KanBridge & ToneBridge privacy policy

Applies to: 漢橋 KanBridge (com.kanbridge.app) and ToneBridge (com.isriver.tonebridge). Last updated: 2026-09-06.

This service is operated by llab08, Hong Kong, and these terms are governed by the laws of Hong Kong. The section below explains this product’s data handling and current availability.

Summary

Both apps work entirely offline. They do not collect, transmit, or share any personal data. There are no accounts, no analytics, no advertising, no crash reporting, and no network requests of any kind. Both apps ask for no device permission — the only entry in either Android bundle is the framework’s own app-scoped permission guarding a broadcast receiver inside the app, which grants no access to anything on your phone.

Data stored on your device

Your study progress (review history, card scheduling state, settings) is stored only in the app's private storage on your device. It is deleted when you uninstall the app.

Backups you create

The "Export" feature writes a JSON file that you choose where to save or share (via your device's share sheet). That file contains only your study data; the app never uploads it anywhere. What you do with the exported file is under your control.

Text-to-speech

Pronunciation uses audio bundled with the app and/or your device's built-in speech engine. No text is sent to any server by the app. Your operating system's own TTS engine may have its own privacy terms.

Children

The apps are rated for all ages and, because no data is collected, no data about children is collected either.

Changes

If a future version ever collects data (for example optional cloud sync), this policy will be updated first and the change will be described in the app's release notes.
