Privacy Policy

Last updated: 7 June 2026

BillBook Business helps Sri Lankan small businesses keep their own records. It is local-first: by default your data stays on your device and nothing is uploaded. This policy explains what we collect, what we deliberately do not, and the choices you control.

Local-first by default

Your invoices, receipts, cashbook entries, orders, stock and customer records are saved in the app’s storage on your own device. Unless you turn on optional cloud sync, none of it is sent to us or anyone else. Because the data lives on your device, clearing the app’s data or uninstalling it will remove it — so please keep your own backups (you can export your data at any time).

Signing in with Google

Signing in is optional — BillBook Business works fully without an account. If you choose “Continue with Google”, Google shares a limited part of your Google profile with us: your name, your email address and your profile picture. We use these only to create and secure your account and to sync your records into your own private, per-user, row-level-secured space — never to contact you for marketing, and never sold or shared with anyone. You can disconnect BillBook from your Google Account at any time, and delete your account and data from within the app.

Our use of information received from Google APIs follows the Limited Use requirements of the Google API Services User Data Policy.

Optional cloud sync

If you enable cloud sync, your records are stored in our secure cloud under per-user Row Level Security, so only you can ever read or write your own data. The app uses only a public key — never a secret key. You can export your data or permanently delete it whenever you like.

What we store

Only what you enter to run your business — invoices, receipts, cashbook entries, orders, stock, customers, and, if you sign in, your account email. Some of this is sensitive (for example, customer phone numbers) and is treated carefully and never sold.

What we deliberately do not do

BillBook is not a payments product: it does not connect to any bank, card processor or payment gateway, and never stores card, bank-account or payment-token details. Any LankaQR shown is your own bank-issued code. The everyday on-device coach works fully offline. The optional Smart Helper and Snap-a-bill are different: only when you choose to use them, your typed question with the relevant business figures — or the photo of a bill you scan — is sent securely over HTTPS to our processing service (which uses a trusted machine-learning provider) only to produce that answer or read that bill. It is never used for advertising, never used to train models, and never sold. We never sell your data or your customers’ details, and we do not show third-party ads.

Your controls

You can export your data at any time, and permanently delete your account and data from Account & cloud. You can disconnect Google from your Google Account settings.

Children

BillBook Business is intended for business owners and is not directed at children.

Changes to this policy

We may update this policy as the app evolves; the date above reflects the current version.
