Keepmark

Private, end-to-end encrypted bookmark sync. Independent alternative compatible with xBrowserSync services and apps.

Keepmark keeps the same bookmarks on all your browsers and your phone. Everything is encrypted in the browser before it leaves: the sync service only ever sees ciphertext, and your password never leaves the device. It works with any xBrowserSync service (the official one, a community host or your own) and with the official xBrowserSync apps. A sync created in Keepmark opens there, and the other way round. Nothing to migrate. HIGHLIGHTS • Private by design: PBKDF2-SHA256 and AES-GCM in the browser. No telemetry, HTTPS-only services, no access to the pages you visit. • Never lose a bookmark silently: conflicts are never resolved behind your back. Choose take remote, upload local or merge, with a preview before anything changes. The side being replaced is backed up first. • Set and forget: bookmarks bar, other bookmarks and mobile bookmarks sync automatically, plus a "Sync now" button. • Toolbar icon shows at a glance whether you are in sync. FEATURES • Create a new sync or link an existing one (download, upload or merge) • Automatic encrypted safety backup before every destructive step • Encrypted export/import, compatible with Keepmark for Android • Find and remove duplicate bookmarks • Move your bookmarks to another sync service • Change password, activity log • 9 languages: English, Italiano, Français, Español, Deutsch, 日本語, Português (Brasil), Русский, 简体中文 PERMISSIONS Keepmark asks only for what sync needs. It has no content scripts and never reads web pages. Access to https sites is needed only to reach the sync server you choose.
