Gift & Return — Privacy Policy
Effective date: October 3, 2026
This Privacy Policy explains how SMJY Tech ("we", "us") handles information in the lishang mobile application ("the App"). We are committed to being transparent and to collecting as little information as possible — in fact, we collect none.
The App is fully offline
The App requires no account and never asks for personal data. Your gift ledger, people, events and settings live entirely in your device's local storage and never leave your device. We operate no server for user content, so we cannot read a single entry you note.
Contents
1. Who is responsible for your data
The data controller responsible for your information in the App is SMJY Tech. If you have any question about this policy or your data, contact us at tzhh0617@gmail.com.
2. Information we collect
Local data (stored only on your device). The App keeps your ledger entries, people, events and preferences in the device's local storage. This data is never sent to us or to any server. No analytics, no tracking, no crash reporting. The App embeds no analytics, advertising or crash-reporting component and no third-party tracking SDK.
3. How and why we use information
We do not collect, use or share any of your data — because the data never leaves your device. Exporting a CSV or a backup file is a local action you trigger yourself; where it goes is decided entirely by you through the system share sheet.
4. Third parties
We share your data with no third party, and there are no international transfers. Diagnostics and payments handled by the app stores themselves (Apple App Store / Google Play) are governed by their own privacy policies.
5. How long we keep information
Local data stays on your device until you uninstall the App — uninstalling erases it completely. We recommend keeping your own copies via the in-app "Export backup (JSON)" feature.
6. Your rights
Because your data lives entirely on your device, you have full control by design: uninstalling erases everything, and the export feature is your data portability. Questions about this policy: tzhh0617@gmail.com.
