This policy covers the Chess Live Tools browser extension for Chrome, Edge, Brave, Firefox and other compatible browsers.
Short version: Chess Live Tools does not collect, sell or share any data. Everything it uses stays on your own computer, and it sends nothing to us or to anyone else.
What the extension uses, and where it stays#
| Data | What it is used for | Where it goes |
|---|---|---|
| Your OBS WebSocket password | Connecting to OBS Studio on your own computer. | Saved only in your browser’s local extension storage. Sent only to OBS at 127.0.0.1 / localhost. |
| Board position on chess.com | The position and size of the chessboard and player bars on the page, so the OBS crop can match them. | Kept in memory and sent only to OBS on your own computer. |
| OBS capture preview | During setup, the extension looks at OBS’s own preview of your capture to find your browser window. | Analysed in memory and never saved or sent anywhere. |
| Your settings | Which OBS scene items to crop, the OBS address, and whether auto-crop is on. | Saved only in your browser’s local extension storage. |
The extension does not read your moves, chat, messages, account details, browsing history or any other website. It only works on chess.com pages.
What we never do#
- No analytics, tracking, advertising or cookies.
- No accounts, and no servers of our own: the extension never contacts chesstok.com or any other remote server.
- No selling or transferring of data to third parties.
- No use of data for anything other than cropping your board in OBS.
- No use of data to determine creditworthiness or for lending.
Network connections#
The extension connects only to the OBS WebSocket server on your own computer (ws://127.0.0.1 or ws://localhost). It refuses any other address.
Permissions#

- scripting: start the board measurer in chess.com tabs that were already open when the extension was installed or updated.
- localhost / 127.0.0.1: talk to OBS on your computer.
