Last updated: 2026-09-02

The short version: no account needed, no personal data collected, no third-party advertising, no third-party analytics.

What we collect

We do not collect, store or transmit personal data to our servers. Lumi Bopomofo Pro: Zhuyin has no user accounts and no sign-in.

Where your data lives

Anything you create or set up in Lumi Bopomofo Pro: Zhuyin is stored on your device through Apple's standard on-device storage, and is removed with the app when you delete it.

Sharing and export

When you export or share something, it goes wherever you send it through the standard iOS share sheet. That step is yours, and nothing is sent anywhere until you choose a destination.

Third parties

The app contains no third-party advertising and no third-party analytics or tracking SDKs. We do not build a profile of you across apps or websites.

Children's privacy

Because the app collects no personal data from anyone, it collects none from children either. We never ask a child for a name, date of birth, contact details, photos or health data.

Your choices

Because no personal data leaves your device, there is no account here for us to delete. To remove local data, simply delete the app. For any privacy question or concern, please write to us.

Changes to this policy

If the app changes in a way that affects this policy, we will update this page and the date at the top.
