Android applicationId: com.kubosaburo.focusduck
iOS Bundle ID: com.kubosaburo.focusduck

1. Application of These Terms

These Terms apply between users of the App (“Users”) and Saburo Kubo, the developer and operator of FocusDuck (“the Developer”). By downloading or using the App, the User acknowledges and agrees to these Terms.

If you do not agree to these Terms, please discontinue use of the App.

2. About the App

The App gently supports everyday focus on Android and iOS through features such as a focus timer, focus records, a rest timer, focus sounds, the growth of a duck and pond, a breadcrumb exchange, and a creature book.

The App is intended to assist with study, work, reading, and other focused activities. It does not guarantee any specific result, grade, health outcome, productivity level, or habit formation.

3. Requirements and User Responsibilities

4. Data Stored on the Device

Focus duration, session counts, breadcrumbs, duck and pond growth, the creature book, decorations, and settings are generally stored on the User’s device. The App currently has no proprietary account registration system and no synchronization service operated on the Developer’s own servers.

Data may be lost or may not be recoverable if the App is deleted, the device is replaced, lost, damaged, or reset, or depending on the availability of operating-system backup. Users use the App with an understanding of this possibility.

For details about how data is handled, please review the FocusDuck Privacy Policy.

5. Advertising

The free version may display banner and interstitial ads served through Google AdMob (Google Mobile Ads). Ads are not displayed to Users with an active FocusDuck Plus entitlement.

Advertising and consent management are governed by the Privacy Policy and the applicable terms of Google’s services.

6. FocusDuck Plus

  1. FocusDuck Plus is a one-time, non-consumable purchase that removes ads and unlocks additional features. It is not a subscription.
  2. Purchases are processed through the store on each platform: Google Play on Android and the App Store on iOS. The price, currency, taxes, and payment terms that apply are shown in the relevant store interface at the time of purchase.
  3. The store processes the purchase and manages payment information. The Developer does not directly obtain credit card numbers or bank account details.
  4. A Plus entitlement purchased on Android is not automatically transferred to iOS. A Plus entitlement purchased on iOS is not automatically transferred to Android. Payment and entitlements are tied to each store account.
  5. Restore purchases works within the same platform and store: Google Play on Android and the App Store on iOS. Restoration does not cross operating systems.
  6. If a purchase is pending, Plus features will not be enabled until the relevant store confirms that the purchase is complete.
  7. If the store entitlement becomes invalid because of a refund, cancellation, fraud determination, or another reason, access to Plus features may end.

Refund eligibility and procedures are governed by the policies of the store used for the purchase and the applicable laws in the User’s place of residence. Android purchases follow Google Play policies. iOS purchases follow Apple / App Store policies. If a purchase does not appear in the App, first try restoring purchases in the same store and contact the Developer if the issue remains unresolved.

7. Prohibited Conduct

Users must not engage in any of the following conduct in connection with the App:

8. Intellectual Property

Copyrights, trademarks, and other intellectual property rights in the App, website, images of ducks, ponds, and creatures, text, audio, designs, software, and other content belong to the Developer or their respective lawful owners.

These Terms do not transfer or license any such rights to Users beyond the limited extent necessary for personal use of the App.

9. Changes and Temporary Suspension

The Developer may change the App or temporarily suspend its provision for reasonable reasons, including quality improvements, new features, maintenance, and compliance with laws or store policies.

Material changes will be announced when reasonably possible through the App, this website, the relevant store listing, or another appropriate method.

10. Disclaimer of Warranties

The Developer will make reasonable efforts to provide the App reliably, but does not guarantee that the App will operate correctly on every device or environment, remain free from errors or interruptions, or meet every User’s particular purpose.

Failures, specification changes, or service interruptions involving Google Play, the App Store, Google AdMob, or other third-party services may be outside the Developer’s direct control.

11. Limitation of Liability

Except in cases of intentional misconduct or gross negligence by the Developer, the Developer’s liability for loss arising from use or inability to use the App is limited to the extent permitted by applicable law.

No disclaimer or limitation in these Terms applies where it is prohibited by mandatory consumer-protection or other applicable law.

12. Changes to These Terms

The Developer may amend these Terms when reasonably necessary because of changes to the App, third-party services, laws, or store policies.

Revised Terms will be published on this page and will apply to use of the App after publication. Material changes affecting Users will be announced in advance when reasonably possible.

13. Governing Law and Dispute Resolution

These Terms are governed by the laws of Japan, without limiting any mandatory consumer protections that apply in the User’s place of residence.

If a dispute arises regarding the App or these Terms, the parties will first attempt to resolve it in good faith. If it remains unresolved, the court having jurisdiction under the laws of Japan will be the court of first instance.
