KippuKIPPU / PRIVACY
Privacy policy
Effective November 5, 2026
Study records stay in the app’s local storage. Ads in the free plan, Google Play purchases and text-to-speech involve third-party services.
Who this policy covers
Kippu is operated by shameowstudio (言葉咲堂 Kotoba Learning). This policy covers the current Kippu Android app, package com.shameowstudio.kippu.jlpt, its Google Play testing releases, and these Kippu web pages. An iOS edition is planned but has not been released. Its platform-specific data practices and purchasing terms will be described before release.
Study data on your device
Your answers, study progress, practice results, settings, exam date and reminder choices are stored in the app’s local storage. Kippu does not operate an account system or send these learning records to its own server. Android backup may copy app data to your Google backup according to your device settings. There is no Kippu cloud sync between devices or operating systems.
Google Play purchases
Google Play processes subscriptions and one-time purchases under Google’s terms and privacy policy. Kippu receives information needed to unlock, restore and acknowledge Pro, such as the product ID, purchase token, purchase time and purchase state. Kippu does not receive your card number or bank details. This version verifies purchase state through Google Play on the device; Kippu does not send purchase tokens to an independent Kippu server.
Advertising in the free plan
The free plan uses Google AdMob and Google’s User Messaging Platform for advertising and consent choices. The Google Mobile Ads SDK collects and shares IP addresses (which may indicate approximate location), app and ad interactions, diagnostic and performance information, and device or account identifiers such as the advertising ID and app set ID. Google processes this information for advertising, analytics and fraud prevention. Google Mobile Ads SDK transmissions are encrypted using TLS. Kippu does not request precise location permission. Active Pro users do not generate ad requests from Kippu.
Your advertising choices
Where applicable, Kippu presents Google’s consent form before requesting ads. You can reopen available privacy choices from the app’s settings. Your region, age and Google consent eligibility affect which choices are shown. Declining personalized advertising does not necessarily stop all advertising or all processing required for limited ads and fraud prevention. Android also lets you reset or delete your advertising ID.
Speech, music and reminders
Listening uses the Japanese text-to-speech engine installed on your device. The engine provider may process the text on the device or through its network service, depending on the voice and settings you choose. Use an offline voice if you want speech to work without a network. Kippu does not record your voice or request microphone permission. Music and button sounds are bundled audio files. Reminder notifications are scheduled on the device; they are not sent by a Kippu push server. Notifications require the permission offered by your Android version.
This website and support email
These Kippu pages do not include advertising, an analytics tag or a contact form. Our hosting provider, Xserver, may process technical access records such as IP address, requested URL and access time to deliver and secure the website. If you email support, we receive your email address and the information you choose to send. We use those messages to answer the request and investigate the reported issue. Please do not send passwords, full card details or unrelated sensitive information. Google and our hosting/email providers process data under their own policies.
Retention, deletion and your rights
Clear Kippu’s app storage in Android settings or uninstall the app to delete its local study data. Restoring an Android backup can restore saved data; manage or remove backups in your Google/device settings if needed. Clearing app data or uninstalling does not cancel a Google Play subscription or erase Google’s purchase records. Manage those through Google Play. For support messages or privacy requests relating to data we hold, email the contact below. We keep correspondence only as needed to handle the request and meet applicable obligations. Third-party records follow the provider’s retention and deletion processes. Depending on your region, you may have rights to access, correct, delete or restrict processing of personal data, or complain to your local privacy authority.
Learners aged 13 and over
Kippu is intended for learners aged 13 and over and is not directed at children under 13. If you believe a child has sent personal data to us, please contact support so we can investigate and address it. A parent or guardian should help a minor understand purchases and privacy choices where required.
Changes and contact
We update this page when Kippu’s data practices change. The effective date is shown above. Privacy questions and requests can be sent to shameow-support@shameoww.com. We do not sell your study records or use support correspondence to send marketing messages.
