Absolutely. TabMaster is code signed and notarized by Apple, so macOS Gatekeeper can verify it hasn't been tampered with. The renderer uses context isolation with no Node access. Your sign-in token is stored safely in macOS Keychain — Apple's encrypted, OS-level vault. We don't store passwords or browsing data in the Keychain. All IPC payloads are validated. No browsing data is collected.
Gatekeeper may show a standard macOS prompt the first time you open TabMaster. This is normal for signed and notarized apps and is macOS confirming the app is verified by Apple. You do not need to bypass Gatekeeper or run any special commands.
TabMaster uses macOS Keychain to securely store a small session token that keeps you signed in and syncs your Pro status. Keychain is Apple's built-in encrypted vault — the same one Safari and Mail use. We never store passwords or browsing data there. If macOS shows a prompt, it's simply confirming that TabMaster can access the token it created. This is standard macOS security.
macOS requires this for AppleScript to read tab data from browsers. It's a one-time grant that enables cross-browser tab access. If denied, TabMaster surfaces a clear automation permission error.
No. TabMaster disables Chromium background throttling, uses a powerSaveBlocker, and pre-loads the renderer at startup for instant popover activation. It runs outside the browser sandbox with minimal resource usage.
