Terms of Service

Last updated: August 10, 2026

1. Agreement to these Terms

These Terms of Service ("Terms") govern your access to and use of Metal Strength — the website at metalstrength.fit, the Android and iOS apps, the workout builder, the training-program library, workout tracking, the exercise library, the calculators, account features, and related pages and services (together, the "Service"). By accessing or using the Service, you agree to these Terms. If you do not agree, do not use the Service.

2. Operator and scope

The Service is operated by an independent developer based in France ("Metal Strength", "we", "us", or "our"). These Terms apply to the website, the mobile apps, and account features. They do not replace any mandatory terms that may apply through an app store, device platform, authentication provider, payment provider, advertising provider, or other third-party service.

3. What the Service does

Metal Strength is a training app. Depending on the part you use, and whether you are signed in, it lets you:

The exercise library, the calculators and the whole program list can be browsed without an account. Saved workouts, saved sessions, history, charts, progress photos and profile defaults require sign-in.

A large part of the Service is free. We also offer an optional paid tier, Metal Strength Premium, sold as an auto-renewing subscription — see section 4. We do not sell physical goods.

Training content (programs, set and rep schemes, exercise instructions and demonstration clips) is general reference material produced from established training principles. It is not a personalised coaching plan and is not supervised by a coach — see section 7.

4. Premium subscriptions

Metal Strength Premium is an optional paid subscription that unlocks additional features — for example the full training-program library, unlimited saved plans and bookmarks, your complete workout history rather than the most recent period, unlimited progress photos, the long-period statistics views, cloud-synced plan drafts, and removal of all advertising. It is offered as an auto-renewing monthly or annual plan. The price, billing period, and any promotional discount are shown before you confirm the purchase. Which features sit behind the subscription can change as the Service evolves.

Recording your training is free and is not rationed. A free account can run and save as many workouts as it likes, with no daily limit. What a free account gets is a shorter window on its own history: the app shows the most recent period (currently 90 days). Older records are retained, never deleted, they reappear if you subscribe, and a data export always contains everything we hold on you whichever plan you are on.

• Billing. On the website, payments are processed by PayPal under PayPal's own terms. In the mobile apps, subscriptions are sold through the platform store — Google Play on Android and the Apple App Store on iOS — and billed by that store to the payment method on your store account. In every case we never receive your full card or bank details. Your subscription renews automatically at the end of each billing period until you cancel.
• Cancelling. A subscription bought on the website can be cancelled at any time from your dashboard settings or from your PayPal account. A subscription bought in the app must be cancelled where the store manages it — Google Play subscriptions in the Play Store, App Store subscriptions in your Apple ID settings. There is no cancellation fee: billing stops, and Premium stays active until the end of the period you already paid for.
• Refunds and EU/UK withdrawal. If you are a consumer in the EU or UK, you have a statutory 14-day right of withdrawal from the day you subscribe. By starting Premium immediately you ask us to begin supplying it during that period; if you then withdraw within the 14 days, we refund the price minus a proportionate amount for the time already supplied. For a purchase made on the website, email hello@metalstrength.fit. For a purchase made through Google Play or the App Store, the refund is handled by that store under its own rules — contact the store first, and contact us if you need help. Beyond that right, payments already made are non-refundable except where the law provides otherwise.
• Price changes. We may change subscription prices. A change never affects a period you have already paid for — we will notify you in advance and the new price applies from a later renewal, so you can cancel first if you disagree.
• One entitlement, every platform. Premium is tied to your Metal Strength account, so an active subscription unlocks the same features on the website and in the apps. Cancelling with one biller does not cancel a separate subscription bought through another.

5. Eligibility

You must be at least 15 years old to create an account or submit personal data through the Service. If you are under 15, do not create an account or submit personal data unless a parent or legal guardian has provided the legally required permission. Because the Service does not currently offer a dedicated parental-consent flow, account creation is intended for users who are at least 15.

By using the Service, you confirm that the information you provide is accurate and that you are legally able to accept these Terms.

6. Your account

Creating an account is optional. When you create one, you must accept these Terms and our Privacy Policy. You can sign up with an email address and password or with a supported sign-in provider (Google on the website and in the apps; Sign in with Apple in the iOS app). You are responsible for maintaining the confidentiality of your login credentials and for activity under your account. Notify us promptly at hello@metalstrength.fit if you believe your account has been accessed without permission.

You may stop using your account at any time. You can delete individual saved workouts, sessions, lifts and photos in your dashboard. To delete the whole account, open Dashboard → Settings → Delete account or follow these instructions.

7. Fitness and training disclaimer

The Service is an informational fitness tool only. It does not provide medical advice, diagnosis, treatment, injury-prevention advice, or personalised coaching. Training programs, suggested exercises, set and rep targets, rest times, estimated calorie burn, strength tiers, percentiles, estimated one-rep max values, bodyweight ratios, and other outputs are general estimates based on formulas, templates and reference data. They may be incomplete, inaccurate, out of date, or unsuitable for your circumstances. You choose what to train and how hard; the Service does not supervise you.

Resistance training can involve serious risk, especially maximal or near-maximal lifting. Always train within your abilities, use proper technique and equipment, and seek advice from a qualified physician, healthcare provider, or coach before beginning or changing a training program. Stop training and seek help if you experience pain, dizziness, or unusual symptoms. Our Disclaimer forms part of these Terms.

8. Your content and saved data

Workouts and plans you build, saved sessions, lift entries, body and profile data, progress photos, messages, and other information you choose to submit remain yours. By submitting or saving content, you give us the limited permission needed to host, store, process, transmit, and display that content back to you, operate the Service, protect the Service, and respond to your requests. We do not use your training data or your photos to advertise, and we do not publish them.

You must not submit content that is unlawful, abusive, misleading, infringing, or that you do not have the right to provide. We do not sell your personal data. How we handle personal data is explained in the Privacy Policy.

Sharing your training with friends

Friends is optional and starts switched off; nothing about your training reaches another person unless you turn sharing on yourself, and you can turn it off, or remove a friend, at any time. What a friend can and cannot see — and in particular that the days you train, the loads you lift, your body measurements and your progress photos are never included — is set out in the Privacy Policy.

Please share carefully: while we control what the Service shows a friend, we cannot control what a person does with something they have already been shown. Choose who you connect with accordingly, and treat what a friend shares with you as private to them.

If you import data from another fitness app, you confirm the file is your own export and that you have the right to upload it. Imported entries become saved sessions on your account and are yours to edit or delete like any other; we do not verify their accuracy.

9. Photos and video uploads

Some features let you upload images or video:

• Progress photos are stored privately and are visible only to you. They are never public, never shared with other users, and never used for anything other than showing you your own history.
• Record submissions. If you submit a lift for the community record board, you upload a video of the lift and a photo or video of the weight, plus the details of the attempt. You confirm that you appear in — or hold the rights to — what you upload, and you give us permission to review it, and to publish the record details (such as the lift, the load and the name you provide) if it is accepted. We may decline or remove any submission, for any reason, including if it looks unsafe, edited, or misattributed.

Do not upload anything containing another person who has not agreed to it, anything unlawful, or anything you do not have the right to upload.

10. Acceptable use

You agree not to:

• use the Service for any unlawful, harmful, fraudulent, or abusive purpose;
• attempt to access another user's account, saved data, photos, or any non-public system;
• probe, scan, attack, overload, scrape, or disrupt the Service or its infrastructure;
• circumvent authentication, entitlement checks, rate limits, bot protection, consent tools, or security controls, or access paid features without an active subscription;
• bulk-copy the exercise library, the training programs, or other reference content, by hand or by automated means;
• submit malware, spam, false contact details, or automated form submissions;
• use Friends to harass anyone, to send unwanted requests at scale, or to guess, harvest, or publish other people's friend codes;
• choose a display name that impersonates another person, or that is offensive or misleading to the friends who see it;
• republish, sell, or otherwise pass on training information a friend shared with you, or keep using it after they have removed you or switched sharing off;
• upload an import file containing data that is not yours to import;
• interfere with advertisements or generate invalid ad impressions, clicks, or traffic;
• copy, resell, sublicense, or commercially exploit the Service without written permission;
• use the Service in a way that violates another person's rights or applicable law.

11. Intellectual property

The Service, including its name, branding, interface, design, text, software, training programs, exercise descriptions, illustrations, demonstration media, calculations, and compiled reference materials, is owned by us or our licensors and is protected by intellectual-property and other laws. These Terms do not grant you ownership of the Service, our branding, or our content.

You may use the Service for personal, non-commercial training purposes. You may not redistribute our programs or exercise content as your own, remove notices, reverse engineer the Service except where law permits it, or use our name, logo, or branding in a way that suggests endorsement without permission.

12. Third-party services, links, and advertising

The Service relies on third-party providers for hosting, security, authentication, database and file storage, email delivery, sign-in, payments, subscription management, and advertising. These include Supabase, Cloudflare, Resend, Google, Apple, PayPal and RevenueCat. Third-party services are governed by their own terms and privacy policies.

The website may display advertisements and links to third-party websites. We are not responsible for third-party content, products, services, security, or privacy practices. Advertising is provided through Google AdSense; see our Privacy Policy and Cookie Policy for information about advertising cookies and your choices. The mobile apps show advertising to free accounts, served by Google AdMob using your device's advertising identifier and subject to the consent described in the Privacy Policy. A Premium subscription removes advertising everywhere.

13. Mobile applications

The Metal Strength apps for Android and iOS provide the same account and the same features as the website, and these Terms cover your use of them. App-store providers (Google Play, Apple App Store) apply their own terms, privacy notices, billing and refund rules, and technical requirements. To the extent there is a conflict between these Terms and mandatory app-store terms for the app, the mandatory app-store terms apply for that app-store relationship.

The apps ask for device permissions only where a feature needs them — for example camera or photo access when you add a progress photo. You can decline, and the rest of the app keeps working.

14. Availability and changes to the Service

We provide the Service on an "as available" basis. We may update, improve, suspend, restrict, or discontinue any part of the Service at any time, including individual features, programs, or free allowances. We may also impose reasonable limits to protect security, prevent abuse, or comply with law. We do not guarantee that the Service will always be available, secure, uninterrupted, or error-free.

15. Disclaimer of warranties

To the fullest extent permitted by applicable law, the Service is provided "as is" and "as available" without warranties of any kind, whether express, implied, or statutory, including warranties of accuracy, reliability, fitness for a particular purpose, merchantability, non-infringement, availability, or that results will meet your expectations.

Nothing in these Terms limits any warranty, guarantee, or right that cannot lawfully be excluded under applicable consumer law.

16. Limitation of liability

To the fullest extent permitted by applicable law, we will not be liable for indirect, incidental, special, consequential, exemplary, or punitive damages; loss of profits, data, goodwill, or opportunity; training injury; or any loss arising from your use of, inability to use, or reliance on the Service.

Nothing in these Terms excludes or limits liability that cannot legally be excluded or limited, including liability for intentional misconduct, fraud, gross negligence where applicable, or mandatory French and EU consumer-protection rights.

17. Consumer rights

If you use the Service as a consumer, you may have mandatory rights under the laws of your country of residence. These Terms are not intended to reduce those rights. In particular, mandatory rules about digital services, unfair contract terms, data protection, and consumer remedies remain unaffected where they apply.

18. Suspension and termination

You may stop using the Service at any time. We may suspend or terminate your access, remove content, or restrict features if we reasonably believe that you breached these Terms, created risk for the Service or other users, violated law, or used the Service abusively.

Sections that by their nature should continue after termination, including intellectual property, disclaimers, limitations of liability, governing law, and dispute provisions, will continue to apply.

19. Changes to these Terms

We may update these Terms from time to time. When we make material changes, we will update the "Last updated" date and, where appropriate, provide additional notice. Your continued use of the Service after updated Terms take effect means you accept the updated Terms.

20. Governing law and disputes

These Terms are governed by the laws of France, without regard to conflict-of-law rules. If you are a consumer, mandatory protections and jurisdiction rules under the law of your country of residence remain unaffected. Disputes will be submitted to the competent courts, subject to any mandatory consumer jurisdiction rules that apply.
