Privacy Policy

Kaigo Prep (Android) · package com.kaigoprep.app · effective 26 October 2026

Kaigo Prep (“the app”) is a study app for the Specified Skilled Worker (SSW) Nursing Care Skills and Nursing Care Japanese Language evaluation tests, published by Abdul Hakeem Mehmood Hussain (“we”). This policy explains what information the app handles and why.

1. No account, no personal data required

The app has no sign-in and never asks for your name, email address or phone number. Your study progress (answers, bookmarks, mock-exam results, flashcard schedule, unlocks and settings) is stored only on your device and is never uploaded to our servers. Uninstalling the app, or using “Reset progress” in the app, deletes it. We cannot see or recover it.

2. When the app goes online

The app works offline. It connects to the internet only to:

• check for corrected questions (a content file from our server; on Wi-Fi only unless you allow mobile data in Settings);
• check a school or training-centre code you enter, against a signed list the app downloads. The code you type is not sent anywhere;
• make Google Play purchases;
• show ads in the free version, and send crash reports and usage counts (sections 3 and 4).

3. Advertising (Google AdMob)

The free version shows ads served by Google AdMob: banners, full-screen ads between practice sets and after mock results, and optional rewarded videos that unlock extra content for 24 hours. Google may collect and process your device’s advertising identifier, IP address, coarse location derived from it, and app-usage signals to serve and measure ads, as described in Google’s advertising policies and the Google Privacy Policy. Where the law requires it (for example in the EEA and UK), you are asked for consent first. You can reset or delete your advertising ID and opt out of personalised ads in Android Settings → Google → Ads. Buying the Kaigo Pack stops all ads.

4. Analytics and crash reporting (Firebase)

We use Google Firebase Crashlytics and Firebase Analytics to fix crashes and to understand which features are used. They receive anonymous events (a session started, a question was answered or reported – by its question number, a mock exam was completed and its score, the paywall was viewed, a purchase was completed), device model, OS and app version, and for crashes a stack trace. Analytics is configured not to collect the advertising ID. These services receive no name, contact details or anything you type. See the Firebase privacy information.

5. In-app purchase (Google Play Billing)

The optional one-time Kaigo Pack is processed entirely by Google Play. We do not receive or store your payment details; the app only receives confirmation that the pack was bought.

6. Permissions

The app requests Internet and network-state access (for the uses in section 2) and Google Play billing. The Google ads and Firebase libraries add the advertising-ID and Android ad-services permissions, install-referrer access and a wake lock for background uploads. The app does not request location, camera, microphone, contacts or storage permissions.

7. Children

The app is meant for adults preparing to work in Japan and is not directed at children under 13. We do not knowingly collect personal information from children.

8. Content source and affiliation

Questions are written from the official study text published by Japan’s Ministry of Health, Labour and Welfare. Kaigo Prep is an independent study app. It is not affiliated with or endorsed by the Ministry of Health, Labour and Welfare, Prometric, or any test organizer, and its questions are not the actual test questions. Japanese audio uses the HTS voice “Mei” (Nagoya Institute of Technology, CC BY 3.0).

9. Changes and contact

We may update this policy; the effective date above will change accordingly. Questions: abdulhakeemahmood@gmail.com.
