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. If you sign in with WeChat or QQ, we collect the unique user identifier (UnionID) returned by that platform to create and recognise your account; we do not obtain your social contacts or chat history. See the Third-Party Information Sharing List for details. 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 and usage info: once you accept this policy, we collect an anonymous device identifier, device model, OS and version, screen resolution, language and region, mobile carrier, app version, plus screen views, feature-usage events, app start-up time and crash diagnostics. We use this to understand how features are used, improve the product and diagnose crashes. Before you accept this policy we collect none of the above, and this is enabled in release builds only.
This analytics and diagnostics data is sent only to a server we operate ourselves, is handled by us alone, and is not provided to any third party. We do not collect your amounts, balances, budget limits, notes, account and category names, the last four digits of card numbers, phone number, nickname or sign-in credentials.
Third-party sign-in and social sharing: we use MobTech ShareSDK, a service of the third party 上海掌之淘信息技术有限公司 ("MobTech"), to provide social sharing and third-party sign-in. To make these features work you need to authorise ShareSDK to provide the corresponding service; once you do, MobTech will collect personal information relating to you. For the categories of information MobTech collects, the purposes, its personal information protection rules and its opt-out mechanism, see the ShareSDK Privacy Policy.
Before you accept this policy the SDK is not initialised and collects nothing. Unlike the analytics and diagnostics data above, which we handle ourselves, information collected by ShareSDK is sent to 上海掌之淘信息技术有限公司 and to the social platform you choose (WeChat and QQ are both operated by 深圳市腾讯计算机系统有限公司, Shenzhen Tencent Computer Systems Co., Ltd.) — not solely to a server we operate ourselves. We do not transmit your bookkeeping data through this SDK. See the Third-Party Information Sharing List for the exact categories collected, the purposes and how to opt out.
Alongside ShareSDK this app also integrates its WeChat platform module and QQ platform module (both supplied by MobTech), which follow the WeChat Open Platform / QQ Connect protocols to launch the WeChat or QQ client installed on your device for authorisation and sharing; the package contains no Tencent SDK code of its own. When you actively use those features, Tencent processes the relevant personal information under its own rules — see the WeChat Open SDK Personal Information Processing Rules and the QQ Connect SDK Privacy Protection Statement. The only information we obtain and use from these two platforms is the unique user identifier (UnionID / OpenID) used to create and recognise your account. In the WeChat app you can review and revoke this app's authorisation under "Me — Settings — Privacy — Personal Information & Permissions — Authorisation Management".
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.
Personalised recommendations and targeted push: this app offers no personalised recommendations, personalised content or targeted push notifications, shows no advertising of any kind, and does not build user profiles, run precision marketing or make automated decisions based on your personal information. Everything shown on the home, statistics and assets screens is computed from the data you recorded yourself, using fixed rules such as date and category — no algorithmic recommendation is involved, which is why there is no "turn off personalisation" switch to offer. The analytics and diagnostics described in section 1 are used only to understand feature usage in aggregate and to diagnose crashes, never to push personalised content or ads to you. Should we add such a feature in future, we will update this policy beforehand, seek your separate consent, and provide a convenient way to turn it off.
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 the third-party SDKs, see the Third-Party Information Sharing List.
5. Your rights
Access, correction and deletion: you may view, correct or delete your ledger data in the app at any time, and export a copy to keep yourself.
Withdrawing consent: you can revoke a permission granted to this app in your system settings to withdraw consent for that collection; turning cloud sync off stops any further upload of ledger data. Withdrawal does not affect processing already carried out on the basis of your earlier consent.
Deleting your account: you can do this yourself in the app, under "Profile → Account info → Security → Delete account". To confirm the request comes from you, a phone number must be linked first (the app walks you through it if none is linked) and an SMS code entered as a second confirmation. Once submitted, the account is closed immediately and signed out on every device, and the ledger data on this device is erased; your account information and cloud data are then deleted, within 15 working days at the latest (except where law requires a longer retention period). Deletion cannot be undone — export and back up anything you want to keep before you start.
If you can no longer sign in, or run into trouble deleting the account yourself, contact us via the email address or QQ group in section 8; we will verify your identity and handle it within 15 working days. Exercising any of these rights is free of charge.
6. Children and minors
We take the personal information of children and minors seriously. In this policy, child means a minor under 14 years of age.
This app is a bookkeeping tool for general users. It is not designed for children and contains no social, livestreaming or gaming features. If you are a child under 14, please read this policy under the guidance of your guardian and obtain their consent before using the app; if you are a minor aged 14 or over, we suggest reading this policy together with your guardian.
A guardian may exercise, on behalf of the child in their care, all of the rights described in section 5 — including accessing, correcting and deleting the child's personal information, withdrawing consent previously given, and deleting the account the child uses.
We do not set out to collect children's personal information. If we find that we have collected it without a guardian's prior consent, we will delete the data as soon as possible. If you are a guardian and discover that a child has used this app or given us personal information without your consent, please contact us as described in section 8 and we will verify and delete it promptly.
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.
