Quick troubleshooting
Check microphone access
Open iOS Settings, find Koko, and make sure Microphone access is enabled. Then close and reopen Koko.
Restart the App
Close Koko from the iOS app switcher and open it again. If the issue continues, restart your iPhone.
Check storage and updates
Make sure your iPhone has available storage and install the latest Koko and iOS updates compatible with your device.
Reinstall carefully
Reinstalling may remove locally stored conversations and progress. Because Koko does not receive that data, support cannot restore it.
Frequently asked questions
Does Koko need an internet connection?
Koko's core listening, speaking, conversation, and progress features are designed to run locally on your iPhone. App Store downloads and updates still require Apple's services and an internet connection.
Does Koko upload my voice or conversations?
No. The App is designed so your microphone audio, transcripts, conversations, generated responses, and learning progress remain on your device. See the Privacy Policy for details.
Why did Koko give an incorrect response?
Koko uses an on-device language model. Language models can make mistakes, invent information, mistranslate, or produce awkward phrasing. Treat responses as practice material rather than verified facts or professional advice. See the Terms of Use for the full AI output notice.
Can support recover my progress?
No. Koko does not maintain a cloud account or receive your local progress, so Prism Labs cannot view or restore it. Protect your device and consider your iOS backup settings before deleting the App or resetting your iPhone.
How do I delete my Koko data?
Koko does not create an account on our servers. To remove the App and its local data from an iPhone, choose "Delete App" in iOS rather than "Offload App," which may preserve documents and data. Apple controls any device backups through your Apple and iCloud settings.
How do I manage or cancel a purchase?
Apple manages App Store purchases, subscriptions, and refunds. Open iOS Settings, select your Apple Account, and choose Subscriptions, or contact Apple Support for App Store billing assistance.
Which languages does Koko support?
Koko supports English, Spanish, French, Polish, German, and Japanese. Available features may vary by language and App version.
