Zero Say Browser
A browser that leaves nothing behind.
Zero Say Browser is the second app from Zero Say, alongside Zero Say Messenger. Every tab goes through Tor before it reaches the internet, so sites see a Tor exit instead of you. Trackers and ads are cut out before they load, your device is made to look like everyone else's, and when you close the window there is nothing left to find. No account, no sync, no analytics, no telemetry.

Three zeros, again
Nothing sees you, nothing follows you, nothing stays.
0
Zero exposure
Tor by default for every tab, fail-closed: nothing reaches the internet until Tor is ready. Bridges (obfs4, Snowflake, your own lines) get you through where Tor is blocked.
0
Zero tracking
Twenty-one filter lists, tracking parameters stripped from links you open, redirect trackers skipped, cross-site cookies and Referer cut. The lists are shipped inside the app and refreshed over Tor.
0
Zero traces
Burner by default: cookies, cache and history live in memory and are gone when you close. Downloads stay in a sandbox unless you deliberately keep one.
What it does
Built like Tor Browser. Feels like a normal one.
Security levels
Standard, Safer or Safest, the way Tor Browser does it: Safer runs scripts only on HTTPS and .onion sites, Safest runs none. Turn JavaScript on or off for a single site from the padlock.
Onion search
One search asks Ahmia, TorDex, OnionLand, Torch and Amnesia at the same time and merges the results, without leaving Tor. Sponsored placements are removed; results matching an abuse-term blocklist never reach the page.
Circuit display
See the three relays your page is using, with their countries, and ask for a new circuit for that one site without touching the rest.
Looks like everyone else
Fingerprint hardening makes your device report the same common Windows Chrome story as thousands of others: canvas, WebGL, fonts, screen, time zone, client hints.
Offline translation
Firefox's translation engine runs on your computer. Models download once, over Tor, and the page text never leaves your machine.
Reader view
Strip a page down to its article, rendered through a strict allowlist so no script from the page comes along.
Password vault
Logins are kept in the operating system's own secure storage and unlocked with Touch ID. Nothing is synced anywhere.
Upstream proxy
Optionally chain Tor into a proxy of your own, so sites see the proxy's address instead of a public Tor exit and cannot tell you use Tor. Onion sites still go straight through Tor.
Updates over Tor
The browser checks for updates through Tor, so even that never reveals your address to us. Updates are signed and install when you quit.

Tor and its pluggable transports are bundled; nothing else to install. Every build comes with a SHA-256 checksum on its page and is code-signed.
Honest limits
What it cannot do.
Tor is slower than a direct connection.
Three relays and a bridge, if you use one, add latency. That is the cost of the anonymity; there is no setting that removes it.
Fingerprinting cannot be made perfect.
We make the browser look common, not invisible. A determined site running its own tests may still find differences. We publish what we do rather than claim more.
What you type is yours to protect.
Logging into an account that names you names you, on any browser. The browser hides where you connect from, not who you tell a site you are.
Onion search shows what other indexes contain.
Results come from third-party onion search engines. We filter what we can, and we refuse to add an off switch for that filter.
Questions
Straight answers.
- Is this Tor Browser?
- No. Tor Browser is Firefox-based and the gold standard for anonymity; Zero Say Browser is built on Chromium with Tor underneath and its own hardening. If your safety depends on it, use Tor Browser. If you want a fast everyday browser that routes through Tor, blocks everything and forgets everything, this is it.
- Do I need to install Tor?
- No. Tor and its pluggable transports are bundled inside the app.
- Does it work where Tor is blocked?
- Usually. Turn on a bridge under Settings → Connection: obfs4 disguises Tor traffic as random data, Snowflake makes it look like a video call. You can also paste bridge lines you get from the Tor Project.
- Can I use it with the Zero Say messenger?
- They are separate apps that share the same promise. The messenger runs on its own; the browser is for the web.
The fine print for the browser: Security · Privacy Policy · Terms of Use.
Looking for the messenger? Zero Say is the encrypted chat app this browser shares its name and its promises with.
