Encrypted backup.

Your identity's lifeboat. Keys live only on your device, which is excellent for privacy and unforgiving about loss. The encrypted backup is the escape hatch: one file, sealed by your passphrase, that can rebuild your identity on a new phone.

// definition

An encrypted backup is an export of your keypair (and what's needed to restore your identity) encrypted under a passphrase you choose. Without the passphrase, the file is as opaque as any other ciphertext.

What it is

From Settings, export the backup and store it anywhere you like — a file vault, a drive, a safe. On a new phone, restoring it re-creates your identity, so your pairings and safety numbers stay valid instead of resetting.

Why it matters

No accounts means no cloud recovery — nobody upstream can reset what only you hold. That's the deal: stronger privacy, more personal responsibility. The backup converts catastrophic phone loss into a five-minute restore.

// in CarrierPony CarrierPony's backup is encrypted on-device before it's written anywhere. The developer cannot open it, which also means a forgotten passphrase cannot be reset — choose one you'll keep.

Common questions.

Where should I store the backup file?

Anywhere durable that you control — the passphrase is what protects it, so even ordinary cloud storage doesn't expose your keys. Two locations beat one.

What happens without a backup?

A lost or wiped phone means a lost identity. You'd generate a fresh keypair and re-pair with contacts, whose apps will correctly warn that your key changed.
