Can I remove a language from localization?

My iOS app (paid app) is currently localized to ten different languages. However, some of the languages are not justifying the required ongoing efforts to support them.
I therefore wish to remove a specific language, but I wonder if there are any basic rules or limitations about removing a language from an app. For example, am I required announcing the removal in some place (e.g. App Store or my website), for a predefined time period (e.g. one year ahead of removal)

I can easily envision a case where a user who just purchased the app with support for her native language, have the app suddenly appear in English on the next update from the App Store. And that after paying nicely for the app and putting the efforts to build its database. That would obviously frustrate the user.

Any thoughts about how to deal with this?
Very late reply, and I will seek a final answer as I'm in the same boat.

I do recall many years back that developers were not allowed to remove localizations as that was deemed removing functionality. I'm hoping this will now be allowed.

I localized my main app to eight other languages I believe back in 2011. But these days, the income made outside the US and Canada is effectively zero. And, I have yet to recoup the costs for these localizations.

This is ultimately preventing me from adding new features to the app as my income per year is far less of what the additional localization work would cost (since I need eight languages).
I would advise the following:
  • mention clearly in the section for "new release information" the language you suppressed.

  • maybe you could also remove the most concerned countries from list of available countries.

  • you could also issue one more release with all languages and then, if running in the language you intend to suppress warn user that this is the last version to support this language.

Unfortunately, Claude, any modifications to metadata or messages in the app itself would need to be localized as well. The cost of this is just too high and cannot be justified. I'm still awaiting a response from Apple. Hope to have information soon.
Never got a reply from Apple, so got them on the phone today. Unfortunately, I still don't have a definitive answer to "is there, or isn't there a policy still in place that disallows developers from removing localizations in app updates."

The person fielding my call ended up putting me on hold while they spoke with a senior advisor, and then oddly sent me email instructions on how to edit metadata in itunesconnect. Sad state of affairs.

So I then took it upon myself to just create a new version for my app in itunesconnect. I then noticed that if I hoevered over the languages in the upper-right popup menu, there's a delete icon as you hover over the right side of each localization name.

So I removed all except for English (my default and dev language). Pressed on Save. But, when returning to that page later, all the localizations for the new version were still there. So I performed the removals a second time and this time it stuck. Even when logging out, then back in. So definitely a bug in itunesconnect.

Having said all that, I'm still months away from having an update for my main app, so I ultimately do not know if Apple will approve this version. I just wish we could get a straight answer from Apple ahead of time so we don't waste any time.

The exact issue persists to this day. Trying to remove a localization causes an error, and changes can't be saved. This is somewhat irritating, as while my app is localized to numerous languages, updating the texts on App Store Connect for each version is an unneeded hassle.
