1. Data Collection & Storage

"Bistro Ledger" is a minimalist, local-first utility application. We do not collect, store, or transmit any of your personal information, ledger data, inventory records, or scanning history. All records generated by you are kept strictly offline and saved exclusively on your local device (using Apple SwiftData and local storage architectures).

2. Accounts & Registration

No account creation, login, or personal information is required to use our app. We do not track user identities in any form.

3. Third-Party Analytics & Ads

We are committed to providing a pure, interruption-free utility experience:

No third-party advertising SDKs are integrated.
No third-party analytics or behavioral tracking tools (e.g., Firebase, Umeng) are used.
No cross-app tracking mechanisms are present.

4. Device Permissions

To ensure core functionality, we request only the absolute minimum required permission:

Camera Access: Only utilized for scanning item barcodes to manage inventory stock. The camera is activated strictly when you initiate a scan, and image data is instantly discarded after the barcode text is securely extracted locally. No video or image is ever uploaded to any server.

5. Policy Updates

Since we collect zero data, your privacy is physically guaranteed at the highest level. Should future feature updates require any data paradigm shifts, we will appropriately amend this privacy policy and declare it clearly in our App Store release notes.
