Terms of Service for Resero
Welcome to Resero! These Terms of Service ("Terms") govern your use of the Resero mobile application (the "App"), provided by Imarum GmbH ("we," "us," or "our").
An account is not required to use the App. By using our App, you agree to be bound by these Terms. If you do not agree to these Terms, please do not use the App.
§1. Description of Service
Resero is a workout builder application that allows users to create and manage custom fitness routines using intervals and repetition-based sets, as well as access predefined workout plans and exercises ("App Content").
The App is solely intended for personal organization, information, and training support. Imarum GmbH does not provide medical or professional fitness advice.
§1b. Health Notice & Personal Responsibility
(1) No medical advice: App Content does not constitute medical, health, or clinical advice and does not replace examination by, or advice from, a licensed medical professional.
(2) Medical clarification: Physical training involves risks of injury or health impairment. Before starting a workout offered in the App or created by you, you are advised to seek medical advice. This applies in particular during pregnancy, in the case of illness or injury, or if you are exposed to unusually high physical strain. If you experience dizziness, nausea, chest pain, or discomfort during training, you must stop immediately.
(3) Execution and training environment: You are solely responsible for:
- realistically assessing your own physical capabilities and selecting suitable intensity levels;
- performing all exercises with correct form and the necessary safety precautions; and
- ensuring a safe training environment free of obstacles or hazards.
These notices are intended to protect your health and clarify your personal responsibility when using the App.
§2. No User Accounts & Local Storage
To prioritize your privacy, the App does not require a user account, an email address, or a login.
On-Device Data: All User Content—including your custom workout structures, intervals, repetition sets, and completed workout history—is stored exclusively on your physical device. We do not transmit, backup, or store your workout data on our servers.
Data Loss Warning: Because we do not have access to your data, we cannot recover it for you. However, if you have third-party cloud backups enabled, your App data may be preserved. If you delete the App, clear its cache, or lose your device without an active backup, all your created workouts and progress will be permanently lost.
§3. Technical Analytics (Firebase Crashlytics)
The only external data communication the App performs is with Firebase Crashlytics. This service collects anonymous technical logs (such as device type, OS version, and stack traces) in the event of an App crash. This information is used strictly for debugging and improving App stability and does not include your specific workout data or personal identifiers.
§4. Prohibited Conduct
You agree not to use the App to:
- Attempt to reverse-engineer, decompile, or otherwise discover the source code of the App.
- Introduce viruses, spam, or any other malicious code.
- Use the App for any purpose other than its intended personal, non-commercial use.
§5. Intellectual Property
All rights, title, and interest in and to the App itself, including its design, software, branding, and content (excluding User Content), are the exclusive property of Imarum GmbH and its licensors.
§6. Disclaimer of Warranties
The App is provided "as is" and "as available" without any warranties of any kind, either express or implied. We do not warrant that the App will be accurate, reliable, uninterrupted, or error-free. Your use of the App is at your sole risk.
§7. Limitation of Liability
(1) Imarum GmbH has unlimited liability for damages arising from injury to life, body, or health caused by an intentional or negligent breach of duty by Imarum GmbH, its legal representatives, or vicarious agents, and for other damages caused by intentional or grossly negligent breaches of duty.
(2) In cases of slight negligence, Imarum GmbH is liable only for the breach of an essential contractual obligation ("Kardinalpflicht"). An essential contractual obligation is an obligation whose fulfillment is required for proper performance of the contract and on whose compliance you may regularly rely. In this case, liability is limited to the foreseeable, typical contractual damage.
(3) In all other respects, liability of Imarum GmbH - regardless of legal grounds - is excluded. This applies in particular to injuries or damages resulting from improper exercise execution, non-compliance with safety instructions, or an unsuitable training environment on the user's side.
§8. Governing Law and Jurisdiction
These Terms shall be governed by and construed in accordance with the laws of the Federal Republic of Germany, without regard to its conflict of law principles. You agree to submit to the exclusive jurisdiction of the courts located in Munich, Germany, to resolve any legal matter arising from these Terms.
§9. Changes to these Terms
We may update these Terms to reflect changes in the App's functionality. Since we do not collect contact information, updates will be made available within the App. Your continued use after an update constitutes acceptance of the new Terms.
