About AChat — how transient anonymous chat works

AChat is an anonymous, transient chat app built to be genuinely simple: no signup, an optional password for in-browser end-to-end encryption, and automatic deletion after 10 days.

The design

AChat runs on free-tier infrastructure (Firebase Firestore + Hosting and FilesHub for files) with no paid plan and no usage billing. Data auto-deletes via Firestore TTL. Passworded chats are encrypted client-side so the server never sees the key.

Honest about the limits

Open chats are not private — anyone with the chat ID can read them. File bytes on FilesHub are not encrypted at rest; only the file metadata is encrypted on passworded chats. Standard hosting telemetry (IP, user-agent) is collected. AChat is anonymous by design, not anonymous against legal process.
