Privacy
What the Browser blocks, what it sends, and where each privacy setting lives.
The Browser sends no telemetry and no analytics. Its privacy features are on from the first page you open, incognito windows included. Most of them live in Settings → Privacy and security; saved logins have their own pane, Settings → Passwords.
What's on from the start
| Feature | Default | More |
|---|---|---|
| Ad and tracker blocking | On | Ad blocking |
| Cookie banners | Reject automatically | Cookie banners |
| HTTPS | Upgrade when possible | Secure connections |
| Secure DNS | Automatic | Secure connections |
| Adult sites | Open in incognito | Incognito |
| Offer to save passwords | On | Passwords |
Ads and trackers
A blocker is built into the browser itself, not added as an extension, so pages stay fast. It uses EasyList, EasyPrivacy, and uBlock filters, checked for updates once a day. Right-click a page and uncheck Block ads on this site to let a site show ads. See Ad blocking.
Cookie banners
When a site asks about cookies, the Browser answers Reject for you. A banner it can't answer is hidden instead. It never clicks Accept. See Cookie banners.
Secure connections
Pages load over HTTPS whenever the site supports it. HTTPS only goes further and warns before a site without HTTPS loads. Secure DNS encrypts the lookups that turn site names into addresses. See Secure connections.
Passwords and passkeys
Saved logins are kept in a file only your computer's keychain can open, and they never leave your computer. See Passwords and Passkeys and security keys.
Incognito
Incognito windows keep their cookies and site data apart from your other windows, keep no history, and forget everything when the last one closes. Known adult sites open in an incognito window on their own. That check runs on your computer. See Incognito.
VPN extensions
If you use a VPN extension, the Browser holds pages at launch until the VPN has connected, so nothing loads around it. See VPN extensions.
Search
Searches go to the engine you picked in Settings → General. Web results and suggestions in the command center come from 1zero's own search server, which doesn't log what you type.
Clearing browsing data
Settings → Privacy and security → Clear browsing data removes data for every site, from the beginning. Tick what to remove, then press Clear data…:
| Choice | Removes |
|---|---|
| Cached images and files | Copies of pages and images. Pages may load slower the next time. |
| Cookies | Signs you out of most sites. |
| Site data | Local storage, databases, and service workers. |
Extensions keep their own data.
Site permissions
Settings → Privacy and security → Site permissions keeps your answers when a site asks for your camera, microphone, location, notifications, or clipboard. Reset one choice, or everything for a site, and it asks again next time.
Privacy mode
The Privacy mode plugin blurs emails, phone numbers, card numbers, IP addresses, and sign-in codes on every page before it's drawn, so you can share your screen without checking first. Install it from the Plugins page, then turn it on and off with ⌘Ctrl⌥AltB.
