The agreement between you and the publisher of Masir.
These terms govern the use of the Masir mobile application, published by Axel Källgren (sole trader (entrepreneur individuel), SIREN 130 948 169, 35 route de la Borde, 78110 Le Vésinet, France), and of the Masir Plus subscription. Installing or using the application constitutes acceptance of these terms.
Masir is a running coaching application. It generates personalised training plans, measures runs by GPS, analyses performance, and can import runs recorded in the Health app.
Plans are produced by an algorithm based on published training methods, notably Jack Daniels' VDOT methodology. They are computed recommendations, not prescriptions.
Masir is not a medical device and gives no medical advice. The paces, volumes, heart-rate zones and analyses it offers are estimates, for information only.
Running carries a risk of injury. Before starting or resuming training — particularly in case of cardiac or respiratory illness, injury, pregnancy, ongoing medical treatment or prolonged inactivity — consult a healthcare professional.
You remain the sole judge of your own effort. Stopping a session because of pain, faintness or abnormal breathlessness always takes precedence over following the plan.
You undertake to use Masir for its intended purpose and in accordance with the law. The following are prohibited in particular: reverse engineering the software, attempting to circumvent the subscription mechanisms, and using the application to infringe the rights of a third party.
Masir is provided for personal, non-commercial use.
Importing from the Health app is optional. You authorise Masir to read your runs, read-only: Masir never writes anything to Health.
You may revoke the authorisation at any time in Settings → Privacy → Health.
The “Get into running” programme (eight weeks of walking and running), GPS run tracking, history, statistics, run analysis and Health import are available without a subscription, with no time limit.
The complete training plan and the coaching that goes with it: a plan across every distance up to race day, guided fitness tests, pace calibration, adaptation to the unexpected, progression tracking, and calendar export of the plan.
| Plan | Duration | Reference price |
|---|---|---|
| Masir Plus — Monthly | 1 month, renewable | €7.99 per month |
| Masir Plus — Annual | 12 months, renewable | €59.99 per year |
The applicable price is the one shown in the app at the time of purchase, in your local currency. It may vary by country and by applicable taxes.
A two-week free trial is offered on first subscription. At its end, the subscription starts automatically at the chosen price, unless cancelled at least 24 hours before the trial ends.
Any unused portion of a free trial is forfeited if you take out a subscription before it ends.
You may cancel at any time; the subscription stays active until the end of the period already paid for. Refunds are Apple's responsibility and follow its policy: they are requested at reportaproblem.apple.com.
Where a statutory right of withdrawal applies to you — in the European Union, under Article 16(m) of Directive 2011/83/EU, transposed in France by Article L221-28 of the Consumer Code — accepting immediate access to the digital content means waiving that fourteen-day right of withdrawal for the current period.
The processing of your data is described in the privacy policy, which forms an integral part of these terms.
The application, its code, its visual identity and its content are protected by copyright and remain the property of the publisher. The subscription grants a personal, non-exclusive and non-transferable right of use, for the duration of the subscription.
The training data you produce or import remains yours.
The application is provided “as is”. The publisher does not guarantee uninterrupted availability, in particular in the event of network failure or operating-system changes.
Features may change. If a feature included in Masir Plus were removed without an equivalent, you would be able to cancel at no cost.
The publisher cannot be held liable for damage resulting from use of the application other than as intended, from inaccuracy in data supplied by third-party services, or from an injury occurring during training.
Nothing in these terms excludes the publisher's liability in case of gross negligence or wilful misconduct, nor the mandatory statutory guarantees available to consumers, including the legal guarantee of conformity.
These terms are governed by French law. In the event of a dispute, an amicable solution will be sought first, by writing to axel.kallgren@gmail.com.
Failing agreement, you may refer the matter free of charge to a consumer mediator. The French courts have jurisdiction, without prejudice to the protective rules applicable to consumers, which in particular allow a consumer to bring proceedings in the courts of their own country of residence.
These terms may be amended. Any substantial change will be flagged in the app. Continuing to use the application after notification constitutes acceptance.
