Lambly: Legal
End User Licence Agreement
For the Lambly app · Last updated: 7 September 2026
1. Scope
By downloading, installing or using Lambly („the App“) you agree to this licence agreement. If you do not agree, please do not use the App. Your contracting party is Luis Fynn Schenk (Lufy Studios), Alter Hohlweg 5, 58285 Gevelsberg, Germany. Apple is not a party to this agreement.
2. Licence
You receive a simple, non-exclusive, non-transferable and revocable right to use the App on the Apple devices that you own or control, within the scope of Apple’s App Store Terms of Service. The App is not sold to you; all rights not expressly granted to you are reserved.
3. Restrictions
You may not:
- copy, modify or translate the App, or create derivative works from it;
- reverse engineer, decompile or disassemble it, except where this is permitted by mandatory law;
- rent, lease, lend, resell or sublicense it;
- use it in any manner that violates applicable law.
4. Content in the Friends feature
If you use the Friends feature, the display name you publish is visible to anyone who knows your friend code. Do not publish a name, and do not send content through requests or challenges, that is unlawful or offensive or that infringes the rights of others. We may remove published content and block a friend code that is used in this way.
5. Lambly Pro
Four features require a subscription: the full history with monthly analysis, the gym analysis with templates, exercise history and personal records, all skills above the beginner level, and data export as a PDF report. Recording training, meals, water, weight and sleep is free, as is iCloud sync.
Two terms are offered: a monthly and an annual subscription. The prices that apply are shown in the purchase dialog in the App and on the product page in the App Store; they depend on your region and include the VAT payable there.
Billing runs through your Apple ID upon purchase confirmation.
The subscription renews automatically for the same term unless it is cancelled at least 24 hours before the end of the current period. The charge for the renewal is made within the last 24 hours of that period.
You can manage and cancel it at any time under Settings → your name → Subscriptions. Cancellation takes effect at the end of the current period; until then the Pro features remain available.
An amount paid for the current period is not refunded pro rata upon cancellation.
Apple announces price changes in advance. You must consent to an increase; without your consent the subscription ends when the current period expires.
On a further device you reactivate an existing subscription via „Restore Purchases“, provided the same Apple ID is used.
6. Who you buy from, withdrawal and refunds
Your contracting party for the purchase of the subscription is Apple, not us. In distribution through the App Store, Apple acts as the seller and handles payment, invoicing and refunds.
For your right of withdrawal this means: it is directed at Apple and governed by the terms of the App Store, not at us. You request refunds via reportaproblem.apple.com or Apple’s support. We can neither view nor refund a payment.
For the App itself we remain your point of contact. In the event of defects, write to info@lufystudios.de – regardless of who handled the payment.
7. Not a medical device
Lambly is not a medical device and gives no medical advice. Training plans, calorie targets, exercise descriptions and other suggestions serve as general information. Consult a doctor before starting a new training, nutrition or sleep programme, particularly if you have existing health conditions. Use of the training and health features is at your own responsibility.
8. Intellectual property
The App, including its design, source code, texts and exercise descriptions, is protected by copyright and belongs to Luis Fynn Schenk (Lufy Studios).
9. Term and termination
This agreement applies until it is terminated. It ends automatically if you breach its provisions. You may end it at any time by deleting the App; you remove your account under Settings → Delete Account.
10. Warranty and liability
The App is provided in the form in which it is available. We do not warrant that it runs free of errors or without interruption, or that health and fitness values – including those read from Apple Health – are entirely accurate.
We are liable without limitation in cases of intent and gross negligence, and for injury to life, body or health. In cases of ordinary negligence we are liable only for the breach of a material contractual obligation and limited to the foreseeable damage typical for this type of contract. Liability under the German Product Liability Act remains unaffected. Statutory warranty rights of consumers likewise remain unaffected.
11. Relationship with Apple
This agreement is between you and us, not with Apple. Apple is not responsible for the App or its content and owes neither support nor maintenance. In the event of a failure to conform to any applicable warranty, you may notify Apple, and Apple will refund the purchase price to you through the App Store; beyond that, Apple has no warranty obligation whatsoever. We, and not Apple, are responsible for third-party claims in connection with the App – including product liability, consumer protection and infringement of intellectual property. Apple and its subsidiaries are third-party beneficiaries of this agreement and are entitled to enforce it against you.
12. Changes
We may adapt this agreement. We will give notice of material changes in the App or on our website; continued use after they take effect constitutes acceptance.
13. Governing law
German law applies, excluding the UN Convention on Contracts for the International Sale of Goods. Mandatory consumer protection provisions of your country of residence remain unaffected.
