The renowned end-to-end encrypted messaging app Signal has announced the launch of a cloud backup feature, allowing free users to back up chats and media from the past 45 days, while paid subscribers gain up to 100GB of storage.
For years, Signal deliberately avoided storing conversations of any kind, citing privacy concerns. If a user lost or damaged their phone—or accidentally deleted the app—all data would vanish irretrievably. The only exception was transferring chat histories directly between devices. The absence of cloud backups stemmed from the risk that compromised servers or intercepted transmissions could expose sensitive data. Now, however, Signal has introduced a zero-knowledge architecture to underpin its backup system, ensuring that all data is fully encrypted and indecipherable to anyone but the user.
For free users, the app will store up to 45 days of messages and media, with older content automatically purged from servers, though it remains available locally on the device. Storage capacity for free accounts is capped at 100MB.
Those requiring extended storage can subscribe for $1.99 per month, unlocking 100GB of encrypted cloud storage for long-term preservation of chat histories and multimedia.
When the backup feature is activated, the device generates a unique 64-character recovery key to decrypt the archive. Signal does not retain this key; therefore, if it is lost, the corresponding backups become permanently inaccessible.
The feature has been rolled out first for Signal on Android, with iOS and other platforms to follow soon. Looking ahead, Signal also plans to allow users to select alternative storage providers for even greater flexibility.
