Juri Kana — Privacy Policy
Last updated: 18th October 2026
Juri Kana collects no personal data. The app has no accounts, no sign-in, no analytics and no advertising, and it makes no network connection of any kind. Everything you do in it stays on your device.
This policy covers the Juri Kana mobile app only. Purchases of workbooks and other products from learnwithjuri.com are covered by the separate privacy policy on that site.
What we collect
Nothing. We do not collect, receive or have access to any information about you or your use of the app.
The app has no account system, so you never give us a name, email address or any other detail. It contains no analytics, crash reporting, advertising or tracking software of any kind. It makes no network requests, so there is no server for your information to be sent to, and we could not obtain it even if we wanted to.
This is why the app's App Store privacy label states that no data is collected.
What the app stores on your device
The app saves your learning progress locally, using your device's own storage, so that it is still there when you come back. That includes:
- which characters you have started and how well you know each one, with the dates your reviews are due
- your starred favourites
- your daily streak and the date you last studied
- your settings, such as whether romaji is hidden and whether sounds play automatically
None of this leaves your device. It is not backed up to us, synced between your devices, or visible to anyone else. You can clear all of it at any time from Settings, using Reset progress, and deleting the app removes it entirely.
Third parties
No third party receives any information about you through this app. There are no advertising networks, analytics providers or tracking tools in it.
The app does include some third-party content, all of which ships inside the app and runs entirely on your device:
- Pronunciation audio. The clips were synthesised in advance using a text-to-speech service and reviewed by a native Japanese speaker. They are ordinary audio files bundled with the app, so no speech service is contacted while you use it and nothing you do is sent anywhere to be spoken.
- Stroke-order data. Character stroke data comes from KanjiVG by Ulrich Apel, used under the Creative Commons Attribution-ShareAlike 3.0 licence.
- Open-source software libraries, used to store your settings and play audio. These operate locally and transmit nothing.
Younger learners
The app collects no personal information from anyone, children included, so there is nothing we could knowingly or unknowingly gather from a child using it.
It also contains no advertising, no in-app messaging or chat, no user-generated content, no social features and no links that open outside the app.
Your rights
Because we hold no personal data about you, there is nothing for us to give you a copy of, correct or delete. The learning data the app creates is on your device and under your control: you can clear it from Settings or by deleting the app.
If a future version of the app ever did collect anything, we would update this policy and the App Store privacy label before that version was released.
Changes to this policy
If this policy changes, the revised version will be published on this page with a new "Last updated" date.
