Privacy Policy

Last updated: September 7, 2026

Krengbible ("the app," "we," "us") is a bilingual Korean/English Bible reading app. This page explains what information the app collects, how it is used, who can see it, and how to reach us.

What we collect

If you create an account, we collect:

This is stored in Firebase (Firestore and Storage, operated by Google) under your account. It is private to you and we do not share it with anyone. The one exception is a reading group you choose to join, where other members see your profile, a summary of your reading, and any note you share to that group.

If you do not create an account, the app still keeps your reading progress, highlights, and settings — but only on your device, never sent anywhere.

Usage analytics

The app uses Firebase Analytics (Google) to understand how it is used, so we can improve it. This includes which screens are opened, which features are used, and reading activity — which book and chapter was read, in which translation and language, and whether that translation was the primary or the secondary one on screen. Search terms typed into the app's search are also recorded.

This is first-party analytics about app usage only. It is not used to track you across other companies' apps or websites, no advertising identifier is collected, and analytics data is not linked to your name or email address. Analytics data may be exported to Google BigQuery inside the same project so we can summarise it; it stays under our own Google account and goes nowhere else.

What we don't do:

Third-party services

The app relies on a small number of services to function:

AI-generated content

Some devotional reflections and section-heading translations are generated by an AI service from Bible text alone. No personal or account information is sent to it, and nothing you write is used to train any model.

Data retention and deletion

Your synced data is kept as long as your account exists. You can permanently delete your account and its synced data at any time from within the app: Settings → Delete Account. If you would rather we did it for you, email the address below.

Deleting your account removes your synced highlights, saved verses, folders, notes, reading progress, and journal entries. Anything you shared into a reading group stays with that group, as a message in a conversation does, so delete those and leave your groups first if you want them gone too.

Children's privacy

The app is not directed at children under 13, and we do not knowingly collect personal information from children under 13.

Changes to this policy

If this policy changes, the "Last updated" date above will change with it.
