Do you know a Privacy friendly blue light filter ? Preferably a desktop app but firefox extentions are OK

    BTW for Android, there are 2 kinds of blue light filters, both are available on F-Droid:

    • Those that recalibrate the display via KCAL. If your OS has one built in, it’s almost always one of these. If it doesn’t, root is required to install it. Recommended: Night Light
    • Those that display a fullscreen overlay. Root is optional but you cannot cover the keyboard and status bar without it on modern Android versions (and hide the overlay from screenshots), and old ones don’t support multichannel alpha so a color filter will actually make dark areas lighter. However, if you’re a root user of Android 10 (and maybe some older versions I didn’t test), the filter works perfectly. Recommended: Red Moon
