On Qwant you have the option to define different settings (language, type of search, suggestions, filtering, elements displayed on the home page…) by clicking on the wheel-shaped icon on the bottom right corner of the screen.
If you always use the same computer or mobile phone, these parameters will automatically be saved on your device.
But if you use different devices, you can use you customized URL. You will find in the parameters a customized URL which you just need to copy and paste. It summarizes all the options which you have set. Memorize this URL to access Qwant and you will get back the service as you like it.
