Note to Self
Note to Self is a private place to save text and supported media for your own account. Notes live on your devices. Buzzio does not offer a durable “sync to cloud” archive for Note to Self.
Encryption model
- On the phone, notes are stored in the local encrypted database.
- Multi-device (phone ↔ linked browser) uses a Notes Root Key (NRK) held on the phone and, while linked, on that browser session only. The account master key / 12-word phrase never leave the phone.
- Each note uses an envelope so the server only ever sees ciphertext.
- Restoring the same Buzzio account from its phrase restores local notes on a new phone. Linked web gets a fresh notes key and a one-time history handoff from the phone when you link.
This is account-bound private storage, not a 1-to-1 conversation and not a shared room.
Phone
- Open Note to Self.
- Save text or supported media — they stay on this phone.
- There is no Premium “keep forever on Buzzio servers” toggle.
Losing the 12-word phrase and all usable devices means Buzzio cannot recover the notes.
Linked web (`web.buzzio.dev`)
When you link a browser under Linked devices:
- The phone sends an encrypted history package once so the browser is not empty. Buzzio deletes that temporary transfer after the browser acknowledges it.
- New messages, edits, deletes, and stars go through a 3-day encrypted messaging mailbox. Both sides can fetch until each message expires — not delete-on-seen.
- After three days, server mailbox copies are hard-deleted. Whatever each device already saved stays local only.
- Unlink or session expiry wipes the browser’s notes key and local notes cache. Re-link starts a new key and a new history package from the phone.
Linked web Note to Self is a notes-only exception: it is not sealed 1-to-1 chat and does not put your seed in the browser. It is also not Saved Messages (Premium keep-forever thread with a 200 MB media pool). See Saved Messages and Why E2E chat is not on the web.
