Short answer: you don't need to. Start.me is cloud-based — your bookmarks, widgets, and settings are saved automatically to our servers every time you make a change. There's nothing to sync manually.
How it works
Start.me is not tied to a single browser or device. When you sign in on any browser, you see the same pages and bookmarks because everything is stored in the cloud. This is different from browser-native bookmarks (like Chrome's bookmark bar), which are stored locally and rely on the browser's own sync.
Same page open on multiple devices?
If you have the same Start.me page open on two devices at the same time, edits on one device won't automatically appear on the other. To see the latest version, press F5 (or Ctrl+F5 for a full cache refresh) to reload the page in your browser.
Want to bring your browser bookmarks into Start.me?
You can import bookmarks from your browser into Start.me. This is a one-time import — after that, Start.me manages them independently in the cloud.
