Terms of Use

Last updated: April 2026

1. Scope

These Terms of Use apply to the use of the web application Cervio (hereinafter "App"), which is provided at the domain cervio.health. By using the App, you agree to these Terms of Use. If you do not agree, please refrain from using the App.

2. Description of Services

Cervio is a free wellness and movement app that serves as a training companion for neck mobility, posture and everyday movement. The App offers in particular:

Structured presentation of exercises for neck, posture and everyday mobility
Timer and set tracking during training
Voluntary body-awareness diary and optional check-ins for mood, energy and sleep
Local storage of training history on the user's device
Visualization of training progress

The App is not a medical device within the meaning of Regulation (EU) 2017/745 (MDR) and serves exclusively general movement, fitness and wellbeing purposes. It does not provide medical diagnoses, does not give therapeutic recommendations, and does not replace medical advice, diagnosis or treatment.

2.1 Cloud Synchronization (Optional)

Cervio optionally offers the ability to synchronize training data via a Supabase-based cloud service. This feature requires the creation of a user account (email/password or social login via Google, Apple, or Facebook). When using cloud synchronization:

Synchronization is voluntary — the App can be used entirely without an account and exclusively with local storage.
Synchronized data is stored on Supabase servers (hosted on AWS in the EU).
The user can delete their account and all associated cloud data at any time.
The operator does not guarantee the continuous availability of the cloud service.

2.2 Physiotherapist Mode (joint controllership)

Cervio offers a dedicated physiotherapist mode that enables qualified physiotherapists to create individual training plans for their patients and monitor their progress. In this mode, a joint controllership under Art. 26 GDPR applies. The mode includes:

Plan creation: Physiotherapists can compose individual training plans and share them via a code system.
Code system: Patients enter a code generated by the therapist to activate a personalized plan.
Dashboard: Therapists can view training progress and, if shared by the patient, further progress data.

Within the physiotherapist mode the medical responsibility lies exclusively with the physiotherapy practice. Cervio is a pure technical infrastructure provider. The practice is additionally bound by the German documentation obligation (§ 630f BGB, 10-year retention) for its own patient records.

2.3 Physio Chat

Within the physiotherapist mode, a bidirectional chat function is available for physiotherapists and their patients to exchange messages. The following applies to the physio chat:

The chat serves organizational communication related to training and does not replace medical advice or emergency communication.
Messages are transmitted and stored via the cloud service (Supabase).
Both parties are responsible for the content of their own messages.
The operator assumes no responsibility for the content of chat communications.

2.4 Data Export and Import

Cervio allows the export and import of training data. The user can export their stored data (e.g., as a JSON file) and re-import it on another device or after a reinstallation. The following applies:

The export serves personal data backup and portability.
The user is responsible for the secure storage of exported data.
During import, existing local data is supplemented or overwritten depending on the settings.
The operator assumes no liability for data loss due to faulty import or corrupted export files.

2.5 Multi-Profile Support

Cervio supports the management of multiple user profiles on one device. This allows, for example, family members to share the App, with each profile maintaining its own training data and settings. The following applies:

Each profile is stored and managed separately.
Switching between profiles is done within the App.
Each user is responsible for their own profile and its contents.
Deleting a profile irrevocably removes all associated local data.

3. Medical Disclaimer

Important Notice — Please read carefully:

Cervio is a wellness and movement app and not a medical device. The exercises, training plans, and information presented are for general movement, fitness and wellbeing only. They do not constitute medical advice, diagnosis, or treatment and under no circumstances replace the professional assessment by a physician, physiotherapist, or other qualified healthcare provider.

In particular:

The App does not replace a medical examination or diagnosis.
If you have existing conditions, injuries, are pregnant, or are in doubt, obtain medical or physiotherapeutic clearance before starting an exercise program.
If pain, dizziness, nausea, or other symptoms occur during training, stop the exercise immediately and seek medical advice for persistent symptoms.
The operator assumes no liability for health damages resulting from performing the exercises presented in the App, to the extent permitted by law.
The body-awareness diary in the App is for personal documentation and is not a diagnostic tool.

4. Usage Requirements

Use of the App requires the following:

You are at least 16 years old. Persons under 16 may only use the App under the supervision and with the consent of a parent or legal guardian.
It is strongly recommended to obtain medical or physiotherapeutic clearance for the training program presented before using the App.
You have a compatible web browser with JavaScript and localStorage enabled.

Use of the App is at your own risk. You are solely responsible for performing the exercises correctly and within your physical capabilities.

5. Intellectual Property

All content of the App — including but not limited to text, graphics, logos, icons, exercise descriptions, program code, and design — is protected by copyright and is the property of the operator or the respective rights holders.

Use of the App grants you a simple, non-transferable, revocable right of use for personal, non-commercial purposes. In particular, the following is prohibited:

Copying, modifying, or redistributing the App or parts thereof.
Using the App for commercial purposes.
Circumventing technical protection measures or decompiling the source code (unless expressly permitted by law).

6. Limitation of Liability

The operator provides the App free of charge and without warranty ("as is"). To the extent permitted by law, liability is limited as follows:

For damages arising from the use or inability to use the App, the operator is liable only in cases of intent and gross negligence.
Liability for indirect damages, consequential damages, and lost profits is excluded to the extent permitted by law.
The operator is not liable for the accuracy, completeness, or timeliness of the exercises and information presented in the App.
The operator is not liable for the loss of locally stored data (e.g., due to clearing browser data, changing devices, or technical malfunctions).

This does not affect liability for damages resulting from injury to life, body, or health based on an intentional or negligent breach of duty, as well as liability under the Product Liability Act.

7. Data Protection

Protecting your data is important to us. All training data and symptom records are stored exclusively locally on your device unless you activate the optional cloud synchronization.

Detailed information can be found in our Privacy Policy.

8. Availability

The operator strives to provide the App with minimal interruption. However, there is no entitlement to continuous availability. In particular, the operator reserves the right to:

Modify, expand, or discontinue the App at any time without prior notice.
Perform maintenance that may result in temporary unavailability.
Restrict access to the App in the event of a violation of these Terms of Use.

Since the App can also function offline as a Progressive Web App, basic functionality remains available with an existing installation even without an internet connection.

9. Changes to the Terms of Use

The operator reserves the right to amend these Terms of Use at any time. The current version is always available at this URL. In the event of material changes, the update date at the top will be adjusted.

Continued use of the App after changes to the Terms of Use constitutes acceptance of the amended terms.

10. Severability Clause

Should any provision of these Terms of Use be or become wholly or partially invalid, the validity of the remaining provisions shall not be affected. In place of the invalid provision, a valid provision shall be deemed agreed upon that most closely approximates the economic purpose of the invalid provision.

11. Applicable Law

The law of the Federal Republic of Germany applies, excluding the UN Convention on Contracts for the International Sale of Goods (CISG). If you are a consumer and have your habitual residence in another country, the mandatory consumer protection provisions of that country remain unaffected.

The place of jurisdiction is, to the extent permitted by law, the registered office of the operator (see Legal Notice).
