Privacy policy

This Privacy Policy governs the manner in which Chess Position Scanner ("Extension") Collects, Uses, Stores, and Shares information collected from users (each, a "User").

This privacy policy applies to:

As users of many other internet services, we recognize that privacy is extremely important. Further details of Extension's privacy policy are outlined below.

How We Collect, Use, Store, and Share the Data


When you use the Scan functionality in our Extension by opening it and clicking the Scan button, a screenshot of your active tab (or its region selected by you) is taken and sent to our servers for analysis purposes. The screenshots are sent using Hypertext Transfer Protocol Secure (HTTPS) that is used for secure communication over a computer network. The servers analyze the screenshot and respond with the recognized chess position, if any, in the FEN format. We do not store and do not share taken screenshots.

Usage statistics

We use cookies and other tracking technologies to collect and store your information to track usage statistics, for example, how many Users opened the extension. For that purpose, we exclusively use Google Analytics.

The Extension does not collect any other data than the mentioned above.

From time to time we may make changes to our privacy policy. When we do, we will revise the updated date at the top of this page. We encourage Users to frequently check this page for any changes to stay informed about them. You acknowledge and agree that it is your responsibility to review this privacy policy periodically and become aware of modifications.
