Privacy Policy

Scope

This policy applies to izb.app and the Plum Blossom Numerology, Four Pillars, Zi Wei Dou Shu and Qiyao products under the AIZHANBU brand. Wherever possible, we provide these features without accounts or uploads of personal content.

Information we do not collect

The current versions require no registration or sign-in. We do not include advertising, user profiling, cross-app tracking or third-party analytics, and do not collect names, phone numbers, email addresses, precise location, contacts, photos, health information or payment information.

Information stored on your device

Readings, charts, favourites, notes, questions, messages and app preferences are stored by default only on your device or in local browser storage. We cannot read this content on our servers.

Sharing

Selected content is passed to a destination only when you actively use a system or web sharing feature. You decide whether to continue, which fields to include and who receives them.

Permissions and third-party services

A product requests a system permission only when a related feature needs it and explains the purpose first. Apple and services you choose may process necessary information under their own policies when you download through the App Store, share or use voice input.

Children’s privacy

We do not knowingly collect children’s personal information. Minors should use the products with guidance from a parent or guardian.

Security and deletion

Local storage reduces remote transmission, but you remain responsible for the security of your device. Content is generally not recoverable after deleting an app, clearing its records or removing browser site data.

Changes to this policy

If we add accounts, cloud sync, analytics, advertising or another feature that changes data handling, we will update this policy before enabling it and provide notice where required.

For questions about this policy or our data practices, email izb@izb.app.
