If you mean auto pause, it does all that on the web site after you upload. It does it for anything whether tracked on their app, or with another phone app, Garmin etc. You don’t need to use auto pause yourself if you have the option on non Strava apps and devices.
Personally I don’t see why you’d want to pause it. Yes you may want to track moving only for overall time, but when it comes to Strava it’s all about segments. If you stopped during a segement to eat lunch and then finished the segment, it could be logged as doing it in 1 minute, when you actually took 1 hour. Thankfully Strava deal with this anyway, ignoring auto pauses in segments and working on entry and exit times, and yet counting the moving time total whether or not you have any pause function enabled.
That said there are some apps and devices which can confuse it with auto pause enabled and I’ve had old rides with impossible KOMs on climbs (2s climb, when it took me several minutes, because it auto paused due to slow speed or even pushing up). It’s just better then to disable auto pause.
