Overview

• The opt-in feature in the latest Android beta creates end-to-end encrypted archives so users can restore chats after device loss.
• The free option backs up all texts and the most recent 45 days of media, with daily refreshes that exclude view-once items and messages set to disappear within 24 hours.
• Decryption requires a 64-character recovery key generated on the device, and Signal cannot recover backups if the key is lost.
• Signal says archives are stored using zero-knowledge techniques without direct links to user accounts or payment details.
• Reported limits set free message storage at 100MB and the $1.99 per month plan at up to 100GB, with a public release, iOS and desktop support, and user-chosen archive locations planned.
