Frequently asked questions

How do I create an account?

You can sign up using your Apple or Google account. Open the app and tap "Sign in" to get started.

How do I delete my account?

You can request account deletion by emailing us at matsumoto_taiga@outlook.jp. We'll delete your account and all associated data within 30 days.

How do I save words?

While listening to a lesson, tap any word in the transcript. It will be saved to your personal word bank with its meaning and context.

How do review reminders work?

Kikeru uses FSRS, a spaced repetition algorithm, to schedule reviews at the optimal time. Words you find difficult appear more often, while easier words are spaced out further.

How do I turn off notifications?

Go to your device's Settings, find Kikeru, and toggle off notifications. You can also manage notification preferences within the app.

Can I use Kikeru offline?

Lessons need to be downloaded while online, but once downloaded, you can listen and review your saved words offline.
