You can use Rondo without an account. Your wordbooks, words and learning history are saved on your phone.

What we store

Only if you turn on Back up & Sync by signing in with Apple or Google, we store: the account ID that Apple or Google gives us, your email address if they share it, and a copy of your wordbooks, words, learning history and settings.

How we use it

We use this data only to back up your words and keep them in sync across your devices. We do not sell it, show ads, or use advertising or analytics trackers.

What stays on your phone

Pronunciation uses your phone's text-to-speech. Reading words from a photo is done on your phone with Google ML Kit, and the photo is not sent to us. Reminders are scheduled on your phone.

Where it is stored

Backed-up data is stored on Google Cloud servers in Seoul, South Korea, and is sent over encrypted connections.

Keeping and deleting your data

We keep your backup until you delete your account. When you delete it, your account and backup are removed from our server right away. Words on your phone are not affected. Delete account
