Hello. It’s impossible to close the Clemz tab on Chrome. I’ve tried closing Vinted, closing the browser, but as soon as I open it, it keeps running even at night when the computer is closed, it sends messages! How can I stop this?
Hello,
Clemz cannot run when the browser is inactive/when it is closed. (The extension does not have the ability to perform actions without your authorization)
As we do not have information about your Clemz account on the forum, can you please contact us at support? Bonjour@clemz.app 
Feel free to send us screenshots (or videos)
Do you use any other software? 
Thank you for your quick response. I suspect it might not be possible, but my computer is turned off at night, and I have emails sent at 4 a.m…
Did you use another Vinted extension besides Clemz, before? Or perhaps at the same time?
If so, uninstall the other Vinted-related extension(s) besides Clemz.
In my opinion, you should definitely not use multiple Vinted extensions, especially since some run in the background as soon as you open Chrome (or another browser) like (beep) (beep) or (beep)
No, I’m not going to name them 
No, no other apps!!
