Terms of Service for the Trainer App and Trainer Membership (iOS and Android)
Last updated: August 3, 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 me 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.
Who your contract partner is: For the use of the app, these Terms apply between you and me. The purchase of the app as well as all in-app purchases and subscriptions, however, are not concluded with me. In that respect your contract partner is Apple Distribution International Ltd., Hollyhill Industrial Estate, Hollyhill, Cork, Ireland, when obtained through the Apple App Store, and Google Commerce Limited, 70 Sir John Rogerson's Quay, Dublin 2, D02 R296, Ireland, when obtained through Google Play. Prices, payment, billing, automatic renewal, cancellation, refunds and any statutory right of withdrawal are therefore governed by the terms of the respective store operator and must be asserted against them. Your statutory rights against the store operator are not restricted by these Terms.
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 me 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 user account operated by me.
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.
I do 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.
I do 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
For the duration of your subscription I provide the updates necessary to maintain the conformity of the app; this includes security updates. If you do not install a provided update within a reasonable period, I am not liable for defects that result solely from the absence of that update; this applies only if I informed you about its availability and about the consequences of not installing it.
Beyond that, I may develop, change or discontinue features, content and compatibilities, provided this is reasonable for you taking my interests into account and the contractually agreed scope of your subscription is not changed to your detriment.
You are not entitled to uninterrupted availability of the App or to the permanent availability of specific features, content, integrations, or membership models.
I 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 me 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
I am liable without limitation for damage caused intentionally or by gross negligence by me, my legal representatives or the people I engage to perform.
I am also liable without limitation for damage arising from injury to life, body or health, for damage for which I am answerable under the German Product Liability Act, and to the extent of any guarantee I have given.
In cases of simple negligence I am liable only for the breach of a material contractual obligation. Material contractual obligations are those obligations whose fulfilment makes achieving the purpose of the contract possible in the first place, on whose observance you may therefore rely, and whose breach endangers the achievement of the purpose of the contract. In such cases my liability is limited to the foreseeable damage typical for this type of contract at the time the contract was concluded.
For loss of data I am liable, within the scope of the preceding paragraphs, only up to the amount that would have been incurred to restore the data had it been backed up properly and regularly. The first two paragraphs of this section remain unaffected.
Any further liability is excluded. The statutory rules on the burden of proof remain unaffected. Your statutory rights in respect of defects in the app, and your rights against the respective store operator, are not restricted by this section.
10. Changes to These Terms
I may change these Terms if and to the extent this is necessary to adapt them to a changed legal situation or case law, to changed requirements of the app store operators, or to technical and functional developments of Trainer, and the change is reasonable for you taking my interests into account.
The scope of the service I owe and the balance between service and payment are not changed by this. I will inform you about a planned change at least 30 days in advance in the app or through the update description and point out the changes to you. A change becomes effective towards you only if you expressly agree to it; if you do not agree, the previous version continues to apply to you.
Prices, billing, renewal and cancellation of your subscription are governed exclusively by the terms of the respective store operator and cannot be changed through these Terms.
11. Position of Apple and Google
These Terms are concluded between you and me, not with Apple or Google. I alone am responsible for maintenance and support, not Apple or Google; please direct support requests to joe@waldow.app. Apple and Google have no warranty obligation with respect to the app and are not responsible for claims relating to the app, such as product liability, defects in title or consumer protection claims. In the event of third-party claims that the app infringes their intellectual property rights, I alone am responsible for investigation, defence and settlement.
Apple and its subsidiaries are third-party beneficiaries of these Terms and may enforce them against you.
You represent that you are not located in a country subject to a US government embargo and that you are not on any US government list of prohibited or restricted parties.
12. 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 my place of business, to the extent permitted by law.
