CDO Shortener Privacy Policy
What the CDO Shortener Chrome extension does with the page you are on — and, more to the point, what it does not.
Last updated September 17, 2026.
What this covers
One browser extension, and nothing else.
CDO Shortener is a Chrome extension made by WebMK. It takes the long address of a Chabad.org article and turns it into the short form — so chabad.org/library/article_cdo/aid/3208/jewish/What-Is-Shabbat.htm becomes chabad.org/3208 — and copies that short address to your clipboard, ready to paste.
The rest of WebMK's work — this website and WebMK Content — is covered by the general WebMK privacy policy. CDO Shortener is an independent tool and is not affiliated with or endorsed by Chabad.org.
What it does, exactly
It runs only when you ask it to.
Nothing happens until you click the extension's toolbar icon or press its keyboard shortcut. When you do, on that one tab only, it:
- reads the page's own address — the canonical link the page declares in its header;
- finds the article number in that address;
- builds the short address from it;
- places the short address on your clipboard and shows a tick on the icon.
Then it is finished. It does not keep running in the background, it does not watch what you browse, and it does not touch any other tab.
If the page is not a Chabad.org article — there is no article number to find — it shows a cross on the icon and does nothing else.
What is collected
Nothing.
No information leaves your browser. The extension makes no network requests of any kind — it has no server to talk to. It stores nothing, either: not the pages you have shortened, not the addresses, not a count of how often it was used. It does not read the page beyond the single link tag it needs.
There are no analytics, no crash reporting, no cookies and no identifiers of any sort. The short address it produces goes onto your clipboard, which is yours and stays on your computer until you paste it somewhere.
The permissions it asks for, and why
Chrome lists three when you install it. Each does one job:
- Read the tab you are on when you use it (
activeTab) — so it can see the address of the page in front of you, and only at the moment you trigger it. - Run a script on that page (
scripting) — the few lines that find the article number and build the short address. - Write to the clipboard (
clipboardWrite) — to put the short address there for you.
It does not ask for access to all websites, your browsing history, your bookmarks or anything that runs when Chrome starts.
Who else sees it
No one.
Because nothing is sent anywhere, there is nothing to share, sell, rent or hand over — to WebMK, to Chabad.org, or to anyone else. The extension's use of the small amount of page information it touches follows the Chrome Web Store Limited Use requirements: it is used only to make the short address you asked for, and for nothing else.
Changes, and how to reach a person
If this policy changes, the date at the top of the page changes with it. If a future version of the extension ever starts to collect anything, this page will say so plainly before that version is published.
