Another way to save yourself some time is to not add any localizations to your app until you actually need to. In updating PuppyCam this time around I hit a roadblock because my privacy URL was no longer valid so I set up a subdomain specifically for the app just as I had for my more recent apps. I use a three page template to cover support requests, my cookie and privacy policies. Upon providing that new url to Apple and hitting the submit button I got an error indicating that I had to provide a privacy URL for every localized language. Nope, that’s a serious load of work when 90% of my users are in English speaking countries according to Firebase. So those languages are now removed.
Don’t worry about those non-English speaking users though, the app’s functionality didn’t change and there is no text in the app that isn’t localized for them already.
