Privacy policy

Effective October 22, 2026 · applies to the Bookage browser extension

The short version

Your bookmarks never leave your browser. Bookage has no servers, no accounts, no analytics, no ads and no tracking. Nothing you do in it is sent to us or to anyone else, except one thing you can choose to turn on: carrying your choices to your other computers through your own browser account's sync, encrypted with a code only you have.

What it reads and stores

• Your bookmarks (the "bookmarks" permission): to show them to you, suggest where they belong, and rearrange them to match what you do in Bookage. With Live on (the default) each change you make in Bookage is applied to your bookmarks right away; with it off, only when you press Apply. It changes bookmarks only in response to your own actions, and Undo puts the last change back.
• Your choices (done, Inbox, Trash, folders, renames, which folders to scan, settings): saved in the extension's own storage inside your browser ("storage" permission). They are not synced or uploaded anywhere, unless you turn on Carry my choices (below).
• Site icons (Chrome, Edge, Brave and other Chromium browsers): read from the browser's own icon cache. No network request is made for them.

Optional: link and safety checks

Only if you turn them on (you'll be asked for access to "all websites"):

• Link checks visit each of your bookmarked pages to see whether it still works, the same way your browser would if you opened it, but without sending your cookies or logins. The only thing those sites learn is that their page was requested. Addresses on your home network (routers, printers, anything local) are never visited.
• Safety checks download two public lists of known malware and phishing addresses, from URLhaus (abuse.ch) and OpenPhish, and compare your bookmarks against them on your device. Your bookmarks are never sent to those services.

You can leave these off; everything else works without them.

Optional: carry your choices to your other computers

Off until you turn it on (More → Carry my choices), separately on each computer. When on, Bookage keeps a summary of your decisions in your browser's own sync storage, so your other computers with Bookage get them too: which bookmarks are done, dismissed alerts, declined moves, which folders get scanned, and your sorting rules.

• Encrypted before it leaves your computer (AES-GCM), with a random code made on your first computer that you type once on the others. The code is never synced or sent anywhere, so Google, Mozilla and we cannot read the summary. What the sync service can see is that an encrypted block exists, roughly how big it is, and when it changes.
• Inside the encrypted summary, bookmarks are identified by a short fingerprint of their address, not the address itself.
• It travels with your Google or Firefox account's sync, the same way your bookmarks do. It never reaches us.
• Turning it off offers to remove the shared copy from your account. Whether a sync service keeps older copies on its own servers is up to that service; they stay encrypted either way.

Optional: on-device AI suggestions

In browsers that include a built-in AI model (currently Chrome, on capable computers), the Ask on-device AI button lets that model suggest folders. It runs entirely on your computer: bookmark titles and addresses are given to the browser's local model and are not sent anywhere. The browser downloads its model once, the first time any extension or site uses it.

What we never do

• Sell, share, or transfer your data. We don't receive it in the first place.
• Use your data for advertising, credit-worthiness, or anything unrelated to sorting your bookmarks.
• Load code from the internet: everything the extension runs ships inside it.

Deleting your data

Uninstalling the extension deletes everything it stored on that computer (to remove a shared copy of your choices from your browser account, turn Carry my choices off first and choose to remove it). Your browser's actual bookmarks stay exactly as they are at that moment.

Changes and contact

If this policy ever changes, the new version will be posted on this page with a new effective date. Questions: open an issue.
