1. Who we are
Duōdeka is an app published by Nathan Dolard Villard, sole trader (entrepreneur individuel), 34 grande rue de Laborde, 21200 Montagny-lès-Beaune, France, SIRET 93128082000016, reachable at hello@duodeka.app (“we”). The full legal notice is in Profile › About.
2. Acceptance
By creating an account, you accept these terms. If you do not agree, do not use the app.
They add to the terms of the App Store or Google Play, where you downloaded the app. For anything related to payment, the store’s terms apply.
3. The service
Duōdeka is a habit game for two. You form a duo with another person, you prepare a season (14 to 92 days) with your habits and wishes, then each of you checks off habits day after day to earn XP. At the end of the season, whoever is ahead wins and may receive a gift chosen from their wishes.
Duōdeka is a game. It is not a health service, nor medical, fitness or nutrition coaching. Choose habits that suit your health and, if in doubt, ask a professional.
4. Your account
You must be at least 15 years old to create an account.
You sign in with an email address and password, with Apple or with Google. You agree to provide accurate information, to have only one account and to keep your access secret: anything done from your account is deemed done by you. If you think someone accessed it, change your password and write to us.
5. The duo
A duo brings two accounts together. You invite your partner with a code or a QR code, and the duo is formed when they accept.
Either of you can leave the duo at any time. The current season then ends without a winner; XP already earned stays in each person’s history.
Only form a duo with someone who wants to, and do not use Duōdeka to monitor, control or pressure anyone.
6. Game rules and points
Checking off a habit is self-reported: the game relies on everyone’s honesty, and we do not verify that the habit was actually done.
XP, streaks, jokers, medals and results have no monetary value. They cannot be traded, sold or converted into money or Pro.
We may adjust the rules and balance to improve the game, taking care not to upset a season in progress, except to fix an error or fraud.
7. Wishes and gifts
Wishes are gift ideas that each player adds to the season. Giving the gift is a commitment between you and your partner: we sell nothing, collect nothing, deliver nothing and do not guarantee that the gift will be given.
Links and prices are entered by players; the websites they lead to are not under our control. Do not put anything illegal, dangerous or degrading in your wishes.
8. Your content
You keep ownership of what you write: nickname, habits, wishes, feedback. You only allow us to store it, show it to you and your partner and process it to run the app, for as long as your account exists.
You agree not to write anything unlawful, hateful, harassing, violent or sexual involving minors, or anything that infringes other people’s rights (privacy, image, copyright, trademarks).
Your content is only visible to your duo. We do not review it in advance, but we may remove content that is reported or manifestly unlawful.
9. Reporting content
To report unlawful content or behaviour, write to support@duodeka.app explaining what it is, where it is and why you think it is unlawful. We reply promptly. Any removal or suspension decision is explained, and can be challenged at the same address.
10. What is not allowed
- Getting around the limits of the free plan or the payment for Pro.
- Creating fake or multiple accounts, in particular to benefit from referrals.
- Accessing or trying to access other people’s data.
- Automating use of the app, overloading it or disrupting it.
- Decompiling or copying the app, except where the law allows it.
- Impersonating someone else.
11. Free plan and Duōdeka Pro
Duōdeka is free, with limits: 4 habits in play, 1 reminder per habit and no widgets. Duōdeka Pro removes these limits: unlimited habits, up to 3 reminders per habit and all widgets. The Pro features that apply are those shown in the app at the time of purchase.
A single purchase activates Pro for you and your partner, for as long as your duo exists. If the duo splits up, Pro stays with the person who bought it and the other person loses it; it is then shared with the buyer’s next partner.
12. Prices and plans
Pro is available as a monthly subscription, a yearly subscription or a one-time “lifetime” purchase. Prices in France, all taxes included: €1.99 per month, €11.99 per year, €29.99 lifetime.
The price that applies is the one shown by the store at the time of purchase: it may vary by country, currency and local taxes. There is no free trial, apart from referral benefits (section 17). Offers limited in time or in number of seats may be available; their conditions are shown with them.
13. Ordering and payment
You buy in the app, through the App Store or Google Play, with the payment method of your store account. The store collects the payment and sends you the confirmation; we never see your bank details.
Pro is activated as soon as the store confirms the purchase, for you and your duo. On a new device, you get your purchase back with “Restore purchases”, using the same store account.
14. Renewal and cancellation
Monthly and yearly subscriptions renew automatically for the same period until you stop them. To stop, go to your store’s subscription settings at least 24 hours before the renewal date. Pro stays active until the end of the paid period; a period already started is not refunded pro rata.
Deleting the app or your Duōdeka account does not stop the subscription: remember to cancel it in your store.
If a subscription price goes up, the store notifies you beforehand and, under its rules, asks for your consent. If a payment fails, the store may grant a grace period during which Pro stays active.
15. Lifetime purchase
The “lifetime” purchase is paid once and does not renew. It gives access to Pro for as long as Duōdeka is operated, not for the buyer’s lifetime. If we were to shut the app down, we would notify you at least 3 months in advance (section 22).
16. Withdrawal and refunds
Purchases are made through the App Store or Google Play, which handle the right of withdrawal and refunds under their own terms. Any refund request is therefore made to the store.
Pro is digital content supplied immediately. Where the law allows it (article L221-28, 13° of the French Consumer Code), by requesting immediate activation of Pro when you buy, you agree that performance starts before the end of the 14-day withdrawal period and you waive that right.
17. Referrals
Once formed, a duo gets a referral code shared by both members, to share with people outside the duo.
A referred person “qualifies” once they have entered the code within 7 days of signing up, confirmed their email address and checked off at least one habit on 3 different game days. For every 2 qualified people, the duo earns 1 month of Pro, which either member activates, up to 3 months (6 people).
The referred person gets 14 days of Pro, starting when their own duo is formed, once per duo.
If the referring duo splits up, its code is disabled and months not yet activated are lost. Referral benefits have no monetary value and are neither transferable nor refundable. We may cancel benefits obtained through fraud, such as fake accounts.
18. Legal guarantee of conformity
You benefit from the legal guarantee of conformity for digital content and services (articles L224-25-12 and following of the French Consumer Code). If Pro does not conform, you can have it brought into conformity or, failing that, obtain a price reduction or end the contract.
For a subscription, the guarantee covers the whole supply period. For the lifetime purchase, it covers defects that appear within 2 years of purchase. We provide the updates needed to keep Pro in conformity. To use the guarantee, write to support@duodeka.app.
19. Availability and changes
We do our best to keep Duōdeka running without interruption, but cannot guarantee it: maintenance or an outage of the host, the network or the stores may interrupt it.
The app evolves: features may appear, change or disappear. If we remove or reduce a Pro feature, you are told in advance and, if this affects you negatively, you can cancel your subscription.
20. Liability
We are liable for direct damage caused by a breach of our obligations, under the conditions set by law.
We are not liable for how you practise your habits (sport, diet, sleep…), for your relationship with your partner or gifts between you, for content written by players, or for an interruption caused by a third party or by force majeure.
Nothing in these terms limits the rights the law guarantees you as a consumer.
21. Intellectual property and licence
The app, its name, its hydras and illustrations, its texts, animations and code belong to us or are used with permission.
We grant you a personal, non-exclusive, non-transferable and revocable licence to use Duōdeka for private purposes, on devices you own or control, in line with your store’s rules (including family sharing where the store allows it).
22. Suspension and termination
You can delete your account at any time from Profile › Account; deletion is permanent.
We may suspend or close an account for a serious or repeated breach of these terms, after warning you and letting you explain, except in urgent cases (fraud, security, manifestly unlawful content). Closure for a breach does not entitle you to a refund of Pro, unless the law provides otherwise.
If we shut Duōdeka down, we notify you at least 3 months in advance, and subscriptions are no longer renewed.
23. If you use the App Store
If you downloaded Duōdeka from the App Store:
- these terms are between you and us, not Apple; we alone are responsible for the app and its content;
- Apple has no obligation to provide maintenance or support for the app;
- if the app fails to conform, you may notify Apple, which may refund its purchase price; to the extent permitted by law, Apple has no other warranty obligation;
- Apple is not responsible for addressing claims relating to the app (product liability, legal or regulatory compliance, consumer protection, intellectual property): we are;
- you represent that you are not located in a country subject to a US embargo and are not on any US government list of prohibited or restricted parties;
- Apple and its subsidiaries are third-party beneficiaries of these terms and may enforce them.
24. Changes to these terms
We may change these terms, for example when the app or the law changes. For any significant change, you are notified in the app at least 30 days in advance. If you refuse, you can delete your account and cancel your subscription; if you keep using Duōdeka after that date, you accept the new terms.
25. Complaints and mediation
If something goes wrong, write to support@duodeka.app first: we will look for an amicable solution.
If your written complaint is not resolved, you can refer the matter free of charge to our consumer mediator: Société Médiation Professionnelle, Médiation de la consommation, Alteritae 5, rue Salvaing, 12000 Rodez, https://www.mediateur-consommation-smp.fr/.
26. Governing law
These terms are governed by French law. If you live in another European Union country, you keep the protection of the mandatory rules of your country. In case of dispute, you can go to the court where you live or any other court with jurisdiction under the law.
If a clause were held invalid, the others would continue to apply.
