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 · 13 June 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 including higher AI generation quotas with access to standard AI models.
  • Partner: Premium features including the highest AI generation quotas with access to advanced AI models and priority support.

Subscriptions are processed through RevenueCat and billed via the Apple App Store or Google Play Store. Subscriptions automatically renew at the end of each billing period unless cancelled at least 24 hours before the renewal date. You can manage or cancel your subscription through your device's app store settings. Refunds are subject to the policies of Apple or Google, as applicable.

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. By starting to use the paid features of Fiz inside that 14-day period, you expressly request that the service begins immediately and you acknowledge that you lose your right of withdrawal once the service has been fully performed.

Where you purchase a subscription via 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. To request a refund, use the App Store ("Report a Problem") or Google Play refund flow. For any other withdrawal or refund question, contact us at hello@joinfiz.com.


05/ 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.


06/ 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.


07/ 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 7 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.


08/ 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.
  • Spam, send unsolicited messages, or engage in any form of automated abuse.
  • 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.

09/ 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.

10/ 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.


11/ 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.


12/ Third-Party Services

Fiz integrates with third-party services including Apple HealthKit, Google Health Connect, RevenueCat, 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.


13/ 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.


14/ 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.


15/ 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 7, and that you assume responsibility for the consequences of your own physical activity.

Allocation of risk

The limitations in this Section 15 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.


16/ 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.


17/ 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.


18/ 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.


19/ 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.


20/ 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.


21/ 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.


22/ Content Moderation Appeals

If your content is removed or your account is suspended, you may appeal the decision by contacting us at hello@joinfiz.com within 30 days. Your appeal must include:

  • Your username and account email address.
  • A description of the content removed or action taken.
