These terms are the agreement between you and the individual developer identified on Velin's App Store product page, operating under the One Nexus Design brand. 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 the individual developer identified on the App's App Store product page, operating under the One Nexus Design brand (“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. Run-memory titles, notes, and photos can sync to your own private iCloud database; nicknames, avatars, goals, and Health caches remain local. You keep all rights in your content, and these terms give us no license to use, copy, or display it.
Apple and your Apple Account settings control iCloud sync. We cannot read, export, or restore the contents of your private iCloud database for you. Deleting the App does not automatically delete the run memories stored there; see our Privacy Policy for how to manage or permanently delete them. Keep appropriate device backups as well.
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 App is free to download. After initial setup, continued access to the full experience requires either a Velin Pro annual auto-renewable subscription or a lifetime unlock in-app purchase.
Eligible new subscribers may receive a 7-day free trial. When the trial ends, the annual plan automatically renews at the price shown by the App Store on the purchase screen and is charged to your Apple Account unless you cancel at least 24 hours before the current subscription period ends. You can manage or cancel the subscription in your App Store account settings.
The lifetime unlock is a one-time purchase and does not renew. Actual prices, taxes, and trial eligibility are shown on the App Store purchase confirmation screen. Apple handles payment and refunds under its policies. We do not directly collect or store your payment information.
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.
