Terms of use

These are the rules for using Aste. You accept them when you create an account, and again each time you sign in.

Last updated 27 September 2026

In these terms, Aste means the app and the service behind it, and you means the person using it.

When you create an account you tick a box that accepts these terms, and the log-in screen says that continuing means accepting them. Both link here. If you do not accept them, do not create an account or log in. The box at sign-up also records your consent to Aste holding your health data. That consent is a separate matter from these terms, set out in the privacy policy, and you can withdraw it without ending this agreement.

What Aste is

Aste builds a running training plan for a race you name and adjusts it as your training develops. It sets runs with target distances, target paces and heart-rate ranges, complementary strength sessions, and a daily calorie target with protein, carbs and fat to support them. You record runs in the app or on your watch and log meals by photo or by hand, and the plan reads what you actually did.

The plan is produced by a fixed calculation. The same inputs give the same plan. What changes is your training: miss sessions, or run faster or slower than target, and the calculation runs again on the newer numbers. The numbers you give it are what it works from, so a number that is wrong or out of date produces a plan that is wrong with it.

The coach's written notes work differently. The briefings, debriefs and meal notes are written by a language model from a small set of numbers about your training. That text can be wrong. The numbers on the screen are the plan, and if a note reads differently from them, the numbers win.

Aste is a training app, not medical care

Aste asks what your body is like and what you have been running: your height, weight, age and sex, how far you run and how fast. It uses those answers to decide how far and how fast to start you and how quickly to build. That is a training model applied to the numbers you gave it.

It is not a medical assessment. Nobody examines you. Aste does not diagnose anything, does not treat anything, and does not supervise your training. It does not ask whether you are injured, and the plan does not take an injury into account.

Aste does not replace a doctor, a physiotherapist or a dietitian. Talk to one before you start if you have a heart, lung or metabolic condition, if you are pregnant, if you are recovering from injury, illness or surgery, if you have been told to follow a prescribed diet, if you have or have had an eating disorder or any other reason a calorie or macronutrient target could do you harm, or if it has been a long time since you trained. Keep talking to them while you train. If a clinician tells you something different from what the plan says, follow the clinician.

The calorie and macronutrient numbers in Aste are estimates for a healthy adult in training. Do not use them to manage a medical condition, or anywhere precise nutrition matters medically.

Who can use it

You need to be 18 or older. Aste sets calorie targets and training loads, and those are not for anyone still growing. If you are under 18, do not create an account. An account found to belong to someone under 18 is closed and its data deleted.

You also need to be able to enter into a binding agreement where you live, and to use Aste only where it is legal to do so.

Your account

An account belongs to one person. Your plan is built from your numbers, so a shared account produces a plan that fits nobody using it.

You sign in with an email address and password, with Apple, or with Google. Keep your sign-in details to yourself. You are responsible for what you do under your account. You are not responsible for someone getting in through a failure on Aste's side, and nothing in these terms moves that onto you. If you think someone else has got into your account, change your password or revoke Aste's access with Apple or Google, then write to support@asteperformance.com.

What you put into Aste

The runs, meals, photos, notes and plan settings you enter stay yours. Creating an account does not hand any of it over to Alexhander Törnqvist.

Aste needs permission to handle that content in order to run the service for you, and it takes no more than that. The permission covers storing your content, showing it back to you, processing it to build and adapt your plan, keeping the service secure, and meeting a legal duty. It covers sending a meal photo to the model that estimates what is on the plate, and sending a small set of numbers about your training to the model that writes the coach's notes. The privacy policy sets out what is sent and to whom.

Aste does not publish your content, does not sell it, does not show it to other users, and does not use it to train models. The permission lasts as long as the content is in your account. Delete the account and the permission ends with it.

What you put in has to be yours to put in. Do not upload photos of other people who have not agreed to it, and do not upload anything unlawful.

What stays Aste's

The app itself, its design, its training calculation, its text and its name belong to Alexhander Törnqvist. While you have an account you can use Aste for your own training, and that is the whole of the licence: it does not let you copy the app, sell access to it, or use it to run a coaching business. Whatever the law lets you do regardless of this document, you can still do.

Watches, Apple Health and other services

Parts of Aste depend on things that are not Aste: Apple Health, Apple Watch, GPS, Apple Maps, Sign in with Apple and Google sign-in. Each has its own terms and its own privacy rules. You choose which permissions to grant, and a feature that genuinely needs one will not work without it. A measurement from a watch, a phone sensor or another app can be incomplete or wrong, and Aste cannot vouch for it. The privacy policy sets out what Aste reads from, writes to and sends through each of these.

Paying for Aste

This section describes how paying for Aste will work once it starts. It applies from the point that billing is switched on, and you will be told before anything is charged.

Paid subscriptions will be sold as in-app purchases through the App Store. Apple takes the payment under Apple's own terms, and the App Store shows the price, the billing period and the renewal date before you confirm.

A subscription renews until you cancel it. You cancel in your Apple account settings rather than in Aste. A free trial becomes a paid subscription when the trial ends unless you cancel before then, and before a trial starts you will be shown how long it lasts, what it becomes, and how to stop it.

Prices can change. A change applies from the next billing period, and Apple tells you about it before it takes effect. Where the law requires your agreement to a new price, the new price does not apply until you have given it.

Deleting Aste, or deleting your Aste account, does not cancel a subscription. Cancel it with Apple separately, or it keeps renewing.

Refunds, and changing your mind

Apple takes the payment, so money comes back through Apple: ask through the App Store. Alexhander Törnqvist cannot charge, cancel or refund an App Store purchase for you directly. That is the mechanism, not the limit of your rights. If Aste does not work the way consumer law says a digital service must, your claim is against Aste, and you make it by writing to support@asteperformance.com. A refund that Aste owes you is arranged through Apple's systems.

Consumer law in Sweden and the rest of the EU gives you 14 days to withdraw from a subscription bought at a distance. Before billing starts, this section will say exactly where that is done, whether through the App Store or a function Aste provides, and you will get an acknowledgement recording when your withdrawal arrived. A clear statement to the address above counts from the day it is sent. If you asked for the service to start inside those 14 days, the law decides whether a share of the price is owed for the part you used.

Apple's part in this

Aste is distributed through the App Store, and when you download it Apple's terms apply to that download. Apple is not a party to this agreement and is not responsible for Aste or for supporting it. Apple's only obligation to you if the app does not work is the refund its own terms provide for; your rights against Aste are set out above and are not reduced by this. Apple may enforce these terms against you as a third party.

Using Aste fairly

• Use Aste for your own training. Do not use it to coach or track someone else, and do not use it to run a coaching service for others.
• Do not sell, rent or share access to your account, and do not use anyone else's.
• Do not attack the service, overload it, or look for ways into other people's data.
• Do not copy the app, take it apart, or automate your way around it, beyond whatever the law allows you to do regardless of what this document says.
• Do not upload anything unlawful.

Suspending or closing an account

An account can be restricted, suspended or closed for a serious or repeated breach of these rules, for unlawful use, for fraud, for a real security risk, for misuse of someone else's account or information, or because the law requires it. Where it is reasonable to say what is wrong and give you a chance to put it right first, that is what happens. Where security, safety, fraud or the law make waiting unreasonable, the account is closed at once.

A closed paid account keeps whatever refund or remedy consumer law gives it. Where it is possible and lawful, you can get a copy of your data before the account goes.

Testing, changes and stopping

Aste is in testing. Screens change and features arrive and disappear. The engine behind the plan is still being corrected. The service can be unavailable, and there is no uptime commitment.

Aste changes when there is a reason to: to improve or develop it, to fix an error, to keep it secure, to keep up with iOS, Apple Health or another service it depends on, to prevent abuse, to meet the law, or to retire something that can no longer be maintained. A change never costs you more inside a period you have already paid for. Where consumer law requires notice of a change to a service you are paying for, you get it by email. If a change makes the service materially worse for you, the right the law gives you to end the subscription because of it is yours to use.

You can stop at any time. Delete your account from Security & privacy in your profile. Deletion runs immediately and it is permanent: your account and everything stored against it go, with no grace period and nothing to undo. The privacy policy sets out exactly what is removed and when, and what can linger briefly in a backup. If you want a copy of anything, ask at support@asteperformance.com before you delete. Deleting your account does not cancel an App Store subscription.

If Aste is discontinued, you will be told by email, with enough notice to get a copy of your data out. Any refund or other remedy consumer law gives you for a period you have paid for and can no longer use stays yours. Where the money has to come back through Apple, you will be told how.

What you can hold Aste to

Aste does not promise results. The plan is a calculation from the numbers it has. It does not promise you a race time, a finishing position, a change in your body, or that you will not get injured. Nutrition targets are estimates, a meal read from a photo is an approximation of what was on the plate, and the coach's written notes can be wrong.

Those are the limits of what a training app can promise. They do not remove the duty to provide a service that works the way consumer law says a digital service must, and they do not change your rights when it does not.

Alexhander Törnqvist is not liable for loss that could not reasonably have been foreseen when you started using Aste, for training decisions you take against medical advice or against a clear warning from your body or from the app, for the consequences of numbers you knowingly entered wrongly, or for data that is gone because you deleted your account. None of that applies where the law makes Aste liable regardless.

Some liability cannot be limited and this document does not try to. Nothing here limits liability for death or personal injury caused by negligence, for fraud, for wilful misconduct, or for anything else that mandatory law does not allow to be excluded.

If you are a consumer, your statutory rights survive these terms. The mandatory consumer law of the country you live in applies whatever this document says, and nothing here removes those rights or cuts them down.

Which law applies

Swedish law governs these terms.

That does not take away the protection you have as a consumer at home. If you live in another country in the EU or the EEA, the mandatory consumer law of that country still applies to you, you can bring proceedings in the courts where you live, and any proceedings against you will be brought there. Outside the EU and the EEA, the consumer rules of your own country decide which courts are open to you.

If something goes wrong, write to support@asteperformance.com first; most things can be settled directly. If it cannot be, a consumer can take it to an out-of-court dispute body. In Sweden that is the National Board for Consumer Disputes (Allmänna reklamationsnämnden, ARN, Box 174, 101 23 Stockholm, arn.se). Aste takes part in an ARN case brought against it and follows ARN's recommendation. Elsewhere in the EU and the EEA it is the equivalent body where you live.

Changes to these terms

These terms change when there is a reason to change them: the app changes, the law changes, the way Aste is paid for changes, a feature is added, or wording needs correcting. The date at the top says when they last did.

You will be told by email before a change that materially affects you takes effect. A change never takes away a right you already have. Where the law needs your agreement to a change, the change does not bind you until you have given it. If you do not accept a change, stop using Aste and delete your account; any right consumer law gives you to end a paid subscription because of the change stays yours.

Reaching a person

Write to support@asteperformance.com. It is the address for anything about these terms, your account, a complaint, or something the app did that you do not understand.
