Extension: CrookedMarks (Chrome Web Store)
Published by: Aleksey Dorogov

Short version
CrookedMarks does not collect, transmit, sell, or share any data. Everything it touches stays inside your browser. There is no server, no analytics, no telemetry, no advertising, and no third-party code.
What the extension accesses
Your bookmarks. CrookedMarks reads your Chrome bookmarks in order to display
them, and writes to them when you add, edit, move, reorder, or delete a bookmark.
This is the whole purpose of the extension. Bookmark data is read from and
written to Chrome’s own bookmark store through the standard chrome.bookmarks
API. It is never copied anywhere else.
Your extension settings. Which bookmarks you pinned, which folders you
collapsed, your theme, density, and sorting preferences. Pins and settings are
stored with chrome.storage.sync, which means Chrome may sync them between your
own signed-in devices, the same way it syncs your bookmarks. Collapse state is
stored locally with chrome.storage.local and never leaves the machine. This
data is available only to the extension.
Site icons. Icons shown on the cards come from Chrome’s local favicon cache
through the favicon permission. No request is made to any website to fetch
them.
The current page’s address, only when you ask for it. When you use the
right-click menu item “Add this page to CrookedMarks”, Chrome hands the extension
the URL and title of that one page so it can be saved as a bookmark. This happens
only on that click, only for that page, and the value is used only to create the
bookmark. CrookedMarks does not request the tabs permission and cannot read
your browsing history or monitor the pages you visit.
Exporting a backup. When you export, the file is generated in the browser and saved through Chrome’s normal download flow to a location you control. Nothing is uploaded, and the extension does not read your downloads folder. Importing reads only the file you pick, in the page, and creates bookmarks from it.
What the extension does not do
- It makes no network requests of any kind. There is no backend to send data to.
- It contains no analytics, tracking pixels, fingerprinting, or crash reporting.
- It loads no remote code, no external fonts, no CDN scripts.
- It does not read page content, form fields, passwords, or cookies.
- It does not sell or transfer data to third parties, because it holds none.
Data retention and deletion
CrookedMarks stores nothing outside your browser, so there is nothing for us to retain or delete. Uninstalling the extension removes its stored settings and pins. Your bookmarks are Chrome’s, not the extension’s, and remain untouched by uninstalling.
Permissions and why they exist
| Permission | Why |
|---|---|
bookmarks | Read your bookmarks to display them; write when you edit, move, or delete one. |
storage | Remember pinned items, collapsed folders, and your settings. |
favicon | Show each site’s icon from Chrome’s local cache, with no network access. |
sidePanel | Render the extension in Chrome’s side panel. |
contextMenus | Add the “Add this page to CrookedMarks” right-click item. |
activeTab | Read the address and title of the current page at the moment you invoke the extension, so a bookmark can be created from it. Grants nothing at any other time. |
CrookedMarks requests no host permissions and can therefore not access the content of any website.
Children
The extension is not directed at children and collects no data from anyone.
Changes
If this policy ever changes, the updated version will be published at the same address and the date above will change. Any future version that collects data would require a new permission prompt, which Chrome would show you before the update installs.
