Do you prefer keeping your messaging backups on your device rather than on a cloud server?
Signal has released version 8.30 for iOS and desktop, finalizing the platform's implementation of encrypted local backups. The update allows users to create encrypted chat archives to restore their data on other devices.
Why it matters
This release provides users with a standardized method to secure and migrate their communication history across different operating systems. By enabling local backups, the platform ensures that chat data remains encrypted and under user control rather than relying on cloud-based storage services.
Signal version 8.30 introduces encrypted local backups with no size restrictions, while hosted options cap free users at 45 days of media and 128 KB messages. Paid plans offer up to 100 GB of capacity, with disappearing messages under 24 hours excluded from all archives.
The players
Signal
Signal is an encrypted messaging service known for its focus on privacy and open-source software development.
The details
Users can now perform encrypted local backups on iOS and desktop, mirroring capabilities previously established on Android. The iOS client also introduces a direct, end-to-end encrypted Wi-Fi link for iPhone-to-iPhone data transfers, requiring a recovery key to ensure decryption.
Timeline
Encrypted backups were first introduced on Android in 2025.
Signal released version 8.30 on September 29, 2026.
The Tech Race
This move reflects a broader industry shift toward decentralized data management where platforms prioritize local, encrypted storage over centralized server archives. It positions Signal against rivals that rely on cloud-syncing, reinforcing its commitment to user-controlled privacy.
Users can now securely transfer chat histories between devices without risking data exposure to third-party cloud services. The introduction of 100 GB storage plans offers a pragmatic solution for long-term users to maintain extensive media archives.
The takeaway
Users should manage their recovery keys carefully, as these are essential for accessing encrypted backups. Maintaining periodic local backups can prevent data loss when upgrading to new hardware or switching between mobile and desktop environments.
