Where is your Signal data stored?

When an user use Signal, his/her data would get stored in encrypted form on your device only . The only information that is stored on the centralized Signal servers for each account is the phone number a user registered with, the date and time he/she joined the service, and the date he/she last logged on.

As per Signal official statement “Notably, things we don’t have stored include anything about a user’s contacts (such as the contacts themselves, a hash of the contacts, any other derivative contact information), anything about a user’s groups (such as how many groups a user is in, which groups a user is in, the membership lists of a user’s groups), or any records of who a user has been communicating with. All message contents are end-to-end encrypted, so we don’t have that information either”.
