ZeroKeepChat is a free, browser-based messaging service built on a simple premise: the safest place for a conversation to live is nowhere.
Why it exists
Most messaging platforms are built to remember. Conversations are written to databases, backed up, indexed, and retained indefinitely — which makes them available to breaches, to acquisitions, to policy changes, and to anyone who later gains access to the account. Even products that advertise disappearing messages usually keep the underlying record.
ZeroKeepChat takes the opposite approach. Messages are relayed in memory and discarded when the session ends. Photos dissolve after viewing. Calls run peer-to-peer and never touch our servers. There is no conversation archive, because none is ever written.
What that does and does not mean
We try to be precise about this rather than absolute, because the distinction matters. Zero retention means your conversations cannot be leaked from our servers, handed over in bulk, or mined later — there is nothing there to take. It does not mean we hold no data at all: accounts, contact lists, moderation records, and sign-in logs including IP addresses do exist, because account security and abuse prevention are impossible without them. Our Privacy Policy sets out precisely what is kept.
It also does not mean a conversation is beyond the reach of the person you are talking to. Anyone can photograph a screen. We protect you from us; we cannot protect you from your counterpart.
How it is built
The service runs entirely in the browser, with no app to install. Real-time messaging is handled by Cloudflare Workers and Durable Objects, authentication by Firebase, and calls by direct WebRTC connections between participants. Chat messages are held in server memory for the life of the session and never committed to disk.
What it costs
Nothing. ZeroKeepChat is free, carries no advertising, sells no data, and has no paid tier. There is no business model that depends on knowing more about you.
