bitwarden takes security very seriously when it comes to handling your sensative data. Your data is never sent to the
bitwarden cloud servers without first being encrypted on your local device using [AES][aes] 256 bit encryption. You can read
more about bitwarden encryption [here][encryption]. bitwarden never stores meaningful data on its servers.
When your devices sync with the bitwarden cloud servers, a copy of the encrypted data is downloaded and securely stored
to your local device. Whenever you use the bitwarden apps or extensions your data is decrypted only in memory as needed.
Data is never stored in its decrypted form on the remote bitwarden servers or on your local device.
bitwarden servers are securely hosted and managed in the [Microsoft Azure cloud][azure].
