Private browsing
A private browser for your Mac, in every Space.
Tern blocks known trackers and ad servers everywhere, keeps each Space's sign-ins apart, and gives you a private window that forgets everything when you close it.
Free · macOS 26 or later · Signed and notarized by Apple
Trackers stop at the door
- 106,293 trackers and ad servers
- Blocked in every Space, checked on your Mac before a page loads them. The list comes with Tern, so nothing about your browsing is sent to check it.
- If a site misbehaves
- Open the shield in the address bar and let that site through. Settings lists the sites you allowed.
Sign-ins kept apart
- Each Space keeps its own
- Cookies and logins never cross from one Space to another, so work accounts stay in Work and shopping stays in Home.
- Delete a Space, delete its sign-ins
- Removing a Space removes its cookies and website data with it.

Questions
Does Tern track me?
Tern has no account and no ads. It sends anonymous usage counts only if you say yes, and crash reports only if you turn them on. The privacy page lists every time it goes online.
Is private browsing the same as being anonymous?
No browser makes you anonymous on its own. A private window keeps your Mac clean and blocking keeps trackers out; the sites you visit and your network still see your connection.
