External Services

Unlike the impression, Franz is very close to a web browser and does not need direct access to external service API's. That means Franz does not store any of your external service login credentials on your computer or on a cloud service. The only data that is stored are cookies and the browser cache – exactly as it is when using a web browser like Safari or Chrome.

If you explicitly opt in to synchronize your session data (session data usually does not contain any passwords) with your other computers, we will encrypt your credentials, using high security industry standards, and store them as long as necessary on our servers. The encryption of your data will happen on your computer. We will never have access to plain text credentials.

Franz does not store your password nor does it directly access your messaging service's account!
