Quote from the lead developer Stefan

Privacy is very important for me and also for my users. And a Chrome extension must be simple and clean.

These explains more about these phrases. And what it does in your web browser.

Your data on all websites

  • Your data on all websites“:
    This means it injects a JavaScript to the current web page, know as “content.js”. The Turn Off the Lights browser extension use this feature, so it can detect the video player and track the play status for the “AutoPlay” feature.

Your tabs and browsing activity

  • Your tabs and browsing activity“:
    This means that the Chrome extension opens a welcome page when you install for the first time the Turn Off the Lights Chrome extension.

You can read more about this specific permission here on Google Chrome Developer Code’s documentation. And do not forget that the Open-Source Turn Off the Lights browser extension is available at Github. And you are free to look in the code. That is readable and not compressed.

Tip to choose and install a good extension.

It’s best to install Chrome extensions from the Chrome web store and to read the review on that extension page.
