Terms

Effective 28 October 2026.

These terms are an agreement between you and Generative Chaos LLC, 5900 Balcones Drive #33409, Austin, TX 78731, United States (“we”, “us”), for the Jaksa app, its coach, and this website, jaksa.run (together, “Jaksa”). By making an account or using Jaksa you accept them. Our privacy page is part of them. Questions go to hello@jaksa.run.

Running is at your own risk

Jaksa is not a doctor, and nothing it says is medical advice. The coach is a computer-generated voice. Its suggestions — pace, effort, heart-rate zones, training plans, rest — are general fitness guidance produced automatically, not a diagnosis, a prescription or a professional assessment of you.

• See a doctor before you start training, or before you change how hard or how much you train, especially if you have a heart, lung or other medical condition, are pregnant, take medication, or have not exercised in a while.
• Stop at once if you feel unwell — chest pain or pressure, dizziness, faintness, unusual shortness of breath, palpitations, or pain — whatever the coach is saying, and get medical help if you need it.
• You decide where, when, how fast and how far you run. Watch the road, traffic, the weather and your surroundings, not the app. Keep the volume low enough to hear what is around you.
• Running carries a real risk of injury, illness and, rarely, death. You take that risk yourself.

The numbers may be wrong

Heart rate comes from your AirPods or your watch, position, pace and distance from GPS, height from the phone’s sensors and maps, and the weather from an outside service. Any of them can be wrong, late or missing: GPS drifts under trees and between buildings, and earbuds lose contact with the skin. The coach can mishear you, misread the numbers, or say something simply untrue. Do not rely on Jaksa for anything that matters to your health or safety.

Your account

You must be at least 16. You sign in with Apple, Google or Microsoft, and you are responsible for everything done through your account. Accounts are personal and may not be shared, sold or transferred.

Your workouts

Your workouts, notes and plans stay yours. You let us store, process and show them, and send them to the services that help us run it, as the privacy page describes, as far as running Jaksa for you needs — including to Strava, when you connect it.

What you may not do

Use Jaksa for anything unlawful; get into, overload or interfere with it or with anybody else’s account; copy, resell or build a competing product from it; or get around any limit of the plan you are on.

What you share with other runners

Jaksa has no tolerance for objectionable content or abusive users. Comments, cheers, photos, names and pictures that other runners see must not be abusive, threatening, hateful, sexual, spam or anybody else’s. Every comment and cheer is checked before others see it, and one that reads as abusive is held back. Anybody can report a comment, a cheer, a photo, a workout or a runner, and block a runner, from the app or jaksa.run; a person at Jaksa looks at every report within 24 hours, removes what breaks these terms and closes the accounts of those who post it. You can also write to hello@jaksa.run.

Price and payment

Jaksa costs nothing today. We may start charging for it, or for parts of it, at any time, and set and change prices as we choose. You pay the price you agreed to when you bought — shown to you before you pay. A new price applies from your next purchase or renewal, and you can cancel before it does.

Bought inside the iPhone app, Apple bills you: Apple takes the payment, its terms govern the purchase, and refunds and cancellations go through your Apple account. Bought on jaksa.run, the seller is us. A subscription renews until you cancel it and ends at the end of the period you paid for. Except where the law gives you a refund, payments are not refunded. We may give anyone free access, or a feature for free, and take it away again at any time.

We may change anything, at any time

Jaksa is offered as it is, and as it happens to be available. We may change, add, remove, pause or stop any part of it — the coach, its voice, the features, the free and paid plans, the outside services it uses — at any time, with or without notice. We may stop Jaksa altogether.

We may change these terms at any time. The new terms apply from the date at the top of this page; if you keep using Jaksa after that, you accept them. If you do not, stop using Jaksa and ask us to delete your account.

Ending your account

We may suspend or close any account at any time, for any reason or none, with or without notice. You may stop at any time and ask us to delete your account, as the privacy page explains. Deleting your account does not cancel a subscription bought from Apple — cancel that in your Apple account. If we close your account for no fault of yours while you have a paid period left, we refund the part not used (for a purchase from Apple, we support your refund request to Apple). When an account is closed, its data is deleted as the privacy page says.

No promises

To the fullest extent the law allows, Jaksa is provided “as is” and “as available”, without any promise or warranty, express or implied — including that it is accurate, safe, fit for any purpose, always working, free of errors, or that it will keep your data forever. A workout may not be recorded, sent, saved to Apple Health or uploaded to Strava.

Our liability

To the fullest extent the law allows, we are not liable for any injury, illness, loss or damage that comes from running, from following or ignoring the coach, or from wrong or missing numbers; nor for any indirect, incidental, special or consequential loss, lost profit, or lost data. Our total liability for anything to do with Jaksa is limited to the greater of what you paid us for Jaksa in the twelve months before the claim, and US$10.

You will hold us harmless from claims by other people that arise from how you used Jaksa or from breaking these terms.

Nothing here limits liability that the law does not allow to be limited — such as for death or personal injury caused by our negligence where that cannot be excluded, or for fraud — and nothing here takes away rights you have as a consumer that cannot be waived. Where you live in the European Union or the United Kingdom, you also keep your statutory rights to a service that matches its description, and your right to withdraw from a purchase within 14 days where it applies.

Disputes

These terms are governed by the laws of the State of Texas, United States, without regard to their conflict-of-law rules, and disputes go to the state or federal courts in Travis County, Texas. Where you are a consumer, you keep the protection of the mandatory law of the country you live in and may go to its courts. Please write to hello@jaksa.run first; most things are settled there.

The App Store

If you got Jaksa from Apple’s App Store or TestFlight: these terms are between you and us, not Apple. Apple is not responsible for Jaksa or its content, has no duty to maintain or support it, and is not responsible for any claim about it — including product liability, failure to meet a legal or regulatory requirement, consumer protection or privacy law, or a third party’s claim that Jaksa infringes their intellectual property. If Jaksa fails to meet a warranty that applies to it, you may tell Apple, which will refund the price you paid for the app, if any; beyond that Apple has no warranty obligation. You confirm you are not in a country under a US government embargo and not on a US government list of prohibited or restricted parties. Apple’s own licence for apps from the App Store also applies to you. Apple and its subsidiaries may enforce this paragraph against you.

The rest

If a part of these terms cannot be enforced, the rest still applies, and that part applies as far as the law allows. These terms and the privacy page are the whole agreement about Jaksa. If we do not enforce something at once, we have not given it up. We may transfer this agreement to anyone who takes over Jaksa; you may not transfer it.
