How do I get and sync free credits?
After consent to the Huawei-hosted system privacy statement, the app automatically uses the current HUAWEI ID. New users receive 3 complete casts without separate registration or an app password. Sync credits from About; change accounts through system HUAWEI ID settings.
How do ads add credits?
Choose the home-screen ad button, watch the full ad, and confirmed completion adds 1 credit. Credits can accumulate in advance, with no daily ad-reward limit and no forced playback.
Do failed or repeated casts and history use credits?
Only a successfully completed result uses 1 credit. Failure, cancellation and timeout do not. Repeating the same lunar month, day and Chinese hour may give the same result; cancelling before confirmation or viewing an existing result uses no credit. One request is not charged twice. Viewing, expanding, collapsing and saving history use no credits.
Why does calculating need a connection?
A connection verifies server credits and settles successful calculations. The calculation itself runs on the device; local history can be viewed offline. Sync credits after your connection returns.
What can I sync to another device?
The same HUAWEI ID can sync confirmed credits. History and notes stay on the original device. Reinstalling or clearing app data may remove local records.
What if an ad has not added a credit?
A full viewing must be confirmed before 1 credit is added. Reconnect and sync to check your balance; the same reward is not credited twice. If unresolved, contact support with the time and on-screen message.
Can I decline location or ad permission?
Yes. True Solar Time is your choice; standard-time calculation works without location access. Ad permissions are separate, and declining does not affect calculations using available credits or local history.

Privacy questions and your rights
For access, correction, deletion or account closure, read the privacy policy and email support@bonnwl.com with HarmonyOS and the scope of your request. We verify and handle requests within 15 working days of receipt. Support will explain any identity verification needed. Do not send passwords or authorization codes.
What happens when I withdraw consent?
About → Privacy and data → Withdraw consent (关于→隐私与数据→撤回同意) attempts to revoke the current server session and reports a failure if online revocation cannot complete. After withdrawal, account, product-event and diagnostic requests stop on this device, and its session and queued diagnostics are cleared. This does not sign out of the system HUAWEI ID or automatically delete local history or server credits. Server-data deletion requires a separate request. On the next launch after withdrawal, the system requests consent again; declining exits the app. Location permissions and system advertising privacy settings can be managed separately in device settings.
How do I report a fault?
Contact Shanxi Bonnwenle Technology Co., Ltd at support@bonnwl.com with system/app versions, time and on-screen message. Redact private screenshot content. Do not send questions, passwords, authorization codes or precise location.
