How can we help?
Get support for lessons, progress, audio, Practice Chat, Word Collector, privacy, or accessibility.
Email Koko Support
Include your device or browser, operating-system version, Koko version, selected language, and the screen where the issue occurred. Please do not include passwords, identity documents, or sensitive photos.
Quick checks
- Audio: Turn up your media volume and check whether sound is going to headphones or a Bluetooth speaker. Tap a speaker button to replay. Words without a speaker may not have a recording.
- Camera or microphone: In iOS, open Settings → Koko. On the web, review permissions for hellokoko.app in your browser.
- Practice Chat or Word Collector: Confirm you have an internet connection. These tools send only the text or selected image you choose when you submit a request.
- Progress: Guest learning progress stays on your device or browser. In iOS Settings or on the web, sign in with Google or Apple to back up lessons, vocabulary, XP, and streaks and sync them across supported devices and browsers.
Still having trouble with audio?
Try a second phrase to see whether the problem affects one recording or every recording. If Koko shows an audio message, use Try again. Please do not delete the app to troubleshoot: guest progress is saved on your device.
When you email us, include the language, lesson or story title, the word you tapped, and whether you heard nothing, the wrong word, or distorted sound. Your iPhone model, iOS version, Koko version, and whether you were using headphones also help. A screenshot of the lesson is useful. Please leave private messages and personal photos out of any recording you send.
Privacy requests
On iOS, use Delete Account & All Data in Koko Settings to remove local learning data and either your optional cloud account or the anonymous identity used by online features. On the web, signed-in learners can use Delete account and data in Profile. Neither action deletes your Apple or Google account. For other questions about your information or deletion, email [email protected] with “Koko Privacy Request” in the subject. Read the Privacy Policy for details.
Report a curriculum issue
If a translation, transliteration, audio clip, or lesson explanation looks wrong, use the flag button on the lesson or story. If you email instead, include the language, unit, lesson or story, and the exact phrase. That context helps us investigate without collecting unrelated data.
