BizBook (“the app”, “we”, “us”) is a business-management app — invoicing, point of sale, and inventory — published by Dr. Nzozone Henry Fomukong. This policy explains what data the app handles, why, and your choices. Plain language, no surprises.
a) Business data you enter. Products, inventory, batches, sales, invoices, estimates, clients, suppliers, expenses, payments, bank/cash balances, and staff records you choose to add.
b) Account data (only if you enable Cloud). Your email address and an encrypted password, handled by our authentication provider (Supabase) to sign you in and sync your data. We never store your password in readable form. Account emails — sign-up verification codes and password-reset codes — are delivered through our email service provider (Brevo), which processes your email address solely to deliver those messages.
b2) Voice input (only if you use voice entry). If you use the optional voice-entry feature to dictate a sale or expense, your speech is converted to text using your device's speech-recognition service (which may be provided by Google on Android). We receive only the resulting text, which you review before anything is saved. The microphone is used only while you actively hold the record button.
c) Images you submit to AI features (only if you use them). When you use Scan-to-Inventory or Invoice/Receipt OCR, the photo is sent — through our secure backend proxy — to our AI provider (Anthropic) to extract text and product details. Natural-language report questions are sent the same way. Images and queries are used only to return your result; they are not used to train AI models.
d) Technical/diagnostic data. Basic crash and error information to keep the app stable. No advertising identifiers are collected.
We do not collect contacts, precise location, health/clinical records, or browsing history. BizBook is a business-operations tool, not a health-records system.
Device permissions the app may request, and why:
Every permission is optional: denying it disables only the matching feature.
| Purpose | Data used |
|---|---|
| Run the app's core features on your device | Business data (a) |
| Cloud backup & multi-device sync (optional) | Business data (a), account (b) |
| Sign-in and account security | Account (b) |
| AI data entry & reports (optional, metered) | Images/queries (c) |
| App stability | Diagnostics (d) |
| Process subscriptions & purchases | Handled entirely by Google Play Billing — we never receive your card details |
We share data only with the service providers needed to run the features you use: Supabase (cloud auth/database/storage, only if you enable Cloud), Brevo (delivery of account emails — verification and password-reset codes — only if you enable Cloud), Anthropic (AI processing, only when you use an AI feature), Google Play (payment processing), and your device's speech-recognition service (voice-to-text, only when you use voice entry). We do not sell your data, share it with advertisers, or use it for advertising.
Local data is kept until you delete it or uninstall the app. Cloud data is kept while your account is active and removed when you delete your account.
BizBook is intended for business owners and staff. It is not directed to children and we do not knowingly collect data from children.
We may update this policy; material changes will be reflected by the “Last updated” date above and, where appropriate, noted in the app.
