Terms and Conditions

This is a legal agreement between users of this service (“you”) and HippoSphere UG. This agreement governs your use of MediHippo (hereinafter referred to as “the service”). In this document, “we” and “our” refer to HippoSphere UG, its employees, and trusted third-party contractors.

To use this service, you must be at least 18 years old. If you are under 18, you may only use this service with the consent and under the supervision of a parent or legal guardian.

Privacy Policy

Please read our Privacy Policy to understand what data we collect when you use MediHippo, why we collect it, and the limited ways in which we may share it.

Virtual Goods and Coins

Within the service, you may purchase a non-exclusive, non-transferable, and revocable right to use virtual coins (“HippoCoins”) with real money. These coins entitle you to use certain features in the app, particularly AI-powered services and other digital content. Coins are not legal currency and have no real-world monetary value outside the MediHippo platform.

Coins can only be purchased through authorized channels—this includes our web app, the Google Play Store, and the Apple App Store. Buying or trading coins outside of these platforms is not permitted. Transferring, gifting, or reselling coins to other users is only allowed when explicitly enabled within the service.

No Refunds

All coin purchases are final. Refunds are only issued when required by law. By purchasing, you expressly agree that delivery of digital content (coins) begins immediately upon purchase and that you waive your statutory right of withdrawal (§ 356 para. 5 BGB).

Management and Changes

We reserve the right to modify, adjust, or remove coins and their usability within the service at any time. This includes introducing new features, changing coin usage, or switching to alternative payment systems. We are not liable for any resulting restrictions or losses, to the extent permitted by law.

Pricing and Payment Terms

Unless explicitly stated otherwise, the prices listed within the web app, Google Play Store, or Apple App Store at the time of purchase apply. All prices include applicable VAT.

We reserve the right to adjust prices at any time based on market conditions or operational needs. Changes apply only to future billing periods and will be communicated to you in advance via the web app or relevant app store.

Depending on the product, immediate payment may be required. Payments are processed through the available payment options in the web app or app store. Access to paid content is only granted after successful payment.

Payment Default

If payment is not made on time, you will automatically be in default without further notice (§ 286 para. 2 BGB). In case of default, we reserve the right to:

  • Temporarily or permanently restrict access to paid features,
  • Charge statutory default interest (§ 288 BGB),
  • Impose a flat reminder fee of €5.00 per notice, and
  • Terminate the contract for cause, if necessary.

Once all outstanding amounts are paid, access will be reinstated. Additional damages caused by the delay may be claimed separately.

Subscription Terms

MediHippo offers a subscription model that gives you access to additional features and digital content. The subscription includes, among other things, a monthly allocation of virtual coins (“HippoCoins”) that allow you to use AI features in the app. Details on content, pricing, and duration can be found in the web app or app stores (Google Play, Apple App Store).

Renewal and Cancellation

Subscriptions renew automatically for the same term (e.g., monthly or yearly) unless canceled at least 24 hours before the current period ends. Cancellation can be made as follows:

  • For purchases via Google Play: in your Google account settings
  • For purchases via Apple App Store: in your Apple ID subscription settings
  • For purchases via the web app (Stripe): in your user account under “My Account” > “Subscription”

After cancellation, you will retain access until the end of the already paid period. No partial refunds will be given unless required by law.

Right of Withdrawal

Purchases via App Stores

For subscriptions made via the Google Play Store or Apple App Store, the respective platform provider’s policies apply regarding the right of withdrawal and refunds. Please check your rights and options there. We do not have control over these processes.

Purchases via the Web App (Stripe)

For subscriptions made through our web app, the statutory right of withdrawal under § 355 BGB applies. You have the right to cancel the contract within 14 days without giving any reason.

Since the provided content—especially HippoCoins, additional storage, ad-free usage, and other digital services—is made available immediately after the contract is concluded, you expressly agree, by accepting these Terms and Conditions, that the execution of the contract begins before the withdrawal period ends and that your right of withdrawal therefore expires (§ 356 para. 5 BGB).

A subscription via the web app is only possible if you agree to these conditions during the checkout process.

Account Expiration

To operate our servers efficiently and keep costs low, we periodically delete inactive account data. Your account and learning progress may be deleted if there is no activity for one year.

Standard procedure for inactive account expiration:

  1. Pre-notification: 30 days before deletion due to inactivity, we will send an email notification to the address you provided. This gives you a chance to log in and keep your account active.

  2. Final notification: If you don’t log in within 30 days of the first email, we’ll send a final reminder 5 days before permanent deletion.

  3. Deletion: If there is still no activity, your account and all associated data will be permanently deleted.

  4. Data recovery: Once deleted, recovery of your account and data is no longer possible.

  • Legality and Rights: You own all necessary rights of use for the submitted content, including but not limited to copyright, trademark, patent, and other forms of intellectual property.

Use of HippoSync

Synchronization with Third-Party Applications

When using our app, you may sync with third-party applications that support the WebDAV format. This allows files to be downloaded to your device or uploaded from your device to the cloud.

At no point do we access the contents of synchronized data. All content remains solely on your device. We only store your learning progress, independent of the actual content.

  1. Intellectual Property Protection: The provisions outlined in Acceptance of Content apply equally to files synchronized using the WebDAV interface. You may not sync content for which you lack the necessary rights or licenses.

  2. Third-Party Service Terms: When using a provider that supports WebDAV, you must comply with their terms, policies, and legal obligations. This includes any access, usage, or storage rights the provider asserts. We accept no liability for violations of third-party terms.

You are solely responsible for having the required rights and licenses for synchronized content and for adhering to the respective provider’s policies.

Access to the Service

You may access MediHippo via your browser or through authorized clients on the Google Play Store or Apple App Store.

Since the service is currently provided free of charge, we reserve the right to restrict or revoke your access at any time at our discretion. However, we will not do so without prior notice in accordance with the provisions below:

Notice of Access Restrictions

  1. Advance Notification: If we plan to make significant changes to service access or restrict your account, we will notify you at least 14 days in advance via email or in-app notice.

  2. Right to Object: If you have concerns or objections, you may submit them within 7 days of receiving the notice. We will review and respond appropriately to any legitimate concerns.

Violations & Law Enforcement

If you violate these Terms of Use, we reserve the right to suspend or delete your account at our sole discretion. If your actions are illegal, we also reserve the right to report them to the authorities. We will share your information with third parties if legally required.

Fees and Funding

Currently, the service is free to use. Due to rising hosting costs, we may introduce a “freemium” model in the future, where basic accounts remain free and advanced features or ad-free usage may require payment.

Changes to These Terms

If significant changes are made to these Terms, you will be notified via an in-app message, during synchronization, or by email.

Transfer of Rights and Obligations

In the event of a business acquisition, restructuring, or insolvency, we reserve the right to transfer these rights and obligations to a third party or new legal entity.

Disclaimer of Liability

Your Responsibility: Use of MediHippo is at your own risk and discretion. While we strive for integrity, security, and availability, we cannot guarantee that the service will always be error-free or uninterrupted.

No Warranty: The service is provided “as is” and “as available”, without any express or implied warranties. This includes, but is not limited to, implied warranties of merchantability, fitness for a particular purpose, or non-infringement.

Backups: You are solely responsible for backing up your data. We are not liable for any data loss or damage.

No Guarantee: We do not guarantee that the service will always meet your expectations, be uninterrupted or error-free, that all issues will be resolved, or that the service will be free of harmful components.

Availability and Technical Changes

We aim to provide a reliable and high-quality service. However, temporary interruptions may occur due to technical, security, or operational reasons—such as maintenance, updates, or unforeseen system events.

We reserve the right to adapt, improve, or suspend features, content, or technical components of the service if necessary to improve, secure, or maintain platform functionality. We will ensure that no disproportionate disadvantages arise for you.

There is no entitlement to uninterrupted service access.

Language and Interpretation

These Terms of Use are provided in multiple languages to enhance accessibility for international users. However, only the German version is legally binding. In the event of inconsistencies or discrepancies between the German and translated versions, the German version shall prevail.

Applicable Law and Jurisdiction

The law of the Federal Republic of Germany shall apply, excluding the United Nations Convention on Contracts for the International Sale of Goods (CISG).

Where legally permissible, the place of jurisdiction for all disputes arising from or in connection with this agreement is the registered office of HippoSphere UG.

Consumers residing in the EU may also use the European Commission’s Online Dispute Resolution (ODR) platform, in accordance with Regulation (EU) No. 524/2013: https://ec.europa.eu/consumers/odr

Limitation of Liability

Unless otherwise required by law, we shall not be liable for any direct or indirect damages of any kind arising from the use or inability to use MediHippo. This includes, but is not limited to, data loss, corrupted data, business interruptions, or financial losses, even if we have been informed of the possibility of such damages.

This limitation of liability does not apply in cases of intent or gross negligence.
