Privacy policy for Boon

Last updated: 9 September 2026

Boon is a Chrome extension that manages your open tabs and your saved bookmarks together in a side panel. It is listed on the Chrome Web Store as boon. This policy describes what it stores, what it reads, and what it never does.

The short version

Boon has no account, no server, and makes no network requests. Everything it stores stays in the Chrome profile on the computer where you installed it. Nothing is sold, shared, or transmitted to anyone, including the developer. The developer cannot see any of it.

What Boon stores, and why

All of this is written to Chrome's local extension storage (chrome.storage.local and chrome.storage.session) on your own computer.

1. Your settings. The colours you choose, your text size, what clicking a saved page does, whether the archive is recording and for how long, whether the drag diagnostics overlay is switched on, and which bookmarks folder Boon is using. This exists so the panel looks and behaves the way you left it.

2. Your archive of closed pages — this is browsing history. When you close a tab, and when you delete a page you had saved, Boon records that page's address, its title, the time, and (for a deleted bookmark) the folder path it was filed under inside Boon. This is what lets the panel answer “what was that page I just closed?” and offer it back to you as a clickable list.

It records tabs closed anywhere in Chrome, not only tabs closed from inside Boon.
It is on by default. One switch, under Settings → Archive closed tabs, stops it recording. Turning it off does not delete what is already stored.
Entries are deleted automatically after a period you choose: 7, 30, 90 or 365 days, or never. The default is 30 days. Whatever you choose, the archive holds at most 2,000 entries, oldest discarded first.
Only pages a click could reopen are recorded — http, https and file addresses. Chrome's own pages, extension pages, about:blank, javascript:, mailto:, data:, blob: and ftp: addresses are never stored.
Closing a tab with Boon's own minus control records nothing, because the saved page it belongs to is still there.
You can delete any single entry with the cross beside it, or empty the whole archive from the bin button in the archive header.

3. Which folders you had open, and which saved rows Boon created from a tab. This is display state, so that reopening the panel shows you what you were looking at.

4. Short-lived tab and window information. A handful of small records — the address and title of each open tab, which saved row belongs to which tab, any names you have given tabs, and where a newly opened tab should land — are held in session storage, which Chrome clears every time the browser restarts.

Your saved pages are Chrome bookmarks

Boon does not keep a private copy of the pages you save. It reads and writes ordinary Chrome bookmarks in one ordinary bookmarks folder — “Boon” in Other bookmarks by default, or any folder you choose. They are yours, they are visible in Chrome's own bookmark manager, and they remain if you uninstall Boon.

What Boon reads while it is running

To draw the list of your open tabs, Boon reads each tab's title and address from Chrome. It uses these to show the list, to match a saved page against a tab that already has it open, and — if the archive is on — to record a closed page as described above.

To show an icon beside a saved page, Boon asks Chrome for the favicon Chrome has already cached for that address. This is served by Chrome from its own local cache; Boon does not contact the website to fetch it, and receives nothing but the image.

Boon requests no access to the content of any web page. It has no host permissions and injects no scripts into pages, so it cannot read, alter, or collect the text, images, form fields, or anything else inside the pages you visit.

What Boon does not do

It does not transmit anything, anywhere. Boon makes no network requests of any kind. There is no server, no API, no analytics, no telemetry, no crash reporting, and no advertising.
It does not sell, rent, or share your data. There is no recipient to share it with.
It does not use Chrome's sync storage. Nothing is copied to your Google account or to your other computers.
It contains no cloud or Google Drive sync. The published extension asks for no sign-in permission and carries no code that could reach a cloud service.
It does not track you across sites, build a profile, or target advertisements.
It does not run any code that was not shipped inside the extension package.
It does not ask for, or hold, any personally identifying information: no name, no email address, no account.

When data leaves your computer

Only when you ask, and only to a file you choose. Settings → Backup → Save to file writes your settings and a list of your saved pages to a JSON file in your downloads folder. It is written only when you press that button, and it is the only way Boon exports anything. Your archive of closed pages is not included in it. What happens to the file afterwards is up to you. Boon does not upload it and does not read it back unless you pick it yourself with Restore.

Deleting your data

One archive entry: the cross at the end of its row.
The whole archive: the bin icon in the archive header.
Stop recording: the switch under Settings → Archive closed tabs.
Everything Boon stores: remove the extension from chrome://extensions. Uninstalling deletes its local storage, including the archive and all settings. Your bookmarks are not deleted, because they belong to Chrome rather than to Boon; delete them in Chrome's bookmark manager if you want them gone too.

Children

Boon is a browser utility. It is not directed at children and collects no information about anyone, of any age.

Limited Use disclosure

Boon's use of information received from Chrome APIs adheres to the Chrome Web Store User Data Policy, including the Limited Use requirements.

Specifically: Boon collects web browsing activity — the addresses and titles of tabs you close and saved pages you delete — only to provide the archive, which is a user-facing feature described on Boon's Chrome Web Store listing and displayed in Boon's own interface. That data is stored locally on your device and is never transmitted. Boon does not transfer this or any other user data to third parties; does not use it for advertising, ad targeting, retargeting, personalisation, or any purpose unrelated to the feature above; does not use it to determine creditworthiness or for lending purposes; and does not allow any human to read it.

Changes

If this policy changes, the date at the top changes with it, and material changes will be noted in Boon's Chrome Web Store listing.

Issues are public. Please do not include anything private in one — there is nothing about your Boon data that the developer could look up anyway.
