Terms of Service

Please read these Terms of Service ("Terms") carefully. They govern your use of Train Ultra. They include important provisions about arbitration of disputes (with a 30-day opt-out), a waiver of class actions, limits on our liability, and the law that applies to any dispute. By creating a Train Ultra account or using the Train Ultra iOS app or web dashboard, you agree to these Terms. If you do not agree, do not use the service.

1. Who we are

Train Ultra is operated by Spare Mile Studio, a business based in the State of Washington, USA. We can be reached at [email protected].

2. Eligibility and your account

You must be at least 13 years old to use Train Ultra. If you live in the European Economic Area, the United Kingdom, or Switzerland, you must be at least 16 unless local law sets a different minimum and you have parental consent.

You are responsible for keeping your account credentials (your email address and any sign-in code we send to it) confidential and for everything that happens under your account. Notify us promptly at [email protected] if you believe your account has been accessed without your permission.

3. Your content and data

You retain ownership of your activity data, training notes, goals, coach conversations, and anything else you provide to Train Ultra. By using Train Ultra, you grant us a worldwide, non-exclusive, royalty-free license to use that content solely to provide the service to you — generating titles, evaluations, coaching responses, training summaries, and other features, and routing the necessary fragments to the AI inference, text-to-speech, and other providers described in the Privacy Policy. This license ends when you delete your account, except for material we are required by law to retain (for example, billing records).

We do not sell your data, share it with advertisers, or use it to train third-party foundation models beyond the per-request inference needed to deliver the features you use. The full data-handling story is in the Privacy Policy.

4. AI output is not professional advice

Train Ultra’s AI features — titles, evaluations, coaching responses, and training summaries — are generated by large language models and can produce inaccurate, incomplete, biased, or otherwise imperfect output. Train Ultra is a training-companion product, not a substitute for a qualified human coach, medical professional, registered dietitian, or other licensed expert. If you have a health condition, injury, or medical question, or if you are recovering from one, consult a qualified human professional before acting on AI-generated suggestions. You use AI output at your own risk.

5. Acceptable use

You agree not to:

• Reverse-engineer, decompile, disassemble, or attempt to extract the source code or underlying ideas of Train Ultra.
• Abuse, harass, threaten, or impersonate others through coach conversations or any other surface in the service.
• Submit content that is unlawful, infringing, defamatory, or that you do not have the right to submit.
• Send automated traffic, scrape activity data, or exceed reasonable rate limits.
• Use the service in a way that violates the terms of service of Strava, Garmin, Oura, or any other connected provider.
• Use the service to violate any applicable law or regulation, including export-control and sanctions laws.
• Interfere with the service’s operation, security, or integrity (for example, by introducing malware, probing for vulnerabilities outside an authorized program, or attempting unauthorized access).

6. Subscriptions and billing

Train Ultra offers a free tier and one or more paid tiers (currently “Pro”). Pro pricing, the features included, and any free-trial terms are described on the Billing page in the web dashboard and in the in-app changelog. The free tier and the paid tiers may change over time; we will describe material changes in the in-app changelog.

Auto-renewal. Paid subscriptions automatically renew at the end of each billing period at the then-current rate until you cancel. You authorize Train Ultra (or, where applicable, the payment platform you used to subscribe) to charge your saved payment method for each renewal.

Cancellation. You may cancel at any time from Settings → Billing on the web dashboard. Cancellation takes effect at the end of the then-current billing period; you retain Pro access through that date.

Refunds. We do not refund partial billing periods. We may, at our discretion, refund the most recent billing period for billing errors, duplicate charges, or unauthorized use.

Free trials. Where we offer a free trial, the trial converts to a paid subscription at the end of the trial period unless you cancel before then. We will tell you when the first charge will occur before you start the trial.

Price changes. We may change subscription prices. Where we do, we will give you at least 14 days’ advance notice by email or in-app notice before the new price takes effect on your subscription, and you will have the opportunity to cancel before the new price applies.

Payment processing. Subscriptions are processed by Stripe. Stripe’s terms and privacy policy also apply to the payment relationship.

7. Service availability

Train Ultra is provided on a best-effort basis. We do not guarantee uninterrupted service, particular response times, or that AI features will always succeed. Connected third-party services — including Strava, Garmin, Oura, our AI-inference provider, our text-to-speech provider, our email provider, our payment processor, and Apple Push Notifications — may be unavailable at times, and we are not responsible for outages or changes in those services.

8. Termination

By you. You may stop using Train Ultra at any time. You may permanently delete your account from the iOS app (Settings → Delete Account) or the web dashboard (Settings → Delete Account). Deletion immediately removes the data we hold, per the Privacy Policy.

By us — immediate. We may suspend or terminate your account immediately, with or without notice, if (a) you violate the Acceptable Use clause; (b) you fail to pay amounts owed for a paid subscription; (c) we reasonably suspect fraud, abuse, or a security risk; (d) we are required to do so by a court order, law-enforcement request, or other competent authority; or (e) the account has been inactive for more than two years and we have given you at least 30 days’ advance email notice.

By us — for convenience. We may also terminate your access for any reason on at least 30 days’ advance email notice to the address on file.

Survival. Sections 3 (Your content and data — the limited license to retain anything required by law), 9 (Indemnification), 10 (Limitation of liability), 11 (Dispute resolution and arbitration), 12 (Governing law), and 16–19 (Force majeure, Severability, Assignment, Entire agreement) survive termination of these Terms.

9. Indemnification

You agree to indemnify, defend, and hold harmless Spare Mile Studio and its owners, employees, and agents from and against any claim, loss, liability, damage, cost, or expense (including reasonable attorneys’ fees) arising out of or related to: (a) your violation of these Terms; (b) content you submit to or share through Train Ultra; (c) your violation of any law or the rights of any third party (including but not limited to intellectual-property rights, privacy rights, and publicity rights); or (d) your misuse of the service. We will give you prompt notice of any such claim and will reasonably cooperate, at your expense, in the defense; you may not settle a claim that imposes any obligation on us without our prior written consent.

10. Limitation of liability

Service provided “as is.” To the maximum extent permitted by law, Train Ultra is provided as is and as available, without warranties of any kind, whether express, implied, or statutory, including warranties of merchantability, fitness for a particular purpose, title, non-infringement, and any warranty arising from course of dealing or usage of trade.

Cap on damages. To the maximum extent permitted by law, the total aggregate liability of Spare Mile Studio and its affiliates to you for all claims arising out of or relating to the service or these Terms, whether in contract, tort (including negligence), strict liability, or any other theory, is limited to the greater of (a) the total amount you paid Train Ultra in the twelve (12) months immediately preceding the event giving rise to the claim, or (b) fifty United States dollars (USD $50). This cap is in the aggregate across all claims, not per claim.

Excluded damages. To the maximum extent permitted by law, neither Spare Mile Studio nor its affiliates will be liable for any indirect, incidental, special, consequential, exemplary, or punitive damages, or for any loss of profits, revenue, data, training results, goodwill, or business opportunity, arising out of or related to the service or these Terms, even if we have been advised of the possibility of such damages.

Carve-outs. Nothing in these Terms excludes or limits our liability for (i) gross negligence, willful misconduct, or fraud; (ii) death or personal injury caused by our negligence to the extent applicable law does not permit such exclusion; or (iii) any other liability that cannot be excluded or limited under applicable law. Some jurisdictions do not allow the exclusion of certain warranties or limitation of certain damages, so some of the above limitations may not apply to you in full.

11. Dispute resolution and arbitration

Read this section carefully. Except as otherwise stated below, you and Spare Mile Studio agree that any dispute, claim, or controversy arising out of or relating to these Terms or to your use of Train Ultra (each, a “Dispute”) will be resolved by binding individual arbitration rather than in court, and that you and we are giving up the right to a jury trial and to participate in a class action or representative proceeding.

Informal resolution first. Before initiating arbitration, you agree to first contact us at [email protected] with a brief written description of the Dispute and your contact information, and to allow us 30 days to attempt to resolve it informally.

Arbitration rules and venue. If informal resolution fails, the Dispute will be submitted to binding arbitration administered by the American Arbitration Association (“AAA”) under its Consumer Arbitration Rules (the “Rules”), as modified by these Terms. The arbitration will be conducted by a single arbitrator. The seat of the arbitration is King County, Washington, USA, and the arbitrator will apply the substantive law of the State of Washington as described in Section 12 (Governing law). Where permitted by the Rules, hearings may be conducted by telephone or video conference. Judgment on the award rendered by the arbitrator may be entered in any court of competent jurisdiction.

Class-action and jury-trial waiver. You and Spare Mile Studio each waive any right to a trial by jury and any right to participate in or recover relief under any class, collective, consolidated, mass, or representative action with respect to a Dispute. The arbitrator may award relief (including monetary damages, injunctive relief, and declaratory relief) only in favor of the individual party seeking relief and only to the extent necessary to provide relief warranted by that individual party’s claim. If this class-action waiver is found to be unenforceable in your jurisdiction, then the entirety of this Section 11 (Dispute resolution and arbitration) is void with respect to you, and Section 12 (Governing law) will govern any Dispute.

Small-claims carve-out. Notwithstanding the foregoing, either party may bring an individual claim in a small-claims court of competent jurisdiction, provided the claim qualifies under that court’s jurisdictional limits (in Washington State, currently up to USD $10,000) and remains in that court. A claim removed or appealed beyond small-claims jurisdiction must instead be arbitrated as described above.

30-day opt-out. You may opt out of this Section 11 by sending an email to [email protected] within 30 days after you first create your Train Ultra account, with the subject line “Arbitration Opt-Out.” The email must include your account email address. If you opt out, neither you nor Spare Mile Studio will be required to arbitrate Disputes; instead, Section 12 (Governing law) will govern any Dispute. Opting out of arbitration does not affect any other provision of these Terms.

Other relief. Either party may seek temporary or preliminary injunctive relief in any court of competent jurisdiction to prevent the misappropriation or infringement of its intellectual-property rights or breach of confidentiality without first submitting the matter to arbitration.

12. Governing law

These Terms, and any Dispute, are governed by the substantive laws of the State of Washington, USA, without regard to its conflict-of-laws principles. To the extent Section 11 (Dispute resolution and arbitration) does not apply (for example, because you opted out, or because the class-action waiver was found unenforceable in your jurisdiction), the state and federal courts located in King County, Washington have exclusive jurisdiction over the Dispute, and you and Spare Mile Studio each consent to that jurisdiction and venue.

13. Changes to these Terms

We may update these Terms as the product evolves. Where we make material changes, we will announce them in the in-app changelog and bump the Effective date at the top of this page. For material changes, you will be asked to re-accept the updated Terms before continuing to use Train Ultra; we will tell you, in summary, what has changed. Continued use of Train Ultra after accepting the updated Terms constitutes your agreement to them. If you do not accept the updated Terms, you may stop using the service and delete your account at any time.

14. Force majeure

Neither party will be liable for any delay or failure to perform that is caused by an event outside that party’s reasonable control, including acts of God, natural disaster, war, terrorism, civil unrest, labor disturbance, pandemic, government action, internet or cloud-provider outage, or failure of third-party telecommunications or hosting services. The affected party will use reasonable efforts to mitigate the impact and resume performance as soon as practicable.

15. Severability

If any provision of these Terms is found by a court or arbitrator of competent jurisdiction to be unenforceable, that provision will be enforced to the maximum extent permitted, and the remaining provisions will continue in full force and effect. The exception is the class-action waiver in Section 11, whose unenforceability voids the entirety of that arbitration provision as described there.

16. Assignment

You may not assign or transfer your account or your rights or obligations under these Terms without our prior written consent; any attempted assignment in violation of this Section is void. We may assign these Terms in whole or in part, including in connection with a merger, acquisition, reorganization, sale of assets, or by operation of law, by providing notice to you. These Terms bind and benefit each party’s permitted successors and assigns.

17. Entire agreement

These Terms, together with the Privacy Policy, constitute the entire agreement between you and Spare Mile Studio regarding Train Ultra and supersede any prior or contemporaneous agreements or understandings (whether oral or written) on the same subject. No oral or written statement by us or our employees modifies these Terms.

18. Notice

To you. We will give you notice under these Terms by email to the address associated with your account, or, where appropriate, by in-app notice. You are responsible for keeping your email address current.

To us. You may give us notice by email to [email protected]. Notice is effective when delivered.

19. Relationship; no third-party beneficiaries

You and Spare Mile Studio are independent contractors. These Terms do not create an agency, partnership, joint venture, employment, or fiduciary relationship. These Terms do not create any third-party beneficiary rights.
