ClipFlow — Your personal, secure clipboard between Android and PC
Instant text synchronization. No third-party servers. 100% data control with Zero-Knowledge architecture.
Mockup: Android phone next to a Mac screen
Core Features
Zero-Knowledge Architecture
Your data is encrypted locally (AES-256-GCM + scrypt). No one, not even the developer, can access it.
Your Personal Server
No third-party servers. You use your own free Firebase account for synchronization.
Instant Synchronization
Copy on your phone, paste on your Mac/PC in milliseconds. It just works.
Cross-Platform
Native support for Android, macOS (Intel & Apple Silicon), and Windows.
How it works
Data is encrypted on your device using robust algorithms (AES-256-GCM + scrypt) and a password only you know. Synchronization occurs through your personal Firebase account, which prevents data from being transferred to third parties.

Frequently Asked Questions
Do I need to pay for Firebase?
No, the free Spark plan is more than enough for years of personal use. Its limits are huge for this kind of task.
Where is my password stored?
Only in your head and locally on your device after encryption. It is never transmitted over the network.
Will there be a version for iOS?
An iOS version is planned for the future, but there are no exact dates yet. The main difficulty is the high cost of an Apple Developer account ($99/year).
Is the project open source?
Not at the moment, but the core cryptographic libraries used are open and well-vetted. The source code may be opened in the future.
