How can Yoo help?
Tell us what happened and we'll help you get back to learning.
Email support@dayyoo.com →
No sound
Turn up media volume, disable Silent Mode, and try the word again. Tell us which language and word were silent if audio still does not play.
Widgets or reminders
Confirm Dayyoo has notification permission and that the widget is added from the iPhone widget gallery. Include a screenshot if its content is missing or outdated.
Purchase help
If you purchased Dayyoo Plus, manage renewal in iPhone Settings → your name → Subscriptions. Use Restore Purchases in Dayyoo if an active subscription is missing. For a missing Sparks purchase, tell us the product and purchase date; never send full payment details.
Account access and deletion
For a forgotten password, use Forgot password on the sign-in screen. Request a new link if the old one has expired or has already been used. Never send a reset link or verification code to support.
While signed in, open Settings → Manage account → Delete account → Continue, type DELETE, then choose Permanently delete account. An accepted request is processed in the background. Learning on this phone remains as guest data. Deleting an account or the app does not cancel an Apple subscription.
Help us solve it faster.
Please include what you tapped, what you expected, what appeared instead, your language mode, app version, and iPhone model. If useful, attach a screenshot or recording with personal information hidden. Never email passwords, verification codes, reset links, or full payment details.
