Bookmark Lock – Encrypted Bookmark Vault

Lock your bookmarks behind a PIN with real AES-256 encryption. Private, offline, and free — nothing ever leaves your device.

Bookmark Lock is a vault for the bookmarks that aren't for shared screens. Locked behind a PIN, invisible until you open it. Completely free, no account required. Unlike bookmark hiders that just cover your data with a login screen, this actually encrypts it: AES-256-GCM, with the key derived from your PIN. Without the PIN, the data is unreadable — even to someone with full access to your computer and browser profile. WHAT YOU GET Real encryption. AES-256 on-device. No plaintext bookmarks, anywhere. Full vault. Folder sidebar, multi-select, bulk move and delete, drag bookmarks onto folders, sort by name or date. Quick popup. Click the icon to save the page you're on or open something you saved. Recovery code. A one-time backup if you forget your PIN. No account needed. Encrypted sync. The vault syncs via your browser's built-in sync — new machine, just your PIN. Instant search. Find any bookmark as you type. Disguise mode. When locked, looks like a notes app. Full vault tab drops to a neutral title. Activity log. See what you've opened and when. WHY USE IT Completely free — no subscriptions, no paywalls. 100% local — no backend servers, no data sent anywhere. A private alternative to Chrome's built-in bookmarks. No third party learns which sites you saved — favicons shown locally, not fetched. PRIVACY No account, no sign-in, no subscription, no ads. No servers — zero network requests, for your data or anything else. We never see your PIN, your recovery code, or a single bookmark. Everything stays on your device. Encrypted backups only.
