These Terms of Use (these “Terms”) govern your use of the app “Ebbio” (the “App”), provided by Cyver Labs (the “Operator”). You are deemed to have agreed to these Terms at whichever comes first: the moment you tap the “I agree to the Terms of Use” button shown on first launch (or a similar screen), or the moment you use any feature of the App, whether or not that button is shown.
The App is a study-support tool that manages your review schedule using spaced repetition (the FSRS algorithm). Learning Data is stored primarily on your device and is not sent to the Operator's servers. For details on how information is handled, see the separate Privacy Policy.
There is no specific age requirement to use the App. If you are a minor, please use the App only with the consent of a parent or legal guardian.
Ebbio Trial is subject to limits on the number of Items, the length of your streak, and other features. These limits may change, including for product-improvement reasons.
You may obtain the Ebbio lifetime license through a one-time in-app purchase via the App Store or Google Play. Apple, Google, or another applicable store operator handles the purchase process, payment information, and purchase records; the Operator does not receive your payment details (such as card numbers).
The Ebbio lifetime license is generally available to the purchasing user across devices by using the “Restore purchases” feature through the associated store account. Because the Operator relies on the relevant store's systems to record and manage purchases, the Operator cannot guarantee recovery of your entitlement if the store's records are unavailable.
Refunds for purchases made in the App are governed by the refund policies and procedures of the store operator (Apple, Google, or another applicable store) through which the purchase was made. The Operator does not operate a separate refund process, and whether a refund is granted is determined by the relevant store operator. Please direct refund requests to the applicable store's support channel.
When using the App, you must not:
All intellectual property rights in the App, including its software, design, and trademarks, belong to the Operator or the applicable rights holders. These Terms grant you a limited, non-transferable right to use the App; they do not transfer any intellectual property rights to you.
You retain rights in the content of the Learning Data you create in the App.
The App is provided “as is.” The Operator disclaims all warranties, express or implied, including warranties of merchantability, fitness for a particular purpose, non-infringement, and freedom from interruption or defects.
The Operator does not guarantee any particular learning outcome, retention result, or other result from using the App. Review schedules generated by the FSRS algorithm are a statistical estimate, not a guarantee of individual results.
The Operator does not warrant the operation of your device, operating system, browser, network connection, or third-party services the App relies on, including Apple, Google, and RevenueCat.
Except where caused by the Operator's intentional misconduct or gross negligence, the Operator is not liable for any damages arising from your use or inability to use the App, including loss or corruption of Learning Data, lost profits, or indirect, special, or incidental damages.
Notwithstanding the foregoing, where the Operator is liable for damages, the Operator's total liability is limited to the total amount you paid the Operator for purchases relating to the App in the one year preceding the event giving rise to the claim, except where such limitation is not permitted under applicable mandatory law (including consumer-protection law).
Because Learning Data is stored primarily on your device, it may be lost if your device is lost, damaged, reset, or if the App is deleted, or if you have not made a backup. You are responsible for backing up or exporting your Learning Data as needed.
The Operator may change the App, or suspend or discontinue it, without prior notice to you. Except where caused by the Operator's intentional misconduct or gross negligence, the Operator is not liable for any resulting damages. If the App is discontinued, any copy of the App you have already downloaded and any Learning Data on your device will generally remain available to you, subject to the capabilities of your OS and store platform.
The Operator may revise these Terms when necessary. For material changes, the Operator will provide notice in the App or on this page, in advance or without undue delay. Revised Terms take effect when posted on this page or on a later effective date specified by the Operator. Your continued use of the App after a revision takes effect constitutes acceptance of the revised Terms.
These Terms are governed by the laws of Japan. Any dispute arising out of or in connection with the App or these Terms shall be subject to the exclusive jurisdiction of the district court having jurisdiction over the Operator's location as the court of first instance.
