Session Vault: Tab Session Manager & Backup

Session Vault is a session manager that never loses your tabs. Save every window, tab and tab group in one click, let autosave run in the background, and get automatic backup files so a crash, a browser update or a bad sync can never wipe your sessions again.

WHY SESSION VAULT • Crash recovery: after a crash or restart, press "Restore previous session" in the toolbar popup and every window comes back. • Autosave every 5 minutes (1–60, your choice) and a few seconds after tabs change. Identical snapshots are never stored twice, so it stays light even with hundreds of tabs. • Automatic backup files, free: a full JSON backup in Downloads/SessionVault every day (or every 6 h / 12 h / weekly). The last 7 are kept and only files created by Session Vault are ever rotated. • Tab groups done right: group names, colours and collapsed state are saved and restored, together with pinned tabs and window size and position. • Data integrity you can check: every write is an atomic database transaction with a SHA-256 checksum, the last 3 versions of every session are kept, and the Storage health page verifies everything on demand.

FREE FEATURES • Save the current window or all windows; unlimited saved sessions • Restore a whole session, one window or one tab, in new windows or the current one • Lazy restore for big sessions (tabs load when you click them), so your computer doesn't freeze • Pages the browser won't let extensions open (chrome://, about:, local files) are kept as a placeholder with a copy button, never silently lost; you get a summary like "47 of 48 restored; 1 blocked: chrome://settings" • Dashboard with instant search by title and URL across thousands of saved tabs • Organise: rename, tags, notes, pin, merge, split by window, remove duplicates, drag & drop tabs between windows • "Already saved in…" indicator for the current tab • Autosave history: last 30 snapshots + 10 previous sessions • Import from Session Buddy, OneTab, Tab Session Manager, URL lists, Markdown and bookmarks HTML, with preview and de-duplication • Export to JSON, HTML (bookmarks), Markdown, CSV and plain text; copy as links or Markdown • Keyboard shortcuts: Alt+Shift+S save all, Alt+Shift+R restore previous session, Alt+Shift+D open the dashboard (configurable) • Light and dark mode, English and Spanish

DEEPYZE PRO (optional subscription) • Unlimited autosave history with 7 / 30 / 90 / 365-day retention • Timeline: what you closed and when, and restore from any point • Backup and restore in your own Google Drive (drive.file scope: Session Vault only sees the files it creates) — also on another computer • Password-encrypted backups (AES-GCM 256, PBKDF2) • Compare two sessions or snapshots • Named auto-save rules: daily at a time, every N minutes or on browser start One subscription unlocks every Deepyze extension. Pro features are visible with a lock; nothing is hidden and the free version is never nagged.

PRIVACY Local-first: your sessions stay in this browser profile (IndexedDB). No account, no analytics, no tracking, no ads. The only network calls are the Pro licence check with Lemon Squeezy (licence key + an instance id) and, only if you connect it, your own Google Drive.

FAQ • Does it sync? Saved data is local. With Pro you can back up to your Google Drive and restore on another computer. • Where are my backups? Downloads/SessionVault (optional "Manage downloads" permission, asked once). • Incognito? Ignored by default; you can include private windows in Options if the browser allows the extension there. • Firefox and Edge? Yes, the same extension runs on Chrome, Edge and Firefox (tab groups where the browser supports them).
