We build software that respects your privacy. Our flagship product, ShieldPass, keeps your passwords encrypted and stored entirely on your device — no servers, no accounts, no data collection.
We are a software development company headquartered in Shanghai, China, committed to building tools that prioritize user privacy and data sovereignty.
Shanghai Erli Technology Co., Ltd. (上海尔励科技有限公司) was founded with a clear mission: to create software that gives users full control over their personal data. In an era where most applications rely on cloud storage and data transmission, we take a different approach.
We believe that sensitive information — especially passwords and credentials — should never leave a user's device. Our development philosophy is rooted in the principle that true security means zero network dependency for personal data.
Every product we build is designed to function entirely offline, with no background data collection, no telemetry, and no server-side processing of user content. We earn trust through transparency and technical integrity, not through marketing claims.

Privacy-first, offline software development
User data stays on the user's device — always
A password manager that works entirely offline. No accounts, no servers, no data transmission — ever. ShieldPass is our flagship application — a password manager designed for users who demand the highest level of privacy. Unlike conventional password managers that sync data to cloud servers, ShieldPass encrypts and stores all data locally on your device. The application does not request any unnecessary permissions, does not access the internet, and does not collect or share any user data. Your passwords, notes, and sensitive information are protected by strong encryption and remain accessible only to you.
ShieldPass operates entirely offline. No internet connection is required, and no data is ever transmitted to external servers.
All passwords and sensitive data are protected using industry-standard encryption algorithms. Your master key never leaves the device.
The app requests no unnecessary permissions. It does not access your contacts, camera, microphone, location, or any other sensitive device features.
All your data is stored exclusively on your device. There is no cloud sync, no backup server, and no shared storage. You own your data completely.
We are committed to transparency about how our software handles your information. This policy applies to all products published by Shanghai Erli Technology Co., Ltd.
We do not collect any personal information, usage data, or telemetry.
Your data never leaves your device. No servers, no sync, no cloud.
No analytics, tracking, or crash reporting libraries are included.
Our apps request only the minimum permissions needed to function.
All data is encrypted on-device using industry-standard algorithms.
