Nothing follows you.

Leet Browser is a free private web browser for Windows and Android. It has no account, no ads, no analytics and no telemetry. It blocks known trackers, opens sites over HTTPS first, hides cookie pop-ups, and keeps your bookmarks and settings on your own device. It has no server to send them to.

Where your data goes

It stays on your device.

History, bookmarks, settings and your vault live on your own computer or phone. They are never sent to us, because there is nothing to send them to.

Try the shield

Flip it and watch.

A made-up news page loads nine things. Turn the shield off to see what a page like this normally gets to learn about you. This runs in your browser and sends nothing.

https://news-site.example/story
    Requests9
    Blocked0
    Trackers that saw you0

    Leet's real list holds about 125 known tracker domains. A real page can load others that are not on it.

    What it does

    On from the first start. Nothing to set up.

    These protections are on by default on both platforms. You do not have to find a settings page first.

    Shield card

    See exactly what was stopped

    Click the shield chip in the address bar. A card opens with the number of trackers blocked on this page and every host by name, with a count each. It says plainly that none of them got a connection, and the list stays on your computer. Switching protection off for a site is a separate, deliberate row at the bottom.

    Tracker shield

    Blocks them before they connect

    Known third-party trackers and ad hosts are refused and counted. Turn the shield off for one site if a page breaks.

    HTTPS first

    Secure version, every time

    Typed links, page links and redirects are tried over HTTPS first. A page with no secure version is plainly marked NOT SECURE. Windows also has an HTTPS-only mode, on by default, that never drops to http without your click.

    The gate (Windows)

    Every secure connection is checked

    All https traffic passes a small checkpoint on your own computer. Blocked hosts get no lookup and no connection. A tracker hiding behind a first-party name is caught too. Nothing is decrypted or stored.

    Private tabs

    Held in memory, then gone

    Private tabs use a separate session with no folder on disk. When the last private tab closes, its cookies and site data are dropped. They are never saved in history or "reopen closed tab".

    Cookie banners

    Hidden, never accepted

    Consent pop-ups are tucked away and the page scrolls again. Leet never clicks Accept on your behalf.

    Look-alikes

    Warns before you get fooled

    Addresses that imitate another site with tricky letters get a LOOK-ALIKE? warning, checked on your device with no lookup service.

    Jump-aways

    Pages can't hijack you

    If a page tries to send you to another site without a tap, Leet holds it and asks: Stay here or Go anyway.

    Per-site permissions

    Asked each time

    Camera, microphone and location are asked for each site until you choose to remember the answer. Review or forget them in one place.

    Signed updates

    Nothing installs unchecked

    On Windows, an update must carry a signature that matches a key built into the app, and its size and SHA-256 must match, or it is thrown away. It installs when you restart or close the browser.

    What leaves your device

    The sites you open. Nothing else.

    This is the whole list. If a connection is not in this table, Leet is not supposed to make it. The Verify page shows how to catch it if it does.

    On Android, updates come from Google Play and the phone's web engine is updated by Google. We switched off the parts of Android's web engine that would otherwise report to Google by themselves: Safe Browsing lookups, usage and crash metrics, and form autofill uploads. On Windows, Chromium's own background services (sync, update, Safe Browsing, translation, pings, crash upload) are switched off at start, and a test in our build fails if a new network call appears in the wrong place.

    Windows and Android

    Same promise, different parts.

    The two apps follow one rule: the user comes first. They are built differently, so some things differ. Here they are.

    With Leet Assistant. Leet Assistant is my separate offline assistant app. If you install both on one phone, the browser can hand it a ticket or bill after your tap, and the Assistant's vault can fill logins. They talk only to each other on the device. Windows can link to your phone's Assistant with a one-time QR code over your home network or Bluetooth, with a matching 6-digit confirmation on both screens. Neither app needs the other. Meet Leet Assistant.

    Limits

    What it can't do.

    Trust comes from honest limits. No browser can make you invisible, and this one says so. If you need anonymity, use Tor Browser. If you need the strongest fingerprinting resistance, use Mullvad Browser.

    Leet promises

    • No telemetry, accounts or ads. The apps have no tracking code and no server of ours to send it to.
    • Only what you open leaves your device, plus your search words to the engine you picked, plus (Windows) the switchable update notice.
    • Protections on from the start. Tracker shield and HTTPS first need no setup.
    • Page text is just data. A web page can never give the browser or the Assistant an order.

    It can't promise

    • Every tracker. It blocks a known list of about 125 domains; new or hidden ones can still slip through.
    • Anonymity. Sites you visit still see your IP address, and so do your network and DNS provider. Leet is not Tor or a VPN.
    • Fingerprinting resistance. Leet does not try to make all users look the same, as Mullvad and Tor do.
    • Open source. The source code is not public yet, so you can't audit it line by line. That is why we publish ways to check it from outside.
    • Independent audit. No third party has audited Leet yet, and it has no PrivacyTests.org result yet.
    • Plain http pages are visible to anyone on the way. They are labelled NOT SECURE.

    Leet Browser is made by one person, v3n0mt3ch, in Ayodhya, India. It is free. There is no paid tier, no ads, no affiliate deals, and nothing is sold, because nobody is paying for a server that could do it.

    I would rather you find a limit here than a surprise later. If you spot a connection or a claim that does not match this page, write to hi@v3n0mt3ch.com. I will treat it as a bug.

    Questions

    Things people ask.

    Is Leet Browser really free of telemetry?

    Yes. It has no analytics, no crash reporting, no advertising code, no accounts and no server of its own. The only thing it fetches by itself on Windows is a small signed update notice from GitHub, and that can be switched off in Settings. The Verify page shows how to check this yourself.

    Is Leet Browser open source?

    Not yet. The source code is private today, so it can't be audited line by line. We publish installer hashes, signed update details and a recipe for watching the browser's network connections, so the key claims can be checked from outside.

    Is it as private as Tor Browser or Mullvad Browser?

    No, and it doesn't claim to be. Leet blocks known trackers, tries HTTPS first and keeps nothing on a server, but it doesn't hide your IP address and doesn't try to make all users look identical. Use Tor Browser for anonymity and Mullvad Browser for strong fingerprinting resistance. Leet is for people who want a calm, tracker-free everyday browser with nothing to configure.

    What is it built on?

    The Windows version is built on Chromium through the Chromium Embedded Framework (CEF 154), with Chromium's background services switched off. The Android version uses the system Android WebView, which Google updates through Google Play.

    Which systems does it run on?

    Windows 10 and 11 can install the beta today. Android is coming soon to Google Play. There is no macOS, Linux or iPhone version.

    Windows says "unknown publisher". Is it safe?

    The installer is not code-signed yet, because a signing certificate is a paid yearly cost we haven't taken on. Windows SmartScreen therefore may show a warning. Check the file's SHA-256 against the one on the Verify page before you run it. If it matches, it is the file we published.

    How does Leet make money?

    It doesn't. It is free, shows no ads, sells no data and has no paid tier. It is built by one independent developer.

    Can I see which trackers were blocked?

    Yes. Click the shield chip in the address bar and a card lists every blocked host on that page with a count. Leet only blocks other companies’ requests; the site you opened is never touched. The list stays on your device.

    Does it keep my browsing history?

    Yes, on both Windows and Android, so you can find a page again. It is stored only on your own device and never leaves it: there is no sync, no account and no server to send it to. Private tabs are never added. You can remove single pages or clear it all at any time, and on Windows you can switch it off in Settings.

    How do I report a problem or a privacy concern?

    Email hi@v3n0mt3ch.com. If you see Leet make a network connection that is not in the table above, we want to know and will treat it as a bug.
