Effective 8 November 2026 · Version 1.0

Privacy, simply.

Ninja Kana is provided by April Wong. Version 1.0 works without a player account, advertising, or in-app analytics.

Your progress

Practice progress, scores, selected katana, and sound preferences are stored on your device. They are not sent to us. There is no Ninja Kana cloud sync. Your operating system may include app data in device backups under your own backup settings.

Your voice

If you choose spoken play, the app uses the microphone and Apple’s on-device Japanese speech recognition. Audio and recognition results are used during the current reading. The app does not save voice recordings or send them to our servers. If on-device recognition is unavailable, you can use tap choices; the iOS app does not silently switch to cloud recognition.

Japanese recognition models may need an initial download handled by Apple. Permission can be changed in device Settings. The spoken guide uses recordings generated with ElevenLabs and bundled with the app; no player text or voice is sent to ElevenLabs.

What we collect

The app does not transmit your name, email address, location, identifiers, progress, or voice recordings to us. It includes no advertising or third-party analytics SDK. Its illustrations, music, fonts, and stroke diagrams are bundled with the app.

Optional purchases

Apple processes the optional one-time unlock through the App Store. The app uses StoreKit to verify access and restore purchases. We do not receive your payment card details or operate a separate purchase-account server. Apple processes purchase information under its own privacy policy.

If you email hello@anonagency.xyz, we receive your email address and the information you choose to send.

Removing your data
