Terms of Service

SweatPotatoes — What we owe each other. The short version: we host a promise, you do the exercise.

Last updated: 22 August 2026 · Effective: 22 August 2026

1. Who you are contracting with

SweatPotatoes is published by Thomas Viot, sole trader (micro-enterprise) trading as Serviprog, registered at 19 chemin des Mûriers, 66680 Canohès, France, registration number 930 679 204, VAT number FR03930679204.

By creating an account or using the app, you accept these terms, in force since 22 August 2026. If you do not accept them, do not use the app. You can reach us at contact@sweatpotatoes.app.

2. What the app is

SweatPotatoes lets two people — a duo — promise each other a session of physical activity, and then hold each other to it. A pact says what you will do, for how long, when and where. Each of you says whether you did it, and, when you did not, writes a line about what happened.

It is a commitment tool. It is deliberately not a fitness tracker, a coach, or a training plan: it measures nothing, grades nothing, and tells you nothing about how you ought to exercise.

3. Who can use it

You must be at least 16 years old and able to enter into a contract. One person, one account. You are responsible for keeping your sign-in details to yourself, and for what happens through your account.

4. Your health, and your risk

We are not medical professionals. Nothing in the app is medical advice, a diagnosis, a treatment, or a training programme written for you — the routines it offers are generic descriptions of ordinary activities, not a plan built for your body.

Before starting or changing an exercise habit, and in particular if you are pregnant, recovering from an injury or an illness, taking medication, or living with a heart, joint or respiratory condition, talk to a doctor.

The app will never tell you that you must go. A pact is a promise between two people, not an instruction from us.

5. The duo

The app works by showing one specific person what you write in it. Before you invite anyone, read section 3 of the privacy policy: it lists exactly what your partner will see, including the note you write when a session did not happen, and any photo you send.

• An invitation is a code, or a link carrying that code, which you send yourself. Anyone holding an unused code can join your duo — send it to the person you meant to send it to.
• You can be in one active duo at a time.
• Either of you can leave, at any time, from Settings. Leaving ends the sharing of everything that comes after it; the pacts you already shared stay in the record.

6. What you write in the app

You keep every right you have over what you write and the photos you send. You give us permission to host, store and display that content for one purpose only: running the app — showing it to you, and to your duo partner. None of it is used for advertising, and we never make it public.

Please do not send, through the app:

• anything illegal, hateful, harassing, threatening or defamatory;
• sexual content or nudity;
• photographs of other people who have not agreed to appear in them;
• other people's personal data;
• anything that infringes someone else's rights.

We can remove content that breaks these rules and suspend the account behind it. A duo is two people who chose each other: if something goes wrong, leaving the duo stops the sharing immediately, and you can report abuse to contact@sweatpotatoes.app.

A routine can also be written by a user and shared with their partner. Its author alone is responsible for it: we neither check nor approve the content of those routines, and they are in no sense sporting advice. Section 4 applies to them in full.

7. Free access, subscription and prices

What is free

Your first complete pact is free: the promise, the hour, the tick, and whatever the two of you get at the end of it. It only starts once a partner has joined you, so an account still waiting for a friend costs nothing and runs out of nothing.

After that, making new promises needs a subscription. Recording a session that already happened, and reading your past pacts, stay open.

The subscription

• Yearly — 49.99 € per year — Renews once a year.
• Monthly — 9.99 € per month — Renews once a month.

The price the store shows you in the app is the one that applies, in your currency and including applicable taxes. Where it differs from the figures above, the store is right.

One subscription covers the duo: while your duo is active, your partner has the same access you do, at no extra cost. The subscription belongs to whoever paid for it — if the duo ends, they keep it and the other person does not.

Free trial, renewal, cancellation

Where a free trial is offered, it starts when you press the subscribe button and turns into a paid subscription automatically unless you cancel at least 24 hours before it ends.

Subscriptions renew automatically at the end of each period unless you cancel at least 24 hours before that period ends. Cancelling happens in your store account — on iOS, Settings, your name, Subscriptions; on Android, the Play Store, Subscriptions — and not in this app: we cannot cancel a store subscription for you. Cancelling stops the next renewal and does not refund the period already paid, which runs to its end.

Payment and refunds

Payment is taken by Apple or Google under their own terms, and we never see your payment details. Refunds are handled by whichever store took the money: contact Apple Support or Google Play Support.

As a consumer in the European Union you have 14 days to withdraw from a contract for a digital service. By subscribing and getting access straight away, you ask us to start performing during that period and accept that the right of withdrawal is lost once the service has been fully performed. In practice, refund requests go through the store.

We may change our prices. A change never applies to a period already paid for, and we will tell you before it applies to a renewal, in time for you to cancel.

8. Availability

We do our best to keep the app running, and we do not promise that it always will: maintenance, an incident, or a failure at one of the providers we depend on can all interrupt it. We may change or remove features; if a change substantially reduces what you paid for, you can cancel and, where the law says so, get the unused part back.

The app needs a network connection, a supported device, and — for notifications and the home screen widget — permissions you grant on your device.

9. Ending it

You can stop using the app whenever you like, and delete your account from inside it. Deleting your account ends these terms. It does not cancel a store subscription, which you cancel in the store.

We can suspend or close an account that breaks these terms, that is used fraudulently, or that puts other people at risk. Where the problem is minor and fixable, we will tell you first.

10. What belongs to whom

The app, its code, its design, its drawings and the name SweatPotatoes are ours. You get a personal, non-transferable licence to use the app on devices you own or control, for your own use. You may not copy it, sell it, rent it, decompile it or extract its content beyond what the law allows whatever a contract says.

11. Liability

Nothing here limits our liability for death or personal injury caused by our negligence, for fraud, or for anything else the law does not let us limit. If you are a consumer, your statutory rights — including the French legal guarantees of conformity and against hidden defects — apply in full.

Subject to that, we are not liable for:

• injury, accident or ill health arising from the physical activity you chose to do (see section 4);
• what your duo partner does, writes, or fails to do;
• loss caused by a notification that arrived late or not at all — the app is a reminder between two people, not a safety system;
• indirect or unforeseeable loss.

Where our liability is engaged and can be limited, it is limited to what you paid us in the 12 months before the event.

12. Changes to these terms

We may update these terms, and we will tell you in the app or by email before a significant change takes effect. Carrying on after that means you accept the new version; if you would rather not, you can delete your account.

13. Law, and disputes

These terms are governed by French law. If you are a consumer living in another EU country, you keep the protection of the mandatory rules of your own country's law.

If something goes wrong, write to contact@sweatpotatoes.app first — most things are settled that way. Failing that, you can use a consumer mediation procedure free of charge, with CM2C, 49 rue de Ponthieu, 75008 Paris, France, litiges@cm2c.net, www.cm2c.net/declarer-un-litige.php. Failing agreement, the dispute goes before the French courts. If you are not a consumer, the courts of Perpignan (66000, France) have sole jurisdiction. If you are a consumer, you may bring the case before the court where you lived when the contract was made or where the damage occurred, or before the courts of Perpignan, where the publisher is based.

Annex — Apple App Store

These terms apply in addition to Apple's own, and the following is required by Apple for apps distributed on the App Store:

• This agreement is between you and us only, not with Apple. We, not Apple, are solely responsible for the app and its content.
• Apple grants you a licence to use the app on any Apple-branded device you own or control, as permitted by the Usage Rules in the Apple Media Services Terms and Conditions.
• Apple has no obligation to provide maintenance or support for the app.
• If the app fails to conform to any applicable warranty, you may notify Apple, and Apple will refund the purchase price. To the maximum extent permitted by law, Apple has no other warranty obligation with respect to the app.
• We, not Apple, are responsible for addressing any claim by you or a third party relating to the app, including product liability claims, any claim that the app fails to meet a legal or regulatory requirement, and claims under consumer protection or similar legislation.
• We, not Apple, are responsible for the investigation, defence, settlement and discharge of any third-party claim that the app infringes intellectual property rights.
• You confirm that you are not located in a country subject to a US Government embargo or designated as a terrorist supporting country, and that you are not on any US Government list of prohibited or restricted parties.
• Apple and its subsidiaries are third-party beneficiaries of these terms and, upon your acceptance, have the right to enforce them against you.
