App Onomatope オノマトペ · version 1.0 · last updated: 4 September 2026

Onomatope オノマトペ teaches Japanese onomatopoeia: which of four similar sounds a sentence asks for, and what 濁点 does to a word. The old line said how high to pitch it. All of the learning happens on your device, with no internet.

In short: no account, no analytics, no advertising and no server. The app makes no network request of any kind except to the App Store, for the purchase itself.

Your account

There isn't one. Onomatope does not ask you to register, sign in or provide an email address, and it has no way to identify you.

Where your learning data goes

Nowhere. Your mastery of each item, your answer history and your review schedule are stored on your device and never leave it.

Tracking and advertising

None. There is no analytics SDK, no advertising SDK, no crash reporter and no tracking identifier of any kind in the app.

Purchases

The one-off Premium purchase is handled entirely by Apple. Onomatope never sees your payment details; it only asks StoreKit whether a purchase exists.

Children

Onomatope is rated 4+ and collects no data from anyone, of any age.

Changes

If this policy ever changes, the updated date at the top changes with it. This page's address carries the app version, so older releases always point at the document that actually described them.
