These Terms of Service ("Terms") are a binding agreement between you and Lintel Works LLC ("Lintel Works," "we," "us"), the company that operates Koers.
Please read Section 4 carefully. It describes the physical risks of following a training plan and the limits of what Koers can tell you. Sections 12 and 13 limit our liability to you.
By creating a Koers account or using the service, you agree to these Terms. If you don't agree, don't use Koers.
Koers is operated by Lintel Works LLC, a Nebraska limited liability company, 901 Farnam St, Unit 441, Omaha, Nebraska 68102, United States.

You must be at least 18 years old to create a Koers account. By creating one, you confirm that you are.
You are responsible for the accuracy of the information in your account, for keeping your password secure, and for everything that happens under your account. Tell us promptly at privacy@koers.app if you believe someone else has accessed it.
One account per person. Don't share your account or let someone else train on it — the coaching is built on your data and it becomes wrong when the data isn't yours.
Koers builds structured training plans for endurance cyclists, delivers those plans as workouts, reads your completed rides from connected devices, and provides written coaching about your training.
Koers is a fitness and performance tool. It is not a coach's license, a medical service, or a substitute for professional judgment where you need it.
We may change, add, or remove features. We may change how plans are generated or how coaching is written. If we make a change that materially reduces what you're paying for, we'll tell you before it takes effect.
This section matters more than the rest of this document. Read it.
Koers does not provide medical advice. Nothing Koers produces — training plans, workouts, coaching text, readiness or fitness metrics, or anything else — is medical advice, clinical diagnosis, treatment, or health assessment. All output is for fitness and performance purposes only. Consumer fitness devices, including power meters, heart rate monitors, watches, and bike computers, are not medical devices, and the data they produce is not clinical measurement.
Talk to a doctor before you start. Endurance training is physically demanding. Before beginning or substantially changing a training program, you should consult a qualified physician — particularly if you are over 40, have been inactive, are pregnant, or have or suspect any cardiovascular, respiratory, metabolic, musculoskeletal, or other medical condition.
You assume the risk. Cycling and structured endurance training carry inherent risks, including serious injury, cardiac events, heat illness, collision, and death. Riding outdoors adds traffic, road and trail surface conditions, weather, and other hazards outside anyone's control. You voluntarily assume all of these risks. You are solely responsible for deciding whether any prescribed session is appropriate for you on a given day, and for the manner and conditions in which you ride.
You are in charge, not Koers. A Koers plan is a recommendation based on incomplete information. We do not observe you, examine you, or know how you feel. Stop immediately and seek medical attention if you experience chest pain, undue shortness of breath, dizziness, faintness, or any symptom that concerns you. Do not complete a prescribed session because Koers asked for it. Skipping a workout is always a permitted outcome.
Data may be wrong. Device data can be inaccurate, incomplete, delayed, or missing. Threshold estimates, training zones, load calculations, and readiness indicators are estimates derived from that data and may be wrong. Do not rely on any Koers number as a measure of your health.
No guarantee of results. We make no promise that using Koers will improve your fitness, your performance, or your results in any event.
Koers connects to third-party services — device platforms, calendar providers, and sign-in providers — when you authorize it.
Those services are operated by other companies under their own terms and privacy policies. Your use of them is governed by their agreements, not ours. We aren't responsible for their availability, accuracy, security, or decisions, and a third party may change or discontinue its integration at any time, including in ways that break functionality in Koers.
You can disconnect any service from your account settings at any time.
Data we receive from connected services is handled as described in our Privacy Policy.
Koers is currently free to use while in beta. If we introduce paid plans, we will give you notice and you'll have the opportunity to decline before being charged.
Don't:
We may suspend or terminate accounts that violate this section.
Yours stays yours. You retain ownership of the training data, messages, and other content you provide or connect to Koers. You grant us a limited, non-exclusive license to host, process, transmit, and display that content solely to operate Koers and provide the service to you, and to our service providers for the same purpose. This license ends when you delete the content or your account, subject to the retention periods in our Privacy Policy.
Ours stays ours. Koers — the software, the design system, the plan-generation logic, the coaching voice and its written output, the name "Koers," and all associated trademarks — is owned by Lintel Works LLC and protected by intellectual property law. We grant you a limited, personal, non-transferable, revocable license to use Koers for your own training while your account is active. That's the only license granted; nothing else is implied.
Feedback. If you send us suggestions or feedback, we may use them without restriction, obligation, or compensation to you.
Koers uses automated systems, including large language models, to generate coaching text. See our Privacy Policy for how your data is processed in doing so.
Automatically generated text can be wrong, incomplete, or inappropriate for your situation. We review and constrain what the system produces, but we don't and can't review every message before you see it. Apply your own judgment, and see Section 4.
Koers coaching is not a licensed coach, a physician, a dietitian, or a therapist. If you're dealing with something that needs one of those, please talk to one. If you are in crisis, contact your local emergency services or a crisis line.
We aim to keep Koers running, but we don't guarantee uninterrupted or error-free service. We may suspend availability for maintenance, updates, security, or reasons outside our control. Features that depend on third-party services will be unavailable when those services are.
You can stop using Koers and delete your account at any time from account settings.
We may suspend or terminate your account if you breach these Terms, if we're required to by law, if your use creates a security or legal risk, or if we discontinue the service. Except where a breach or legal requirement makes it impractical, we'll give you reasonable notice and an opportunity to export your training data.
On termination, your license to use Koers ends. Sections 4, 8, 12, 13, 14, and 15 survive.
KOERS IS PROVIDED "AS IS" AND "AS AVAILABLE." TO THE MAXIMUM EXTENT PERMITTED BY LAW, LINTEL STUDIO LLC DISCLAIMS ALL WARRANTIES, EXPRESS, IMPLIED, STATUTORY, OR OTHERWISE, INCLUDING ANY IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, AND NON-INFRINGEMENT.
WE DO NOT WARRANT THAT THE SERVICE WILL BE UNINTERRUPTED, SECURE, OR ERROR-FREE, THAT DEFECTS WILL BE CORRECTED, OR THAT ANY DATA, METRIC, PLAN, OR COACHING OUTPUT WILL BE ACCURATE, COMPLETE, RELIABLE, OR SUITABLE FOR YOU.
Some jurisdictions don't allow the exclusion of certain warranties, so parts of this section may not apply to you.
TO THE MAXIMUM EXTENT PERMITTED BY LAW, LINTEL STUDIO LLC AND ITS OWNERS, EMPLOYEES, AND CONTRACTORS WILL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES, OR FOR ANY LOSS OF PROFITS, REVENUE, DATA, GOODWILL, OR BUSINESS INTERRUPTION, ARISING OUT OF OR RELATED TO YOUR USE OF KOERS, EVEN IF WE HAVE BEEN ADVISED OF THE POSSIBILITY.
TO THE MAXIMUM EXTENT PERMITTED BY LAW, OUR TOTAL AGGREGATE LIABILITY ARISING OUT OF OR RELATED TO THESE TERMS OR KOERS WILL NOT EXCEED THE GREATER OF (A) THE AMOUNT YOU PAID US IN THE TWELVE MONTHS BEFORE THE EVENT GIVING RISE TO THE CLAIM, OR (B) ONE HUNDRED U.S. DOLLARS ($100).
NOTHING IN THESE TERMS EXCLUDES OR LIMITS LIABILITY THAT CANNOT LAWFULLY BE EXCLUDED OR LIMITED, INCLUDING LIABILITY FOR DEATH OR PERSONAL INJURY CAUSED BY NEGLIGENCE, FRAUD, OR FRAUDULENT MISREPRESENTATION.
Some jurisdictions don't allow these limitations, so parts of this section may not apply to you.
You agree to indemnify and hold harmless Lintel Works LLC and its owners, employees, and contractors from any claims, damages, losses, liabilities, and expenses (including reasonable attorneys' fees) arising out of your use of Koers, your violation of these Terms, your violation of any law, or your violation of the rights of any third party.
These Terms are governed by the laws of the State of Nebraska, without regard to conflict of law principles.
Informal resolution first. If you have a dispute with us, email privacy@koers.app and give us 30 days to try to resolve it. Most things get sorted this way.
If we can't resolve it, the state and federal courts located in Douglas County, Nebraska will have exclusive jurisdiction, and you and we consent to personal jurisdiction there.
We may update these Terms. If a change is material, we'll notify you by email or in the app before it takes effect. Continuing to use Koers after that means you accept the updated Terms. The "last updated" date above always reflects the current version.
Entire agreement. These Terms and the Privacy Policy are the whole agreement between you and us about Koers.
Severability. If any provision is held unenforceable, the rest stays in effect.
No waiver. If we don't enforce a provision, that isn't a waiver of it.
Assignment. You can't assign these Terms. We may assign them to an affiliate or in connection with a merger, acquisition, or sale of assets.
Force majeure. Neither party is liable for failure to perform due to causes beyond its reasonable control.
