Account, backup, and multi-account (technical)
Buzzio ID and mnemonic
| Item | Behavior |
|---|---|
| Buzzio ID | Random 12-digit public address |
| Mnemonic | 12-word phrase; derives messaging keys on-device |
| Private keys | Never uploaded to Buzzio |
| Username | Optional @handle mapping |
| Auth binding | Firebase Auth synthetic identity for infrastructure |
Login on a new device: Buzzio ID + phrase. Phrase custody is the root of sealed-account security.
Public docs say Buzzio ID (not Ghost ID). See Glossary.
Encrypted backup / vault
Default: no Buzzio-readable private cloud inbox.
| Option | Notes |
|---|---|
| On-device encrypted export | Encrypted file on a path you control |
| Encrypted cloud backup | Encrypted blobs; unlock with backup recovery key you control |
Approximate plan positioning (product-authoritative if changed):
| Plan | Backup offer |
|---|---|
| Free | About 100 MB lifetime — positioned as full text backup |
| Premium | About 100 GB / year — text + media; priced in-app / store |
After Premium ends, cloud backup may be retained ~60 days, then removed. Losing the backup recovery key means that blob cannot be unlocked.
Phrase ≠ backup recovery key. See FAQ.
Multi-account / vault binding services exist for switching accounts without collapsing key custody.
Losing phrase + devices + unlockable backup ⇒ permanent loss of private key material. That is intentional.
Plan numbers and SKU separation: Premium and quotas.
Optional Bitcoin wallet
Same mnemonic can derive a non-custodial wallet path (18+). Treat the phrase as both messaging and funds access when wallet is enabled. Chain queries use public explorers/price APIs — see Subprocessors.
