Terms of Use

Version of 25 September 2026 · Scope: milewise.de, app.milewise.de, the Milewise apps for iOS and Android, and the related electronic communication · Deutsche Fassung (verbindlich)

1. The agreement, and who you contract with

These terms are issued by:

Phone: +49 721 18126138 · Email: contact@milewise.de · VAT identification number: DE464647453 · no commercial register entry · legal notice.

There are two separate contracts.

• The service contract with us. It comes into existence when you create an account and covers the account, the coach and the data connections. It applies to a free account too: because you provide us with personal data for it, it is a consumer distance contract under section 312(1a) of the German Civil Code (BGB), with everything that follows from that, including a right of withdrawal.
• The purchase contract for the subscription. Who your counterparty is depends on where you buy.
  On the web at app.milewise.de: you buy the subscription from us. The payment runs through Stripe Managed Payments, in which “Sold through Link, LLC” (United States) acts as the merchant of record on our behalf. That is the name shown to you at checkout, on the receipt and on the invoice; the invoice carries that company's name and tax details rather than ours, and Stripe collects and remits the VAT. Merchant of record is a payment and tax role: the seller of the service remains us, and none of our consumer-law duties towards you move with it. You cancel with us (section 10) and you withdraw towards us (section 11). In addition you can ask Link support to cancel or to refund, and Stripe can refund a payment itself within 60 days, including without our agreement if we do not answer within 48 hours.
  In the iOS app: Apple sells the subscription under the Paid Applications Agreement we signed, in one of two roles depending on the region you buy from. In the European Union and most other regions Apple is our commissionaire: Apple Distribution International Ltd., Hollyhill Industrial Estate, Hollyhill, Cork, Ireland (in some regions of Asia and the Pacific, Apple Services Pte. Ltd.), concludes the purchase in its own name on our behalf, so the purchase contract is with Apple and the contract for using Milewise is with us. In the United States, Canada, Australia, New Zealand, Japan, Latin America and the Caribbean Apple is our agent (Apple Inc., Apple Canada Inc., Apple Pty Limited, iTunes KK or Apple Services LATAM LLC): it concludes the purchase in our name, so the purchase contract is with us, made through Apple.
  In the Android app: the content is offered by Google Commerce Limited, 70 Sir John Rogerson’s Quay, Dublin 2, D02 R296, Ireland, and Google Play is provided by Google Ireland Limited.
  For a purchase in either store their terms govern it: you buy there, you cancel there, you withdraw there, and they decide and pay any refund. For Google Play, Google’s own refund page asks you to come to us first when there is a problem with a purchase. We supply the service itself, and these terms govern that without change.

The contract languages are German and English. The German version is the binding one; this English text is a non-binding courtesy translation. How we process personal data is described in the privacy policy.

2. What Milewise is, and is not

Milewise reads training and wellness data from accounts you connect yourself (intervals.icu, Strava, Polar, Suunto), from files you upload, from recordings made in the app, and, if you give separate consent, from your phone's health store (Apple Health, Health Connect). Out of that it produces a training plan, daily assessments, post-workout reviews and a chat with an AI coach.

3. Who may use it

Minimum age 18. When you create an account we ask for your date of birth. We do not check that answer against a document or a third party. If the age given is under 18, the account is locked: only signing out and deleting remain reachable. A locked account is not deleted automatically; you delete it, or we do on request.

You must have full legal capacity and use Milewise as a consumer, for your own purposes.

United Kingdom. We do not offer Milewise there. When an account is created and when an order is placed on the web, we map the network address the request comes from against a locally held table and refuse if it points to the United Kingdom. That is an effort, not enforcement: addresses can be attributed wrongly, a VPN defeats the check, and the check does not run at sign-in, when browsing this website, or on the purchase route through the App Store or Google Play. We block no Member State of the European Union (Regulation (EU) 2018/302).

The age lock at the top of this section is an automated decision (section 7). You can ask a person to look at it. Write to contact@milewise.de saying that the date of birth was entered wrongly. The operator checks it personally, you can put your side of it, and you can contest the result. Until that is settled the account stays locked rather than being deleted.

4. Your account

Sign-in runs through Google, Apple or Strava. Keep the account you sign in with secure.

An account belongs to one person and is not transferable. So that we can deliver your order confirmation, cancellation and withdrawal acknowledgements and your data export, you need a confirmed email address in the account. Without one, some of those confirmations cannot be delivered.

5. Acceptable use

You must not:

• use another person's account or data, or hold yourself out as someone else;
• circumvent security measures, usage limits, the age gate, the country check or the paywall;
• read the service out automatically, or call it at a volume that impairs operation;
• resell or rent Milewise or make it available to third parties;
• submit unlawful content, or use the coach to produce it.

For a serious breach we may terminate under section 15.

6. Your data and your connected accounts

You set up and disconnect connections to other services yourself. We write only where you have granted that service a write permission. These are all the outbound writes, with their default setting:

• Planned sessions onto your intervals.icu calendar. On by default from the moment you connect, provided you granted intervals.icu calendar write permission and your plan includes a training plan. It can be switched off; if you switch it off, we remove the entries we placed.
• Heart-rate zones and FTP onto your intervals.icu sport settings, on the regular sync. On by default. This overwrites your zone configuration there.
• Planned sessions as a SuuntoPlus guide in your Suunto account. On by default, provided a Suunto account is connected and your plan includes a training plan.
• An identifier registered with Polar. When you connect, we register the identifier milewise-<your account number> with Polar; when you disconnect, we delete it.
• Copying a completed activity to another platform, and renaming it from the plan. Both are off by default and are switched on per service. For Strava, additionally only where you have granted us Strava write permission.
• Carrying your own title and sport outward. When you switch on copying for a service, this travels with it unless you turn it off, and it goes to every connected copy including the platform the workout came from. There is a separate switch for it per service, and one for the account as a whole.
• Deleting at intervals.icu. If you delete an activity with us and choose to propagate, we delete it at intervals.icu too. We also remove copies there that we uploaded ourselves once your own sync delivers the same session.

Nothing reaches your watch on its own. Whether and when that lands on the watch is decided by that platform's own app; that step is yours, not ours.

A workout recorded by Strava is never copied to another platform. That is fixed in the software and is not a setting anyone can flip.

7. The coach, and its limits

The coach is an AI system. Plans, daily briefs, reviews and chat replies are produced by a language model. No human checks them beforehand.

Output can be incomplete or wrong. You decide whether to do, change or skip a session.

The plan, the brief and the review are recommendations with no legal effect and no similarly significant effect; they are not an automated decision within the meaning of Art. 22 GDPR. The age gate in section 3, by contrast, is an automated decision, and its consequence is that the account is locked.

Values such as “stress” come from the service you connected and from its watch manufacturer. We do not compute them and we pass them on under that provider's name.

8. Free scope and subscription

Without a subscription you get the dashboard, your activity history, trends, the heatmap, every connection, sleep, HRV and recovery values, and a training plan built by fixed rules without AI: a rolling week from a preset goal or a single-sport race goal, with the season phases and today’s session.

With a subscription the AI coach and its adaptive plan are added: Coach at EUR 9.99 a month, Pro at EUR 19.99 a month. Pro plans four weeks ahead instead of two and has the higher limits under section 9.

Requirements. The personalised plan, writing the plan outward and reading your calendar additionally require a connected data source other than Strava (intervals.icu, Polar, Suunto, your own files, or your phone's health store). The web application runs in a current version of Chrome, Edge, Safari or Firefox. The Android app requires Android 8.0 or later; the iOS app requires the version stated on its App Store page.

9. Usage limits and the agreed metering

At the web order page you separately confirm a deviation from the objective requirements for a digital product (section 327h BGB): the plan is calculated for a fixed number of chat messages a week, which the order page states for the plan you choose, with further short-term, daily and monthly limits. Without that separate confirmation no order is placed there.

Five limits implement it:

• a short-term limit on chat turns within a few minutes;
• a weekly limit on chat turns, rolling over seven days. The chat tells you when you reach it and when it lifts;
• a monthly ceiling on AI processing per account. At an intermediate step the coach continues on a smaller model; at the hard limit the AI features rest until the month turns over, and you get a notice in the app about it;
• a daily limit on automatic post-workout reviews;
• a daily limit on the reviews you start yourself (“Review now”).

The numbers behind these five limits depend on the plan and can change. We will tell you the current values on request at contact@milewise.de.

10. Price, ordering, trial, renewal, cancellation

Price

Coach EUR 9.99 a month, Pro EUR 19.99 a month. That is also the total price per billing period (one month). These are final prices including all taxes; no further costs arise, there is no setup fee and no minimum term. If you buy in an app, the store shows you the price applicable there in your currency.

Trial

The trial runs for 7 days and is available once per person; to that end we keep the connected identifiers in hashed form, so that it survives a second account. Your payment method is stored before it starts. If the trial ends and you have not cancelled, the payment obligation begins. On the web route we remind you one to two days beforehand by email and in the app. For a subscription bought in a store, Apple and Google decide on the trial under their own rules and send their own reminder; we remind you as well, two to three days beforehand, naming the last day to cancel.

How the contract is concluded on the web

1. You choose a plan.
2. You can correct your entries up to the click by going back and changing the selection.
3. With “Order with obligation to pay” (in German “Zahlungspflichtig bestellen”) you make your contractual declaration.
4. We confirm the conclusion of the contract and send you a contract confirmation containing the contract content by email without delay after your order (section 312f BGB).
5. We store which version of these terms you ordered under, but we do not keep the text as a retrievable document in your account. You can save or print this page at any time, and the contract confirmation carries the contract content.

On the web route the payment is processed through Stripe Managed Payments. Your statement shows LINK.COM* followed by the descriptor set on our payment account; some banks display it differently or not at all. We accept payment by card (Visa, Mastercard, American Express, UnionPay), by Apple Pay and through Link, Stripe’s stored-payment service. Access is provided immediately on conclusion of the contract (section 327b(2) BGB).

Renewal and cancellation

The subscription runs for an indefinite period and renews monthly. You can cancel at any time, with effect from the end of the current billing month. There is no minimum term and no notice period longer than one month. Text form is enough; we require no particular form.

For a subscription bought from us you reach the cancellation without signing in at milewise.de/cancel. That page is the confirmation page, with the button “Jetzt kündigen” (cancel now) on it. You then immediately receive a confirmation of receipt in text form carrying your declaration, its date and its time, together with one link. The time that governs is the time your declaration reached us. The link opens a page carrying that time and one button, “Confirm my cancellation”; pressing it within 24 hours is what stops the renewal at the payment provider. After 24 hours the link stops working and nothing is cancelled automatically: we look at your declaration by hand and write to the address on your account. A payment collected for a period after the end date of a cancellation you validly declared is refunded. In the signed-in account there is a second, different route: a “Cancel subscription” button next to your subscription, which opens the payment provider’s subscription portal and cancels there.

We cannot end a subscription bought in the App Store or on Google Play. It is cancelled in Apple's or Google's subscription settings.

If a payment for a subscription bought from us fails, access continues for a time while the payment provider retries, and after that the account falls back to the free scope. Your data and your chats stay as they are. For a subscription bought in the App Store or on Google Play the store decides when it lapses, and you can end it in the store at any time; if the tier in Milewise does not follow within a few days, write to us and we will set it by hand.

11. Your right of withdrawal

As a consumer you have a right of withdrawal of 14 days, without giving reasons. The full instructions and the model withdrawal form are in the withdrawal policy.

For a subscription concluded with us, the electronic withdrawal function under section 356a BGB is in the signed-in account area at app.milewise.de/you?tab=settings, at the bottom of that page, and works in two steps: first “Vertrag widerrufen” (withdraw from contract), then “Widerruf bestätigen” (confirm withdrawal). After you confirm, we send you an acknowledgement of receipt without delay on a durable medium, containing the content of your declaration and the date and time it was received.

For a free account, where you owe nothing, the right of withdrawal lapses in two steps: the digital content when performance begins (section 356(6) no. 1 BGB), the service only on its complete performance (section 356(5) no. 1 BGB). The withdrawal function under section 356a BGB exists only for a contract with a price; you can still withdraw informally, and you delete a free account under “You”. A subscription bought from Apple or Google is withdrawn from towards Apple or Google, and we offer no function for it.

If you expressly requested that we begin before the withdrawal period expires, you owe us a proportionate amount for the service performed up to the withdrawal, calculated on the agreed total price (section 357a(2) BGB). We will tell you the amount and how it is calculated.

Your right of withdrawal from a subscription does not lapse because you use the coach. A running subscription is not fully performed within 14 days (section 356(5) BGB).

12. Your statutory rights if something is wrong

A statutory warranty right exists for digital content and digital services. We owe you Milewise free of defects in the product and in title for the whole term of the contract (sections 327d, 327e BGB). If the service is defective you can require performance, reduce the price, end the contract and claim damages, in each case under sections 327i et seq. BGB; limitation follows section 327j BGB. We do not restrict these rights and we shorten no period.

Report a defect or a complaint to contact@milewise.de. We answer in text form.

13. Updates, and how long we supply them

We supply the updates needed to keep the service in conformity with the contract, including security updates, and we inform you about them (section 327f BGB).

Minimum period for which software updates are supplied: for as long as your subscription runs, and at least 24 months from purchase.

Please install the app updates we make available. If you do not do so within a reasonable time, we are not liable for a defect that arises solely from that omission (section 327f(2) BGB).

14. Availability, and changes to the service

We promise no particular availability figure. If intervals.icu, Strava, Polar, Suunto, Apple, Google or an AI model provider changes or discontinues an interface, a feature that relies on it can fall away.

We may change Milewise beyond what is needed to maintain conformity with the contract only where there is a valid reason. The valid reasons are exhaustively: the security of the service or of your data; a legal or regulatory requirement; the change or removal of a connected service's interface; the withdrawal or replacement of an AI model; and a technical necessity of operating the service. No additional cost arises for you from such a change.

If such a change impairs your access or the usability of the service more than insignificantly, we will inform you beforehand, within a reasonable period and on a durable medium, of the features and timing of the change and of your right to end the contract free of charge within 30 days (section 327r BGB).

15. Ending the contract

You. You cancel the subscription under section 10. You can delete the account at any time inside the account, or, if you can no longer sign in, by email to contact@milewise.de; we handle that route by hand and in any event within one month (milewise.de/delete-account). Deletion ends a subscription bought from us immediately. A subscription bought in a store keeps running and keeps being charged until you cancel it there, so cancel it before you delete.

Us. We may terminate the free service contract on one month's notice. We may terminate without notice for good cause, in particular for a serious breach of section 5 or if we discontinue the service; we will announce that beforehand where that is possible. If you withdraw a data-protection consent or object to further processing and continuing the contract is therefore unreasonable for us, we may terminate without notice under section 327q(2) BGB. We have no claim against you for compensation because of that (section 327q(3) BGB).

After it ends. You may not continue to use Milewise. At your request we will provide you, free of charge, within a reasonable period and in a common, machine-readable format, with the content you provided or created while using the service that is not personal data (section 327p(3) BGB); the data export in the account delivers the same package. When an account is deleted we remove the calendar entries and Suunto guides we placed and revoke our access where the service in question offers a way to do so. intervals.icu offers no such interface, so you withdraw the access there yourself.

16. Liability

We are liable without limitation for intent and gross negligence, for damage arising from injury to life, body or health, under the German Product Liability Act, and under any guarantee we have given.

For ordinary negligence we are liable only for breach of a material contractual duty, that is a duty whose performance makes the proper performance of the contract possible in the first place and on whose observance you regularly rely, and then limited in amount to the foreseeable damage typical for this contract.

Beyond that our liability is excluded. The same applies to our legal representatives and to the people we use to perform the contract. None of this changes the burden of proof to your disadvantage.

You decide on every training session yourself; section 2 applies.

17. Changes to these terms

We change these terms only where the law or the case law changes, where an authority or a court requires it, or where we introduce or change a feature for which these terms contain no provision.

We will inform you at least 30 days beforehand, in text form, of the change and the date from which it is to apply, and we will ask for your agreement. Silence does not count as agreement. If you do not agree, the previous terms continue to apply to you; we may then terminate the contract in the ordinary way under section 15. Changes to the service itself are governed by section 14.

18. Final provisions

German law applies. The mandatory consumer-protection provisions of the country in which you have your habitual residence continue to apply (Art. 6(2) of the Rome I Regulation). We agree no exclusive place of jurisdiction with you as a consumer.

Consumer dispute resolution. We are not obliged to give the information under section 36(1) no. 1 of the German Consumer Dispute Resolution Act (VSBG) (section 36(3) VSBG). We are not willing to take part in dispute resolution proceedings before a consumer arbitration board.

Transfer. If we hand the contract to another provider, we will tell you beforehand and you may cancel up to the handover.

Attribution. The country mapping in section 3 uses the IP to Country Lite database by db-ip.com under the CC BY 4.0 licence.
