security
we can't read what you send.
the server only sees ciphertext envelopes. keys live on devices. cosmetic 2828 is not the crypto.
end-to-end sealed messaging
identity keys + ratchet sessions keep chats sealed. only intended devices decrypt.
sealed content
relay and offline queue store sealed bytes — not readable chat history.
voice + media too
notes and media arrive covered until hold. same sealed model as text.
handles, not phone numbers
sign in with Google or Apple. claim an @handle. discovery without your SIM.

faq
short answers.
is Popello actually private?
messages are end-to-end encrypted before relay. we can queue sealed envelopes for delivery. we do not hold the keys to read plaintext.
why 2828?
2828 is the look — a repeating seal token. confidentiality is on-device crypto. personalize the seal to any short number or emoji.
is it free?
yes. features are unlocked in free mode. invite friends to grow the club and unlock bonus seal styles.
what happens if i lose my phone?
readable history lives on your devices. losing every device can mean losing old decrypted history — that is the privacy tradeoff. queued sealed messages can still deliver when a device with the right keys comes online.
how is this different from Signal?
Signal is secure and serious. Popello adds sealed-by-default presentation — every msg can look like 2828-static until hold/swipe — plus burn, duress PIN, per-chat locks, and playful voice filters.
can i use it without a phone number?
yes. Google or Apple sign-in, then claim an @handle. no SIM required.
when is the mobile app available?
Android is live on Google Play. iOS is live on the App Store. Web is live at popello.chat/app. Same @handle on every platform.
what data is stored?
account basics and sealed delivery envelopes/blobs. not readable chat plaintext. local history on web is stored sealed on device.
who is Popello for?
13+ per terms. anyone who wants a chat that does not look like english over a shoulder.
