Terms of Service – NihongoDoya Android App

1. Acceptance of Terms

Welcome to the NihongoDoya Android application (“the App”), operated by NihongoDoya (https://nihongodoya.com). By downloading, installing, registering for, accessing, or using the NihongoDoya Android application and its connected cloud services, you acknowledge that you have read, understood, and agree to be bound by these Terms of Service. If you do not agree to these Terms, you must immediately refrain from installing, accessing, or using the application.

2. Description of Services

NihongoDoya is an independent educational and examination-preparation application built to assist students and candidates preparing for Japanese language evaluations and work qualification exams. The Android application provides users with:

• Japanese language study materials, vocabulary lists, kanji guides, and grammar explanations.
• JFT-Basic (Japan Foundation Test for Basic Japanese) practice questions and full-length Computer-Based Testing (CBT) mock simulations.
• Specified Skilled Worker (SSW) Skill Test practice examinations, including Nursing Care (Kaigo) and Food Service Industry evaluations.
• Cloud-synchronized test score tracking, progress review, and answer breakdown features powered by Google Sign-In.
• Free starter practice sets and voluntary rewarded advertisement-supported test unlocks.

All learning resources, interactive exercises, and practice mock tests provided in the Android application are made available free of monetary charge under our advertising-supported educational model.

3. Independent Platform Disclaimer

NihongoDoya is a strictly independent educational and self-study platform.

NihongoDoya is NOT affiliated with, associated with, authorized by, endorsed by, sponsored by, or in any way officially connected with:

• The Japan Foundation
• Japan Educational Exchanges and Services (JEES) or Japanese-Language Proficiency Test (JLPT) organizers
• Prometric Japan Co., Ltd. or official Prometric test centers
• The Immigration Services Agency of Japan (ISA) or the Ministry of Justice of Japan
• Specified Skilled Worker (SSW) evaluating bodies (including the Japan Association of Certified Care Workers / Silver Service Association, OTAFF, or other sector testing authorities)
• Any government ministry, testing council, or official certification board in Japan, Nepal, or elsewhere

All mock exam questions, practice tests, and study notes created or curated by NihongoDoya are designed strictly for educational training and self-assessment purposes. They are not official examination papers. Using NihongoDoya does not guarantee passing JFT-Basic, JLPT, or SSW examinations, nor does it guarantee visa acquisition, certificate issuance, or employment in Japan.

4. User Accounts and Google Sign-In

To record your mock test results, track performance history, and synchronize practice progress across app sessions, NihongoDoya utilizes Google Sign-In for secure authentication. By using an account within the App, you agree that:

• Account Security: You are responsible for maintaining the security of your Android device and the Google Account credentials used to sign in to the application.
• Personal Use: Account access is strictly personal and non-transferable. You must not sell, rent, lend, or share access to your authenticated account with others.
• Activity Responsibility: You are solely responsible for any practice sessions, test completions, or activity conducted through your authenticated account.
• Account Deletion: You have the right to request deletion of your account and associated cloud data at any time directly through the app settings or via our web portal at https://nihongodoya.com/delete-account.

5. Free Access to Educational Content

NihongoDoya is committed to lowering barriers to Japanese language education and examination readiness:

• Completely Free Application: The NihongoDoya Android app is provided free of monetary cost. There are no fees to install the app or practice with the study materials.
• No Purchases or Subscriptions: There are NO in-app purchases, paid packages, premium subscriptions, paid tiers, membership fees, vouchers, or activation codes.
• No Payment Details Collected: NihongoDoya never prompts users for credit card, debit card, digital wallet, or banking information. Any third-party claiming to sell paid access to NihongoDoya is unauthorized and fraudulent.
• Starter Mock Tests: Starter mock test sets (including JFT-Basic Sets 1, 2, and 3) are provided with direct, unrestricted free access without requiring advertisement viewing.

6. Rewarded Advertisements and Mock Test Unlocking

To sustain server infrastructure, question development, and ongoing app maintenance without charging users, NihongoDoya employs a voluntary rewarded advertisement system for extended mock tests:

• Voluntary Participation: Watching rewarded advertisements is entirely voluntary. Users choose whether and when to watch video advertisements to unlock specific practice tests.
• Two (2) Completed Advertisements Required: To unlock an ad-supported mock test (such as JFT-Basic Sets 4–90 or SSW Skill Tests), the user must watch two (2) complete rewarded video advertisements. Both video advertisements must be watched until full completion (triggering the AdMob reward verification). If an advertisement is closed early, skipped, or fails to complete, no unlock credit is awarded.
• Two-Hour (2-Hour) Temporary Unlock Window: Upon successfully watching two (2) complete rewarded ads, the selected mock test is unlocked for a temporary window of exactly two (2) hours (120 minutes) from the moment of completion.
• Automatic Relocking: Once the two-hour access window elapses, the mock test automatically returns to a locked state, and the ad completion counter resets to zero (0/2). To practice that mock test again, the user simply watches two (2) rewarded advertisements to initiate a fresh two-hour access window.
• Per-Test Scope: Unlocks apply strictly on a per-test basis to the specific set selected by the user. Unlocking one test does not unlock other mock tests across the application.
• Not a Purchase or Financial Contract: Watching rewarded advertisements does not constitute a purchase, payment, barter, or subscription. Users are not charged any money, and no monetary transaction or customer obligation is established.
• No Guarantee of Permanent Access: NihongoDoya does not guarantee or offer permanent, lifetime, or uninterrupted offline access to ad-supported mock tests. Access is strictly granted for the operational duration defined by the app’s unlocking rules.

7. Google AdMob and Third-Party Services

Advertisements inside the Android application are served and mediated by Google AdMob, an advertising network operated by Google LLC:

• Ad Inventory & Availability: NihongoDoya does not control advertisement fill rates, ad inventory, or auction delivery. The availability of rewarded video advertisements depends on Google AdMob, user geographic location, device settings, and current network conditions. Advertisement availability is not guaranteed. If no advertisement is available from Google AdMob at a particular time, mock test unlocking may be temporarily unavailable until ad inventory refreshes.
• Third-Party Ad Content: Advertisements shown within the app are delivered directly by Google AdMob and its advertising partners. NihongoDoya does not endorse, control, verify, or assume responsibility for any third-party products, services, claims, or applications promoted in advertisements. Interacting with advertisements or downloading third-party applications is done at your own discretion and risk.
• Ad Data Handling: Google AdMob may process device identifiers, ad interaction metrics, and IP addresses in accordance with Google’s privacy and advertising policies. For more details on data collection, please review our Privacy Policy and Google’s advertising disclosures.

8. Acceptable Use Policy

Users must use the NihongoDoya Android app strictly for personal, non-commercial educational study and exam preparation in compliance with all applicable laws. When using the application, you strictly agree NOT to:

• Attempt to bypass, tamper with, exploit, or defeat the application’s advertisement delivery, reward verification callbacks, or test unlocking timers.
• Use automated scripts, bots, click farms, emulators, debuggers, memory interceptors, or modified APKs to simulate ad views or circumvent practice test access conditions.
• Scrape, crawl, harvest, or bulk-export exam questions, audio recordings, answer keys, or study notes from the application.
• Decompile, reverse-engineer, disassemble, or attempt to derive the source code or backend APIs of the application.
• Interfere with, overburden, compromise, or disrupt the operation of NihongoDoya backend services, Firebase databases, or server infrastructure.
• Resell, redistribute, or commercially exploit any content, mock test simulations, or access to the application.

9. Intellectual Property

All software code, graphic interfaces, icons, question databases, answer explanations, audio recordings, furigana annotations, and educational text contained within the NihongoDoya Android application are the proprietary intellectual property of NihongoDoya, protected by copyright, trademark, and other applicable intellectual property laws.

Limited License: Subject to your compliance with these Terms, NihongoDoya grants you a personal, revocable, non-exclusive, non-transferable, and royalty-free license to access and practice with the application on your Android device solely for your personal, non-commercial educational preparation.

Restrictions: No part of the application, including mock exam question banks, audio files, or study guides, may be reproduced, republished, redistributed, broadcast, sold, or framed in any form without prior explicit written permission from NihongoDoya.

10. Service Availability

We make reasonable efforts to ensure the App, cloud progress saving, and study materials remain accessible and functional. However, the application and its online services are provided on an “as is” and “as available” basis without warranties of any kind.

We do not guarantee that the application will be uninterrupted, error-free, immune to technical glitches, or available at all times. Service interruptions may occur due to regular server maintenance, software updates, telecommunication failures, cloud hosting disruptions, or third-party ad server outages. NihongoDoya reserves the right to modify, update, or discontinue features of the application at any time without prior liability.

11. Examination Information Disclaimer

Official examination guidelines, test dates, registration schedules, fees, computer-based testing (CBT) interfaces, passing score thresholds, and Japanese immigration requirements are established independently by official test administrators (such as The Japan Foundation, Prometric, and the Immigration Services Agency of Japan).

While NihongoDoya continuously updates its study notes and question banks to reflect realistic examination structures, we do not warrant that all practice questions will correspond identically to real examination content or that official test formats will not change. Mock test results within the app serve solely as self-evaluation indicators and do not certify exam readiness or assure any specific score on official tests. Learners are solely responsible for verifying official examination policies, deadlines, and seat bookings through authorized examination websites.

12. Limitation of Liability

To the fullest extent permitted by applicable law, NihongoDoya, its developers, operators, contributors, and affiliates shall not be liable for any direct, indirect, incidental, special, consequential, or punitive damages arising out of or related to:

• Your use of or inability to use the Android application or its educational resources.
• Any examination results, official test failure, loss of examination fees paid to test providers, or delay in educational or career objectives.
• Unavailability of rewarded advertisements or temporary inability to unlock mock tests.
• Any loss of progress, data corruption, device malfunction, or network-related expenses incurred while using the App.

Because the NihongoDoya Android application is offered free of charge without any monetary payment, in no event shall NihongoDoya’s aggregate liability exceed zero (USD $0.00 / NPR 0).

13. Suspension and Account Termination

NihongoDoya reserves the right to immediately suspend, restrict, or terminate access to the application or associated cloud data for any user who engages in:

• Fraudulent activity, ad manipulation, or automated abuse of the rewarded unlocking system.
• Unauthorized copying, scraping, extraction, or redistribution of proprietary question banks.
• Security attacks, reverse engineering, or intentional disruption of backend databases or APIs.
• Any violation of these Terms of Service or applicable local laws.

Legitimate students and learners utilizing the application in good faith for personal Japanese study will not have their access arbitrarily suspended or terminated.

14. Changes to Terms

We may revise and update these Terms of Service from time to time to reflect changes in app functionality, ad network requirements, or legal standards. Whenever updates occur, the revised document will be posted on this page (https://nihongodoya.com/app/terms) with a refreshed “Last Updated” date at the top of the page. Your continued use of the NihongoDoya Android application after revised Terms are published constitutes your acceptance of the updated Terms.

15. Governing Law

These Terms of Service and any dispute, claim, or controversy arising out of or related to the NihongoDoya Android application shall be governed by, interpreted, and construed in accordance with the laws of Nepal, without regard to conflict of law principles. Any legal action or proceeding arising under these Terms shall be instituted exclusively in the competent courts situated in Nepal.
