Signal launches end-to-end encrypted cloud backups (Android beta)
Signal has begun beta testing a new cloud backup system, initially rolling out on Android. The service stores end-to-end encrypted backups that only users can unlock with their unique encryption key. Signal says cross-platform restore support (Android ↔ iOS) is a goal for the future.
Key points
- End-to-end encrypted backups stored on Signal’s servers; only accessible with the user’s encryption key.
- Cross-platform restore planned so users can move chats between Android and iOS.
- Media offloading to reduce local storage; different storage tiers available.
- Free tier: all messages + ~45 days of recent media (exact details may vary by region).
- Paid option for extended storage (examples mention ~100GB for about $1.99/month; pricing and availability may vary).
- Paid backups currently rely on Google Play billing in some regions, which can limit availability on non-GApps Android builds.
- Beta may be available via manual installs (GitHub) before full Play Store rollout.

Notes & privacy
Signal emphasizes that backups remain private and accessible only to the user via their encryption key. As with any cloud backup system, consider whether you want encrypted cloud copies of your message history and media on Signal’s servers.
