What we hide — and what we don’t.
A privacy product is only as good as its honesty about its own edges. So here it is, exactly: what stays hidden, what an observer can still see, and what “disappears” really means.
Cost to send

02
No company, no backdoor
E2E
Only the recipient can open it
Encrypted to the recipient’s key — not a node, not a server, not us. Because no operator sits in the path, there’s no backdoor to add or subpoena.
PQ
Post-quantum from day one
Sealed against future computers from the start — traffic captured today can’t be unlocked later.
No op
Carried by the network
No stealthtext server holds or relays your messages — so none can be compromised, compelled, or shut off.
03
What “disappears” means
After two weeks a network-wide expiry removes every message, for both sides — no server keeps a copy. Precisely: removed from honest nodes’ storage and unreadable to everyone. That’s a property of the honest network, not a mathematical impossibility — so we never say “gone forever.” The one absolute is confidentiality: encryption holds no matter who kept a copy. By default your device keeps nothing; local history is opt-in and deletable anytime.
04
Your identity stays yours
Address
No phone number, no contacts
No directory to join, no address book to hand over. The app can display your existing wallet contacts read-only, storing nothing new.
Receipts
No read receipts
Delivery status shows only the message’s own journey — never when, or whether, you opened something.
Won’t claim
What we won’t say
Not “invisible,” not “indistinguishable from a payment,” not “gone forever.” We claim only what we can keep.
Private by default. Honest about the edges.
