Terms of Use

Kudoku for Android

Effective September 24, 2026. Kudoku is developed by Gentleflow. By using Kudoku, you agree to these terms. Contact: gentleflowoverseas@gmail.com.

Use of the app

You may use Kudoku for personal puzzle play. The app, artwork and puzzle collection belong to Gentleflow or their respective licensors. Do not redistribute them without permission. Open-source components remain subject to their own licenses.

Gameplay and progress

Kudoku provides logic puzzles for recreation and makes no promise of medical, educational or cognitive outcomes. Progress is stored only on this device. Clearing app storage or uninstalling removes local progress. The app does not provide cloud saves or cross-device progress synchronization.

Optional Premium

Premium is optional. Available monthly, yearly and lifetime products, local prices and billing terms are shown before purchase and confirmed by Google Play. Monthly and yearly plans renew automatically unless cancelled. The lifetime option is a single purchase for Premium access with no recurring subscription payment. Premium does not change Hell mode’s lives, scoring or restrictions on assists.

Trials and renewal

Only eligible customers receive a free trial. If a trial is offered, its duration and the price and billing period that follow are shown before purchase. Cancel in Google Play before the trial ends to avoid the first subscription charge. After cancellation, access normally continues until the end of the paid period. Google Play’s terms and the details on its purchase confirmation apply.

Manage, restore and refunds

Manage or cancel in Google Play → Payments & subscriptions → Subscriptions → Kudoku, or use Manage subscription in the app. Uninstalling does not cancel a subscription. Use Restore purchases with the Google Play account used for purchase. Purchases on other stores do not automatically transfer to this Android version. Refund requests are handled under Google Play’s refund policies and applicable consumer rights: https://support.google.com/googleplay/answer/2479637.

Availability and your rights

We may update the app and its features. We aim to provide reliable gameplay but do not guarantee uninterrupted availability or that every puzzle suits every player. Nothing in these terms excludes rights or remedies that cannot lawfully be excluded under the law applicable to you.
