One reference. As many browsers as you like.

Tidy up your bookmarks.

In Settings › Cleanup, Twinmark looks through your reference browser for what you no longer need and shows you the list. Only what you tick goes, and the other browsers follow at the next sync.

Duplicate bookmarks

Finds bookmarks saved more than once, even in different folders, and lets you choose which copies go. The first one, in the browser’s order, stays.

Links that no longer work

Checks, when you ask, which links lead nowhere any more: pages gone and sites closed. Only clear answers count, and none of them starts ticked, because a private page can look gone to someone who isn’t signed in.

Nothing goes by mistake

Before removing anything, Twinmark backs up the whole reference, and you can restore that backup. It removes only the bookmarks you ticked, after you confirm, and never a folder.

With Safari as the reference

Twinmark can’t write to Safari’s bookmarks yet: the list tells you what to remove, and you remove it in Safari. With Chrome or a browser built on Chrome as the reference, Twinmark removes them for you.

What protects your data is never paid.

At least 30 days of backups, one-click restore and the safety brakes are in the free version and they stay there. You won’t see a purchase prompt inside an error, a confirmation or a restore.

The terms, in plain words

14-day trial

Only if you ask for it, never automatic. One per Mac, with no card and no account. When it ends the extra browsers pause, your bookmarks aren’t touched and backups go back to the free version’s limits; named snapshots you saved stay. If you then buy, they pick up where they stopped.

Licence

One Mac at a time: you can move it to another Mac whenever you like, from Twinmark’s Settings. Valid for all of version 1.x. It also works offline, as long as the Mac connects at least once every 60 days.

Refund

Within 30 days of purchase.

Not promised

Firefox and copying from Chrome to Safari aren’t promised. If they arrive in version 1.x, they’re included for anyone who has already bought.
