Helium Synk

Privately sync bookmarks, sessions and browsing history across your Helium installations using a relay you control. - Merge bookmarks and folders across paired devices. - Browse current sessions, closed windows and previous snapshots. Restore pages explicitly without closing the source session. - Search received history by title, URL, source profile and date. - Keep locally committed work available offline and reconcile when the relay returns. - Enable only the collections you want. All collections start off. Content is encrypted before transmission. Run your own Rust relay behind private Tailscale HTTPS and pair installations through expiring invitation files. Separate contexts use separate accounts and keys. Requires a compatible Helium browser and your own configured relay. Passwords, cookies, browser settings and installed extensions are excluded. Browser-profile secrets and decrypted local caches are not encrypted at rest by this extension. Backups and exported files are separate sensitive copies you control. This community project is not an official Helium service. Setup instructions and source are available at the project homepage.
