xox — ephemeral private chat

xox is the ephemeral private chat — engineered so that your conversations leave no trace anywhere. Not on our servers, nowhere.

PRIVACY BY ARCHITECTURE, NOT BY PROMISE
Most apps promise privacy. xox is built so there is simply nothing to collect:
- No accounts — no phone number, no email, no sign-up
- No cookies, no analytics, no ads, no fingerprinting
- No message storage — zero content ever touches our disks
- No logs — we don't record who talks to whom, when, or from where

REAL END-TO-END, POST-QUANTUM ENCRYPTION
Every message is encrypted on your device before it leaves: ML-KEM-768 post-quantum key exchange + ECDH P-256, AES-256-GCM, Double Ratchet. Nobody in the middle can read it — including us. Verification codes let you confirm there are no intruders in your room.

EPHEMERAL BY DESIGN
Rooms are disposable. Close them and the conversation is gone, like it never existed. Asynchronous messages exist only as encrypted blobs we cannot open, auto-deleted on delivery.

PRIVATE CALLS THAT PROTECT YOUR IP
1:1 rooms and encrypted group calls (up to 5). All calls are relay-only through our own infrastructure, so participants never see each other's IP addresses.

HONEST BY DEFAULT
We won't tell you fairy tales: any internet connection technically exposes an IP to the server. The difference is what we do with it — nothing. No logging, no storing, no correlating. Read our one-line privacy policy: we store nothing.

10 LANGUAGES, RTL SUPPORT
English, Español, 中文, हिन्दी, العربية, Português, Русский, 日本語, Deutsch, Français.

Your conversations belong to you. xox makes sure it stays that way — by design
