Your Privacy First (Zero-Knowledge)
By design, the birth details you enter are processed and stored on your own device and are not transmitted to or stored on our servers, unless you actively choose to enable cloud backup.
1. Purpose of Collection
The birth details you enter — date, time, gender and birth city/location — are used for one purpose only: to calculate your BaZi (Four Pillars of Destiny) chart and the related daily, natal and luck readings on your device. Your birth city is converted to coordinates on your device to compute True Solar Time.
2. Voluntary Supply
Supplying these details is entirely voluntary. If you do not provide them, the only consequence is that the app cannot calculate a chart for you; there is no other consequence.
3. Optional Cloud Backup and Account Data
If — and only if — you choose to sign in to enable cloud backup, the profiles you have saved, together with the account identifier from our authentication provider (such as your email address or a Google account ID), are transmitted to and stored in our cloud database so that you can restore them on another device.
4. Classes of Transferees
We do not sell your personal data and we do not use it for direct marketing. Your personal data may be handled by:
- our cloud service provider, Google Firebase, acting as our data processor; and
- regulators, law-enforcement, or our professional advisers, where reasonably necessary or required by law.
5. Retention
Local data is kept on your device until you delete the profile or clear the app’s data. Any data held in cloud backup is kept until you delete it or close your account, after which it is removed within a reasonable period.
6. Your Access and Correction Rights
You have the right under the Ordinance to request access to, and correction of, your personal data held by us. As most data never leaves your device, you can exercise these rights directly in the app by viewing, editing or deleting your saved profiles. For any data held in cloud backup, contact Bilibala Shadowpaw Limited at info@bilishadowpaw.com. As permitted by the Ordinance, we may charge a reasonable fee for a data access request, and we will respond within 40 days.
By entering your birth details, you acknowledge that you have read and understood this statement.
