Support — Kantu

The picture was not analyzed

Confirm the device has an internet connection.
Try a well-lit picture with the main objects in focus.
Avoid very large panoramas or pictures that are still downloading from cloud storage.
Wait a moment and retry if the analysis service is busy. Failed requests should not use your picture allowance.

Change the learning language

Open the language selector and choose another language. Kantu translates the existing grounded names and sentences without analyzing the picture again. Changing language does not use another picture.

Pronunciation does not play

Turn up media volume.
Check that the device is not connected to an inactive Bluetooth output.
Confirm the device is online, then try again after a few seconds.

Saved words and collections

Saved dictionary words are kept on the device. Pictures saved to a personal collection are stored privately with their labels so they can be opened on your other devices. You can delete an individual collection picture from the Collections screen.

Plans, purchases, and restore

The free plan includes 5 successful picture analyses each month. Basic and Premium increase that monthly allowance. Current prices and billing periods are shown inside the app before purchase.

If a paid plan is missing, open the plans screen and choose Restore purchases. Confirm that the device is signed into the same Apple or Google account used for the purchase. For a billing or refund request, use Apple or Google’s purchase-support process.

Cancel a subscription

Subscriptions are managed by Apple or Google. Cancel from your App Store or Google Play subscriptions settings. Deleting Kantu or deleting your Kantu account does not automatically cancel an active store subscription.

Delete your account

In Kantu, open Account and choose Delete account. This removes your account profile, cloud collections, usage history, subscription mirror, synchronized learning progress, and Kantu data cleared by the app from that device.

If you no longer have the app, use the web account-deletion process.

Report an incorrect label

Email contacto@dev-lab.cl with the term Kantu showed, the word you expected, your selected languages, and—only if you are comfortable sharing it—the original picture. Remove private or sensitive information before attaching a picture.
