Privacy Policy

Covers both the Postmark web tool and the Postmark Chrome extension. Last updated August 2026.

What Postmark is

Postmark is a free tool by LOGOBBY that decodes the exact publish time of a LinkedIn post from its own post ID, and — through the optional Chrome extension — reads reaction and comment counts from your own LinkedIn activity page.

What data Postmark accesses

Web tool: the numeric ID embedded in whatever LinkedIn post URL or ID you paste in. Nothing else.
Chrome extension, when you click "Extract from this LinkedIn tab": the reaction counts, comment counts, and post IDs visible on your own LinkedIn activity page, read directly from the page you are already logged into.

What Postmark does with that data

All decoding and extraction happens locally in your browser. Postmark has no backend server, and nothing you paste, decode, or extract is ever transmitted to LOGOBBY or to any third party.
Extracted data lives only in your browser session (the page tab, or the extension's popup while it's open) plus your local clipboard if you use a "Copy" button or download a CSV. It is not persisted anywhere by Postmark itself.

Analytics

The postmark.logobby.com website (not the Chrome extension) uses Google Analytics to understand overall traffic — for example, how many people visit, which pages they view, and general location/device information derived automatically from that visit. This is standard website analytics, separate from Postmark's actual decoding/extraction features described above: it never sees anything you paste into the tool or anything read from your LinkedIn activity page.

Google Analytics uses cookies and may collect data such as your approximate location (from IP address), browser and device type, and pages visited. See Google's Privacy Policy for details on how Google handles this data.

Chrome extension permissions

activeTab / scripting — used only to run the extraction on the LinkedIn tab you explicitly click "Extract" on.
host_permissions (linkedin.com) — required so the extraction can read post timestamps and engagement counts from the page you're viewing.
clipboardWrite — used only for the "Copy" buttons in the interface.

The Chrome extension itself does not use Google Analytics or any other analytics — it has no network access beyond linkedin.com, and everything it reads stays inside your browser.

Third parties

Postmark does not share, sell, or transmit any of the data you paste, decode, or extract to third parties — that part of Postmark has no backend and never leaves your browser. The one exception is standard website analytics (Google Analytics) on the postmark.logobby.com site itself, described above. Postmark is not affiliated with, endorsed by, or officially connected to LinkedIn Corporation or Google in any way.
