Code Share
WiFi Mode vs. Global Mode
Code Share lets you paste text or upload files and have them sync to any other device instantly. WiFi Modeauto-joins a room derived from your network's public IP - anyone on the same WiFi sees the content automatically, with no code or password to type. Global Mode works from any network via a short share code, with optional password protection for cross-network access.
Zero-knowledge: encryption (AES-256-GCM with PBKDF2 key derivation) happens entirely client-side. The server only ever stores opaque ciphertext - it never sees a plaintext or a password.
Files, previews, and expiry
Pasted text auto-linkifies clickable URLs, image files get an inline preview, and the whole file set can be downloaded in one click as a .zip. Uploaded files auto-delete after 7 days; a live participant counter shows how many devices currently have the share open.
