Yes, but they are encrypted using 256-bit AES encryption before reaching Dashlane’s servers. All of the data in your vault is encrypted locally on your device before being sent to Dashlane’s servers, and the only way to decrypt that data is with your master password, which is also stored locally on your device. This means that if Dashlane were ever to be breached, your data would be completely safe.
Also, thanks to its zero-knowledge architecture, Dashlane’s employees cannot access any of your data, even in an emergency or if you forget your master password. But Dashlane offers one account recovery option — you can regain access to your vault in case of a lost master password if you enable biometric logins on your mobile device (the master password reset option must also be enabled) or in the Safari app. Dashlane also offers emergency access, so you can set up an emergency contact who can retrieve your data if they need to — however, it’s still being implemented in the new web app.
