Markdown Table Generator ("the extension") is a Chrome extension that turns rows and columns into a Markdown table you can paste anywhere.
What we collect
Nothing. The extension has no backend, no account system, no analytics and no telemetry. We — the developer — never see the data you type, paste or grab. There is no server to receive it: the extension makes no network requests at all, which you can verify in Chrome's DevTools Network tab and in the source, where a test fails the build if a network call appears.
These web pages
This page, the welcome page and the uninstall page are ordinary websites hosted on GitHub Pages, and they use Google Analytics to count visits — that is how we know how many installs happened. The extension itself sends nothing: the analytics tag lives on these pages only, never inside the popup, and it never sees a table you build.
What the extension stores
One draft of the table you are working on, in the localStorage of the extension's own popup, inside your browser profile on your own computer:
- the cell values you typed, pasted or grabbed;
- the alignment of each column and the state of the header row switch.
The draft stays until you press Clear, and removing the extension removes it along with everything else the extension keeps. Nothing is uploaded anywhere.
Permissions
activeTab— lets the extension read the tables of the page you are on when you press Grab, and only then. Without a press it has no access to any page.scripting— runs the one-off script that reads those tables. It is injected on the Grab press and does nothing else.
The extension asks for no host permissions and installs no content scripts, so it cannot watch the pages you visit.
What the extension reads on a page
When you press Grab, the extension reads the text of the table elements of the page in the active tab: the cell values, and how many rows and columns each spans. It does not read anything else on the page, does not change the page and does not keep a copy of it. If the page has several tables, the list you pick from is built from their captions or first cells, in the popup, on your machine.
The clipboard
Pressing Copy writes the Markdown block to your clipboard. Pasting into the grid reads what you pasted, in the popup only. The extension never reads your clipboard on its own — the browser hands it the pasted text as part of your paste.
Third parties
The extension integrates with no external service, bundles no third-party library and loads nothing from the network. No data is sold, shared or disclosed, because none is collected.
Children
The extension is a writing tool for documentation, notes and issues. It is not directed at children and collects nothing from anyone.
Changes
If a future version starts handling data differently — for example an optional sync of saved table templates — this policy will be updated before that version ships, and the change will be described in the extension's store listing.
