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.
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.
