App: Inventory · Last updated: May 26, 2026
This document lists what information the Inventory mobile application (the “App”) may process. The App is a pure standalone tool: it does not sync to our servers, does not upload your business data, and does not require an account or internet for core features. For questions, contact app@91lxh.com.
The following is entered by you and saved in local app storage only. It is never uploaded to us or any third-party server by the App.

| Export / import backup | JSON backup you export or paste (contains the data above) | Data backup and migration at your initiative | You control — clipboard or files you choose |
You may edit or delete this data in the App, clear app data in system settings, or uninstall the App (local data may be removed unless you exported a backup).

No account registration is required. We do not ask for your real name, email, or phone number to use core features.
The App may request the following permissions only to support on-device features. None of them are used to send your data to us over the network.
| Permission | Purpose | Required? |
|---|---|---|
| Storage / files | Export or import backup files you choose on your device | Only when you use backup |
| Vibration | Local UI feedback (if supported by the device) | Optional |
Inventory features (products, stock, orders, reports) do not require internet access. The App does not use network access to collect or upload your personal or business data.
The App does not integrate third-party advertising, analytics, social-login, or cloud-sync SDKs. Charts and statistics run entirely on your device. We do not receive your business data through the App over the internet.
