TabMark: Tab Manager with Automatic Organization

All your saved sessions are stored locally using Chrome's sync storage API. Nothing is sent to external servers. If you have Chrome Sync enabled, your sessions will sync across your devices through Google's encrypted sync service - but TabMark itself never transmits data anywhere.

No. TabMark has no backend servers and no way to access your data. Only you can see your saved sessions, and they never leave your control.

All data stored by TabMark will be removed from Chrome's storage. If you've exported markdown files, those remain in your Downloads folder.

TabMark is designed for Chrome and Chromium-based browsers (Edge, Brave, Opera, etc.) that support Chrome extensions.

Yes! TabMark works completely offline since all data is stored locally.

TabMark is limited only by Chrome's storage quota (typically several MB), which can store thousands of tab sessions.

No. TabMark only saves your tabs. You decide when to close them. This non-destructive approach means you never lose work accidentally.

Yes! Saved sessions are standard markdown files. You can edit them, organize them, commit them to git, or process them with any text tool.

Bookmarks are permanent, require manual organization, and don't capture your work context. TabMark automatically timestamps every save, preserves window groupings, and creates a historical record of your browsing sessions.

Most session managers use proprietary formats and keep everything in the browser. TabMark exports to human-readable markdown, giving you portable, searchable, version-controllable session history.

TabMark is committed to complete transparency and user privacy. Here's our comprehensive privacy policy:

Data Collection: TabMark collects NO personal information, analytics, or telemetry. The extension only accesses tab URLs and titles when you explicitly click 'Save All Tabs' - never automatically or in the background.

Website Analytics: The TabMark website (not the extension) uses PostHog analytics to understand how visitors use the site and improve the experience. This includes page views, button clicks, and navigation patterns. Website analytics are anonymized, used only for website optimization, and you can opt-out via your browser's Do Not Track settings. The extension itself collects no analytics whatsoever.

Data Storage: All saved sessions are stored locally on your device using Chrome's sync storage API. If you have Chrome Sync enabled, your sessions may sync across your devices through Google's encrypted sync service, but TabMark itself never transmits data to any external servers or third parties.

Data Usage: Your saved tab data is used solely for restoring your browsing sessions. There is no profiling, advertising, analytics, or any secondary use of your data. You have complete control over when data is saved and when it's loaded.

Data Sharing: Zero data sharing. Period. TabMark has no backend servers, no databases, no advertising networks, and never sells or monetizes your data in any way.

Permissions Explained: TabMark requests minimal permissions: (1) 'tabs' permission to read tab URLs when you save sessions, (2) 'storage' permission to save sessions locally, and (3) 'notifications' permission to show confirmation messages when you save or load tabs.

Your Control: You maintain full ownership and control. Delete all data anytime by uninstalling the extension. Export your sessions as markdown files for complete portability. Your data never leaves your control.

Chrome Web Store Compliance: TabMark fully complies with Chrome Web Store Developer Program Policies. We practice transparent functionality with no deceptive practices, no hidden data collection, and no unexpected behavior. Our privacy-first approach ensures your browsing remains private.
