FAQ
Reader questions
Does Delta store my message history on its servers?
By default, message history remains on your device, with optional end-to-end encrypted backups that only you can decrypt. Server-side metadata is minimized and never tied to readable content.
Can I use Delta on multiple Android devices with the same account?
Yes, you can securely sync your account across multiple Android devices. Each device maintains its own encrypted keys, and new devices must pass explicit approval and biometric authentication.
What happens if I lose access to my biometric unlock?
If biometric unlock fails, you can fall back to your strong account password or recovery phrase. Delta provides recovery options during setup to regain access without compromising encryption.
Are group chats in Delta end-to-end encrypted?
All group chats are protected by end-to-end encryption, with ratcheting keys that refresh with every participant addition or removal to preserve forward secrecy.
