Question 1

What is Dan Hana?

Accepted Answer

Dan Hana is a minimalist habit app. Pick one promise each morning, check it off in ten seconds at night. A weekly AI letter reflects your quiet progress.

Question 2

Is Dan Hana free?

Accepted Answer

Yes. Every feature in v1.2 — daily promises, statistics, AI letters, reminders — is free. We will announce 30 days in advance if any premium feature is introduced.

Question 3

Which devices does Dan Hana support?

Accepted Answer

iOS 15.1 or later and Android 8.0 or later. The app is fully translated in Korean and English; system language is detected automatically on first launch.

Question 4

I forgot my password. How do I reset it?

Accepted Answer

On the sign-in screen tap “Forgot password,” enter your registered email, and follow the link we send. Check the spam folder if the email seems missing.

Question 5

Where is my data stored?

Accepted Answer

All records are encrypted at rest in Supabase (AWS Seoul / ap-northeast-2). Weekly AI letters are generated through the OpenAI API and inputs are deleted within 30 days.

Question 6

I missed a day. Does my streak reset?

Accepted Answer

Yes — choosing “Missed” resets your streak to zero. That is okay. Tomorrow simply restarts at day one. Dan Hana favors a gentle day over a perfect one.

Question 7

How do I change reminder times?

Accepted Answer

Open Settings → Notification time and adjust the morning and evening times independently. Each must be at least four hours apart.

Question 8

I am not getting notifications.

Accepted Answer

On iOS confirm Settings → Dan Hana → Allow Notifications is on. On Android also check the notification channel. If the issue persists, email us with your device model.

Question 9

How do I delete my account?

Accepted Answer

Open Settings → Account → Delete account. All records are erased immediately. Full details on the Account & Data Deletion page.

Question 10

Can I suggest a feature?

Accepted Answer

Absolutely. Send a one-line email to danhana.official@gmail.com — every message is read by the operator personally.
