Privacy policy

Last updated 10 November 2026

This policy covers the Daruma app and this website. Daruma is run from Ukraine. To ask anything about your privacy, write to jlptdarumaapp@gmail.com.

In short

The app collects no personal data. There is no account to create, and the app keeps your progress on your device and sends nothing to us or to anyone else. This website sets no cookies and has no analytics. The only personal data Daruma receives is what you send us by email.

The app

• There is no account and no sign-in.
• Your answers, levels, saved sets and settings, and a random number that tells this install apart, are stored only on your device, in the app’s own storage. We can’t see them. Settings, then Reset progress, deletes your answers and levels. Deleting the app deletes everything on the device.
• If your device backs up its apps (iCloud or Google backup), your progress may be included in that backup, which Apple or Google keep under your account. That copy stays until the backup is replaced or deleted, and Android may restore it if you install Daruma again.
• The app has no analytics, advertising, tracking or crash-reporting tools, and it doesn’t ask for your contacts, location, camera, microphone or photos.
• The app doesn’t connect to the internet by itself. Some screens have links, for example to a kanji’s page on Jisho or Wiktionary, or to a source’s website. A link opens in your browser, and that website’s own privacy policy applies.
• Apple or Google handle downloading Daruma from the App Store or Google Play, under their own privacy policies. They show us totals such as the number of downloads and, if you chose in your device’s settings to share analytics or crash data with developers, summary usage statistics and crash reports. None of these tell us who you are.

This website

• It sets no cookies, has no analytics or advertising, and stores nothing in your browser. It loads no fonts, scripts or images from other websites.
• It is hosted on Google’s Firebase Hosting. To deliver the pages, Google’s servers receive the usual details of each request, such as your IP address, your browser and the page asked for, and Google may keep them in its logs for a limited time (see Firebase privacy). We don’t use them to identify anyone.

Email

If you write to jlptdarumaapp@gmail.com, we receive your email address and what you write. We use it only to answer you and to fix what you report, and we don’t share it. We keep a message only until your question is answered or the problem you reported is fixed, and you can ask us to delete it sooner. The mailbox is a Gmail account, so Google stores the messages.

Children

The app collects no personal data from anyone, children included.

Your rights

Because the app collects no personal data, there is normally nothing for us to show you, correct or delete: your progress is on your device. To see or delete the emails you sent us, write to jlptdarumaapp@gmail.com. You can also complain to the data protection authority where you live.

Changes

If Daruma ever needs to collect data, for example to sync your progress between devices, this policy will change before that happens and say exactly what is collected and why. The date at the top shows the last change.
