Terms of Service for the Trainer App and Trainer Membership (iOS and Android)
Last updated: April 15, 2026
1. Scope
These Terms of Service ("Terms") govern your use of the Trainer app ("Trainer" or the "App") and any paid memberships, subscriptions, or other in-app purchases offered in connection with the App.
By downloading, installing, purchasing, or using Trainer, you agree to these Terms. If you do not agree to these Terms, you must not use the App.
To the extent Trainer is offered through the Apple App Store and/or Google Play, your use of the respective platform may also be subject to the terms of the relevant platform operator.
2. Trainer App
Trainer is a fitness app for planning strength training, tracking workouts, and reviewing your training progress.
Trainer is intended for general fitness, motivation, and workout logging purposes only. Trainer is not a medical device and does not provide medical advice, diagnosis, or treatment.
No separate user account with the developer is required to use Trainer. Paid access, where offered, is managed through the store account through which the relevant purchase was made.
In the current version, most workout and app data is stored locally on your device. Certain features may vary depending on platform, operating system, device version, or app version, or may only be available on certain platforms.
3. Trainer Membership, Subscriptions, and In-App Purchases
Some features of Trainer may require a paid Trainer Membership, a subscription, or another in-app purchase.
Prices, billing intervals, free trials, introductory offers, and the availability of individual products are shown in the Apple App Store and/or Google Play at the time of purchase and may vary by country, region, platform, and current offer.
Payment is processed through the store through which you complete the purchase. Depending on the platform, the purchase may be charged to your Apple Account or to the account or payment profile used with Google Play.
Auto-renewing subscriptions renew according to the rules and settings of the relevant store unless they are cancelled or auto-renewal is turned off in time before the end of the current billing period.
You can manage or cancel subscriptions after purchase in your Apple Account settings or in the subscription settings of Google Play.
Where provided for by the relevant store, any unused portion of a free trial is forfeited when you purchase a paid subscription or other paid purchase before the trial ends.
Trainer uses RevenueCat to display offerings, verify memberships or entitlements, and help restore previous purchases. Billing, renewal, cancellation, and any refund process are handled by the relevant store and not by the developer or RevenueCat.
You are not entitled to permanently unchanged prices, to specific future features, or to the continued existence of any particular membership model.
4. Local Storage, Data Availability, and Backups
In the current version, Trainer stores most workout data locally on your device rather than in a developer-operated user account.
You are responsible for keeping your device secure and, where the App provides such features, for creating your own backups or exports of your workout data.
The developer does not guarantee that locally stored workout data can be fully restored after deleting the App, changing devices, losing a device, hardware failure, reinstalling an operating system, or any other disruption.
Where Trainer offers export, import, or restore features, you are responsible for keeping exported files safe and for storing them only in storage locations or services you choose.
The restoration of paid memberships or purchases may depend on the mechanisms provided by the relevant store and by RevenueCat. This does not mean that locally stored workout data can also be restored automatically.
5. Health and Safety Disclaimer
You use Trainer at your own risk.
Before starting, continuing, or changing training, you should consult a qualified medical professional, especially if you are injured, pregnant, postpartum, under medical treatment, or have health concerns, pre-existing conditions, or any other risk factors.
Stop training and seek professional advice if you experience pain, dizziness, shortness of breath, or other unusual symptoms during or after training.
The workouts, plans, recommendations, progress indicators, and other content in Trainer are provided for general informational and fitness purposes only. They do not replace professional medical advice, diagnosis, or treatment.
The developer does not guarantee that any workout, plan, training recommendation, progression, or other suggestion is appropriate for your individual physical condition, health, or goals.
6. Acceptable Use
You may use Trainer only in compliance with applicable law.
In particular, you must not:
- misuse the App,
- interfere with the operation of the App or related services,
- attempt to gain unauthorized access to features, systems, or content,
- circumvent protective mechanisms,
- decompile, reverse engineer, or otherwise technically analyze the App except to the extent expressly permitted by mandatory law.
7. Availability, Changes, and Termination
Trainer is provided on an "as is" and "as available" basis.
The developer may add, change, suspend, or remove features, memberships, pricing, content, compatibilities, or parts of the App at any time.
You are not entitled to uninterrupted availability of the App or to the permanent availability of specific features, content, integrations, or membership models.
The developer may suspend or terminate access to the App or to paid features if you materially breach these Terms or misuse the App.
8. Intellectual Property
All content and features of Trainer, including text, graphics, exercise visuals, design elements, software, trademarks, logos, and other protected content, are owned by the developer or the respective rights holders and are protected by applicable intellectual property laws.
These Terms do not transfer ownership of the App or its content to you. You are granted only a limited, revocable, non-transferable right to use the App in accordance with these Terms and the applicable store rules.
9. Limitation of Liability
To the fullest extent permitted by law, the developer is not liable for indirect, incidental, special, or consequential damages, lost profits, or other financial losses arising out of or related to your use of, or inability to use, Trainer.
This also applies in particular to damages resulting from workouts, plans, recommendations, or guidance in the App not being suitable for your individual situation, unless liability is mandatory under applicable law.
Nothing in these Terms limits liability for intent, gross negligence, injury to life, body, or health, or any other liability that cannot be excluded or limited under mandatory law.
10. Changes to These Terms
These Terms may be updated from time to time.
If you continue to use Trainer after an update, the then-current version applies to your further use of the App to the extent permitted by applicable law.
Mandatory legal notice or consent requirements remain unaffected.
11. Governing Law and Venue
These Terms are governed by the laws of the Federal Republic of Germany, excluding conflict-of-law rules, unless mandatory consumer protection laws in your country of residence provide otherwise.
If you are a merchant, a legal entity under public law, or a special fund under public law, the place of jurisdiction is the developer's place of business, to the extent permitted by law.
