What you get
A panel for the daily work, a manager page for the big cleanups.
Pinned sites, open tabs, bookmarks and downloads stop being four separate places you have to keep in your head.
Tabs that know their bookmark
When a tab drifts away from its saved URL, one click on the favicon takes it home. Closing a saved tab keeps the bookmark, and opening it again picks up the same tab.
Automatic tab archive
Sweep idle tabs into dated folders instead of losing them, and restore them any time.
Search everything
One box over your bookmarks, your open tabs and your history.
Manager page
A folder tree plus smart views (All bookmarks, Recently added, Unfiled, Downloads, History and Archive) for the search-and-destroy cleanup sessions that the panel is too small for.
Downloads
Recent downloads right in the panel, and a full downloads view in the manager.
Your data stays yours
Sign in to sync your bookmarks. We don’t look at, analyze or sell them.
An extension that reads your bookmarks and tabs asks for a lot of trust. Here is exactly what Onemark touches, where it goes, and what stays behind when you remove it.
Start locally, sync when you choose
Organize bookmarks, tabs and downloads locally without signing in. Bookmarks are sent to our service only when you sign in to sync. Error reports are a separate option, off by default.
Sync with your Jetto account
Sync is optional. Sign in with a Jetto account and your bookmarks follow you across Chrome profiles. Bookmarks are encrypted in transit over HTTPS and encrypted at rest by Cloudflare, where the sync service stores them. The sync service can read them, so the developer technically could. We don’t look at, analyze or sell your bookmarks. Delete your synced copy any time from the options page. Two profiles are free; Onemark Pro (US$1.99/month or US$12/year) syncs as many as you like.
Tabs and history stay on your device
Onemark asks for bookmark and tab permissions, so Chrome warns you about your browsing history. It needs them to organize what is already in your browser. Sync carries bookmarks only: your open tabs, downloads and browsing history are never synced or sent anywhere.
Nothing sold, nothing tracked
No ads, no tracking. The developer does not sell or share your data, or use it for advertising or AI training. Uninstalling removes the extension's own storage, and your bookmarks stay in Chrome.
