About this app

Send files, photos, videos, and notes to your devices in seconds. Zas keeps things simple: send, open, save if you need it, and let the rest clear after five days.

WHY ZAS
• Encrypted before upload — Zas encrypts content on your device. Storage receives encrypted bytes.
• Built to sync — the service keeps the account, channel, delivery, and expiry metadata needed to sync and remove items.
• Fast for repeated files — content you already sent can arrive quickly.
• Clears after five days by default — pin an item to keep it.
• Share with people you choose — use channels and expiring links.
• Available on Android, iPhone, and the web at zas.red.

AGENTS ON YOUR COMPUTER
Connect an AI assistant on your computer to send files and notes to Zas. You choose the channels it can use, review its activity, and can revoke it at any time.

HOW IT WORKS
1. Sign in with Google, Apple, an 8-digit email code, or a passkey.
2. Choose a file, photo, video, or note and tap send.
3. Open it on another device, save it, or let it expire.

Zas is the app from zas.red. Search for Zas, zas.red, or ZasRed to find it.

What’s new

Sending on a poor connection. Everything you send now shows in the channel right away, dimmed, with one word for where it stands: queued, waiting for a connection, sending, or retrying. Sends wait for the connection and go out by themselves when it returns. Cancel any one of them with its cross. A note that cannot be sent goes back to the composer. Feed rows are more compact.
