied warranties of merchantability, fitness for a particular purpose, and non-infringement. We do not warrant that the Service will be uninterrupted, error-free, secure, or free of viruses or other harmful components.
18/ Indemnification
You agree to indemnify, defend, and hold harmless Fiz Global Ltd, its officers, directors, employees, and agents from and against any claims, liabilities, damages, losses, costs, or expenses (including reasonable legal fees) arising out of or related to your use of the Service, your violation of these terms, or your violation of any rights of a third party.
19/ Termination
We may suspend or terminate your account at our sole discretion if you violate these terms, engage in abusive behaviour, or for any other reason we deem necessary to protect the Service or its users. You may delete your account at any time through the app. Upon termination, your right to use the Service ceases immediately, and all associated data will be permanently deleted in accordance with our Privacy Policy.
20/ Governing Law
These terms shall be governed by and construed in accordance with the laws of England and Wales. Any disputes arising from these terms or your use of the Service shall be subject to the exclusive jurisdiction of the courts of England and Wales.
21/ Changes to Terms
We reserve the right to modify these Terms of Service at any time. Material changes will be communicated through the app or via email. Your continued use of Fiz after changes are posted constitutes acceptance of the updated terms. If you do not agree with the changes, you must discontinue use and delete your account.
22/ Severability
If any provision of these terms is found to be unenforceable or invalid by a court of competent jurisdiction, the remaining provisions shall continue in full force and effect. The unenforceable provision shall be modified to the minimum extent necessary to make it enforceable while preserving its original intent.
23/ Content Moderation Appeals

- Your username and account email address.
