I have this on the start of my application:

LaunchedEffect(Unit) {
            while(true) {
                    delay(7000)
                    try {
                        productMap.fill(ShoppingRepository.getProducts())
                    } catch(e: Exception) {
                        productMap.fill(cache)
                        e.printStackTrace()
                    }
                }
        }

Does this get stopped when the process is not in the foreground or something?

if yes how can I like make this start again after the app gets reopened

I would say this is not really compose related question, as it seems like your use-case is to pull some data each 7 seconds from some API?

If yes I would recommend to use ProcessLifecycleOwner to observe when application goes to foreground / background.

For example you may setup the following in your Application class:

override fun onCreate() {
    super.onCreate()

    val lifecycle = ProcessLifecycleOwner.get().lifecycle
    lifecycle.addObserver(
        object : DefaultLifecycleObserver {
            
            private var job: Job? = null
            
            override fun onStart(owner: LifecycleOwner) {
                // Application goes to foreground, setup job
                job = lifecycle.coroutineScope.launch {
                    while(isActive) {
                        delay(7000)
                        // Fetch & store
                    }
                }
            }
            
            override fun onStop(owner: LifecycleOwner) {
                // Application goes to background, cancel job
                job?.cancel()
            }
        }
    )
}

You can use WorkManager; put the request for new data every 15 minutes and save it in the database.
