Support

A person reads every email, usually within two working days.

Email hello@yenkai.app. Tell us what you were trying to do, what happened instead, and which phone or browser you use. A screenshot helps.

Signing in

Yenkai signs you in with a 6-digit code sent to your email, so there's no password to forget. If the code doesn't arrive, check your spam folder, then ask for a new one.

Inviting people

Open a book, go to Members and invite someone by email. They get a link that opens the book on iPhone, Android or the web.

Saving a photo

Tap any photo to open it, then use Share to save the original at full quality.

Plus

Plus is billed by the App Store, Google Play or Lemon Squeezy, depending on where you bought it. To cancel, manage the subscription in the same place. To restore Plus on a new phone, sign in with the same email and tap Restore purchases.

Deleting your account

Go to Profile in the app and choose Delete account. See the Privacy Policy for what that removes.
