Last updated: 2026-01-05

Overview

Japan JLPT N5 is an educational app that helps users study Japanese at the JLPT N5 level, including vocabulary, grammar, and kanji. We respect your privacy and are committed to protecting it.

Key promise: The app does not ask you to provide personal information such as your name, phone number, email address, or home address, and it does not collect personal data to identify users.

Information the app uses

1) Learning content (questions/lessons)

The app’s learning content (vocabulary, grammar, kanji, and quiz questions) is stored in an online database so the app can download and display it to users.

2) Advertising

The app displays ads. Advertising providers may automatically collect certain technical information (for example: advertising identifiers, device information, and ad performance data) to deliver and measure ads. This collection is performed by third parties (ad networks) under their own privacy policies.

3) Daily quiz limit & “watch an ad to continue”

The app allows users to take up to 10 quiz sessions per day. When the limit is reached, the app shows a message and may allow users to watch an ad to continue taking quizzes.

Information we do NOT collect

If we add features in the future that require data collection, we will update this policy and clearly inform users.

Third-party services

The app may use third-party services to provide learning content and advertising. These third parties may collect data according to their own privacy policies.

Content data service
Firebase (Google) – stores and delivers learning content for the app to download and display.
Advertising
Ad network (for example, Google AdMob if you use it) – serves and measures ads.

Please review the privacy policies of the relevant third-party providers (Google/Firebase/AdMob) for more details.

Security

We use reasonable measures to protect the app configuration and services. However, no method of transmission over the Internet or electronic storage is 100% secure.

Children’s privacy

This is an educational app. The app is not intended to collect personal information from children. If you are a parent/guardian and believe a child has provided personal information, please contact us so we can assist.

Changes to this policy

We may update this Privacy Policy from time to time. Any changes will be posted on this page with an updated “Last updated” date.
