Duro Terms of Use (End User Licence Agreement)

Version 1.2 — last updated: 23 October 2026

These terms of use (the "Terms") form the agreement between you and ALLURE for the use of the Duro iPhone app. They serve as the end user licence agreement ("EULA") for the App Store. By downloading, using or subscribing to Duro, you accept these Terms. If you do not accept them, do not use Duro.

1. Publisher

Duro is published by ALLURE, a simplified joint-stock company (société par actions simplifiée) with share capital of 1 000 €:

• registered office: 32 rue de Paris, 92100 Boulogne-Billancourt, France;

2. Minimum age: 18

Duro is reserved for adults (aged 18 and over). By using Duro, you declare that you are at least 18 years old. We may delete the data of, and block access for, any minor.

3. What Duro is, and what it is not

Duro is a training and wellness programme: pelvic floor (Kegel) exercises, breathing exercises, progress tracking, reminders, and an artificial intelligence-based coach ("Victor"). Some features are available free of charge (preview mode); the others require a subscription.

Duro is not a medical device. It does not diagnose, treat, cure or prevent any disease, and it does not replace medical advice, a healthcare professional or treatment. The figures and studies cited in the app are general, sourced information (Settings › Health & sources). Results vary from person to person and are not guaranteed.

4. Health warnings

• Consult a doctor before starting if you have a prostate, bladder or pelvic condition, if you have recently had surgery in that area, if you have a urinary or genital infection, diabetes, high blood pressure, a heart or respiratory condition, or if you are undergoing medical treatment.
• Talk to a doctor if you experience pain, blood in your urine or semen, a disorder that appeared suddenly, or persistent erectile dysfunction: it may be a sign of a cardiovascular problem.
• Stop an exercise immediately if you experience pain, dizziness, faintness or unusual breathlessness.
• Breathing exercises: never practise them while driving, in water, or in any situation where light-headedness would be dangerous. Breath-holds should remain comfortable.
• AI coach: Victor is an artificial intelligence. Its answers may be inaccurate or incomplete. It is not a healthcare professional. In an emergency, call 15 or 112.

5. Licence of use

We grant you a personal, non-exclusive, non-transferable and revocable licence to use Duro, for your private and non-commercial use, on Apple devices that you own or control, in accordance with the usage rules set out in Apple's Media Services Terms and Conditions.

In particular, you agree not to:

• copy, modify, decompile, disassemble or attempt to extract the source code of Duro, except where permitted by law;
• circumvent technical measures (subscription, usage limits) or use the app or its server in an automated manner;
• use the coach to obtain illegal, hateful, dangerous or off-topic content, or attempt to divert it from its role;
• resell, rent or share access to Duro.

The coach is limited to 40 messages per day and 1,000 characters per message. These limits may change.

6. Duro Premium subscription

6.1 Plans

Subscriptions are sold by Apple, through App Store in-app purchase, and billed to your Apple ID. The Duro Premium plans are:

The app's subscription screen shows you two of these plans (for example the annual plan and the 7,99 € monthly plan, or the weekly plan and the 9,99 € monthly plan). They are selected at random the first time you open this screen, and then remain the same thereafter. This random selection does not take into account any information about you (neither your answers, nor your device, nor your country); the only exception is that, with a valid creator code, the screen always offers you the annual plan with a 14-day trial. The prices offered may vary depending on ongoing tests; all plans remain visible and manageable in Settings › Subscriptions. A price test never changes the price of a subscription already taken out.

Prices are given for information purposes. The binding price is the one displayed by Apple on the purchase sheet, in the currency of your App Store storefront, at the time of purchase.

6.2 Automatic renewal

• The subscription renews automatically for the same duration, at the price then in force, unless you cancel it at least 24 hours before the end of the current period.
• Your Apple account is charged within the 24 hours preceding the end of the period.
• Payment is taken upon confirmation of purchase or, in the case of a free trial, at the end of the trial.

6.3 Free trial

• The free trial applies only to the annual plan: 7 days, or 14 days with a valid creator code. The monthly and weekly plans do not include one.
• The trial is reserved for new subscribers, once only per Apple ID for the Duro Premium subscription group. The same applies to the welcome offer (section 7): one introductory offer only per Apple ID.
• If you do not cancel at least 24 hours before the end of the trial, the paid subscription starts automatically at the stated price.
• Any unused portion of a trial is forfeited if you take out another subscription during the trial.
• Duro sends you a reminder 2 days before the end of the trial if you have allowed notifications.

6.4 Managing or cancelling

You can manage and cancel your subscription in a few seconds in iOS Settings › [your name] › Subscriptions › Duro, or from within Duro (Me › Status & subscription › Manage my subscription), which opens the same Apple page. Cancellation takes effect at the end of the current period: you keep access until then. Deleting the app or your data does not cancel your subscription.

6.5 Changing plan

You can switch from one Duro Premium plan to another in Settings › Subscriptions, in accordance with Apple's rules:

• to a longer plan (weekly → monthly, monthly → annual): the change takes effect immediately and Apple refunds you pro rata for the unused period;
• to a shorter plan (annual → monthly, monthly → weekly): the change takes effect at the next renewal;
• in other cases, Apple tells you on the confirmation sheet when the change takes effect.

6.6 Refunds and right of withdrawal

Subscriptions are sold by Apple, which applies its own withdrawal and refund terms (Apple's Media Services Terms and Conditions). In the European Union, you may in particular exercise your right of withdrawal with Apple within the period provided for by those terms. Refund requests are made at reportaproblem.apple.com. Duro never asks you to waive this right.

7. One-time welcome offer

If you abandon the Apple purchase sheet without subscribing, Duro may offer you, once only, a welcome offer: the annual subscription at 29,99 € for the first year (paid upfront, at purchase, with no trial), then 49,99 € per year on renewal, unless cancelled. This offer is reserved for people who have never benefited from a Duro introductory offer on their Apple ID. It is displayed only once, without a countdown, and the struck-through price it displays (49,99 €) is the actual price of the annual plan. It then benefits from the annual plan's loyalty pricing (section 8).

8. Loyalty pricing

The longer your subscription lasts without interruption, the lower its price. These discounts are promotional offers within the meaning of the App Store, reserved for current subscribers, which we offer you when you meet the conditions.

8.1 The tiers

Monthly subscriptions (Bronze status for the first 3 months, at your plan's starting price):

Annual subscription (starting price: 49,99 €/year; same tiers with the 14-day trial or the welcome offer):

Weekly subscription (3,99 €/week): no loyalty pricing. However, weeks paid without interruption count towards your seniority if you subsequently switch to the monthly plan.

Prices are given for France. Apple displays the equivalent price in your currency.

8.2 Activation

• The offer must be activated in the app ("Activate" button, then confirmation on Apple's purchase sheet). It is never applied without action on your part.
• It starts at your next renewal and lasts for the number of periods indicated. Only one offer can be active at a time.
• At the end of the offer, the subscription reverts to the starting price, unless you activate the offer for the next status. Duro notifies you 7 days and 2 days before renewal if your benefit has not been activated.

8.3 Any interruption resets your seniority to zero

Your seniority only counts periods paid without interruption. It resets to zero if your subscription stops, in particular:

• upon expiry, for example after a cancellation that has reached its end date, a payment failure not resolved within the grace period granted by Apple, or a refusal of a price increase;
• in the event of a refund or revocation of your subscription.

The following do not interrupt it: a grace period followed by a successful payment, switching from monthly to annual (or vice versa), and a cancellation withdrawn before it takes effect.

If you return after an interruption, you pay the starting price of the chosen plan again (for example 7,99 €/month or 49,99 €/year), with no trial and no welcome offer, and you work your way back up the statuses from Bronze.

8.4 Changes to the programme

We may change the loyalty programme for the future (tiers, prices, durations), informing you in the app. An offer already activated remains valid until its end. As long as you meet its conditions, the offer for your status remains available in the app; a renewal that occurs before its activation is billed at the price in force at that time.

9. Creator codes

Duro is recommended by partner content creators, who are paid a commission on the subscriptions they bring in. In accordance with Law No. 2023-451 of 9 June 2023 on commercial influence, each partnership is governed by a written contract, and:

• their posts clearly bear, for their entire duration, the label "Publicité" ("Advertising") or "Collaboration commerciale" ("Commercial collaboration");
• content in which a face or figure has been generated by artificial intelligence bears the label "Image virtuelle" ("Virtual image"), and a retouched face or figure bears the label "Image retouchée" ("Retouched image");
• they never present Duro as a treatment, nor as equivalent or preferable to a medicine, and do not announce any quantified or guaranteed results.

A valid creator code may give you a benefit reserved for new subscribers (currently: a 14-day trial instead of 7 on the annual plan): it simply selects the subscription offer presented by Apple. It does not modify an ongoing subscription. A code cannot be exchanged or converted into cash.

10. Your data

The processing of your personal data is described in Duro's Privacy Policy, also accessible in the app (Settings › Privacy).

11. Intellectual property

Duro, its name, logo, texts, illustrations, exercise programmes, sounds and software are protected and belong to ALLURE or its partners. The licence in section 5 does not transfer any ownership rights to you. The answers generated by the coach are provided to you for your personal use.

12. Availability and changes to the service

We do our best to keep Duro running continuously, but cannot guarantee this: maintenance, a provider outage (hosting provider, AI provider, Apple) or lack of network connectivity may interrupt it. The AI coach may be temporarily unavailable. We may change Duro (add, modify or remove features) and require a minimum version of the app, without substantially reducing what is included in an ongoing subscription.

13. Liability

• Duro provides you with a training programme and general information. You alone remain the judge of your practice and of whether to consult a healthcare professional.
• We are not liable for damage resulting from use of Duro contrary to these Terms or to the warnings in section 4, nor for the AI coach's answers when they are used as medical advice.
• To the extent permitted by law, our liability is limited to direct and foreseeable damage.
• Nothing in these Terms limits our liability in the event of gross negligence or wilful misconduct, or personal injury caused by our fault, nor your consumer rights, in particular the legal guarantee of conformity for digital content and services (Articles L224-25-12 et seq. of the French Consumer Code).

14. Suspension and termination

You may stop using Duro at any time, delete your data (Settings › Delete my data) and cancel your subscription with Apple. We may suspend access to the coach or to Duro in the event of a serious breach of these Terms (for example abusive or automated use), after informing you where possible.

15. Clauses required by Apple

• Parties. These Terms are concluded between you and ALLURE only, and not with Apple Inc. ALLURE, not Apple, is solely responsible for Duro and its content.
• Scope of licence. The licence is limited to the use of Duro on Apple-branded products that you own or control, in accordance with the usage rules set out in Apple's Media Services Terms and Conditions.
• Maintenance and support. ALLURE is solely responsible for the maintenance and support of Duro. Apple has no obligation whatsoever to provide any maintenance or support services.
• Warranty. In the event of any failure of Duro to conform to any applicable warranty, you may notify Apple, which will refund the purchase price, if any, of the app. To the extent permitted by law, Apple has no other warranty obligation whatsoever with respect to Duro. Any other claims, losses, liabilities, damages or expenses attributable to any failure to conform are the responsibility of ALLURE.
• Claims. ALLURE, not Apple, is responsible for addressing any claims relating to Duro or its use, including: product liability claims; any failure to conform to any applicable legal or regulatory requirement; claims arising under consumer protection, privacy or similar legislation.
• Intellectual property. In the event of any third-party claim that Duro or its use infringes that third party's intellectual property rights, ALLURE, not Apple, is solely responsible for the investigation, defence, settlement and discharge of that claim.
• Legal compliance. You represent that you are not located in a country that is subject to a United States Government embargo or that has been designated as a "terrorist supporting" country, and that you are not listed on any United States Government list of prohibited or restricted parties.
• Contact. Questions, complaints or claims: ALLURE, 32 rue de Paris, 92100 Boulogne-Billancourt, France, contact@duroapp.fr.
• Third-party terms. You must comply with applicable third-party terms when using Duro (for example those of your mobile operator).
• Third-party beneficiary. Apple and its subsidiaries are third-party beneficiaries of these Terms. By accepting them, you acknowledge that Apple will have the right to enforce them against you as a third-party beneficiary.

16. Changes to the Terms

We may change these Terms. In the event of a significant change, we will inform you in the app at least 30 days before it takes effect. If you do not agree, you may stop using Duro and cancel your subscription. Changes to subscription prices follow Apple's rules; Apple informs you of them and, where necessary, asks for your consent.

17. Governing law and disputes

These Terms are governed by French law. If you are a consumer residing in another European Union country, you retain the protection of the mandatory rules of your country.

If you encounter a problem, please write to us first at contact@duroapp.fr: we will seek an amicable solution. If this fails, you may refer the matter free of charge, within one year of your written complaint, to the consumer mediator to which ALLURE is subject (Articles L611-1 et seq. of the French Consumer Code); the mediator's contact details will be provided to you on simple request at the same address.

Failing agreement, the dispute will be brought before the competent courts in accordance with the ordinary rules of law. The consumer may bring proceedings before the court for the place where they resided at the time the contract was concluded or the harmful event occurred.
