Terms of Use for Echo
Last updated: 24 October 2026
The app
Echo is an Estonian practice app. You can translate, repeat, listen, and run short trip-style drills. Num Num OU (operating as 7x network) publishes it. Speech recognition uses your device. Progress stays on the device.
Microphone
The microphone is used only while you practice. Echo does not upload your voice. The operating system’s speech service has its own terms.
Not a language certificate
Scores and corrections are practice feedback. They are not an official assessment of Estonian and they do not guarantee fluency.
Disclaimer
Echo is provided as-is.
