# Zas

> Zas (zas.red) sends files, photos, text and code between your devices, or to anyone, with nothing to install. Content is encrypted on the device before it leaves; the database and storage receive only encrypted data. Every item deletes itself five days after it is sent unless it is pinned. Direct mode moves a file device to device without storing it. Coding agents connect through the zas-agent MCP server. Zas for Enterprise adds an organization with roles, per-member limits, a custom domain on shared links and an exportable audit log.

Zas runs in the browser at https://zas.red and as an app on Android and iOS. The public pages exist in Spanish (the default, at the root), Portuguese (under /pt) and English (under /en). Every page below has the same content in the other two languages at the matching path.

- [Compare](https://zas.red/en/compare): Zas next to WeTransfer, AirDrop, Google Drive, Dropbox, Smash, SwissTransfer, TransferNow, LocalSend, Snapdrop and Send Anywhere — what each one solves, what happens to a file after it is sent, why Zas also moves files both ways between your own devices, how to get a file from an iPhone to a Windows PC, and what stands in for AirDrop on Windows and Android.

## Facts

- Items delete themselves five days after they are sent. A pinned item stays until it is unpinned.
- Content is encrypted on the device. The database and storage receive only encrypted data.
- Direct sends a file device to device, encrypted, without storing it. Both devices need Zas open; if the network requires it, Zas uses a relay.
- An anonymous session lasts 2 days and holds 30 MB. A free account holds 100 MB and can pair up to 5 agents.
- Items an agent sends carry an agent mark in the channel and delete themselves after 5 days.
- Zas for Enterprise costs USD 8 per seat per month, starts with 5 seats and a 14-day trial, and needs no card to begin. It requires a verified work email.
