For the Karasoy eID Firefox add-on, please see the privacy policy at: https://gist.github.com/murattopcu73/cd13a09c8869e20f08129cd8e160aec0

Summary: Karasoy eID does NOT collect, transmit, or store any user data. It does not run analytics or share data with third parties. The extension only activates on supported sites (callturk.com.tr) and only communicates with the Karasoy eID native host (com.karasoy.eid) on the user's local machine when the user requests an e-signature. All cryptographic operations (certificate listing, signing, PIN entry) happen on the user's hardware (smart card / USB token). The private key never leaves the device.
