Privacy First Design

Your secrets stay secrets.

We built CopyStack with a paranoid level of privacy. It runs entirely within your browser's sandbox. No data analytics, no "cloud sync" features that leak data, and no third-party tracking.

Local Storage Only

Data is stored in `chrome.storage.local`. It never touches a server.

Proprietary Security

Closed-source architecture ensures tamper-proof integrity and security through obscurity.

Secure Enclave
chrome.storage.local AES-256 (System)
