These terms are the agreement between you and One Nexus Design for the Velin iOS app. Velin has no accounts and collects none of your workout data, so the agreement is short: it covers your license, the limits of the health data shown, and what each side is responsible for.
1. Acceptance and scope
These terms apply to the Velin iOS app distributed through the App Store and its home screen widgets (the “App”). By downloading, installing, or using the App, you confirm that you have read and accept these terms. If you do not accept them, stop using the App and delete it.
This agreement is between you and One Nexus Design, the App's developer (“we,” “us”). Please also read the Privacy Policy, which forms part of these terms.
If you are below the age of full legal capacity where you live, use the App only after a guardian has read and accepted these terms.
2. License and restrictions
Subject to these terms, we grant you a personal, non-exclusive, non-transferable, revocable license to install and use the App on Apple devices that you own or control, as permitted by the Apple Media Services Terms and Conditions.
You agree not to:
- decompile, reverse engineer, or disassemble the App, or attempt to derive its source code, except where applicable law expressly permits it;
- copy, rent, lease, resell, sublicense, or otherwise distribute the App;
- circumvent, remove, or damage technical restrictions, marks, or copyright notices in the App;
- call system services abnormally through automation, or use the App in ways that could harm the App, other users, or Apple's services;
- use the App for any purpose that violates applicable law or infringes the rights of others.
3. Health and safety
The App is not a medical device. Distance, pace, heart rate, heart rate zones, condition scores, goal progress, and trend projections shown in Velin are estimates and visualizations derived from existing data. They are not a medical diagnosis, treatment advice, or professional coaching, and must not be used to assess any health condition.
The values in the App come from records already stored in Apple Health. Their accuracy depends on the devices and sensors that produced them — iPhone, Apple Watch, or third-party hardware — and on how you wear and use those devices. We make no warranty as to the accuracy, completeness, or timeliness of that data.
Assess your own health before starting or changing a training plan, and consult a physician or qualified coach where appropriate. If you feel unwell while exercising, stop immediately and seek help.
Use the App in a safe environment. Looking at a screen while running or cycling is a distraction; give priority to traffic and your surroundings, and follow local rules for roads and venues.
You assume the risks inherent in physical activity. The App is a tool for recording and reviewing, nothing more.
4. Data sources and your content
The App reads the data you authorize from Health on a read-only basis and never writes to or modifies anything there. You can revoke that access at any time in system settings, after which the related features cannot display data.
Memory photos, notes, nicknames, avatars, and goal settings you add in the App (“your content”) are stored in the app container on your device. You keep all rights in your content, and because it is never uploaded, these terms give us no license to use, copy, or display it.
For the same reason, we cannot retrieve, export, or restore content from your device. Deleting the App, switching devices, or system failure can all cause loss, so keep your own device backups.
When you use sharing, you decide whether to share, with whom, and what the shared image includes — a route trace, for example — and you accept the consequences of that choice.
5. Requirements and third-party services
The App requires iOS 26 or later and needs existing workouts in Health to show anything. Weather, maps, and place names depend on a network connection and the relevant system permissions; without them, those features degrade or become unavailable.
The App uses Apple's system services, including HealthKit, WeatherKit, MapKit, Photos, and the App Store. Apple provides those under its own terms and policies, and we do not control their availability, content, or accuracy. Weather data is provided by Apple Weather, subject to Apple's data-source and attribution requirements.
Updates, changes, or discontinuation of system or third-party services may break parts of the App. We will adapt within reason but do not promise that any feature remains available indefinitely.
6. Fees and purchases
The current version of the App is provided free of charge and contains no in-app purchases or subscriptions.
If we introduce paid features later, pricing, payment, billing, renewal, and refunds are handled by the App Store under Apple's policies, and the terms will be shown in the App and on its App Store page before purchase. We never collect or store your payment details directly.
7. Intellectual property
The App and its name “Velin,” logo, icons, interface design, illustrations, motion, copy, typography, and code belong to One Nexus Design or the respective rights holders, and are protected by copyright, trademark, and other laws. These terms grant a license to use the App and transfer no ownership.
Third-party fonts, open-source components, and assets used in the App remain subject to their own licenses.
Do not use the App's name, logo, or interface for promotion, derivative products, or commercial purposes without written permission. Sharing workout cards the App generates, for personal purposes, is fine.
8. Disclaimers and limitation of liability
To the maximum extent permitted by applicable law, the App is provided “as is” and “as available,” without warranties of any kind, express or implied, including merchantability, fitness for a particular purpose, non-infringement, and any warranty of uninterrupted, error-free operation or preservation of data.
To the maximum extent permitted by applicable law, we are not liable for indirect, incidental, special, punitive, or consequential damages arising from your use of, or inability to use, the App — including data loss, disruption to a training plan, physical injury, or lost profits.
In any event, our aggregate liability under these terms is limited to the amount you actually paid for the App; if you paid nothing, it is limited to the minimum permitted by applicable law.
Some jurisdictions do not allow the exclusion of certain warranties or the limitation of certain liabilities. In those jurisdictions the limitations above apply to the greatest extent the law allows, and they do not affect your statutory consumer rights.
9. Termination
You may stop using the App and delete it at any time, which ends this agreement. Deleting the App also removes the local data stored on your device.
If you materially breach these terms, your license ends automatically and you must stop using and delete the App. Sections 7, 8, and 11, and any provisions that by their nature should survive, remain in effect after termination.
10. Apple-specific terms
This agreement is between you and us only, not with Apple. We, not Apple, are responsible for the App and its content, maintenance, and support.
- Apple has no obligation to furnish any maintenance or support services for the App.
- If the App fails to conform to any applicable warranty, you may notify Apple, and Apple will refund the purchase price, if any. To the maximum extent permitted by applicable law, Apple has no other warranty obligation with respect to the App.
- We are responsible for addressing third-party claims relating to the App, including product liability, failure to conform to legal or regulatory requirements, and claims under consumer protection or similar laws.
- If a third party claims that the App infringes its intellectual property rights, we are responsible for the investigation, defense, settlement, and discharge of that claim.
- You represent that you are not located in a country subject to a U.S. Government embargo or designated as a “terrorist supporting” country, and that you are not listed on any U.S. Government list of prohibited or restricted parties.
- Apple and its subsidiaries are third-party beneficiaries of these terms and, upon your acceptance, have the right to enforce them against you as a beneficiary.
11. Changes, governing law, and contact
We may update these terms as features change or the law requires, and will update the effective date at the top of this page. Material changes will be noted in release notes or in the App where appropriate. Continuing to use the App after an update means you accept the revised terms.
These terms are governed by the laws of the place where you reside, without reducing the mandatory rights you hold under local consumer protection law. The parties will first try to resolve any dispute amicably; failing that, it may be brought before a court of competent jurisdiction.
