I asked them to delete my data, they said "Install our app"

No, it’s not at all legal for the company to do this. Reply and remind them they have one calendar month to comply from the date of your original request, otherwise you will make a complaint to which ever information regulator is correct for the juridiction they’re operating in.

For now, I do not want to announce the name of this company publicly.

If they won’t want to resolve it friendly, then I will do so.

They already said they don’t want to.

They asked you to install the app on purpose, in hopes that you’ll decide it’s too much hassle and decide not to delete the account.

How do you know this?

My first thought was “they probably want to ensure they are who they say they are and so want an authenticated request” - while that’s against GDPR, not everyone is as educated as they should be, and not every mistake is a nefarious activity.

The individual responding isn’t the issue. They haven’t made any decision to respond like this, they are following a script.

The script is written by people who should know exactly what they are doing, so the result is either malice or negligence. Either way it’s unacceptable where the law is concerned.
