The way the extension works is by taking a screenshot of the users current window, identifying where the board is in the user's screen, and then using OCR to read the board. As such, the user must consent to making the contents of their screen be available. The screenshot will only be taken when the user consents by pressing the scan button in the chrome extension and will never run in the background or when the user is unaware of it. The data will never be stored or shared in any shape or form. Privacy is incredibly important and we promise that the only use of the scan feature is to find and identify the sudoku board automatically.
