Terms of Use
Last updated: 13 August 2026
1. Scope
These terms govern the use of the Gotthard Strength web app, operated by Markus Lanz, Seestrasse 49, 6052 Hergiswil NW, Switzerland (“we”). By creating an account you accept these terms.
2. The service
Gotthard Strength provides individualized, periodized strength and conditioning planning: training plans, target weights, logging and progress analysis. The app supports the coaching relationship with your coach; it does not replace it. The app does not provide medical advice, diagnosis or treatment.
3. Your account
You agree to provide accurate information and to keep your login credentials confidential. Your account is personal and may not be shared or transferred.
4. Subscription and prices
Access to the app is offered as a monthly subscription. The price that applies is the one shown in the app and on the payment page when you subscribe. Online Coaching can be added, likewise as a monthly subscription. It requires a running app subscription and cannot be bought on its own. We may also grant access free of charge or for a limited time through access codes. This creates no entitlement to future free use. We announce price changes at least 30 days in advance. They apply from the next billing period. If you do not agree, you may cancel before that period begins.
5. Payment
Payments are processed by Stripe Payments Europe Ltd. Your payment details are collected and processed by Stripe; we do not store card data. The amount is charged in advance at the start of each billing period. Invoices and receipts are available in the customer portal, which you open from the app. If a payment fails it is retried over several days and your access remains active in the meantime. If payment ultimately fails, access is suspended.
6. Term, cancellation and refunds
The subscription runs for one month and renews automatically for a further month unless you cancel. You may cancel at any time with effect from the end of the current period, without notice period and without giving reasons — in the customer portal, which you open in the app under “Subscription”. Your access remains until the end of the period you have paid for. After that, access is suspended but your data is kept: if you subscribe again later, you can continue your plan where you left off. Deletion of your account is requested separately (section 11). Periods already paid for are not refunded pro rata. Mandatory statutory rights remain reserved. Under Swiss law there is no statutory right of withdrawal for contracts concluded online. We may suspend or end the subscription in case of non-payment or misuse of the service.
7. Health and personal responsibility
Strength training carries inherent risks. You train at your own risk and are responsible for your own health. Consult a doctor before starting, especially if you have pre-existing conditions, injuries or are unsure about your health. Target weights suggested by the app are computed from your own logged performance — you remain responsible for correct technique and for deciding whether an exercise is safe for you. Never perform an exercise that causes pain or that you cannot execute with control.
8. Availability
The app is provided as is. We aim for high availability but do not guarantee uninterrupted operation. We may change, interrupt or discontinue features at any time, and will announce material changes within the app where reasonable.
9. Intellectual property
All content of the app — including the training templates and program logic we created, the texts, the design and the Gotthard Strength brand — remains our property. You may use the app only for its intended purpose.
10. Liability
To the extent permitted by law, we exclude liability for indirect damage and consequential damage, for training outcomes, and for injuries resulting from incorrect execution of exercises or from ignoring section 7.
11. Termination
You may stop using the app and request deletion of your account at any time; this also deletes your training data. A running subscription is cancelled separately under section 6. We may suspend or delete accounts in case of misuse of the service.
12. Changes to these terms
We may amend these terms. We will announce material changes in the app. If you continue to use the app after changes take effect, the amended terms apply. Section 4 governs price changes.
13. Governing law and jurisdiction
Swiss law applies, excluding its conflict-of-law rules. Place of jurisdiction is the registered seat of the operator, subject to mandatory statutory places of jurisdiction.
