How to turn OFF windows insider?

[lexus232]

I am on WP 8.1 GDR2 preview any my phones keeps notifying me that there is a WP10 preview available for download. How turn these notifications and Windows Insider app off so it completely forgets about WP10 preview?
Thanks in advance, guys.

Backstory:
Yesterday I thought I will try out new WP10 preview but changed my mind when read that there will be no OneNote and Office in this build, which are crucial for my daily life. Therefore decided not to install wp10 preview.

Uncheck auto download in settings + uninstall it
BTW , tell us about the performance

I uninstalled the Windows Insider app, unticked auto install (which actually wasn't set up in the first place), rebooted twice and it still offers me to install WP10 every time I boot up the phone and lists it as an available update in the "phone update" section. Thanks for help though, Fahmi Bassem.

With Preview for Devopers one could have just opt-out of preview and update notifications would have been gone, but how to do it with Windows Insider?

I had the same problem a while back. Only solution is to go into Settings and reset the device.

Sorry Lexus I thought your phone didn't download the update, now, you've to postpone any modification + make sure to set the preferred installation time to when you're using the phone, so that it won't install it automatically
