You're good as it will not get in Hubs or Bottom bracket. There is a possibility of it getting in your freewheel BUT ONLY if you spray directly into your Freewheel BUT that is highly unlikely.
Here's how I've been doing it for years; Using wd-40 Spray the chain about 12 inches, using a cloth as a backstop, then wipe that area with same backstop cloth. Rotate crank arms til you're on the next 12 inches and repeat. Repeat til you've completed the whole chain. Wipe with cloth one more final time. DONE. That's it. You've cleaned and lubed chain all at once. As long as You've never completely removed Manufacturers lube, this method will last about 200 to 300 miles before you need to do it again.
Bonus your chain will look like new.
Another bonus, put the backstop cloth in a ziploc bag and use it every time you do this.
Oops forgot to add, I only do this to my bikes. When I work on someone else's bike I use chain oil 😁. Why, because I can tell by the condition of their bike they're not gonna lube their chain ever again. So I try to give the chain a fighting chance.
