Bibi Ledger is developed and operated by Luzhou Jinzhijiang Technology Co., Ltd. ("we"). We know how much your personal information matters, and we work hard to keep it safe. This policy explains what we collect, how we use and store it, and the rights you have.
1. Information we collect
Account: if you choose to sign in, we collect your phone number to create your account, verify your identity and sync data. You can also use every bookkeeping feature locally without signing in.
Ledger data: your transactions, categories, accounts and budgets are stored only in the local database on your device by default. They are encrypted and uploaded to our servers only after you turn on cloud sync.
Device info: to keep the app stable we may collect basic diagnostics such as device model, OS version and crash logs.
2. How we use it
Collected information is used only to provide bookkeeping, statistics, asset management, budgeting and sync; to improve the product; and to send necessary service notices.
We never sell your personal information, and we never use it for advertising profiles.
3. Storage
Local-first: your ledger lives on your own device by default. Uninstalling the app deletes local data — please back up first.
Cloud data: with sync on, data is transmitted encrypted and stored on servers within the People's Republic of China. When you delete your account, your cloud data is removed.
4. Sharing
We do not share your personal information with third parties, except with your explicit consent or where required by law or competent authorities. For details about third-party SDKs and hand-offs to third-party apps, see the Third-Party Information Sharing List.
5. Your rights
You may view, correct or delete your ledger data in the app at any time, export your data, or delete your account. Account deletion removes your account info and cloud data.
6. Children
We take children's privacy seriously. If you are under 14, please use the app under the guidance and with the consent of a guardian.
7. Updates to this policy
We may revise this policy from time to time. For material changes, we will notify you prominently, such as via in-app notices.
