Terms of Service

These terms are a binding agreement between you and Dynos (dynos.fit) (“Dynos”, “we”, “us”) governing your use of the Dynos mobile app and the dynos.fit website (together, the “Service”). By creating an account or using the Service, you accept these terms. If you do not accept them, do not use the Service.

Our Privacy Policy explains how we handle your data and forms part of this agreement.

You must be at least 18 years old to use Dynos, and you must be legally able to enter into this agreement. You agree to provide accurate information and to keep your login credentials secure. You are responsible for activity that happens under your account.

One person, one account. Do not share your account or let someone else use it.

This is the most important section of these terms.

• Dynos is not medical advice. It is a fitness tracking and workout-suggestion tool. It is not a medical device, it does not diagnose, treat, or prevent any condition, and nothing in it is a substitute for advice from a qualified physician, physiotherapist, or coach.
• Our suggestions are algorithmic. Workouts, weights, set and rep targets, recovery readings and similar outputs are produced automatically from the information you enter. No human professional reviews them, and no clinician has assessed your individual condition. They may be wrong for you.
• Consult a professional first. Talk to a doctor before starting or changing a training programme, especially if you are pregnant, recovering from injury or surgery, or have any cardiovascular, musculoskeletal, metabolic or other medical condition.
• You assume the risk of physical activity. Strength training involves inherent risk, including serious injury. You decide which exercises and loads to attempt. Stop immediately if you feel pain, dizziness, or discomfort, and seek medical help for anything that concerns you.
• Injury settings are a preference, not a safety system. Telling Dynos about an injury adjusts what it suggests. It does not make a workout safe, and it must not be relied on as a medical safeguard.
• Estimates are estimates. One-rep maxes, calorie figures, recovery percentages and progress trends are approximations derived from formulas, not measurements of your body.

To the fullest extent permitted by law, you use Dynos to train at your own risk.

You keep ownership of everything you put into Dynos: your training history, notes, custom exercises, routines, and your profile photo.

You grant us a limited, worldwide, non-exclusive, royalty-free licence to host, store, reproduce and display that content solely so we can operate the Service for you — for example, syncing it between your devices, backing it up, and rendering it in the app. This licence exists only to run the product. It does not let us publish your content, use it in marketing, or sell it, and it ends when you delete the content or your account.

You are responsible for what you upload. Do not upload anything unlawful, infringing, or that you do not have the right to share, and do not upload other people’s personal information. If you use the app’s sharing features, you are choosing to publish that content yourself, and this agreement does not govern what the receiving platform does with it.

Dynos is currently provided free of charge. We do not sell subscriptions or in-app purchases at this time, and no payment information is collected.

If we introduce paid features, we will publish the pricing and any additional terms that apply before you are charged, and paying will always be your choice. Purchases made through the App Store are also subject to Apple’s terms and its refund policy.

You agree not to:

• access other users’ data, or attempt to bypass the access controls that keep accounts separate;
• probe, scan, overload, or disrupt the Service or its infrastructure;
• reverse engineer, decompile, or attempt to extract source code, except where that restriction is prohibited by law;
• scrape or bulk-extract data from the Service, or use it to build a competing product;
• use the Service for anything unlawful, or to harass or harm anyone.

Responsible security research is welcome. If you find a vulnerability, report it to support@dynos.fit rather than exploiting it, and give us a reasonable chance to fix it before disclosing it.

The Service may link to third-party sites and services we do not control — for example an app store, a community forum, or a social platform you choose to share to. We are not responsible for their content, their practices, or their terms, and linking to something is not an endorsement of it. Your use of a third-party service is governed by that service’s own terms and privacy policy, not ours.

The Service also depends on infrastructure providers listed in our Privacy Policy. An outage or change at one of those providers can affect the Service.

The Service — including the app, the website, our software, design, branding, and the exercise library we supply — belongs to us or our licensors and is protected by intellectual property law. These terms give you a personal, limited, non-transferable, revocable licence to use the Service for your own training. They do not transfer any ownership to you.

We may change, suspend, or discontinue parts of the Service. Dynos is local-first, so your data stays on your device and the app keeps working offline, but syncing and account features depend on systems that can go down. We do not promise uninterrupted or error-free service.

If we make a material change to these terms, we will update this page and its date. Continuing to use the Service after a change means you accept the updated terms.

You can stop using Dynos at any time and delete your account from Profile → Permanently Delete Account.

Deletion is immediate and permanent. It removes your training history, your profile, your profile photo and your login. It is not a deactivation, there is no grace period, and we cannot restore your data afterwards. Export your data first if you want to keep it — Profile → Export Data produces a CSV of your workout history.

We may suspend or terminate your account if you materially breach these terms, or where we must do so by law. Sections that by their nature should survive termination — content licences already ended, disclaimers, limitation of liability, and governing law — survive it.

To the fullest extent permitted by law, the Service is provided “as is” and “as available”, without warranties of any kind, whether express or implied, including implied warranties of merchantability, fitness for a particular purpose, and non-infringement. We do not warrant that the Service will be uninterrupted, secure, error-free, or that its suggestions or calculations will be accurate or suitable for you.

The exercise library, technique descriptions, and training logic we supply reflect general strength-training practice at the time of writing. We cannot guarantee they reflect the most current sports science, or that any particular exercise or progression is appropriate for your body.

Some jurisdictions do not allow certain warranty exclusions, so parts of this section may not apply to you.

You agree to indemnify and hold harmless Dynos and its officers, employees and agents from any claims, damages, losses, liabilities and reasonable legal costs arising out of: your misuse of the Service; your breach of these terms; content you upload or share; or your violation of any law or of a third party’s rights.

This does not apply to claims arising from our own negligence or wilful misconduct, and it does not reduce any rights you have as a consumer that cannot be waived.

To the fullest extent permitted by law, we are not liable for indirect, incidental, special, consequential, or punitive damages, or for lost profits, lost data, or business interruption, arising from your use of the Service.

Nothing in these terms limits liability that cannot lawfully be limited — including liability for death or personal injury caused by negligence, for fraud or fraudulent misrepresentation, or any other liability that applicable law does not allow us to exclude. If you are a consumer, you keep all statutory rights that cannot be waived.

Where liability can lawfully be capped, our total aggregate liability arising out of the Service is limited to the greater of one hundred US dollars (USD 100) or the total amount you paid us for the Service in the twelve months before the event giving rise to the claim.

If you obtained the app from the Apple App Store, the following applies. This agreement is between you and us only, not with Apple, and we alone are responsible for the app and its content. Apple has no obligation to provide maintenance or support for the app. If the app fails to conform to any applicable warranty, you may notify Apple and Apple will refund your purchase price (if any); to the maximum extent permitted by law, Apple has no other warranty obligation with respect to the app. We, not Apple, are responsible for addressing any claims relating to the app, including product liability, legal or regulatory non-compliance, and consumer protection claims, and for handling any third-party claim that the app infringes intellectual property rights. You confirm you are not located in a country subject to a US Government embargo or designated as terrorist-supporting, and that you are not on any US Government restricted-parties list. Apple and its subsidiaries are third-party beneficiaries of this agreement and may enforce it against you.

These terms are governed by the laws of the State of Florida, United States, without regard to its conflict-of-law rules, and disputes will be handled by the state or federal courts located in Miami-Dade County, Florida, without affecting any mandatory consumer protections available to you where you live.

If a provision of these terms is held unenforceable, the rest remains in force. Our not enforcing a provision is not a waiver of it. You may not assign this agreement; we may assign it as part of a merger, acquisition, or sale of assets. These terms and the Privacy Policy are the entire agreement between us about the Service.
