We're glad you're here. Here's how to get help.
KnockKnock is a prayer and emotional check-in app. If you have a question, a problem, or feedback, email us and we'll do our best to help.
Yes. KnockKnock has no accounts, and using it doesn't require your name, email, or location. Your check-ins are stored on your device. If you email us or send in-app feedback, we'll have whatever you choose to include (used only to reply to you). See our Privacy Policy for full details.
Everything the app stores lives on your device. Use Delete all my data in Settings → Security & data to erase it, or simply delete the app - both remove your check-ins and saved verses.
Check your internet connection and try again in a moment. There is also a daily usage limit to keep the app sustainable; if you hit it, please try again the next day.
When you chat, what you type (plus the emotion and context you chose) is sent securely to our AI provider to generate a caring, faith-informed response. It's meant for reflection and encouragement.
We'd love to hear it. Use the in-app Feedback form (Settings → Feedback), or email yehsunkang@gmail.com with what happened (and your device model if it's a bug).
KnockKnock is not a therapist, counselor, or medical service. If you are struggling or thinking about harming yourself, please reach out to a trusted adult, or contact the 988 Suicide & Crisis Lifeline — call or text 988 in the U.S. You are not alone, and you matter.
